How Much Does an Off-Grid Power System Really Cost?

Posted on by Adam Lewis

Can’t get connected to mains electricity? Quoted thousands to upgrade grid capacity? Or maybe your business keeps losing power whenever the grid goes down. For many homes, farms and estates, rising bills and standing charges are another constant frustration.

That’s why more people are turning to off-grid power systems, producing their own electricity with a mix of solar, batteries and backup generation. But how much does an off-grid power system actually cost?

The answer depends on your site, your energy needs and how you want your system to work. Below, we break down the key cost factors, the savings compared to grid electricity and what to consider when weighing up the investment in an independent power supply.

The true cost of grid power vs going off-grid

When you’re weighing up energy options, it’s not just about what you pay today. It’s about what you’ll be paying (and dealing with) for years to come. Here’s how on grid and off-grid power compare:

Staying on the grid

  • Connection costs: For remote plots, new connections can range from tens to hundreds of thousands of pounds once cabling, poles, transformers and wayleaves are included. In our experience, the average connection cost is around £70,000.
  • Ongoing bills: You’ll pay unit rates and standing charges and remain exposed to price rises. With current average standing charges around 60p per day and having risen roughly 10% per year over the past decade. That’s nearly £24,000 over 25 years just to stay connected, before using any electricity. You’ll pay unit rates and standing charges and remain exposed to price rises.
  • Hidden costs: Outages cause downtime, disruption and sometimes spoilage or equipment issues.

Going off-grid

  • Upfront investment: You buy your own ‘mini power station’ – generation (often solar + backup generator), battery storage and intelligent control.
  • Ongoing savings: For full off-grid, no electricity bills or standing charges. Fuel is only for short generator top-ups in a correctly designed hybrid system.
  • Stability: You’re insulated from future price hikes and grid constraints.

Bottom line: Grid = lower upfront (if already connected) but forever bills. Off-grid = higher upfront, far lower ongoing costs, coupled with ongoing price and power certainty. Once installed, solar energy generation costs are effectively zero thereby protecting you against inflation and future electricity price rises.

Off-grid system costs: cost breakdown

When you invest in an off-grid system, you’re not just buying a box of parts. You’re building your own reliable power station. One that is tailored to your site, your energy needs and your long-term goals.

Here’s some components that might be considered as part of your bespoke off-grid system:

Solar array

Often the backbone of the system. Panels, mounting (roof or ground) and wiring. More solar capacity means less generator runtime and lower lifetime fuel costs.

Battery bank

The single biggest cost driver. Batteries store the solar energy you’ll use at night or during poor weather. Options include:

  • Lead-acid: Powerguard’s preferred choice proven, robust and highly reliable. These batteries have decades of real-world testing, perform well in both hot and cold conditions and offer excellent safety. They’re also more cost-effective and easier to service over time.
  • Lithium: Available on request. Higher upfront cost but longer lifespan and lower maintenance when managed correctly.

Inverter & intelligent controls

The brains of the system. Converts DC to AC, manages charge and discharge, protects batteries and automatically starts the generator when needed. Higher-quality controls boost reliability and efficiency.

Powerguard’s own PS system has been developed and refined over 26 years to deliver maximum performance and reliability. Designed and built in the UK, it takes the highest possible yield from solar and battery inputs, minimises generator runtime and extends the life of both batteries and solar components.

Backup generator

Handles peak loads and long grey spells. Specification is critical an energy-efficient, sustainable and quiet generator keeps running costs low.

Powerguard systems use high-quality generators built around a 1500 RPM Perkins engine and Mecc Alte alternator, delivering proven reliability, fuel efficiency and long service life.

Site & installation

Access, terrain, cable runs, enclosures and local works all influence labour and balance-of-system costs.

Quality & customisation

No two sites are the same. A bespoke design may cost more upfront than an off-the-shelf kit, but it avoids oversizing, reduces waste and delivers greater reliability – saving more money over time.

Ongoing costs & maintenance

Every power system has upkeep. The difference with a well-designed off-grid setup is that it’s predictable, controlled and far lower than relying on the grid or running a generator 24/7.

  • Fuel: A backup generator only runs when solar and storage need topping up – short, concentrated cycles rather than constant operation.
  • Servicing: Like any engine, a generator benefits from routine servicing. Panels just need the occasional clean and most customers choose a simple maintenance plan for peace of mind.
  • Monitoring & support: Intelligent controls and remote diagnostics mean issues are spotted early, avoiding unexpected downtime or costly callouts.

With Powerguard systems, these modest costs are offset by the savings you make every month: no standing charges, no price hikes and no dependence on fragile grid supply.

When does going off-grid save you money?

Going off-grid goes beyond cutting bills. Although that is pretty favourable. It is also about removing costs you don’t control and replacing them with a system that pays you back in stability, resilience and independence.

  • Avoiding grid connection fees: New connections or supply upgrades often cost tens of thousands. Off-grid eliminates that expense completely.
  • Budget certainty: With your own system, you’re insulated from unit price hikes, standing charges and unpredictable bills. You’re effectively pre-paying for decades of secure electricity.
  • Resilience that protects income: No more downtime, spoilage or operational disruption when the grid fails – your system keeps running.
  • Energy independence: You control your supply, with no reliance on DNOs or hidden charges.
  • Sustainability built in: Solar can provide the bulk of your energy, with a generator running only when needed. That slashes fuel use and emissions.
  • Scalability on your terms: As your site, business or home grows, you expand your system. Not your standing charges.

In short: Off-grid power saves money both directly and indirectly while giving you reliability the grid can’t guarantee. According to UK Government data, electricity prices have risen by an average of around 10% per year for more than a decade and show no sign of slowing. As a result, well-designed off-grid systems can save hundreds of thousands of pounds in energy costs over their lifetime.

FAQs: your questions about going off-grid, answered

Thinking about leaving the grid raises a lot of practical questions, from cost to reliability. That’s normal. Every site is different and we know the decision isn’t made lightly. To help, here are answers to some of the most common queries we hear from people weighing up grid power vs. going off-grid.

Still got a question? We’ve got an answer. Contact the Powerguard team and we’ll be happy to advise.

Is off-grid cheaper than connecting to the grid?
Often, far cheaper, yes! Especially where grid connection quotes are high or capacity is limited. Off-grid turns a one-off investment into long-term savings and independence.
Do I still need a generator?
In the UK, yes. Solar can cover most days, but a right-sized, well-controlled generator ensures resilience during peaks or long grey spells.
How long is the payback period?
It depends on your load, fuel offset, and avoided grid costs. Many clients see strong savings versus ongoing grid bills or 24/7 generator reliance. Exact payback is site-specific.
What about maintenance?
Routine but straightforward: generator servicing, periodic system checks and occasional panel cleaning. Many clients opt for a maintenance plan for complete peace of mind.
Can you integrate what I already have?
Often, yes. Existing solar, generators or battery banks can be assessed and integrated where it makes sense.
Is off-grid power reliable in winter?
Yes, as long as the system is designed correctly. Solar production, for example, is lower in winter, but battery capacity and generator backup cover darker days to ensure 24/7 supply.
Can I run a business off-grid?
Absolutely. From farms to storage facilities to schools, many businesses already operate entirely off-grid. Systems are designed around your load profile to ensure operations keep running.

Your next step: get numbers that fit your site

There’s no universal price for an off-grid system because there’s no universal site, load profile or goal. The smartest way to understand cost is a tailored assessment:

  • We’ll review your usage
  • Assess your site
  • Design a right-sized system
  • Provide a clear breakdown and timeline

Why customers come to Powerguard

Keith Butter quote - powering the world

Power challenges come in all shapes and sizes, but after decades of listening to customers, Keith and the Powerguard team have seen the same pain points crop up frequently.

Here are four challenges we hear time and again – do any sound familiar?

“I can’t get connected to the grid”

Keith insight: This is more common than you’d think, especially for rural builds or international sites where Distribution Network Operator (DNO) connections just aren’t viable.

From new builds, rural properties, international projects and beyond, many sites simply can’t access a reliable DNO supply. That’s why Powerguard designs full systems that operate completely off-grid or as standalone backups.

“We don’t have enough power”

Keith insight: It’s not always about total outage, sometimes it’s just about having too little to grow. Growing operations often outpace their available capacity. Powerguard helps upgrade, supplement or redesign infrastructure to support new loads.

“We keep getting power cuts”

Keith insight: Reality is that the grid just isn’t as stable as it used to be. That uncertainty hits hardest when you’re trying to run a business. From winter storms to summer demand spikes, grid reliability is falling. Powerguard builds systems that protect your operation from the impact of blackouts.

“We want energy independence”

Keith insight: It’s about control. No more waiting on the grid, no more surprise bills; just power on your terms. Many customers want to reduce reliance on the grid entirely. With off-grid and hybrid systems, battery storage and solar integration, Powerguard delivers reliable autonomy.

Can you relate? If any of these challenges sound familiar, you’re not alone. And, you’re exactly who we’re here to help. Speak to Keith and the team here.

Emergency Backup Power for Businesses: What Are Your Options?

Posted on by Adam Lewis

From aquariums and airports to hospitals, schools and beyond, here’s how to keep critical infrastructure running during a grid power failure.

Power outages don’t always come with a warning. For high-dependency sites like healthcare facilities, data centres, airports and public venues, even a few seconds of downtime can lead to system failures, revenue loss, reputational damage – or worse, risk to life.

Having a backup generator simply isn’t enough.

In today’s energy landscape, true resilience means more than diesel alone. That’s why increasing numbers of businesses are now seeking integrated emergency backup power systems that ensure uninterrupted performance across essential services such as lighting, medical equipment, IT infrastructure, life safety systems and more.

This guide explores the most reliable backup power options for commercial and public sites and how Powerguard systems are already protecting critical operations.

Why generators alone aren’t a long-term solution

On January 24, 2025, during Storm Éowyn, Forth Valley Royal Hospital in Scotland experienced a 70-minute power outage. Despite having backup generators, a significant power surge caused both the mains and generator supplies to trip, leaving critical systems without power.

Just two months later, on March 21, 2025, a fire at the North Hyde electrical substation led to a massive power outage at Heathrow Airport. The incident resulted in the cancellation of over 1,300 flights and affected nearly 300,000 passengers. The airport’s backup systems failed to compensate for the loss, exposing vulnerabilities in relying solely on traditional generators.

Both incidents exposed a harsh truth: relying on generators alone isn’t enough.

Here’s why:

  • Delayed Startup: Generators often take time to initiate, leaving vital systems unprotected in the interim.
  • Mechanical Failure: Without rigorous maintenance, they can fail at the exact moment they’re needed.
  • Fuel Dependency: Prolonged outages can run reserves dry, while refuelling delays or supply chain issues can make matters worse.
  • Environmental Compliance: Noise and emissions from diesel units pose challenges, especially in sensitive settings like hospitals or schools.

In today’s world, backup systems need to be smarter, cleaner and fully integrated.

What are your emergency power options?

When the lights go out, every second counts. And for many commercial or public sector sites, having a basic generator just doesn’t cut it anymore. That’s why more businesses are looking at multi-layered, integrated backup systems that go beyond ‘just enough’ and deliver guaranteed continuity.

Here’s a breakdown of the most effective emergency power solutions available today and how Powerguard supports each one.

How To Get Reliable Power At My Wedding Venue

Posted on by Adam Lewis

From barn conversions to marquee setups, here’s how to keep the lights on and the celebrations running – without your wedding venue relying on power from the National Grid.

Tie-the-knot-with-uninterrupted-power-by- Powerguard

The bride steps forward. The vows begin. And the power cuts out.

I do…. not understand what’s happening. For rural wedding venues, it’s a nightmare that’s all too real. Whether you’re running a converted barn, marquee site or private estate, many countryside venues across the UK face a tough reality: limited or no access to reliable mains electricity.

Even if you’re technically connected, that single-phase supply often isn’t enough to power today’s high-demand events – lighting rigs, catering equipment, heating, EV chargers, sound systems. Grid upgrades can cost tens of thousands and still leave you vulnerable to outages during critical moments.

That’s why more venue owners are now turning to smarter, independent power setups – designed to deliver silent, seamless, uninterrupted electricity without the limitations of the National Grid.

This guide breaks down your venue’s power requirements, the risks of conventional setups and how Powerguard’s bespoke systems can help you stay switched on, all night long.

Contents:

Why do wedding venues struggle with power?

As if running a wedding venue wasn’t already hard enough. You’re juggling bookings, managing suppliers, calming nervous couples, working around the weather, handling last-minute changes – all while making every event feel effortlessly personal.

Then you have to figure out how to power it all.

If your venue is in a rural or edge-of-grid location, that’s often easier said than done. Even when your venue is connected to the National Grid, it’s usually single-phase supply. This might be fine for a farmhouse, but not for a full-scale wedding. As expectations grow, so do wedding venue power requirements and many operators now face serious limitations.

These include:

  • Limited capacity: Lighting rigs, catering equipment, sound systems and marquee heating easily exceed what the grid can deliver
  • Unreliable infrastructure: Remote lines mean more outages and voltage dips. One flicker can trip equipment or cut the music mid-ceremony.
  • High upgrade costs: Boosting supply isn’t simple. Venue electricity upgrade costs can top £50,000 and take months to complete.
  • No grid access at all: For barn venues or outdoor setups, the question becomes: how do you power a wedding marquee without mains electricity?

If you found yourself nodding along or saying “yes, yes, yes” like someone being proposed to, then you’ll definitely want some of what we’re having.

Spoiler: it’s not a rom-com. It’s just a reliable power supply that doesn’t bail when the music starts.

Are generators alone enough for wedding venues?

When faced with power challenges, many venues get wed to the most obvious quick fix: a diesel generator.

This is understandable. After all, it works… to a point. But as you already know, generator hire for weddings isn’t always the romantic solution it sounds like.

For many venues, they feel like the only viable option. But having helped many wedding operators tie the knot with reliable power, we know firsthand they’re far from ideal. Especially if you’re aiming for peace of mind, dependable performance and sustainability – both financial and environmental.

Here’s why:

  • Fuel costs add up fast: Diesel prices are volatile and running a generator for a full event day can burn through litres per hour – especially with catering, lighting and AV running at once.
  • They’re noisy: Even “silent” generators still hum and rattle, which can disrupt the atmosphere (and your licence if you’re in a noise-restricted area).
  • They’re high maintenance: Literally. You need regular servicing, fuel deliveries, safety checks and someone on-site who knows what they’re doing.
  • They’re not exactly green: For venues looking to promote sustainable wedding power solutions, a diesel generator isn’t the best look. You’ll be burning fuel just to keep the fairy lights on.
  • They’re not smart: Standard generators run continuously, even when your venue only needs partial power. That’s wasted energy, wasted fuel and unnecessary wear.

In short: generators are a quick fix, not the kind of power you settle down with long term.

What alternative systems are there to reliably power my wedding venue?

When it comes to powering a wedding venue, you don’t have to engage in fragile workarounds or noisy generators. There’s a better way – and that’s where Powerguard comes in.

From our UK-based manufacturing facility, we build bespoke off-grid power systems that give wedding venues complete control over their electricity, without relying on the National Grid. Quiet, scalable and engineered for reliability, our systems are trusted by rural businesses across the UK to deliver seamless power, day and night.

How do off-grid power systems work?

While every Powerguard off-grid system is tailored to your venue’s unique requirements, each comprises several components to ensure complete efficiency. Let’s take a look:

  • Battery Storage: Stores energy and powers your venue silently during regular use
  • Smart Control System: Automatically manages supply and demand, charging batteries and switching power sources as needed
  • Efficient Backup Generator: Only runs when necessary, dramatically cutting fuel use and noise
  • Optional Solar Integration: Add clean, renewable energy to reduce generator runtime and boost your sustainability credentials

Each system is fully programmed to be automated, requiring minimal maintenance all while providing stable, round-the-clock power, even in the most remote locations.

What are the benefits of going off-grid at my wedding venue?

Off-grid goes beyond energy independence. It delivers a banquet of benefits for your venue. From lower operating costs, better guest experiences and greater value, in the long term these systems effectively pay for themselves.

Here’s what you gain with a Powerguard system:

  • Reliable, 24/7 electricity with zero interruption
  • Significant fuel savings and reduced maintenance
  • Low-noise operation which is ideal for sensitive locations or late-night licences
  • Sustainable wedding power solutions that reflect your brand’s values
  • Scalable capacity as your venue grows

Whether you run barn weddings, marquee receptions or full-site glamping weekends, we build around your real-world usage rather than a generic template.

What if I’m already connected to the grid, but it’s not enough?

Not every rural venue is completely off-grid, but many are still underserved by the grid they do have. Maybe you’ve got a connection, but it can’t handle your full event load or you’re paying premium rates for power you barely trust.

That’s where Powerguard’s grid-backed hybrid systems come in.

These systems use the same advanced technology as our fully off-grid setups – smart control, battery storage and optional solar – but they’re designed to work with an existing grid connection, using it as a backup rather than a primary supply.

How it works:

Solar panels and batteries cover the bulk of your usage
Our intelligent PS System manages the energy flow
The grid steps in only when absolutely necessary
You avoid peak-rate bills and dramatically reduce your dependency on unreliable supply

This setup is ideal for venues that want to stay connected, but want to take control. It means you, and your guests, can avoid unexpected outages or runaway energy costs. You get the reliability, cost-efficiency and sustainability of an off-grid system, without disconnecting entirely.

Already connected? Still frustrated? We’ll build a system that works with your grid, not against it.

FAQs: reliable power for wedding venues

Got questions about reliable power for your venue? You’re not alone. Here are some of the most common queries we hear from wedding venue owners looking for dependable, grid-free solutions and what you need to know.

Can I power a wedding marquee without mains electricity?

Yes. A properly designed off-grid system with battery storage and a smart control unit can power everything from lighting and AV to catering equipment, even in remote outdoor setups.

Is an off-grid power system reliable for large wedding events?

Absolutely. With the right battery capacity and generator backup, off-grid systems are more stable than many rural grid connections and won’t cut out during key moments.

How much does it cost to upgrade the power supply to a rural venue?

It varies, but many venue owners report costs of £40,000 – £80,000 for grid upgrades, not including delays. Off-grid systems can be a more cost-effective and flexible long-term option.

What to Do When You Can’t Get Enough Power from the Grid

Posted on by Adam Lewis

If you can’t get enough power from the National Grid for your plans, it can leave you feeling powerless in more ways than one.

You’ve expanded your business, installed new machinery, added EV chargers or started a barn conversion project, only to discover that your existing mains electricity supply can’t cope. Sounds familiar? Don’t worry, you’re not alone. In fact, it’s a surprisingly common problem.

At Powerguard, we work with businesses and homeowners across the UK who are facing the same frustrating issue: they’re technically ‘on-grid’, but the supply isn’t strong enough to power their needs.

So what can you do when the grid can’t give you more?

You’re Connected to the Grid – But It’s Not Enough

Just because your commercial or domestic premise is connected to the National Grid doesn’t mean you’re getting all the power you need or the reliability you expect. In reality, this is one of the most common issues Powerguard helps to solve.

There are several reasons your existing grid connection might fall short:

Limited Grid Capacity – Rural Areas

In rural and semi-rural areas, the grid infrastructure is often old, overloaded or simply not built to handle modern energy demands. You may find that there’s physically not enough electricity available to supply your property, especially during peak periods when demand is high across the network. This is particularly frustrating for businesses trying to grow or diversify operations, only to be told, “Sorry, the grid can’t deliver more”.

Urban Energy Pressure

Even in cities, grid capacity is being pushed to its limits. With increasing pressure from electrification – including EV chargers, heat pumps and digital infrastructure – urban businesses are turning to backup systems and energy independence strategies to stay resilient. Events like the Heathrow Airport outage in March 2025, caused by a fire-related grid disruption, highlight how even well-connected locations can be vulnerable to sudden power loss.

Export or Supply Restrictions

Even if you’re generating your own electricity through solar panels, you may find that the local Distribution Network Operator (DNO) restricts how much you can export or even how much additional load you can draw from the grid. This can prevent you from installing more solar, expanding your setup or taking advantage of newer energy-efficient technologies.

Delays and High Costs for Upgrades

If you do apply for a grid upgrade, be prepared for delays. In some areas, DNOs are quoting timelines of 12–24 months (or longer), especially for three-phase power. And the cost? We’ve spoken to customers quoted tens of thousands of pounds for the privilege, with no guarantee the supply will meet future needs.

Risk of Power Outages

Power cuts are increasingly common, particularly in rural areas affected by storms, falling trees, network faults or ageing infrastructure. When your business depends on refrigeration, heating, IT systems, security or 24/7 access, downtime is inconvenient, costly and, in some cases, dangerous.

In short:

The grid might be there, but it can’t always grow with you. And even when it’s working, it may not be working for you.

What Are Your Options?

When the grid can’t keep up, you’ve got three choices:

❌ Option 1: Wait for a Grid Upgrade

You can apply for increased capacity from your DNO, but this can be a long, frustrating process and there’s no guarantee it will be approved or affordable.

❌ Option 2: Scale Back

You could limit your operations, put plans on hold or avoid growing your business. But that’s rarely a satisfying solution.

✅ Option 3: Take Control with an Off-Grid System

With an off-grid power system, you can supplement your grid supply or replace it entirely. You generate, store and manage your own electricity with no restrictions.

How Off-Grid Power Solves the Problem

At Powerguard, we build bespoke off-grid systems that include:

  • Solar panels sized to your actual energy use

Off-Grid Power Systems in the UK – 2025 FAQ

Posted on by Adam Lewis

We understand you have questions about going off-grid. Choosing to generate your own electricity – especially without being able to fall back on a connection to the National Grid – can feel like a big step. Whether you’re building a remote home, running a rural business or just want reliable power where the grid can’t reach (or keep up), you probably have a few questions.

You’re not alone. Most of our customers come to us with similar concerns.

At Powerguard, we’ve been designing and building off-grid systems for over 25 years – so we’ve heard it all, and we’ve solved it all. Below, we’ve pulled together answers to some of the most common questions we get asked.

Here’s what you need to know:

1. What does “off-grid power” mean in the UK?

Off-grid power means generating your own electricity independently, without relying on the National Grid for supply. In the UK, this typically involves using solar panels, battery storage and a backup diesel generator to ensure continuous power, especially during the darker winter months. For many rural properties and farms, it’s the only practical way to achieve reliable, long-term energy independence.

This is why Powerguard specialises in designing, building and installing those very systems.

2. How does a Powerguard solar and battery system work?

An off-grid system captures sunlight through solar panels and stores excess energy in large-capacity batteries for later use. 

A solar and battery off-grid system works by:

  • Capturing energy from sunlight using solar panels.
  • Storing excess electricity in batteries for use when the sun isn’t shining (such as at night or during bad weather).
  • Using a backup diesel generator to supply power when battery reserves are low and solar output is insufficient  – particularly during winter or cloudy periods.

A Powerguard off-grid power system is self-contained and designed to meet the energy needs of your home or business without drawing electricity from the grid.

3. Is solar power reliable enough in the UK?

Yes, solar energy is viable in the UK – even with the British weather. Modern solar panels work effectively with diffuse sunlight (on cloudy days) and are sized accordingly for year-round demand.

However, because solar generation is lower in winter, battery storage and a backup generator are essential components to ensure 24/7 power reliability throughout the year.

4. Do I need planning permission for an off-grid solar power system?

In most cases, solar panel installations on domestic properties are classed as permitted development and do not require planning permission, provided they meet certain conditions:

  • Panels must not protrude more than 200mm from the roof.
  • Ground-mounted panels must not exceed specific size limits.
  • Installations must not be placed in conservation areas or on listed buildings without approval.

However, larger agricultural or commercial installations may require planning permission and any new buildings powered off-grid (like barn conversions) should check local planning regulations.

5. What are the maintenance requirements for a solar and battery system?

Off-grid solar and battery systems are generally low maintenance, but key tasks include:

  • Annual inspection of solar panels for dirt, debris and potential shading issues.
  • Monitoring battery health to ensure optimal performance and lifespan (typically 15–20 years with proper maintenance).
  • Routine servicing of diesel generators, including oil changes and load testing, to ensure readiness when needed.

Many off-grid systems come with remote monitoring, allowing faults to be detected early.

6. What are the main advantages of going off-grid?

The biggest advantage is total energy independence: no grid connection costs, no standing charges and protection from rising energy prices. 

The key benefits include:

  • Complete energy independence – no reliance on the National Grid.
  • Protection – from rising energy prices and energy supply disruptions.
  • Cost control – no grid connection fees or standing charges.
  • Reduced carbon footprint – when compared to traditional diesel-only systems.

A Powerguard system is designed for scalability – meaning you can expand it later if your needs grow – without being restricted by grid limitations or export rules.

7. What are the main challenges of off-grid living?

Important considerations include:

  • Initial setup costs – installing solar panels, battery banks and generators is a significant upfront investment.
  • System design – the system must be correctly sized for your specific needs.
  • Seasonal variation – energy usage patterns and battery storage need to account for lower solar generation in winter.
  • Maintenance planning – while systems are reliable, occasional servicing is essential, particularly for backup generators.

However, with good design and upkeep, off-grid living can be straightforward and highly rewarding.

8. Can I sell my excess electricity back to the grid?

No. The UK Feed-in Tariff (FIT) scheme has been closed to new applicants since 2019. Also, Powerguard off-grid systems are designed to be fully independent of the grid – so there is typically no connection to the National Grid, through which you could export surplus energy.

With a Powerguard off-grid solar and battery system you generate power solely for your own use. Then you store the surplus energy, again, for your own use. Every kilowatt-hour generated is yours to use as needed without restrictions. This ensures all the energy you generate is kept for your own use, maximising the return on your investment.

9. Is going off-grid suitable for homes, farms and businesses?

Yes – Powerguard systems are ideal for rural homes, farms, workshops, glamping sites and hospitality venues where reliable energy is critical. Off-grid power systems can be tailored to a wide range of uses:

  • Homes and barn conversions – needing full-time residential power.
  • Farms and rural businesses – requiring energy for irrigation, workshops, lighting and security.
  • Commercial premises – like wedding venues, hotels or holiday home locations seeking energy resilience without grid dependence.

System sizing is flexible, ensuring that each installation meets the specific needs of the property.

10. How do I know if an off-grid system is right for me?

If you face expensive grid connection costs, frequent outages or you want predictable, secure energy for a remote property, an off-grid system is likely the best solution. 

You should consider an off-grid system if:

  • Your property has no practical or affordable access to the National Grid.
  • You are looking to control long-term energy costs.
  • You need reliable, year-round power without risk of blackouts.
  • You want to reduce diesel reliance and minimise carbon emissions.
  • You plan to build in a rural area without existing infrastructure.

A professional energy audit and site survey (as provided by Powerguard) will help assess your needs and design a tailored system to meet them.
