As energy bills rise and climate concerns grow, more homeowners in Wales are looking for ways to make their homes greener, more efficient — and save money in the long run. The Green Homes Wales scheme is a major initiative from the Welsh Government, run via the Development Bank of Wales, aimed at helping households decarbonise, reduce energy use, and upgrade their homes. developmentbank.wales+3developmentbank.wales+3GOV.WALES+3
Here’s what you need to know about the scheme — and how Genfit can help you take full advantage of it if you’re considering going solar.
What the Green Homes Wales Scheme Offers
The scheme combines expert advice, financing, and grant funding. Key features include:
Retrofit Coordinators Homeowners can access an expert who assesses your home and recommends energy-efficiency and decarbonisation improvements tailored to your property. developmentbank.wales+2developmentbank.wales+2
Interest-free Loans Eligible homeowners (owner-occupied, primary residence) can borrow between £1,000 and £25,000 interest-free, over up to 10 years. For larger projects, terms may be extended. There is a repayment “holiday” for 6 months so the benefits begin before repayments are due. developmentbank.wales+2developmentbank.wales+2
Grants (Installation Grant) For certain “Eligible Measures” (including solar PV, solar PV + battery storage, solar thermal) the scheme offers grant funding to reduce out-of-pocket cost. The grant amount depends on what upgrades you choose and how much of the cost is being covered by the loan. developmentbank.wales+1
Range of Supported Measures It’s not just solar — many fabric, heating, generation, controls upgrades are supported: insulation, glazing, heating systems (air/ground/water source heat pumps), draught proofing, smart controls, etc. Solar PV, solar thermal, PV with battery, and PV + diverter / PVT are explicitly included. developmentbank.wales+2developmentbank.wales+2
It must not be a new build that hasn’t been occupied for at least 6 months. developmentbank.wales+1
Properties listed or requiring special permissions might have restrictions. developmentbank.wales+1
Why Solar Fits Well in Green Homes Wales
For many homeowners, solar energy is one of the most visible, straightforward ways to reduce electricity bills and carbon emissions. Under Green Homes Wales:
Solar PV (with or without battery storage) is an eligible generation measure. developmentbank.wales+1
Because the scheme allows a mix of financing + grants, the up-front cost burden is lower, making solar more affordable.
Adding batteries or diverters can help you maximise the benefit of solar — storing or redirecting energy so less is wasted.
Solar is more powerful as part of a package: combining solar with insulation or heating controls increases the overall efficiency and savings. Green Homes Wales encourages comprehensive home assessments to identify multiple measures. developmentbank.wales+1

Investing in solar panels is a smart move — for your energy bills, your carbon footprint, and your property value. But with the growing popularity of renewable energy, not all solar companies are created equal. Sadly, we’ve seen a rise in “pop-up” solar installers offering too-good-to-be-true deals, only to disappear months later — leaving customers with no aftercare, no warranties, and no one to turn to when things go wrong.
Here’s what you need to know to protect your investment and why choosing the right installer from the start is crucial.
Red Flags: How to Spot an Unreliable Solar Company
✅ No proven track record Be cautious if a company can’t show you completed projects, testimonials, or case studies. A solid history is essential.
✅ Too-good-to-be-true prices Solar is an investment. If it’s significantly cheaper than others, corners are probably being cut — either on the panels, the installation quality, or the service.
✅ No post-installation support A solar system isn’t just a “fit and forget” job. You need monitoring, system checks, and someone to call if anything goes wrong. Many companies offer no ongoing service, which is risky.
✅ Pushy sales tactics High-pressure sales techniques or limited-time offers are a red flag. A reputable company will take the time to understand your needs and design a system that works for you.
✅ Lack of accreditation Check if the installer is certified by MCS and registered with bodies like RECC or NAPIT. These ensure they meet high industry standards.
Why It’s Important to Choose a Company Built for the Long Term
Solar panels are designed to last 25 years or more. Your installer should be in business as long as your panels are on your roof. If they vanish in a few years, you could be left with:
No technical support
No warranty backup
No system monitoring
No one to maintain or upgrade your system
It’s not just about getting panels on your roof — it’s about who’s standing behind them in 5, 10, or 20 years’ time.

Thinking About Solar? Don’t Take Risks.
If you’re considering solar panels, choose a company that’ll still be here tomorrow. With Genfit, you’re choosing peace of mind, quality service, and a partner for the future.
As the demand for renewable energy grows, more homeowners and businesses are considering solar panels. But despite the environmental and financial benefits, solar still gets its fair share of scepticism. At Genfit, we believe in helping people make informed decisions — so we’ve taken some of the most common negative opinions about solar and put them under the spotlight.
Here’s what people say — and why it’s not the full story.
💬 “Solar panels are too expensive.”
The reality: While solar panels used to come with a hefty price tag, prices have fallen significantly over the last decade. On top of that, there are finance options available, and businesses may be eligible for tax incentives or grants. More importantly, solar panels can lead to long-term savings on energy bills, often paying for themselves within a few years.
Our take: Think of solar as an investment — not just a purchase. It reduces your reliance on the grid and protects you from rising energy prices. With Genfit, we tailor systems to your needs, ensuring the best return on your investment.
💬 “They don’t work in the UK weather.”
The reality: This is one of the most common myths we hear. Solar panels work on daylight, not just direct sunshine — and the UK gets more than enough of it to make solar worthwhile. In fact, Germany, a leading country in solar, gets similar weather conditions to the UK.
Our take: Modern panels are highly efficient and designed to generate power even on cloudy days. Our systems are engineered to suit UK conditions — and we provide realistic performance estimates so you know what to expect.
💬 “They don’t make much difference to your bills.”
The reality: Installed properly, a solar PV system can significantly cut your electricity bills — especially if you pair it with battery storage to use more of the energy you generate. And with energy prices constantly fluctuating, generating your own power provides real peace of mind.
Our take: We show our customers exactly how much they can save, based on actual usage and system performance. You’ll start seeing the benefits from day one.
💬 “They’re ugly and will ruin the look of my roof.”
The reality: Today’s solar panels are much sleeker and more discreet than older models. For those prioritising aesthetics, we offer all-black panel options and mounting systems that sit closer to the roof.
Our take: We work with you to find a design that looks smart and suits your home or business. We’ve installed systems on modern builds, period properties, schools, offices — even listed buildings (with the right permissions). With the right setup, solar can actually add to your property’s value and appeal.
💬 “It takes too long to break even.”
The reality: Most systems pay for themselves within 5–10 years, sometimes sooner depending on usage and system size. With the Smart Export Guarantee (SEG), you can also earn money by selling excess electricity back to the grid.
Our take: Every installation includes a tailored estimate showing the payback period. And because panels have warranties of 25 years or more, the long-term savings are substantial.
💬 “They require too much maintenance.”
The reality: Solar panels have no moving parts and require very little maintenance. Occasional cleaning and checks are usually all that’s needed to keep them working efficiently.
Our take: We provide system monitoring and maintenance support, so you can rest easy knowing your investment is protected. If issues arise, we’re only a phone call away.
Final Thoughts
It’s normal to have questions and doubts — but many of the concerns about solar are based on outdated information or misunderstandings. At Genfit, we’re here to offer honest advice, tailored solutions, and reliable installations that make solar simple.
If you’re considering switching to solar but still have questions, get in touch with our team. We’ll walk you through the pros, the cons, and everything in between.
Intro: If you’ve heard about solar energy but aren’t sure what a “solar PV system” actually is, don’t worry, you’re not alone. Whether you’re a homeowner thinking about cutting your energy bills or a business looking to reduce your carbon footprint, understanding the basics is the first step.
In this beginner-friendly guide, we’ll explain exactly what a solar PV system is, how it works, and what you need to know before installing one.
1. What Does ‘PV’ Stand For?
PV stands for Photovoltaic. A solar PV system uses photovoltaic cells (usually in solar panels) to convert sunlight into electricity.
These systems are different from solar thermal systems, which use the sun to heat water. Solar PV is about generating electricity, for powering your lights, appliances, devices, and more.
2. What Are the Main Parts of a Solar PV System?
A typical solar PV setup includes:
Solar Panels: Usually mounted on your roof or a ground frame, these panels capture sunlight and generate DC electricity.
Inverter: This device converts the DC electricity from the panels into AC electricity, the type your home or business uses.
Generation Meter: Tracks how much energy your system produces.
Battery Storage (Optional): Stores excess energy so you can use it later, for example, at night or on cloudy days.
Export Meter (for SEG): Allows you to export unused electricity back to the grid and get paid via Smart Export Guarantee (SEG) schemes.
3. How Does a Solar PV System Work?
Here’s a simple step-by-step breakdown:
Sunlight hits the solar panels, generating DC electricity.
The inverter converts it into usable AC electricity.
Your property uses this electricity to power lights, appliances, etc.
Any unused energy is either stored (if you have a battery) or sent back to the grid.
You draw electricity from the grid only when needed (like at night or in winter).
4. Do Solar Panels Work When It’s Cloudy or Raining?
Yes, solar panels still work in cloudy weather, just at reduced efficiency. In the UK, a well-installed system can generate electricity all year round, even on overcast days.
5. How Much Space Do I Need?
A typical UK home solar PV system (around 3.5kW–4kW) needs roughly 15–20m² of roof space. Larger systems for businesses or public buildings will vary depending on the energy demand and available space.
6. What Are the Benefits of Solar PV?
✅ Lower energy bills
✅ Reduced carbon footprint
✅ Protection from rising energy costs
✅ Long system lifespan (25+ years)
✅ Increased energy independence
7. Is It Right for You?
If you own your property, have a suitable roof (ideally south-facing with minimal shading), and use electricity during the day, a solar PV system could be a great fit.
Commercial buildings, schools, farms, and community centres can benefit even more due to larger scale and higher daytime usage.
Final Thoughts: A solar PV system is a clean, efficient way to take control of your energy. It might seem technical at first, but once you understand the basics, it’s clear why so many homes and businesses across the UK are making the switch.
Got Questions or Ready to Start? At Genfit, we make solar simple. Whether you want a quick chat or a detailed quote, our team is here to help. Just get in touch — we’ll guide you through it, no jargon, no pressure.
Schools across the UK are under pressure to reduce costs, cut carbon emissions, and lead by example when it comes to sustainability. More than ever, solar PV is emerging as a practical and impactful solution — and at Genfit, we’re seeing a big rise in educational buildings making the switch to solar energy.
In this blog, we explore why solar for schools is growing in popularity, the benefits it brings, and how it works in practice.
1. Why Are Schools Going Solar?
Schools typically have large roof spaces and high daytime energy usage, which makes them ideal for solar PV. With rising energy bills and tighter budgets, solar can offer serious savings — plus it’s a visible commitment to sustainability that benefits students and staff alike.
2. The Key Benefits of Solar for Schools
✅ Lower Energy Bills
Solar panels help reduce dependency on the grid, lowering electricity costs year after year. Many schools can save thousands annually — money that can be reinvested into teaching, facilities, or student support.
✅ Reduce Carbon Emissions
Solar power is clean and renewable. Installing panels helps schools meet environmental targets and become more eco-conscious institutions.
✅ Educational Value
A solar installation can become a real-life teaching tool. Pupils can learn about energy, climate change, and sustainability in a hands-on way — especially if the school uses live performance data in the classroom.
✅ Long-Term Value
Once installed, solar panels typically last 25+ years and require very little maintenance. Schools can benefit from long-term savings and improved energy resilience.
3. Funding Solar in the Education Sector
While some schools fund solar installations outright, others work with community energy groups, councils, or apply for grants. Genfit has worked with several schools and trusts who’ve secured funding through innovative routes, helping them go solar with minimal upfront costs.
4. Real Examples: Solar in Action
At Genfit, we’ve completed installations at primary and secondary schools across the UK — from newly built campuses to historic schools retrofitting solar for the first time.
In one project, we installed a solar PV system on a school still under construction, helping it open as a future-ready, low-carbon building from day one. In another, a community energy partnership made it possible for a local school to generate clean energy and lower its carbon footprint without using its own budget.
5. Getting Started: Is Solar Right for Your School?
If your school or trust is exploring energy efficiency, solar is worth serious consideration. Our team can provide a free feasibility assessment to help you understand:
Roof suitability
Estimated annual savings
CO₂ reductions
