Across the UK, and especially in rural counties like Powys, many homeowners are asking the same question: is it worth investing in solar PV? With the rising cost of electricity and increased pressure on households to make homes more energy efficient, renewable energy solutions have never been more relevant.
Solar PV systems allow you to generate your own clean electricity, reduce your energy bills, and even earn money by selling surplus power back to the grid. For households in Powys, where properties often benefit from good roof space and a strong community commitment to greener living, solar PV can be a very practical choice.
In this article, we’ll take you through everything you need to know about solar PV in Powys, including how it works, its benefits, potential drawbacks, funding options like ECO4, and how Green Homes Group can support you in taking the next step.
Solar PV (photovoltaic) technology works by converting daylight into electricity using solar panels made from layers of semiconductor material. When sunlight hits the panels, it creates an electric field that generates direct current (DC). This is then passed through an inverter, which converts it into alternating current (AC) — the type of electricity used to power your home.
A standard system will usually include:
Unlike solar thermal panels, which only provide hot water, solar PV produces electricity that can run anything in your home — from lights and washing machines to electric vehicles. Even on cloudy days, panels generate energy because they rely on daylight rather than direct sunshine.
Powys has many features that make it an excellent candidate for solar energy adoption.
Electricity prices have risen sharply, putting pressure on household budgets. Solar PV reduces the amount of power you need to buy from the grid. A typical 4kW system can generate around 3,400 kWh of electricity per year — covering a significant portion of an average household’s demand. For families in Powys, this can translate to hundreds of pounds in annual savings.
Solar PV is a renewable energy source with no direct emissions. By installing panels, households in Powys can cut their carbon footprint and make a tangible difference in the fight against climate change. This is particularly appealing for those who want to live more sustainably and reduce their reliance on fossil fuels.
Energy independence is becoming increasingly important. With solar PV and battery storage, you can generate and store power during the day for use in the evening. This reduces vulnerability to price hikes and grid instability. In rural areas of Powys, this can provide peace of mind during power cuts or supply disruptions.
Homes with renewable technologies are often more attractive to buyers. A solar PV system can increase the value of your home by thousands of pounds. Prospective buyers are more likely to see your property as modern, efficient, and cost-saving, which can give you a competitive edge in the housing market.
The ECO4 scheme (Energy Company Obligation phase 4) is the government’s flagship energy efficiency programme. It runs until 2026 and targets low-income and vulnerable households. If you qualify, ECO4 can provide significant funding towards measures like solar PV, insulation, and heating upgrades.
Eligibility is usually based on household income, benefits status, or your home’s Energy Performance Certificate (EPC) rating. Many homes in Powys qualify due to their age, condition, or heating systems. Through ECO4, some households could get solar PV at little or no upfront cost.
Another benefit of solar PV is the ability to earn money through the Smart Export Guarantee. If your system generates more electricity than you use, you can sell the surplus back to the grid. This provides a steady income stream and reduces the payback period of your investment.
Powys County Council and various community groups have shown strong support for renewable energy. While local schemes vary, they may offer advice, pilot projects, or small-scale grants. It’s always worth checking what additional help is available locally.
The cost of installing solar PV has fallen significantly in the last decade, making it more affordable than ever.
Many people assume Wales is too cloudy for solar panels to be effective. In reality, solar PV works well in diffuse light and continues to generate energy even on overcast days.
The initial outlay can be daunting, but ECO4 support, SEG payments, and bill reductions all help make solar PV more affordable. For eligible households, ECO4 may cover much of the cost.
Not every roof is perfect, but installers can often find solutions. South-facing roofs are best, but east- or west-facing roofs can still generate significant power. In conservation areas or listed buildings, planning permission may be required.
In most cases, solar PV is classed as “permitted development”, meaning no planning permission is needed. Exceptions include listed buildings, flats, or properties in certain conservation zones.
Your roof should ideally have a good amount of unshaded space. Trees, chimneys, or nearby buildings can reduce output, but this can often be managed with careful panel placement.
If your household uses more electricity during the day, you’ll benefit most from solar PV. However, pairing the system with a battery allows evening and night-time use, increasing efficiency.
Battery storage allows you to store excess electricity during the day and use it later. This maximises savings and can even help protect against blackouts. Many homeowners in Powys are now choosing to add a battery when installing solar PV.
ECO4 is one of the most powerful tools available to help households in Powys adopt solar PV. It is funded by large energy companies and targets homes that are expensive to heat or occupied by vulnerable residents.
The process usually involves:
For many households, this scheme makes the difference between solar PV being unaffordable and solar PV becoming a reality.
At Green Homes Group, our role is to guide you through the process of improving your home’s energy efficiency.
Our goal is to make renewable energy and government support accessible to as many households as possible.
Yes, for many households, it is. Solar PV offers lower bills, reduced emissions, and greater energy independence. When combined with government support such as ECO4, the financial case becomes even stronger.
For Powys residents, solar PV represents an opportunity to take control of rising energy costs while also helping the environment. The next step is simple — arrange a free home survey with Green Homes Group and discover exactly what’s possible for your home.
Yes. Panels generate electricity from daylight, not just direct sunshine.
Most panels last 25–30 years and carry performance warranties of at least 20 years.
Yes. It can complement heat pumps, smart controls, and insulation upgrades.
The system usually stays with the property, increasing its value and appeal to buyers.
