Solar PV

Green Heat Wales have over fifteen years experience in the renewable energy sector and offer a bespoke service to each and every client.  We have a wide range of quality products and never use cheap imports as a rule.  Our team of specialists are fully trained installers, each having a passion in reducing your carbon footprint and offering you quality of service.  Our feedback from clients is exemplary and we offer our expertise and knowledge in regards to any technical queries they may have about any of our products, such as Solar PV.

We design and install Solar Photovoltaic (PV) systems to suit both commercial and industrial sectors for new build, refurbishment and existing buildings. With our combined knowledge of construction and PV systems, we can provide you with a building integrated, roof or ground mounted PV system. We will manage the process from the design & consultation stage right through to installation and performance monitoring.

Please Call us to arrange a no obligation survey and price for supply and install.

Solar photovoltaics (PV), also known as solar panel electricity systems, use photovoltaic cells to capture the sun’s energy.  They don’t need direct sunlight to work because they can still generate electricity even if it is a cloudy day.  Sunlight is converted into electricity via the cells and this can then be used to light your home and run your domestic appliances.

PV cells are created by using layers of semi-conducting materials, typically silicon.  When sunlight shines onto the cells it forms an electric field across the layers.  The more sunlight that hits the cells the more electricity is produced.  These cells are then grouped together into panels or modules and are placed onto your roof.  PV cells can be made in various shapes and sizes and the power that they generate is measured into kilowatts peak or kWp.  They can be made into panels on your roof or you can opt for solar tiles.

Solar tiles replace your existing roof tiles but they cost twice as much as the panel system.  They also don’t work as effectively as the panel systems and most installers will only advise to have this form fitted if planning requires it or for aesthetic reasons.

Costs of installing the systems have fallen greatly in the last year.  Also they require very little maintenance once they are installed.  The most important thing to do is to make sure that nothing overshadows them, such as trees.  They need to be kept quite clean but if they are tilted at 15 degrees or more the rain will do this job for you.  The risk of debris on the panels only really affects panels that are ground mounted.

EPC of ‘D’ or above

You will need an Energy Performance Certificate of ‘D’ or above to obtain the higher rate of FiT. We will arrange this for you if you do not have one. Properties with an EPC level below ‘D’ are still eligible for the lower FiT rate of 6.61p.

Feed-in Tariff rates

  • 4kWp 13.39p
  • 4kWp – 10kWp 13.50p
  • 10kWp – 50kWp 12.57p
  • 50kWp – 150kWp 10.71p
  • 150kWp – 250kWp 10.25p
  • 250kWp 6.61p

The panels should last 25 years or more but your inverter may need replacing before this.  Solar panel systems are great because solar electricity is green, renewable energy.  Your system, once installed, can save over a tonne of carbon dioxide per year, which is over 30 tonnes over the systems lifetime.

There are many benefits to having a solar PV system installed in your home, they are as follows:

  • They will help lower your electricity bills because sunlight is free.
  • You can get paid for the electricity you produce through the government’s Feed-In Tariff.
  • You can sell your electricity back to the Grid if you produce more than you need.
  • You will be reducing your carbon footprint.
