Solar PV Installations


Solar PV

Protect your future

Installing a Photovoltaic (PV) System to your roof or garage can help reduce your future bills by producing your own renewable electricity from the sun. You can sell the electricity you don’t use and create a tax free, index linked income. The PV systems can be easily incorporated into your existing electrical installation to feed your appliances and lighting. They can also be used to supply heating systems, reducing your bills even further.

Dont rent your roof to get free panels. Install your own system and claim all the benefits of free and sustainable electricity.


Free and Sustainable Electricity

Being green really does pay

You can be paid for the energy you produce and see a return better than any ISA with a government backed scheme. The FITs scheme guarantees a minimum payment for all electricity generated by the system (generation tariff), as well as an additional payment for the electricity exported to the grid (export tariff). The payments you are eligible to receive vary depending on system size and when it is installed. The payments are index linked and guaranteed for 25 years, so you can reduce your electricity bill and earn an income.

Unlike PV systems that are fitted for free, installing your own system ensures you recieve all the money that your system produces as well as having free and sustainable electricity. To show you the kind of money you could receive from your PV system installed with Solarcell, we have provided examples of the cost benefit analysis for two installations of a 4kW PV system. These can be viewed on the Quotation page

For your own peace of mind and for  further information on the government scheme, latest news and things to look out for before choosing your installer, visit these reliable sites such as,, (department of energy climate change) and the MCS accreditors for installers.


How does a PV system work?

No need for direct sunshine

Solar electricity systems capture the sun’s energy using Photovoltaic (PV) cells. The cells convert the sunlight into electricity which can be used to run household appliances and lighting.

PV cells don’t need direct sunlight to work, so you can still generate electricity on a cloudy day. The amount of energy produced depends on the system’s orientation, shading and how sunny your roof or site is, as well as the size of the system that you have installed. Check your roof on Google Earth for orientation.

How is it measured?

Solar electricity systems are given a rating in kilowatts peak (kWp). The total amount of electricity the system actually generates in a year is measured in kilowatt hours (kWh).

A typical domestic system is between 1.5 to 4kWp. Each kWp should generate around 800 to 850kWh per year if unshaded and perfectly south facing with a tilt of around 30-50°.  The solar PV supply feeds into your existing system and the electricity generated is either used in your house or is exported to the grid, depending on how much you are using at the time. Solarcell installs one of the highest energy yielding PV panels to ensure you get top quality product and the best return on your investment. With the UK Government’s Feed-in Tariffs (FITs) scheme, you can get paid for the electricity you generate and connection to the local grid is not as complicated as you might expect.

Types of installation

A domestic Solar PV array comprises of PV modules (panels) which can be ‘roof-mounted’, ‘built-in’ or ‘ground mounted’.

‘Roof-mounted’ PV is the most commonly used Solar PV installation and the most cost effective used on existing homes. These systems are mounted onto existing roofs using brackets that are then attached to rafters, leaving the roof in its original state underneath the Solar PV array.

‘Built-in’ installations are particularly popular with new-builds, extensions or when home owners are re-tiling their roofs. It’s a cost effective alternative to a full tile replacement and can also appeal to customers based on their aesthetics alone.

‘Ground mounted’ systems can be installed in fields and larger gardens, using secured framework.

Solar PV installations don’t have to just supply electricity for lights and appliances they can also be incorporated into an electrical heating system reducing your bills further.


From 1st of April 2012 an energy performance certificate (EPC) of grade D or above will be required for you to qualify for the tariff of 21p. Solarcell can provide the EPC as part of the assessment and installation process at no extra cost.
