How Solar PV Works

How Is Electricity Generated With Solar PV Panels?

The photovoltaic cells, which are vital to the Solar PV are devices capable of turning light into an electric current, and these are the part of the panel which turn sunlight into the electrical energy. In order to protect these panels from damage or moisture though, they are manufactured into PV Modules to ensure their longevity and functionality remains.

How Do The Solar Panels Get Installed?

For a detailed outline of this, please visit the Installation Guide which can be read here.

How Can My Solar PV Electricity Be Used, and How Is It Spread Through The Home?

The Solar PV's make a kind of electricity called DC (Direct Current), which is not suitable for use in homes, and therefore has to be converted into a type of electricity called AC (Alternating Current). An 'inverter' is used to turn the electricity into the required format, and how this works is that it analyses the electricity coming into it from the National Grid, and converts the DC from the Solar PV into the same usable product. A wire runs from the AC output to the fuse box, and onto a miniature circuit breaker (MCB). Where the inverter is located in the house depends entirely on the results of the free site survey conducted.

After the inverter has converted the DC Current into usable AC energy, this is then used to power your home's electrical appliances. Any you don't use gets sent back and sold to the National Grid for use in other homes.

How do clouds affect generation?

Even if a day seems overcast and cloudy, this should not affect power production as the panel works off light as opposed to heat. In the brighter summer months the panels tend to produce more, and the amount of energy given off changes seasonally, but this is not due to weather changes.

How do I know if a Solar PV system is suitable for my home?

Regardless of whether a building is in an urban or rural location, Solar PV paneling is available for use on any building which has enough exposure to light. Usually the panels are mounted on an angled roof, but it is also possible to mount them on a flat roof or the ground. More information is available in our section 'Solar PV and the Home.'

How Does Payment Work For My Excess Solar PV Electricity?

Due to the fact that your electricity bill will be lessened every year, your Solar PV will save you money, but in addition, it can also earn you money back. At least 41.3p can be earned for every unit of electricity with a regular 4kWp domestic system. More information on the financial rewards of Solar power can be found in the 'Investing in Solar PV' part of our website.

Getting paid for your electricity is extremely simple. All that needs to be done by you is to inform the supplier of your power that you have invested in some Solar PV equipment and they will send some forms your way. Our trained installers can assist you in the entire application procedure.

The National Grid are informed about this by the distribution network officer, who will be told about your solar system by us.

It takes on average four years for the electricity produced to become of more value than the carbon cost to make the Solar PV Panelling.
