Installation of Solar Panels with photovoltaic cells
Photovoltaic cells are a part of solar panels. Solar panels have a lot of photovoltaic cells lined upon them to convert sunlight into voltage. The solar panels use the voltage generated by the photovoltaic cells and convert it into power.
The photo (top left) shows the 18 panels in the process of being fitted. Underneath the Panels are the "Roof Trays" - these provide waterproofing to the roof and the Panels are laid on top to allow the Panels to be integrated into the pantiles. The Panels contain many "PV" cells that capture the energy from the Solar Panels.
The energy generated in each individual cell is then distributed on a priority basis - recent technology provides a system that communicates with the power supply to, for example, send the power to the Hot Water, Air Source Heat Pump, Domestic use (fridges etc) and then to the "Grid". Anything left can potentially be stored in an Electric Vehicle (EV) battery or the 20kwh batteries as part of this system.
Before installing Solar Panels there is some paperwork to do. The G99 application form is used to "ask for permission" from the local Distribution Network Operator or DNO (In Yorkshire for example that is Northern Powergrid). You will need to provide a Site address (address where you want your connection) and a Site location plan clearly showing your site boundary and preferred meter position.
In addition to Site information, details of the system you wish to have installed - these can be provided by your preferred installer.
As can be seen on the photo (bottom left) a bank of 5 Velux Windows have also been installed on the opposite side of the roof - these provide light, fresh air and as they are triple glazed help towards heat efficiency.
