                 GRID-CONNECTED SOLAR ELECTRIC SYSTEMS

Solar electric (Photovoltaic ( PV) ) systems produce electricity according to the amount of sunlight that falls on their surface, For this reason unshaded, preferably south-facing, surfaces are best. The pitched roofs of most houses in the UK are ideal. Flat roofs can be utilised by fitting a frame to hold the PV modules.

Output will be reduced by shade or non-optimal orientations or tilt angles.

 The  average annual electricity consumption of a household of 4 in the UK is 3500-4000 kWh per year (3.5 to 4 MWh/year)
A 1 kWp grid-connected PV system in the UK will produce about 700- 800 kWh of electricity per year and require about 8 m2 of roof area.
A 5 kWp grid-connected PV system in the UK will produce about 3500- 4000 kWh of electricity per year and require about 40 m2 of roof area.

Grid connection of a solar (photovoltaic) system MUST have local electricity company approval. The installers should be Clear Skies (government) registered and they should ensure the system is properly installed and with the required degree of protection.

When your PV system is connected to the grid it will produce electricity that will be used directly in your home. If the system is generating more power than needed by the home then the excess is sold back to the electricity company. If your system is not providing enough to meet the electrical energy demand in your house the utility provides the difference.

In effect, the grid acts as an energy storage system, which means the PV system does not need to include battery storage.

Note : there are costs associated with grid-connection and metering to and from the grid. The electricity companies do not pay a generous rate for electricity 'exported' from your PV system to the national grid. In fact, the cost of 'importing' (buying) units of electricity from these companies is usually a lot more than they will pay you for your renewable electricity. It is usually best to design your system so all power that is generated is consumed on site - and that a minimum of 'imported' / expensive electricity is bought from the electrical utility company.
