What is the best renewable energy system...
Solar PV panels convert daylight into electricity. They work from light (irradiance) and not just direct sunlight.
The PV panels are wired to an Inverter which converts the generated electricity from Direct Current (DC) into usable Alternating Current (AC) for use in your home.
The Inverter (AC) output is connected to the electrics in your home via your existing consumer unit. This in turn exports any surplus electricity back to the National Grid system.
At the heart of a solar PV system are photovoltaic cells; devices which convert light into an electric current. These photovoltaic cells are responsible for transforming the sun’s energy into electricity. These cells can be ‘housed’ in many ways but by far the most common is the PV Panel.
This is the piece of equipment that converts the electricity produced by the PV panels into the form of electricity that we use within domestic and commercial properties. The electricity that goes into the Inverter is in the form of direct current (DC) and the electricity that comes out is in the form of alternating current (AC).
The export meter records all the electricity produced by the PV panels in exactly the same way as the electricity meter within your property. The figures it records are then used by the householder to provide there electricity supplier with a reading with which they can use to calculate their Feed In Tariff's (FIT) payment amount.
