SunStream Photovoltaic Panels
PV panels use the energy from the sun to create electricity, they only require daylight to produce electricity as they operate in both direct sunlight and cloudy conditions.
How do they work:-
A solar PV system comprises of a number of individual PV Cells that are connected together to form a module, a number of modules are then connected depending on the size of the system to form an array.
Each cell consists of either one or two layers of semi-conduction material usually silicon, when light its theses cells an electric field is created across the layers thus causing electricity to flow, the higher the intensity of the light the higher the electricity flow.
The amount of electricity generated thus depends on the number of cells in an array and the light intensity.
System requirements:-
Apart from the PV panels a system will require an inverter to convert the electricity from direct current (DC) to alternating current (AC), as is delivered via the mains into your homes.
The system is then connected to the mains, with an additional meter which registers the amount of electricity generated. Unused power can be sold back to the grid.
