More information about solar power

Photovoltaic (PV) panels convert

sunlight into electricity in the form of direct current. Recent advances in

solar technology mean it is available to use in the leisure market at an

affordable price and can provide usable power.

As the energy produced by the PV

array often does not correspond to the temporary energy demand of the consumer

it may be necessary to store the energy in batteries for use when required.

Below is a diagram of the most

common type cell, the Crystalline Silicon solar cell. It is composed of two

differing silicon layers. The top layer is negatively charged and the bottom

layer is positively charged. The sunlight causes electrons to be set free and

move between the two layers generating a small electric charge. If the circuit

is closed then electricity can flow.
