Solar Photovoltaic

Photovoltaic systems use cells to convert sunlight into electricity. The PV cell consists of one or two layers of a semi conducting material, usually silicon. When light shines on the cell it creates an electric field across the layers causing electricity to flow. The greater the intensity of the light, the greater the flow of electricity.

PV cells are referred to in terms of the amount of energy they generate in full sunlight, know as kilowatt peak or kWp.

The benefits

PV systems are static, silent, non-obtrusive and produce no greenhouse gases. In addition every KWh generated locally and not therefore taken from the National Grid saves 568kg of CO2 emissions.

Is it suitable for my building?

You can use PV systems for a building with a roof or wall that faces within 90 degrees of south, as long as no other buildings or large trees overshadow it. If the roof surface is in shadow for parts of the day, the output of the system decreases.

ESEA Ltd are PV solar panel suppliers based in Peterborough and install a range of solar photovoltaic panels throughout the UK to both commercial and domestic properties.
