Currently when we boil a kettle, use a computer, or watch TV, if the electricity we use is generated from fossil fuels, we add further emissions to the atmosphere. The meaning of photovoltaic is electricity from light. This is not the customary solar thermal technology used for heating and hot water. Photovoltaic technology uses daylight to power ordinary electrical appliances. Daylight is enough to generate electricity so sunshine is not necessarily needed.
Businesses also use solar technology.
A popular supermarket has for example constructed a service station in North Greenwich as part of their environmentally friendly site. They decided to fix up a solar PV system on the canopy of the petrol station, its supports the ethos of their Eco store located on the same site. Environmentally harmless technologies such as passive heating, wind power and skilled use of natural lighting are used by the Eco store combined well with the use of solar PV to significantly reduce carbon emissions. The installation powers the lighting and petrol pumps, also provides free electricity to an on-site plug in electric car recharge port. Service Station, North Greenwich Technical Description 90 PV modules rated at 75W each under standard test conditions were mounted on the roof and wired together in 10 parallel rows.
