A solar cell or rather a photovoltaic cell takes the light from the sun and converts it into power. Solar thermal systems take the heat from the sun and use that to heat water and homes. However in the UK we have unpredictable weather and photovoltaic power is more commonly available.
The photovoltaic panels use are considered by many well suited to use on property and equal use on land base areas, a good site is South facing and this will provide almost continued sun or good ultra violet light as natural light most of the day light hours.
With the use of solar power, the customer must firstly look very carefully at the full Investment cost and compare it with the years of use to a payback cost, this can be different on each situation but the average investment would be based over a 20 – 25 years with a payback at around the 10-15 year mark. You then have to obtain Planning Permission prior to any installation for commercial use, this could be an advantage if you elect to install say a PV 4-10kW (retrofit) on existing building or a larger PV 100Kw-5MW on a large open plan land site where you would be well able to enter into a sell back system known as (FIT) by selling back your extra required energy to the nation grid at a profit. |
