Solar PV electricity generation
Photovoltaic (PV) produce electricity from light. It is less efficient than wind turbines, both in payback time financially, and in the time it takes to ‘pay back’ the energy used in their construction.
Solar PV is very reliable and not as controversial as wind turbines
Solar PV benefits from the same Government Feed in Tariffs (FITS) scheme as wind generation.
A 4KW (peak) system of about 22 panels should produce around 3600 Units of electricity a year.
For generating this electricity the electricity company pays 43.3p per unit; £1558 per year.
To save installing a new meter the electricity company assumes that half of the electricity generated goes into the grid and pays 3p a Unit; £54 per year.
The above figures are not affected if the School and Play Group use the electricity. If they could use all of it, they would save on their electricity bills. If they pay 11p a unit, and could use all the electricity, it would save them £396 a year.
The above scheme is index linked and guaranteed for 25 years
1. The Solar PV offer is dependent on a successful wind turbine project for funding.
2. If OtleyGreen had to go for shares in the turbine project we might want a contribution from the Solar PV project to help repay shareholders.
3. The school roof might not be strong enough for Solar PV panels.
4. The slope and orientation of the roof might reduce the amount of electricity produced.
