Q. What does it all cost?
A. The installation costs for a worthwhile system are around £22k. Anything smaller than that isn’t really worth the effort. There’s enough roof space to install a larger system with more panels. This would cost around £35k.
The research and startup costs have been covered by a grant from the Rural Communities Energy Fund This means all the future grants and donations we receive will go towards actually buying the system.
Q. Do we have a full life cycle analysis of environmental benefits/disadvantages including manufacture costs?
A. See here for a basic review of these issues. Overall, producing energy from solar PV has less environmental impact than producing the same amount of energy from fossil fuels. Currently solar PV systems have an expected life-span of 20 – 25 years.
