ensuring your system is as efficient as possible.
If you are entirely new to photovoltaic electricity and you don't have a copy of The Solar Electricity Handbook, you can buy one today
either as a paperback book or as an eBook. It is available all around the world: find a bookshop near you.
Alternatively, you may find it useful to read the first few chapters of the Solar Electricity Handbook free from our
