My personal feeling on Solar that it will never pay a massive part in grid electricity, but my recent experiments with site specific use have certainly proved cost effective and reasonably efficient for low voltage use, even in the UK.

To me it seems a little bit daft that in such hot countries that more people are not encouraged to fit solar on their roof as part of their energy consumption, what ever the efficiency of the panels is. Once installed the panels could be swapped in 10-20 years time and they have run their life.

The UK has had an interesting solar scheme backed by government for the past few years. My neighbour has had "free" solar panels installed, and even in our dodgy climate has seen his electricity bill fall quite a bit.

Cheers
