Has anybody any experience with using solar panels for electricity in a normal house?

I use them for heating hot water and it works very well. You can try this company for more technical advice. www.saveenergyasia.com

Thanks for the tip, but I was thinking about trying to power the whole house!

As long as you don't need air con then i think its possible but if you live in Bangkok is it possible to live without air con?

I'm not in Bangkok!
