Best website for Solar energy kit for the DIY'er, clear information for determining components needed for customising your own setup. Very minor criticism is that there are few dimensions provided with the pictures. Overall great shopping experience.
One of the most helpful companies for photovoltaic and solar related products around. Very competitive too. Their deliveries are some of the quickest. I would not go past them.
Bimble Solar are worth a 10/10 any day of the week.
