Eco toys & gifts for kids, from simple beads that change colour in the sunlight to temperature driven Stirling engines. Each eco toy is operated either by solar power or by other types of green energy.

Most cost effective quote. Install is of high quality and they were good to work with. I recommend them if you are considering putting solar at your home.
