Recently I have been working on solar roof system. It's BIPV that contains solar cells embedded on synthetic ceramic slate tile. Both on-the-grid and off-grid are accepted, some additional accessories are required. Frankly, I'm deeply impressed by this kind of solar roof architecture. It's kind of upgrade from roof with solar panels. If you are interested, visit my website for more info, www.anroof.com
the latest solar power application which I'm interested.
