According to the SEIA/GTM Research U. Solar Market Insight 2013 report there were 930 MW of solar PV installed in the second quarter of which means there is now MW of solar energy in the U. (What's in a megawatt?) What does all that solar add up to?
Solar-powered window blinds, soak up sun by day, illuminate the room at night. Interesting concept for emergency power outages. (I poked around looking for these and didn't find them available. Great concept though )
