How much energy is that "0.5kWh" daily energy production number in line eight?
--Boot Hill
I appreciate the statistics - including the formatted table, which I plan to shamelessly steal from you to add to my own collection of useless energy facts - but I question the HORIZONTAL orientation. Why would it not be angled at the latitude value? You have a number for solar angle loss, that probably includes the average of 13.4% loss from this avoidable pointing error.
My solar water heating panels are appropriately angled - it is a trivial task, and allows rain to wash the dust off, as well.
The film can convert up to 30 per cent of the sun's power into usable, electrical energy. Today's best plastic solar cells capture only about six per cent.
Sargent and other researchers combined specially-designed minute particles called quantum dots, three to four nanometres across, with a polymer to make a plastic that can detect energy in the infrared.
Infrared light is not visible to the naked eye but it is what most remote controls emit, in small amounts, to control devices such as TVs and DVD players.Link
