[hackerspaces] Raspberry Pi - $25 ARM based PC

[john arclight]

We've done several solar projects. You need to multiply the wattage of your
loads by the number of hours each is expected to be on.

For the panels, figure on 2-5 sun hours per day, depending on location and
climate. So a 40w kiosk open 8 hours per day would probably need in the
neighborhood of 100-160w in panels with a good 4 sun-hours daily. This is
doable on a budget.
