New book - 'Building a Better World in Your Backyard' - on Kickstarter (sponsored friend)
Often Solar powered electrical generation relies on heat engines and photovoltaics. Solar energy's uses are limited by human ingenuity, and the finite resourced to build the sys. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, daylighting, solar hot water, solar cooking, and high temperature process heat for industrial purposes.To harvest the solar energy, the most common way is to use solar panels.
Solar technologies are characterized as either passive solar or active solar, depending on the way the energy is captured, converted and distributed. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy. Passive solar techniques include orienting a building to the suns seasonal orientation, selecting materials with favorable thermal mass, which will capture and radiate solar energy, light dispersing properties that will disperse light energy, or designing spaces that naturally circulate solar heated air.
