They often use a rooftop collector to concentrate solar energy, a liquid medium to absorb and transfer heat, and various pumps and simple controllers move the heated liquid.\u003cbr\u003e\u003cbr\u003eThese systems have remarkable utility, even in many relatively cool regions. Some of the tests cited were conducted at Air Force installations in Washington State!\u003cbr\u003e\u003cbr\u003eUseful to anyone looking to build a low cost DIY solar collection system, it includes typical installations and \"rules of thumb\".
