Active Solar Heating
Active Solar technologies are employed to convert solar energy into usable heat, cause air movement for ventilation or cooking or store heat for future use. Unlike Passive Solar, Active Solar uses electrical or mechanical equipment such as pumps and fans to increase the usable heat. The most common use of active solar in Europe is Solar water heating. It is estimated that a correctly sized solar water heating system can provide for up to 60% of your water heating needs. Indeed, studies have shown that one square metre on your roof receives the equivalent of more than 100 litres of oil in free solar energy per year. Solar panels, generally located on a south-facing roof, transform solar radiation into heat which is stored in a large hot water cylinder for whenever you need it.
