Solar Fan by JD Solar

A solar fan is a mechanical fan powered by solar panels. The solar panels are either mounted on the device or are installed independently. Solar fans mostly do not require secondary power sources other than solar power, as most of them are used for cooling purposes during day time. Some types are also used for heating purposes. It runs the fastest when it is the hottest outside providing savings on air conditioning costs. Attic heat is caused by the sun baking down on the roof surface. This sunlight causes the roofing material to heat up, thus transferring the heat into the attic via thermal transfer. The buildup of heat is generally dissipated by normal convection, i.e.: as the air is heated it expands and rises, flowing out of the attic through vents placed at or near the peak, while fresh air is pulled into the attic from intake vents that are generally in the eave (soffit) area. However, most roof vents are inadequate at expelling the heat and require the use of a powered vent fan to remove heat effectively. A solar powered attic fan is an effective way to remove attic heat using only the power of the sun to run the fan. We are dealing in Chennai Tamilnadu only.
