Active Solar Panels

Active solar energy systems use the same principles as passive systems except that they use a fluid such as water to absorb the heat.

Active solar panels.

An active solar energy system may be used for any of the following. The most common example of course is the thousands of rooftop solar panels in neighborhoods across the country taking sunlight and processing it into electricity. An active solar energy system is a system that uses solar devices which are thermally isolated from living space or any other area where the energy is used to provide for the collection storage or distribution of solar energy. Active solar heating systems use solar energy to heat a fluid either liquid or air and then transfer the solar heat directly to the interior space or to a storage system for later use.

Active solar on the other hand is any technology that processes that sunlight or its properties ie its heat into something else. Photovoltaic solar energy is clearly an active solar energy system. A solar collector positioned on the roofs of buildings heats the fluid and then pumps it through a system of pipes to heat the whole building. They offer a return well above the long term average return from both the share market and also property investment.

Solar panels have fallen in price by more than 80 in the last ten years.
