Active and passive solar energy

Active solar energy technologies change the energy of the sun into usable light and heat. An active solar system has the capacity to store energy for later use by storing it in batteries.

An active solar energy system uses electrical or automatic equipment or processes to increase the usable heat in a system.

Active solar systems have solar panels, collectors, batteries, voltage controllers and other system components including wiring so that the heat energy of the sun is collected, transferred and converted from DC to AC current that is compatible with the local electric grid.

In the start the use of solar energy was limited to activities where the natural power of the sun could be utilized without any aid of other technologies or materials.

In spirit the power of the sun was used for natural heat and its capability to dry people or other items like clothing, foods and environmentally friendly furniture such as berries. We call this type of solar power passive solar.

Passive solar energy is the most typical home solar power currently in use. Many homes are designed for passive UK solar. With the proper use of glazing materials (lots of windows) and a southern exposure for your home a lot of heat can be captured.

Solar energy is the best form of alternative energy that is both renewable and sustainable. The abundant light and energy that our planet receives from the sun every year can actually supply sufficient amounts of energy for millions or even billions of years.

A very small fraction of the total solar energy collected on earth is being used for similar purposes.
