Water, sun and wind - the most affordable sources of energy. Solar heating systems are becoming popular in many countries around the world.
Solar water heaters can be active or passive types. If you want to heat your home with solar energy, you need to decide whether you want an active or a passive system. The active solar system uses an electric pump to circulate fluid through the collector. The passive solar system has no pump and relies on natural circulation. The amount of hot water a solar water heater produces depends on the type and size of the system
Passive Solar System
Passive solar heating represents an important strategy for displacing traditional energy sources in buildings. Methods of passively collecting energy include solar ovens and well-planned indoor heating techniques. All passive techniques use building elements such as floors, walls, windows, to control heat generated by solar radiation.
A commercial building can abate its electricity bill by using the total daylight of the surrounding sky. It will create a pleasant environment and reduce air-conditioning costs too because a considerable amount of heat is generated by the light bulbs or ballasts.
The need for air-conditioning in homes can be greatly reduced or even eliminated by using passive solar cooling.
Active Solar System
Active solar energy is the conversion of solar energy into usable heat via electrical. There are three types of applications that you can use in your home: Solar Water Heating, Solar Pool Heating, Solar Space Heating.
Whether you are interested in solar space heating or solar pool heating, active solar energy can help you take full advantage of solar heating.
