Reducing Electricity Bills by Using Solar Thermal Energy

Solar thermal energy is an alternative energy that offers many benefits for human life. As the decreasing of the finite fuels, many people are trying to develop renewable sources of power. Solar energy is the best invention that can provide electricity by harnessing the solar. In the recent time, solar thermal energy gains its popularity in most of people in the world.

Solar Water Heaters

Solar thermal energy is considered as one of most economical and the simplest ways to utilize solar energy. It can be used for heating water, heating water in the swimming pool and space heating applications. This can be done in individual homes by using the sun’s energy collected on solar panels from where the warmth is transferred to water flowing in copper tubes.

Solar thermal energy system assists to outfit electric water heating system or an existing gas in colder areas. It is believed can reduce the costs. While in warmer or not too cold area, solar energy system can be used directly for bathing or in swimming pools. By doing this, you can reduce the costs by hundred percent.

There are two essential solar systems for hot water - passive and active. The passive solar thermal energy system is based on energy which is drawn from the sun and then transferred to warmth water for domestic use. This type of system is only possible to use in warmer climates. The active solar system is appropriate for colder areas. This system utilizes a pump to push the water through the solar collector and into the home.

The active solar system can be an open loop where the water is directly heated by the solar collector. Furthermore, it also can be a closed loop system where antifreeze or glycol mixture is heated before transferring its heat to the water by a heat exchanger. The drain back system is a popular closed loop active system. In this system the freeze proof design drains water back into a small holding tank when freezing temperatures occur.

For colder climates, the closed loop system is greatest appropriate. This solar thermal energy system utilizes heat transfer liquid, a solar collector, heat exchanger, a storage tank, differential temperature controllers, and. circulating pump.

Solar collector captures the sun’s energy to transfer heat to an anti-freezing liquid. The heated fluid is pumped into the home. It then transferred to the domestic water supply which is stored in a tank for later purposes.

As describe above, solar thermal energy brings lots of benefit for people and this earth. If you are still using electric power, it is the time to shift to solar thermal energy. If you need more information, please explore links on this Solar Energy Secret site.
