We use the words thermal solar power to describe any system designed to convert solar radiation into thermal energy. It is one of the major players in the solar power market and has huge untapped potentials.
The field of thermal solar power is large, and ranges from a simple system to heat your water tank, up to full fledged steam power facilities in use today. With a little thought, one can imagine a wide variety of applications for thermal solar technologies.
For small scale applications, thermal solar power is used in the home. The heat is used to maintain hot water tanks, or is stored in the floors or walls of our buildings.
There are other good uses for thermal solar power which we expect to increase in years to come. One is pebble bed heat exchangers, which act as a thermal storage bank for converted heat. This gives us some system capacity and operating flexibility.
Applications for pebble bed heat exchangers include radiant heating in and around our homes. They can be integrated into greenhouses, saunas, or even in your family rooms. Pebble bed heat exchangers are made from natural materials, and can be an attractive feature in any home.
The typical operating temperature for most thermal solar power systems will be between 100F and 180F. In good solar climates these temperatures can be easily achieved with popular off the shelf equipment. With more specialized equipment we can go in excess of 250F, and with high performance industrial equipment over 700 degrees is possible. These high performance systems are usually for making steam, but incorporating them into other processes is also possible.
At the core of any thermal solar power system will be the solar collector. This is the component directly responsible for generating your heat. The most common design is the flat plate absorber, which often have selective surfaces for high absorptivity and low emissivity of solar radiation. Other designs include evacuated tube collectors, and parabolic trough concentrating receivers.
The circulating fluid flows through the solar collector to distribute the heat through your system. It should be selected based on the peak operating temperatures and equipment compatibility. Typical fluids are glycol, oil, and water. A low flow pumping system will be needed that is agreeable with your operating conditions.
Thermal solar power is a good first step for anyone getting involved with solar energy, and especially those with good amounts of Sun. The simplicity, potential savings, and environmental benefits make them an easy decision for those retrofitting or building a new home.
We believe thermal solar power to be a steadily growing market into the future, due to a growing awareness of energy conservation and reverting back to our natural ways. Thermal solar power is one good way to do this. The Sun is free, and we receive its energy each and every day. Solar hot water, home heating, and pebble bed heat transfer systems are simple to incorporate and easy to use. We believe their popularity will gain in years to come.
