Solar collectors can convert solar energy into thermal energy. Solar collectors convert radiation into thermal energy. The absorption surface transforms the incident solar radiation into heat and transfers it to a heat-conducting substance.
A well designed solar system can save a huge part of the costs which are necessary for household. Cost savings associated with the production of hot domestic waterare 55-75% depending on the availability of sunlight. Cost savings associated with heating are 25-40%. In the summer solar system produce enought energy for domestic hot water and rest of solar increases can be used for heating water in pools.
Solar collectors are generally divided into two groups:
- flat solar collectors
- tubular solar collectors
While flat solar collectors are mostly used for seasonal water heating, tube solar collectors, capable of achieving higher performance, can be used in a long term as a source of low-temperature heating method. Both collectors can help achieve a significant energy saving.
