What are the advantages of solar thermal water heating systems at a personal level?

Most importantly: The energy of the sun is endless, sufficient and free of charge. Using solar water heating technology makes you independent of the rapidly increasing fossil fuel prices. It saves customers energy, money, is clean and safe and it is a long-living technology with life cycles of 25 years and more.
In the summer your system can provide 100 % of your hot water demand for showering and bathing. To make sure that you do not run out of hot water, there is always a backup system for the times the solar system cannot provide all your needs. In sunny regions such as Southern Europe and Northern Africa solar water heaters can provide almost 100 % of the hot water demand of a family.
