The possibilities of solar thermal in commercial and industrial use are amazing. Hotel resorts and whole production lines could be converted to solar energy cost effectively, reliably, efficiently and environmentally friendly. Solar installations which produce process heat for paper and textile industries are common today and are profitable after a few years.
Heating and hot water supply for hotel resorts can be produced by solar
thermal with little effort on the roof top of the hotels. This can be prestigious,
media efficient and after a few years it will have paid off and the heating
energy will be for free.
