Solar collector systems are advantageous to build in facilities where hot water is consumed regularly throughout the year, such as private homes. Even more advantageous if the consumption of hot water is seasonal in summer, such as in cottages, guest houses and hotels.
The solar system in Latvia has been operating productively for 6-7 months, from April to October. Between November and February, when there is not enough heat produced by the sun, it must be taken from the existing heat supply system.
The system of professionally designed solar collectors switches to another energy source automatically.
