Proper maintenance and protection of solar collectors is important for preserving the system’s functionality. In the event of an absence for a long period, especially during the summer months, covering the solar collectors is recommended. When they are not covered, there is a risk of water accumulation in the boiler, which can cause overheating and require bleeding of the closed circuit as well as replenishment of the thermal fluid upon return. If the routine maintenance has not been performed, there is a possibility that the boiler safety valves may not activate, with the risk of damage to the boiler.

In addition, during the winter months, the use of a cover is considered necessary in cases of low temperatures to protect the system.
