6 FAQs about [Use of solar power generation antifreeze device]

How to protect a solar system from freezing water?

How important is anti-freeze protection?

The anti-freeze protection system consumed annually from 7 to 13% of the heat generated by the collectors in the installation. Supporting the operation of the central heating system in the building during the winter season highly improved the efficiency of the solar collectors.

Are there devices that heat the installation components exposed to freezing water?

There are no devices that heat the installation components exposed to freezing of water, e.g., heating tapes. The operation of this system under real conditions was analysed for five years in a residential and retail building located near Kraków in Southern Poland.

How can a solar power system be adapted to a heat storage system?

In the literature, several solutions can be found: automatic control system equipped with an anti-freeze protection (AFP) function which, by switching on the solar pump, allows for the transfer of heat from the heat storage to the SC;

Is water without additives a good option for a solar system?

It is also worth noting that water without additives that reduce the freezing point is environmentally-friendly, unlike other substances used in solar systems. Traditional methods of producing propylene glycol are based on the processing of crude oil.

Can superhydrophobic glass be used to clean photovoltaic modules?

Dust accumulation on the surface of photovoltaic module covers has received increasing attention since 2010. Researchers have been paying more attention to the integration of photovoltaic buildings. This indicates a huge scope for the application of self-cleaning technology (superhydrophobic glass).
