11 helio-power regions have been distinguished across Poland:

— Nadmorski

— Podlasko-Lubelski

— Slqsko-Mazowiecki

— Swi^tokrzysko-Sandomierski

— Mazursko-Siedlecki

— Wielkopolski

— Pomorski

— Podgorski

— Suwalski

— Warszawski

— Gornoslqski Industrial Area

The most favorable solar conditions are at the seaside region where since April to September the highest sums of total radiation and the highest number of insolation hours have been observed. Due to the accumulation of over 70% of average sum of annual solar radiation during this period in such region like like in Kofobrzeg is more than 3800 MJ/m2 and this region is regarded as privileged one. Another region of great importance is Podlasko-Lubelskie because of frequent flow of dry air from the Ukraine.

Presented data on the intensity of solar radiation, irradiation and insolation in Poland reveal, that annual solar power potential in Lublin region is quite high. However, in practice its usage is limited by technical possibilities and investment resources of potential users. Real barriers in the development of solar energy usage are connected not with the supply but rather with the demand for this sort of energy.

The research on the usage of solar energy that have been carried out at the Institute of Electrical Engineering and Electrotechnologies for several years are focused on the assessment of the possibility to apply solar systems in Lublin region [1,2]. The solution presented in the paper describes the usage of photovoltaic panels to supply the ozonizer.
