Thinking about installing photovoltaic panels but have doubts? Find out from the article: How do photovoltaic panels work? What is the insolation in Poland and what does it depend on? We will also answer the question: Is investment in photovoltaics profitable in our country? Read more.

Insolation in Poland and photovoltaics

Photovoltaics is a technology that allows solar energy to be converted into electricity. The operation of the panels is therefore impossible without the sun, and the more of it there is, the more efficiently they work. Many people fear that the insolation in Poland may not be sufficient for photovoltaics to work efficiently and profitably. However, these fears are not borne out in practice. The average insolation in Poland is 1000 kWh/m2, which is sufficient to make the installation of photovoltaic panels profitable.

What does the degree of sunshine depend on?

The level of insolation in Poland varies quite a lot, for example the south-eastern area of the country is the most insolated and the northern area the least. Factors influencing these relationships are:

  • terrain;
  • latitude;
  • vegetation;
  • air pollution;
  • microclimate;
  • type of development.

Although the average insolation varies from location to location, the climatic conditions in every region of Poland allow the effective use of photovoltaic panels.

Photovoltaic panels - how do they work?

Photovoltaic panels use the sun's renewable energy to convert it into electricity. It is not only environmentally friendly but also a virtually free way to generate electricity. How does it work?

Photovoltaics on the roof.

Electric modules are made up of photovoltaic cells that convert energy from sunlight into electricity. This phenomenon is called the photovoltaic effect. The direct current generated in this way then flows through an inverter to be transformed into alternating current, which is the current found in electrical sockets. The energy obtained in this way can be used on a regular basis or stored.

Photovoltaic panels - is it worthwhile?

The power of photovoltaic panels is determined under specific conditions, considered optimal for their correct operation. These are, respectively, an insolation of 1,000 kWh/m2 and a cell temperature of 25 °C. Above this temperature, the efficiency of the panels decreases and, despite appearances, the hot climate of countries in southern Europe is not at all favourable for photovoltaic installations. Hot, windless weather can even lead to overheating of the cells.

Modern photovoltaic installations are able to operate efficiently even when it is cloudy. A small amount of light breaking through the clouds is enough to trigger electricity production.

As we mentioned earlier, the average insolation in Poland is 1000 kWh/m2, which is exactly what is used for testing photovoltaic panels. So there is no doubt that the application of this solution in our country is cost-effective and will work effectively. Photovoltaics is a respite for the planet and, in the long term, also saves a lot of money.
