Myths about photovoltaics

Despite the upcoming changes in electrical law, photovoltaics in Poland is still doing great, or even better. Although this increase is probably temporary due to the need to install the installation by the end of the year in order to be able to use the “old” energy settlement system with the energy company, it seems that the decline after the new year will not be as significant as some may think. . The fact is, however, that the unflagging popularity of solar batteries as a method of saving electricity results in a constant increase of rumors and harmful half-truths, usually written by home-grown specialists. Which of them have you already heard about?

We all know that our country is not famous for its year-round summer, but we do not suffer from an exceptional lack of sunlight, after all, every day, regardless of the season, we can clearly distinguish day from night and exactly such availability of sunlight is enough to produce enough energy, and electricity bills have even decreased to the level of fixed charges. The key to success is to properly select the power of the installation in terms of the household needs and its appropriate location with respect to the angle of incidence of sunlight, so as to be able to enjoy free energy all year round.

This is another myth that has roots in the previous one. Naturally, some winter days are cloudier and certainly shorter compared to summer, but this only affects the efficiency of the installation. Here again, it is particularly important to select the appropriate power of the panels individually to the needs of each home. An installation with a higher nominal power will, even in winter, produce enough electricity to meet most or even the entire electricity demand. Of course, panels covered with snow, which will not have access to light, will not produce electricity at all, so we emphasize again how important it is that the installation is properly designed and installed. The appropriate angle of inclination of the battery will make it almost impossible for layers of snow to accumulate on the surface of the cell, and if this happens, it is important when planning the installation to take this eventuality into account and ensure good access to the panels to safely remove the snow cover.

Properly designed and installed photovoltaic panels and their systematic maintenance virtually minimize the risk of fire to zero. We wrote about how to prevent spontaneous combustion of the installation in the article about the dangers of photovoltaics. We encourage you to read this topic in more detail and remind you that the basis for the safe use of the installation is not only the quality of the installation itself, but also the quality of the installation. Therefore, if you do not feel up to installing the panels yourself, choose the help of a company that has been dealing with the topic for several years and enjoys good opinions, because your and your family’s safety may depend on it.

In our opinion, this is a drama that is disproportionate to the situation, especially since we currently know nothing about whether, along with changes in the exchange of energy with power plants, anything will change in terms of co-financing investments in photovoltaics. This is an important aspect because it is worth considering, especially in the case of people who will install home installations after January 1, 2022, whether it is more profitable to install photovoltaics with a higher nominal power. Undoubtedly, this concept generates a higher initial cost, but firstly: we can still apply for funding from aid programs, such as Moje Prąd; secondly: the cost of setting up the installation can be fully deducted from income tax, which in retrospect reduces the costs incurred to zero; and finally, thirdly, as we have already mentioned: a larger installation in the solar season will produce more electricity than the household demand, therefore – more energy will be sold to the general grid, and in winter the possible demand for electricity from the power company’s connection will decrease and this ratio will still be profitable, even despite differences in market prices for selling and purchasing energy. Additionally, a thoroughly thought-out installation will enable you to actually earn money from it in the future, and not just save on energy prices, as was the case so far

This is completely untrue, because while it is difficult to convert the costs of investing in photovoltaics into electricity bills and, in this context, talk about the profitability of the project, government and regional aid programs promoting the use of renewable energy sources have a real impact on the final settlement. You just need to be interested in this topic, because while electricity from the sun actually produces itself, collecting invoices and settling PIT will not happen on its own. However, we have already written about deducting photovoltaics from income tax, so we encourage you to read this article.

Well, a bell is tolling somewhere… However, a permit is required to install an installation above 50 kW, and such energy demand in residential buildings is very difficult to achieve and is particularly rare.
