Photovoltaic panels

Photovoltaic panels are widely considered a good alternative to drawing power from a power plant. In our country, more and more such installations are appearing on the roofs of homes and businesses. What makes people increasingly opt for such an investment? The panels are a long-term investment that pays for itself a few years after the installation is purchased. To illustrate to you how this works, we will use the following example: From the 5,000 kW of electricity produced, at a fee of 65 cents per kW of power, roughly 2,500 zlotys can be saved annually. It is often the case that such a large amount of energy is not needed to power the entire house, so the excess energy can be discharged to the grid. If necessary, it can be taken back (80% of the drained surplus) at no cost. Ultimately, a full return on investment can be expected after just 5-8 years. If you use the panels for 20 years, you can save up to 25,000.
