Over the past 20 years, the price of photovoltaic systems has decreased by an average of 5 percent each year. The investment in a well-installed and designed photovoltaic system is amortized in 7 years. In recent years, the price of energy has decreased and this trend will continue, so this will lead to a period of amortization of the investment.

Photovoltaic panels produce energy based on the amount of sunlight they are exposed to, regardless of the season we are in. They are less efficient when temperatures are very high or they are covered in snow or dust.

Dust can reduce the efficiency of photovoltaic panels by about 5%. That is why it is recommended to clean them once a season. The panels have no moving parts, so maintenance costs are not high.

This is another myth! A 165X100 cm panel, with a power of 250 Wp produces an average of 885 Wh/day and can power several consumers: your TV, laptop, mobile phone or LED bulbs.

The price of photovoltaic systems has been steadily decreasing as their use has expanded over the past 10 years. We now find photovoltaic cells on garden lighting systems, external batteries for mobile phones, boats or airplanes.

The increasing promotion of this technology, the advancement of research in the field, and the fact that more and more states have policies to implement subsidy policies for solar energy systems, contribute to better accessibility of this energy.

The investment in a photovoltaic system technology is recovered in approximately 7 years, by decreasing electricity bills, as well as by increasing the market value of the property where they are located. As for their lifespan, it is at least 25 years.

The closer the production is to the place of consumption, the lower the transportation or distribution losses are and thus you save money.
