The photovoltaic (PV) industry is evolving rapidly and equipment models are changing and their efficiency is increasing every year and even more often. Consequently, prices are relatively often revised depending on material prices and demand in the industry. Back in 2012, photovoltaic panels cost 5 to 7 euros per watt (Wp). Currently, market prices fluctuate around 50 cents per watt. Of course, beware of low-priced solar panel deals.
Virtually all solar panels are similar in appearance and it is not so easy to determine their quality and origin. Therefore, we recommend choosing a reliable supplier and installer who will take responsibility for the performance of the solar system - the obtained kilowatt hours for many years. It is obvious that the prices of solar panels have become much friendlier, and the PV systems themselves have become more affordable and therefore more popular.
