The graph shows the price and size development of the 60 cell Poly solar panels from 2013 to 2020.
Summary: The price of the solar panels dropped significantly in 7 years, however still, delaying in running your solar installation makes you lose money. Even though the price of the solar panels dropped over the years, the solar yield from the installation not only pays the price of the original panel, but brings also additional profit.
Do not wait any day to make your own energy with solar panels from GWL.
#1) The average price is based on the monthly sales in the peak months of 6 and 7 of each year. The average price includes both retail sales price and volume discount pricing.
#2) This calculation is based on the average sunshine energy typical in central Europe: 1000 W/m2 and 1500 hrs of sunshine. In the south of Europe, you will get significantly better yields, while in the north of Europe, you will get lower yields.
#3) This is a theoretical comparative calculation. In reality there would be additional costs associated with the installation: transport costs, mounting costs, the work-force costs, and the cost of the DC to AC inverters to produce the electricity in 230V AC format.
