In order to demonstrate the profitability of the photovoltaic installation, it was assumed that the average price of electricity (including electricity sales and distribution fee) in 2020 was 0.5622 PLN/kWh , and its year-on-year increase will be 3.5% [23, 35].
As the installation has a power of less than 10 kW, 80% of the electricity previously fed into the grid can be obtained for free from the discount system [12, 13]. For the economic analysis it was assumed that the efficiency of photovoltaic panels decreases with time and the energy production decreases by 0.8% year on year .
There is the necessity to develop environmentally friendly technologies. Atmospheric conditions affect the electricity production by photovoltaic panels. The source of investment financing affects time of its return. PI and CCE are one of the investment profitability indicators.
For the economic analysis it was assumed that the efficiency of photovoltaic panels decreases with time and the energy production decreases by 0.8% year on year . Table 5 shows the financial benefits of generating electricity by a photovoltaic installation in the building in question over a period of 20 years. Table 5.
We then evaluate the investment in a photovoltaic plant with a capacity of 5000 kW located in eastern Spain, assuming it started its activity in different years which coincide with changes in the regulatory framework. The results show the relevance of the initial outlay costs for the profitability of photovoltaic power plants. 1. Introduction
The surplus of generated electricity goes to the power grid. When selecting the power of the installation, one can assume that in the Polish insolation conditions, 1.25 kWp of the power of the photovoltaic installation is selected for each 1000 kWh of energy consumed annually [5, , , , , ].
