In the article, a one-year energy analysis of 4 on-grid solar stations with capacities of 49.5kW, 53.76kW, 39.6kW and 52.8kW installed on the roof of the building was carried out. It is important to know the efficiency of the use of such solar plants in the world, gradually abandoning the amount of traditional fuel and switching to green energy. Payback periods and CUF coefficients of the station were calculated using the annual energy production. An average payback period of 4.24 years was found for the stations. The best result for CUF belongs to IV station equal to 17.4%, and the smallest value is equal to 8.21% for II station. The annual amounts of energy produced were 58.79MWh, 38.76MWh, 50.05MWh and 80.67MWh, respectively. Despite the high temperature and pollution, the stations had their best energy production in June. In the future, such solar plants on the roof are considered promising projects, because they do not require additional space and are the reason for the cheapest initial investment.
