The focus of the paper lies on the feasibility evaluation of solar power generation technologies for the power system to achieve the balance of energy generation and support costs in a more efficient way. The case study is based on a time series of examples with an hourly resolution for several years of electricity prices from the Nord Pool power market, power demand and solar generation of Latvian prosumers. Electric energy generation and consumption data from more than 200 clients were collected and used. The article analyses the influence of net metering supporting scheme variants on the profitability of a projected investment of PV batteries. A recommendation to change the current net metering system to a more perfect one, taking into account the market cost of energy, concludes the paper.
