In 2020, Eesti Energia, the Estonian state-owned power group, cooperated with residents to build 285 solar power stations for 100 customers in Estonia and Latvia throughout the year, with a total installed capacity of 8 MW. About half of the Grid Off Solar System power stations were built on the ground and the other half were built on the ground. roof. The largest project is a 348 kilowatt solar park, and the smallest is a 3.8 kilowatt small power station.

Through business-civilian cooperation, many individual families and small companies have gained benefits and motivation from the state's encouraging policies, reduced environmental damage, and become producers of renewable energy, not just consumers of electricity. Users produce solar energy by themselves, which reduces the consumption expenditure for purchasing electricity, and also reduces the use of public power facilities and taxes and fees paid to the government. Moreover, the sale of surplus electricity to the grid can also earn revenue. So far, about 2500 customers have sold their electricity to the State Grid, and some customers have locked the sales price at a fixed level of 25 years in order to obtain better benefits.

According to the staff of the State Power Company, Estonia is a good place to produce solar energy. In summer, sunrise is early and sunset is late, and the sun is at low latitudes in winter. Solar energy output will decrease, but it does not mean that there is no production at all. Therefore, more and more customers are interested in this, either independently invest or attract investment, which means that the supply of energy storage services has greater potential in the future.
