Solar energy

Clean energy

Solar energy is a clean and renewable energy source that reduces greenhouse gas emissions and dependence on fossil fuels. It is suitable for both residential and large-scale energy park solutions. Thanks to technological advancements, solar energy is becoming increasingly affordable and efficient.

Our solar parks are located in Estonia and Poland

We entered the solar power market in 2017, establishing a solar power station on the roof of the Estonia dairy farm in Järvamaa, where we installed 644 solar panels.

We currently produce solar energy in Estonia and Poland, where we have a total of 43 solar parks. Our solar parks contain over 100,000 solar panels in total.

New solar power plants

Purtse Solar Park

We established Estonia's first hybrid wind and solar park near Purtse in Lüganuse municipality.

What makes this project unique is the integration of the wind and solar parks into the same connection point to the main grid, using the same equipment to feed electricity into the grid. Since wind energy typically generates more electricity in the fall and winter, while solar energy produces more in the spring and summer, the amount of electricity fed into the grid is more stable, making better use of the connection.

The solar park (32 megawatts) covers about 45 hectares and houses nearly 49,000 Yingli Solar panels, which produce approximately 32 gigawatt-hours of renewable electricity annually. Purtse Solar Park is Enefit Green's largest completed solar park.

Estonia Solar Park

We established a solar power station (3 megawatts) on the industrial territory of the Estonia mine in Ida-Viru County. This is the first solar park in Estonia located on a 27-meter-high waste rock embankment. This setup helps reduce shading losses, making electricity production more efficient.

Previously mined areas, as well as other low-value lands, are highly suitable for the construction of solar parks. Developing renewable energy in industrial areas serves multiple environmental purposes. On the one hand, waste rock from mining is repurposed as construction material, while on the other, the mining site is powered with green energy.

This is the second solar park we have built in an industrial area. In May 2019, the Laaskõrve solar park near Kohtla-Nõmme in Ida-Viru County was completed.

Four exciting facts about solar energy production


Solar panels should be installed at an angle of about 35-40 degrees to the ground, as this ensures maximum annual productivity in our region.

Due to high solar radiation and low temperatures, solar parks achieve the highest instantaneous production in March-April.

In Estonia, solar parks usually generate the most electricity in May, as the days are quite long and the temperature is lower than in June-July. Lower temperatures help increase efficiency.

It is also possible to generate energy in cloudy weather, because solar radiation reaches the solar panels through the clouds as well.

Take a virtual tour at the wind and solar park in Paldiski


We have prepared an exciting tour so that you can go on a ride on the wind turbine nacelle and on a walk at the solar park, the annual electricity output of which is equivalent to the average annual consumption of 300 Estonian homes.
