Energy storage photovoltaic solar energy in Tampere Finland

Can solar power improve the profitability of buildings in Finland?

LUT University has investigated how the profitability of solar electricity could be improved in different types of buildings in Finland. Researchers have debunked myths related to the orientation and dimensioning of solar photovoltaic systems and sales of surplus electricity.

Does Finland have solar energy?

Contrary to popular belief, Finland’s solar energy potential doesn’t fall short of that of Central Europe. In the summer, the long days and nearly round-the-clock sunlight compensate for the dark winters. This article's Finnish version was first published in February 2019 and has been updated in June 2023.

Is solar electricity a viable alternative to self-consumption in Finland?

In Finland, solar electricity has so far been a financially competitive alternative only if the self-consumption rate has been high. Now, however, the situation is changing, as solar farms are being built to produce electricity to sell directly to the main grid.

Why is Finland a good place to install solar panels?

"Finland’s advantage is its low atmospheric temperature, which improves the efficiency of solar photovoltaic cells. The colder it gets, the better the solar panels work. Solar panels can also withstand snow loads if they are installed following directions.

How much solar energy will Finland produce by 2050?

LUT has modeled an emission-free energy system and demonstrated that the share of solar energy in Finnish energy production should rise to 10 percent by 2050. That would mean a leap from the current 635 megawatts to 35 000. The rooftop potential of all Finnish buildings (residential, administrative, industrial) is about 34 000 megawatts.

What is the rooftop potential of Finnish buildings?

The rooftop potential of all Finnish buildings (residential, administrative, industrial) is about 34 000 megawatts. In other words, there is a great deal of untapped potential atop our buildings to further the green transition. In the future, two thirds of our daily need for energy will come from renewable sources
