The power from the solar cells should amount to 20 megawatts and the electricity generation capacity to 18 gigawatt hours, which corresponds to 7,500 apartments' electricity use in one year. Sweden's largest plant today, Svea Solar's solar park in Sjöbo in Skåne, has an estimated annual production of 6.3 gigawatt hours.

Construction of the solar park will be started in March and it is expected to be able to supply electricity at the end of the summer.

Electricity to tenant-owner associations

“It feels fantastic that this project will be a reality. The benefit of solar PV is twofold. We offer our condominium associations solel while contributing to the conversion to renewable energy, "says Jon Leo Rikhardsson, CEO of HSB Södermanland, who together with the company Energiengagemang is behind the plans, in a press release.

The idea is that members of HSB should be allowed to join an economic association and buy shares that can cover up to 90 percent of the associations' electricity needs.
