How it works



Describe your roof and what you want – our solar roof designers will design an individual solution for your roof. We offer turnkey contracts.



When you have chosen the solar cell roof that suits you best, Midsummer prepares a cost proposal. After an agreed agreement, we will come out and make a control measurement of the roof.


Financing with a green loan

In collaboration with Hemma and Skandiabanken, we offer the opportunity to finance your solar cells through a loan with a green discount. Read more here.


Manufacturing and installation

After control measurement, your solar panels are manufactured in our production facility in Järfälla outside Stockholm. When the material is finished, our certified installers and electricians perform the installation according to industry standards.



When installation is complete, we will help you to send in the final application to your electricity supplier. When the supplier has approved the final registration, we put the plant into operation and hand over all the necessary documentation so you can feel safe with your installation.


Electricity production

Your roof can now produce electricity from the sun's rays for your own use or to sell to the electricity grid. Midsummer solar panels have a ten-year product warranty and expected peak output of 80% after 25 years.

Mats och Britta, Täby

“Our WAVE panels blend with our roof and with our area, where the original character of houses must be preserved. It’s a positive thing that the solar panels are made in Sweden with a small climate footprint and communication with Midsummer has been smooth. And now the spring sunshine's starting to come through, we're getting our own KwH for the first time!”

Midsummer WAVE
Magnus och Zuzanna, Nacka

“Our interest in Midsummer was piqued when we wanted an integrated solar roof. The combination of installing both new roofing with cardboard and tiles and discreet solar panels reflecting the shape of the tiles meant a tasteful design and made the choice an obvious one. In addition, we appreciate the low climate footprint of the WAVE panels in production.”
