Midsummer WAVE
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.”
