Over Easy Solar's vertical bifacial PV modules, which are specially designed to be efficiently combined with green roofs, were presented at the Solar Solutions Amsterdam trade fair and received second place in the Best Innovation Awards. The new partnership now establishes Sempergreen as the European distributor of Over Easy Solar's PV modules for green roofs, making this solution available throughout Europe.
Lightweight Biosolar Roof
Over Easy Solar's vertical PV units are light and efficient, making them an ideal addition to green roof systems. Weighing just 11 kg/m², the VPV modules require no ballast or mechanical fixing, making installation quick and easy. The lightweight design allows for a complete solar green roof system with a total weight of only 51 kg. This makes Over Easy and Sempergreen the lightest solar green roof system on the market, ideal for new construction and retrofit projects.
Synergistic benefits of green and solar
The vertical PV modules of Over Easy Solar ensure that plants and solar panels complement each other. The plants reflect sunlight onto the solar panels (albedo effect) and cool the roof, significantly increasing the energy production of the PV solution. The vertical design allows the green roof to benefit from partial shading by the modules, while still receiving sufficient light and rainwater and remaining easy to maintain.

Trygve Mongstad, Founder and CEO of Over Easy Solar, emphasizes: “Our solution is specifically designed to work in harmony with plants. The partnership with Sempergreen will contribute to a more sustainable future by maximizing the potential of urban rooftops. Together, Over Easy Solar and Sempergreen provide the building blocks for future-proof and double sustainable rooftops for existing and new buildings.”
High current vertical bifacial panels
Over Easy Solar's vertical bifacial solar panels capture light on both sides. This results in an extra high energy yield during the day. The vertical arrangement and the two-sided panels also achieve a more even energy distribution, which reduces the risk of overloading the electricity grid and also supplies energy during periods of higher electricity prices. This particular energy production profile, with two peak production cycles per day, more productive hours and good performance in winter conditions, results in a high yield per watt peak.

Kai van Gool, Business Development Manager at Sempergreen, explains: “Green roofs and solar roofs no longer have to compromise each other. Now it is even easier to make roofs optimally sustainable by combining both solutions. This not only results in a greener living environment and an increase in biodiversity, but also increases the value of the building. We are very pleased that Sempergreen, as a distribution partner, can now provide a fantastic lightweight solution for new solar green roofs and retrofit projects on existing sedum roofs.” (hcn)
