Overall, you’ve worked out a really great and convenient system! The installation was quite straightforward — I managed most of it together with my 15-year-old son.

I combined the Over Easy E-W setup with my existing 10° sloped south-facing panels on a 3.68 kW SMA inverter. This brings me to 7900 Wp in total panel capacity. Even with such a small inverter, I’m seeing very little loss: only around 10% on peak production days (e.g. 5 kWh loss on a potential 50 kWh around June 21st).

That makes this a great solution for adding capacity in inverter-limited systems — especially in places like Flanders where homeowners are limited to 5 kW (single-phase) or 10 kW (three-phase) inverters. You can really expand production without upgrading the inverter.

Over Easy Solar has developed a unique and future-oriented solution that opens up completely new possibilities for solar energy on flat roofs. The vertical, bifacial technology provides high production – especially in the winter months – and the low weight and simple installation make the process both efficient and gentle on the roof. As an installation partner, we greatly appreciate how well thought-out the product is, and how professionally the Over Easy team operates. This is a technology we believe many building owners will take notice of going forward.

Through our framework agreement with Solcellespesialisten, we have installed solar systems using Over Easy Solar on two of our buildings, one in 2024 and one in 2025. We chose this solution due to load-bearing limitations and other technical challenges that made it difficult or impossible to install conventional solar panels. We see particular advantages in the low weight of the system, and especially in terms of maintenance on flat roofs where we are uncertain about the lifespan of the roof membrane.

Working with Over Easy Solar is always professional, efficient, and collaborative. Their vertical solar solution impresses both technically and visually – especially on gravel and green roofs, where the system's added value becomes particularly evident. Most recently, we completed another installation on a gravel roof in Romandy – the first of its kind in the region and already our fifth project with Over Easy Solar in Switzerland. We value Over Easy’s innovative approach and look forward to realising further sustainable projects together.

Over Easy Solar provides technology that we are proud to showcase in Aker Tech House – innovative and forward-looking. Their vertical solar solution delivers strong performance year-round while also preserving the growth conditions for the green roof. The installation was carried out quickly and professionally. For us, sustainability is also about innovation and new ways of thinking, and Over Easy Solar is a great example of that.

As Norway’s national arena, we have high ambitions – also when it comes to sustainability. With Over Easy Solar, we have received an innovative solar energy solution that not only fits our roof, but also sets a world record for the largest vertical rooftop solar installation. The installation at Ullevaal Stadium delivers high performance throughout the year, especially during the winter months, and the low weight and easy accessibility make maintenance simple.
