Boost solar yield
Green roofs create a cooler climate around panels, increasing energy output by up to 40%.
HARMONY BETWEEN GREEN AND ENERGY
Sustainable energy has never been more important. With rising demand and new regulations, solar panels are becoming the norm for both new builds and renovations. Efficiency is crucial. A solar green roof delivers twofold benefits: renewable energy production and vibrant greenery. The synergy of panels and plants even boosts solar efficiency by up to 40%.
Two-in-one solution
Generate clean energy and green your roof at the same time.
Future-proof buildings
Meet energy regulations while enhancing sustainability and design.
Our solutions
POWERING THE FUTURE TOGETHER
The global demand for clean energy keeps accelerating. Solar solutions for both new builds and renovations will increasingly become a requirement. For architects, developers and governments, efficiency and integration are key. At the same time, building owners and users expect solutions that deliver high efficiency and a strong return on investment. The key question: how can energy generation be combined with sustainable, futureproof building design?
“The municipality of Amstelveen is extremely proud of this owners' association for having realised this innovative project.”
VVE Maccabiadelaan realised the first Dutch green roof combined with Over Easy Solar units — 500 m² Sedum and 94 panels.
GREEN ROOFS MEET SOLAR POWER
Why choose between energy or greenery when you can have both? With Sempergreen’s solar green roofs, rooftops become multifunctional: producing energy, cooling buildings, and supporting biodiversity. Every roof can deliver green power, from biodiverse to lightweight, ballasted or pitched.
POWERFUL PARTNERSHIPS
The strength of a solar green roof lies in collaboration. Sempergreen provides the proven green roof systems, while our partners Over Easy Solar and Contec deliver the most advanced solar solutions. Together, we combine the best of both worlds: vegetation that cools, with solar technology that maximises energy yield. By joining forces, we create integrated rooftop systems that are efficient, reliable and future-proof. This partnership approach ensures every project benefits from specialist expertise – resulting in the most effective combination of nature and technology for sustainable cities.

YOU DON'T HAVE TO CHOOSE
With our all-in-one green systems, every roof becomes more than just a place for solar panels. We integrate renewable energy with water management and biodiversity in one complete solution. The vegetation layer retains rainwater and eases sewer pressure, while keeping solar panels cooler for higher efficiency. At the same time, it creates a thriving habitat for bees, butterflies and birds. Depending on your project’s goals, the system can be designed for maximum water buffering, or as a biodiverse version with herbs and grasses. The result: a multifunctional roof that generates clean energy, boosts nature and prepares cities for the future.
GET ADVICE FOR SUSTAINABLE SOLAR POWER
Got questions about solar? No worries! With just a few quick steps we’ll guide you to the right solution and provide customised advice for your project.
Boosting efficiency
Solar panels perform best under the right conditions. That’s where greenery makes the difference. Plants lower rooftop temperatures, preventing panels from overheating and improving their efficiency. Vertical placement ensures that every panel captures sunlight while leaving space for vegetation to thrive. This combination not only generates more renewable energy, it also cools buildings, cleans the air and enriches biodiversity. By merging technology with nature, our solar green roofs unlock untapped potential in every city.
Smart solar investment
Solar power is one of the most cost-effective ways to reduce carbon emissions and cut energy bills. By generating your own renewable energy, dependence on fossil fuels decreases while long-term savings grow. The falling cost of solar technology, combined with rising energy prices, makes investing in solar more attractive than ever. Many regions also offer subsidies or tax incentives, further improving the return on investment. Beyond financial benefits, solar power demonstrates a clear commitment to sustainability, helping buildings meet stricter regulations and climate goals while contributing to a cleaner, greener future.
SOLUTIONS FOR GREEN ENERGY
Sempergreen provides proven systems that seamlessly combine solar energy, greenery and design flexibility. From flat to pitched roofs, our solar green roof solutions are ready to install, optimising energy yield, extending roof lifespan and contributing directly to climate goals.

Everything about solar power
We answer the most common questions about Solar Power. Need something more specific? Just contact us directly.
Can solar panels be installed on a green roof?
Yes, absolutely. Solar panels (PV) and green roofs work perfectly together and even improve each other’s performance. Installing a Sempergreen Solar Green Roof on a flat or pitched roof offers multiple benefits. Besides improving local biodiversity and purifying the air, the vegetation provides natural cooling. This cooling effect increases the efficiency of solar panels by 6–10% and extends their lifespan by keeping them at a lower operating temperature.
Does Sempergreen also supply solar panels?
Sempergreen provides complete Solar Green Roof solutions in collaboration with trusted partners.
With the Over Easy Solar vertical panels, you receive a fully integrated system: green roof, solar panels, mounting frames, and all required materials.
With the Solar Sedum Roof or Solar Biodiverse Roof, Sempergreen supplies the complete green roof system including mounting materials and carriers, but excluding the solar panels themselves.
What are the benefits of combining solar panels with a green roof?
Higher efficiency: PV panels produce 6–10% more energy thanks to the cooling effect of the green roof.
Longer lifespan: Lower panel temperatures reduce wear and extend durability.
Biodiversity: Sedum and biodiverse roofs create habitat for bees, butterflies, and pollinators.
Sustainable building: Combining solar and green roofs contributes to higher BREEAM and LEED scores.
Improved rainwater management: Green roofs store and delay runoff, relieving urban drainage systems.
Can solar panels and green roofs be combined on pitched roofs as well?
Yes, Sempergreen systems are suitable for both flat and pitched roofs. On pitched roofs, green roofs and solar panels can be seamlessly combined without technical issues.
Is a solar green roof more sustainable than a regular PV installation?
Yes. By integrating vegetation, the system adds ecological and social value on top of renewable energy production. It enhances biodiversity, reduces heat stress in cities, improves air quality, and makes buildings more climate-resilient.
