  • Our first Installation in Austria: Easy mounting Vertical Solar Panels on Green Roofs

    We at Over Easy Solar are proud to announce the successful installation of our vertical bifacial solar panels in Austria, marking a significant milestone for our company. This project took place on the green roof of "Amann die Dachmarke" in Vorarlberg, a prominent Austrian roofing company renowned for its expertise in a variety of roofing products and innovative green roofing solutions. Amann die Dachmarke, led by CEO Marius Amann, has been an exceptional partner in this project. With their extensive knowledge and commitment to green roofing, they provided the perfect platform for showcasing our technology. This installation, with a capacity of nearly 7 kWp, is projected to generate around 7,000 kWh of clean energy annually. As Marius Amann expressed, “We are happy to showcase this innovative product on our green roof and educate people on the symbiosis of green roofs and solar.” This collaboration not only highlights the innovation in green energy solutions but also serves as an educational tool, demonstrating the mutual benefits of integrating solar panels with green roofs. Our vertical bifacial solar panels provide partial shading to the green roof, which can lower temperatures by up to 10 degrees compared to non-shaded areas. In return, the green roof offers a cooling effect, helping the solar panels maintain their optimal operating temperatures even on hot days. This symbiotic relationship enhances the efficiency and longevity of both systems. The feedback from the installer company has been incredibly positive. They noted, “The installation was self-explanatory, we didn't even need the installation manual to install it. It was also very quick and comfortable to work with.” Such comments reinforce our commitment to delivering user-friendly solar solutions that are not only effective but also easy to mount. According to the Austrian Green Market Report, every tenth roof in Austria is built as a green roof, highlighting the immense potential for combining green roofs with solar panels to produce sustainable energy. As we expand our presence in Austria, we look forward to contributing significantly to the country's green energy landscape. Our installation in Vorarlberg represents a significant step towards a greener future. We are excited to continue demonstrating how innovative technology and ecological roofing solutions can work together to create a sustainable energy ecosystem.

  • Increased Solar Capture Rates From of Vertical Bifacial Solar Panels

    This article will explain why vertical bifacial solar panels produce higher value energy compared to conventional solar panels, helping understand why investing in this technology is beneficial and can be more future-proof than investing in conventional flat roof solar solutions. Understanding Capture Rates and Capture Prices for Solar Capture rates refer to the proportion of the average power price that a power production technology achieve compared to average prices in the market. Capture prices are the actual prices at which this electricity is sold in the markets. For solar energy producers, these metrics are critical as they determine the financial return on their investments. The Importance of Capture Rates for Solar Energy Dynamic pricing of energy is becoming increasingly important for solar installation owners. Many electricity customers in Scandinavia, Germany, and other countries are already experiencing dynamic pricing. This trend is expected to grow, enabling customers to actively participate in the power market. Solar power often saturates the market during midday, causing prices to drop significantly. In contrast, power prices usually peak during the morning and evening when demand is highest, and solar output is lower. In 2024, we now start seeing the real effects of this trend with a lot of zero or negative midday prices. The price typically peaks from 7-9 in the morning and from 18-21 in the evening, while staying low or zero in the hours 11-15, as can be seen in the data illustration below. The Higher Capture Rates of Vertical Bifacial Solar Panels A 2023 study by the German management consulting firm Enervis showed a significant difference in future capture rates between conventional and vertical bifacial solar panels (see full report). By 2030, capture rates for conventional solar panels are expected to average at 53%, decreasing to 31% by 2040. Vertical bifacial solar panels, however, are projected to maintain a capture rate of 73% in 2030 and 52% in 2040. This represents roughly 40% higher capture rates in 2030 and 60% higher in 2040 compared to conventional panels. Recent Data for Capture Rates for Solar Energy Recent data highlights the growing importance of vertical bifacial solar panels. In May 2024, capture rates for conventional solar panels were as low as 50% in the German power market, according to independent LinkedIn posts by Thomas Rosentopf from Enervis and the energy expert Julien Jomeaux. Other vertical solar specialists are talking about an improvement in VPV increased capture rates from 5% in previous years to 15% for 2023 in the German power market, demonstrating the enhanced efficiency of vertical bifacial panels. "May 2024 was the first month ever we saw solar capture rates below 50% in Germany" Thomas Rosentopf, Enervis Over Easy Solar’s own calculations, based on data from solar installations in Oslo and the NO1 price zone in Norway for May 2024, show a capture rate of 76% for conventional solar and 89% for VPV (vertical photovoltaics). This represents a 17% improvement, and these data align well with the projections proposed by Enervis in the earlier mentioned report. The graphics below illustrate the power price variations in the Norwegian market in May 2024, alongside real measurements from a conventional flat roof solar installation and a vertical PV solar installation close to Oslo. You can clearly understand why VPV delivers higher value, producing in the hours of higher power price in the morning and in the afternoon. Maximizing Solar Energy Value with Vertical Photovoltaics The higher capture rates of vertical bifacial solar panels mean that energy is delivered at times of higher power prices, generating more value per produced kWh. Additionally, the value of self-consumption versus exports further enhances the financial returns. Over the next decade, VPV units are expected to offer over 50% higher returns per installed kWp compared to conventional solar panels, making investment in VPV a much better business case in the long run. Investment in VPV Gives Better Financial Returns in the Long Run Investing in Over Easy Solar’s VPV Units with vertical bifacial solar panels is a sound decision that promises higher value energy production and substantial financial returns in the long run. As dynamic pricing becomes more prevalent, vertical bifacial panels will be crucial for maximizing solar energy investments, and it will provide value to the power grids and our cities by producing energy outside of peak solar hours.

  • World record in vertical solar panels on rooftops – 248.4 kWp on the Norwegian National Football Stadium

    In May 2024, our partner Solenergi FUSen mounted the biggest Over Easy Solar installation so far – a 248.4 kWp solar installation on the rooftop of the Norwegian National Football Stadium – Ullevål Stadion. This installation is now the largest rooftop vertical bifacial solar installation in the world. It was installed on an existing bitumen rooftop – the mechanical installation was done in a matter of few days. Solar Installation at Ullevål Stadium Sets World Record This unique installation entails 1242 vertical solar units of 200 Wp, positioned to harness the full potential of the sun’s rays. This installation is estimated to generate an impressive 219 000 kWh per year clean energy. Vertical Solar Panel Benefits Showcased at Ullevål Stadium Analysis from Over Easy Solar’s pilot projects demonstrates that vertical solar panels can achieve more than 20-30% higher specific yield than traditional flat roof solutions. The solar panels are in this installation oriented in a general south-north orientation (20 degrees east of south), providing a energy distribution with higher energy yield in winter months. Vertical solar panels also yield increased performance during winter due to less snow coverage and increased production from the high albedo of snow. Other key benefits that are appreciated by the customer is the low weight of the installation and the easy access to the rooftop for inspection and local repairs of the roofing membrane. We’re proud to present this as the largest vertical rooftop project in the world to date, but we are also certain that the record will not last long.

  • Solar panels and green roofs – how to plan for the best combination?

    Modern urban buildings must take maximum advantage of all spaces, including rooftops. In many cities, there are regulations that require green roofs, and often architects and planners believe that it rules out solar energy. But the good news is that you can make green roof and solar a great combination! Types of green roof There are different types of green roofs, and many ways to build them up. Generally, a layered structure consisting of a root barrier, a drainage system, a substrate (soil) and plants build up the green roof. Most green roofs are so-called extensive green roofs, planted with sedum plants. Extensive means that they are optimized for large area coverage, low weight and low maintenance needs. Sedum plants are succulent plants that can hold a lot of moisture and therefore resist long periods of little rain and the strong sun and heat that rooftops are exposed to. The sedum plants typically grow 5-15 cm over the rooftop, depending on the season, the substrate thickness, climate and maintenance. Extensive green roofs are designed to be light-weight, and typically weigh 50-150 kg/m2 when soaked in rainwater. Extensive green roofs are good for combination with solar panels. The other main type of green roof is intensive green roofs, which offers thicker soil substrate and more biodiversity. The weight is high (150-800 kg/m2), and therefore put high demands on the building structure. Plants include bushes, weeds, grasses and sometimes even trees, and the typical plant height is in the range of 30-60 cm. Intensive green roofs are difficult to combine with solar panels. Read also: Why are green roofs so important? Checklist for combination roofs To combine green roofs with solar energy, you need to plan well. There are many examples of installations that don’t work very well. We here want to propose a set of design principles and guidelines for planning a good combination. Know your type of green roof To plan a working solar installation on a green roof it is important to know the type of green roof to ensure that you select a suitable solar solution. The substrate thickness, plant height and maintenance needs are crucial to know. Plan for the right roof load While green roofs in themselves add substantial weight to the roof, adding a solar installation may end up with doubling the roof load. For existing buildings, this is important to know in order not to compromise the safety of the building, and new buildings may need to be reinforced with respect to original plans, adding cost and consuming more concrete and other materials in the construction process. Ensure low conflict between plants and solar panels It is important to plan for a solution where the green roof and the solar panels will not be “fighting against each other”. Solar panels may alter sunlight, evaporation and water flow on the roof, and might create unexpected negative consequences. It is important not to completely cover the green roof with solar panels. A conventional east-west solar installation may provide a lot of kWp in theory, but the fact is that plants will end up covering the solar panels to a smaller or larger degree. In general, a green roof solar installation will have less power (kWp) than a completely covering flat roof solar installation. We recommend planning with 50-70% of a the power of a conventional solar installation for flat roofs, otherwise it will be a suboptimal solution both for the green roof and the solar panels. Optimize for easy maintenance Although extensive green roofs require very little maintenance, they need more than traditional dead materials. You must make sure that the green roof is accessible through the lifetime of the building. If planned wrong, as we will see below, the combination of green roof and solar may also generate a much higher need for maintenance than what each solution separately would have. Types of solar installations for green roofs A solar installation consists of solar panels, a mounting system, cabling and an inverter. The type of solar panels and mounting system is extremely important to make a good combination roof. There are three main ways used to build a solar installation on a green roof. Conventional solar panels and conventional flat roof mounting structures For flat roofs without green, regular solar panels that measure about 1 by 2 m in size are mounted into a mounting system in an east-west configuration. The solar panels will cover nearly the entire roof, except for some walkpaths in between the panels for most mounting systems. While this is an efficient and well-established way to build a solar installation, it is not a good idea for combination with a green roof. Why? Because the large solar panels will cover the green roof almost completely. Below the panels there will be a humid and dark environment, which favors the growth of plants that can grow fast to reach the light above the solar panels. These plants will shade for the solar installation and generates a massive maintenance need to remove them continuously through the growth season. The large solar panels will also make the maintenance very difficult, as maintenance personnel will need to lean over the large solar panels without putting much weight on them to remove the weeds in between. This combination is therefore not recommended. Conventional solar panels with a specialized mounting structure There are several providers of specialized structures for usage of conventional solar panels on green roofs, for example the well-established solutions from Bauder and Zinco. These solutions provide an elevated mounting of the solar panels at an angle of 15-30 degrees, with ample space between, for plants to grow and maintenance personnel to move. The elevated and sparse installation of solar panels make them highly exposed to winds and winds can generate substantial lift forces on the structure. Therefore, they need high ballast and may add up to 100 kg or more per square meter of rooftop. When planning such an installation it is crucial that the building is designed for such loads, and, for retrofitting of existing buildings with green roofs, it might not be a viable solution. The roof is relatively easily available for maintenance. However, since the tilted panels will concentrate rainwater on the lower end of the panel, there will often be accumulation of plant growth at the lower end of the panel. Good planners of such installations know this, and intentionally divide the thickness of the green roof substrate on the roof, so the lower end of the solar panel has thinner substrate, in order to avoid growth of tall plants that shade the solar panels on the lower edge. In the end, these installations are well-established in the market, but the installation may be complex, the weight might be high, and therefore it is not always a possible solution. Specialized vertical bifacial solar panels in a specialized mounting structure To address the challenges that arise when using conventional solar panels (weight, maintenance, etc), you might consider a third way to install solar panels on green roofs. An example of this is the system offered by Over Easy Solar. Use of vertical solar panels in combination with green roofs were first tested in Switzerland in 2015, and it offers a solution that may give the best of both worlds. The vertical solar panels do not cover the green roof, so all of the plants get access to rainwater, light and evaporation. Small vertical solar panels mounted at a suitable distance over the rooftop require little or no ballast, making it a very light-weight and easy system to mount. The VPV solution from Over Easy Solar normally only adds 11 kg/m2 to the rooftop. However, you still need to know which type of green roof is under, and for intensive green roofs this is not a recommended solution since tall plants will overgrow the solar panels. In sum, you need to use a specialized system for green roofs. Over Easy Solar's solution with the VPV Unit is a good option, and there are also other alternatives that makes a high-quality and low-maintenance green roof solar installation possible.

  • Ballast for solar on flat roofs – do you really need it?

    Most flat roof solar installations are ballasted. It means, the solar installer will put ballast stones below the solar panels to keep the solar installation in place, and not be lifted off the roof in case of extreme winds. In most cases, Over Easy Solar’s VPV unit eliminates the need for ballast. What exactly is ballast? Ballast for a solar installation is “something heavy” that gives additional weight to the installation, to counteract for lift and push forces generated by wind. In most cases, concrete blocks or stones are used, mainly because such stones are easily available, easy to stack on a pallet, and relatively easy to handle for the installers on the rooftop. How much ballast is necessary for a flat roof solar installation? Depending on the type of installation, the building geometry, and the wind zone, the necessary amount of ballast varies a lot. The need for ballast is especially high on small installations (like a private house or garage), on tall buildings and in areas where you have strong winds. It also depends highly on which mounting system is used – south-facing solar panels elevated at a distance from the rooftop, for example, gives high wind loads and high need for ballast. In the best cases, conventional installations may need only 5-10 kg of ballast on the outer rows of panels in an installation. The worst cases may need over 100 kg of ballast for every panel in the installation. For a private house, we could be talking about several tons of ballast added to one small rooftop. For a higher and larger commercial rooftop in a windy area, we are talking about tens of tons. Why should you care about ballast for a solar installation? For the owner of the solar installation, ballast seems not to be a very big problem. It only lays there, right? But there are some important things you should keep in mind: What is the load bearing capacity of the roof? Not only is the structural strength important, but also the strength of the roofing membrane and the underlying insulation. Both can take damage from a heavy installation, especially if the weight is concentrated on a small surface area. What is the maintenance need of your roof? If you think it is likely that there will be some maintenance work on the roof in the next 30 years, which demands that you remove the solar panels, ballast may be a challenge as it complicates the work on the roof (imagine finding the ballast plan for a solar installation in 15 years from now!). For the installer, ballast is not desired because it introduces more work and logistics with the installation. A wind-exposed solar installation will therefore be more expensive, and installers may be reluctant to take on such projects. Sadly, some installers will also forget the ballast or even manipulate the calculations or the mounting system itself, sometimes resulting in accidents during strong wind events. How much ballast is needed for Over Easy Solar’s VPV unit? In 2023, we published the results of our wind certification. After thorough testing both in digital models and in a physical wind tunnel, we have now proven that our technology is ballast free for most flat roof buildings. Meaning, you can save money on ballast in your solar system and save your roof the strain of a heavy installation. As for other installations, a calculation for each project is needed. Our PV engineers will help you plan your installation step by step, customizing it to the needs of your roof.

  • A Closer Look at the Climate Impact of our Vertical PV Unit

    Sustainability is not just a buzzword; it's a guiding principle for innovation, especially in the world of solar energy. At Over Easy Solar, we're proud to introduce a new concept in the PV industry – prefabricated PV units with vertical bifacial solar panels. The VPV Unit promises to enable more buildings with flat rooftops to install solar, like for example existing sedum rooftops. To further prove and enhance the sustainability, we've partnered with Fraunhofer ISE to conduct a Life Cycle Assessment (LCA), focusing on the carbon footprint of this groundbreaking idea. Product Spotlight Product Name: Over Easy Solar Vertical Photovoltaic (VPV) Unit Product Description: The Over Easy Solar VPV is a solar unit featuring vertically mounted bifacial solar panels on a structural frame. It offers easy transport, lightning-fast installation (over 10 times quicker than traditional systems), simplified logistics, and minimal rooftop assembly. Plus, it makes building maintenance a breeze and can be integrated into eco-friendly building designs, including green roofs. The Global Connection Our production reaches across the globe. While some crucial components are manufactured in China, the structural frame is crafted in Spain and then transported to the assembly facility, also in Spain. This international collaboration ensures we tap into the highest level of quality and expertise throughout our product's journey, but it also introduces challenges that we are highly aware of – such as long transportation distances and risk connected to the working conditions in the PV supply chain in China. Tommy Engvik, Co-founder and Chief Commercial Officer of Over Easy Solar, states: “Sustainability is our primary concern, and it is why we founded the company. We have our feet on the ground, we personally inspect our suppliers’ facilities, and we have clear guidelines on how our suppliers should source materials and inputs for manufacturing” Breaking Down the LCA We have done a Life Cycle Assessment in collaboration with Fraunhofer ISE, following some important principles: Functional Unit: We're evaluating the environmental impact of producing 1 kWp (kilowatt-peak) of our photovoltaic module. Data Sources: We used SimaPro 9.5.0.0 software and drew data from the Ecoinvent 3.8 database, in addition to using Fraunhofer ISE’s own collected data, following the IPCC2021 GWP100 method. System Boundary: Our study focuses on the phase from raw materials to the gate, excluding end-of-life considerations. The Climate Impact Our LCA revealed some crucial insights: Solar cell manufacturing contributes to 57% of the total carbon footprint. Within this, poly-Si, a key component, accounts for 47% of the emissions from solar cell production. PV panel manufacturing, excluding solar cells, sees 58% of its carbon footprint coming from glass. The structural frame plays a smaller role, making up 10% of the total carbon emissions. According to our calculations, the CO2 footprint from the solar energy over the lifetime of the product, will typically be in the range of 15-25 gCO2e/kWh. As a comparison, the footprint for the German power mix in 2022 was 385 gCO2e/kWh (link). What's Next? To make our Over Easy Solar VPV even more eco-friendly, we have some strategies in mind: We're exploring if we can make solar panels with specially sourced low-carbon wafers and solar cells. We're optimizing material usage to reduce waste – for example, we re-use packaging in several steps of our value chain. We're exploring local manufacturing in regions with a higher share of renewable energy sources in their electricity mix and shorter transport distances. We will soon develop an Environmental Product Declaration (EPD) for our product – the first EPD in the solar industry to entail all the materials included in a rooftop solar installation. These steps could significantly reduce our carbon footprint and further highlight the sustainability of our innovative solar solution. At Over Easy Solar, we're committed to working with the best partners and continuously improving our supply chain to create one of the most sustainable solar products available.

  • Energy yield from vertically mounted bifacial solar panels

    More energy in the morning and in the evening with VPV With vertical solar panels you can get two energy production peaks each day rather than one with east-west mounted VPV units from Over Easy! Mounted so the sunlight hits the panels on the east side in the morning and on the west side in the afternoon, you get one peak for the morning coffee and one for the evening activities. The figures displayed above show the energy production profile during a sunny summer day from one of our installations outside Oslo in Norway. As you can see, the energy production profile gives high yields in the morning and evening, and a total yield of 27% more energy during the day for east-west orientation. The energy also comes at a valuable time to stabilize the local electricity grid. The south-north installation has a bit lower yield than the conventional panels, but as can be seen in the following, this is more than compensated for by higher yields during the winter months.

  • VPV (vertical PV) in winter conditions, Oslo Norway

    Many of our customers ask how vertical solar panels work in winter. For the past two weeks we have had beautiful winter weather in Oslo, which shows beautifully how this works. From the data shared in the chart here, we can make some interesting observations: December 1-5: Cloudy winter weather. Under these conditions, vertical solar installations give almost the same yield as a conventional installation on a flat roof with a 10-degree pitch. December 6-12: Sunny days with little or no snow cover. Under these conditions, the yield of vertical bifacial can be very good. On these days, VPV yield is about 450% higher than conventional installation. December 13-18: Snow showers with some sunshine in between. Vertical solar installation gives a good yield, while conventional installation is quickly covered with snow and "lights out."

  • Green roof solar on a logistics building from ASKO

    We are excited to announce that we have another installation up and running in Norway. For ten years, ASKO and NorgesGruppen have been bringing solar energy to rooftops all over Norway. Their strong focus on sustainability has made them an important player in this area. Now, they are taking a big step forward with new technology for flat and green rooftops. As Over Easy Solar, we are proud to join them in this exciting journey. In early 2022, Over Easy Solar installed the first vertical pilot on ASKO'S rooftop, in a project financed by Innovation Norway. This project was a landmark project as the first vertical solar on a commercial rooftop in Norway. This vertical orientation of the Over Easy solution captures the sunlight from dawn to dusk, and gives higher yields in morning, afternoon and winter. Our pilot projects have shown that vertical solar panels outshine traditional flat roof solutions in terms of energy yield, with up to 20-30% higher specific yield. Later the same year, we completed a second installation with ASKO, strengthing ASKO's role as a leader in solar innovation. Drone shots and images from ASKO'S rooftops have been featured in PV Magazine Global and on a video with millions of views on YouTube. Sedum and Vertical PV Units: Green Roof Solar Now, ASKO and NorgesGruppen are advancing sustainable rooftops with their latest project. How? By blending nature with advanced technology. Sedum from Bergknapp AS adds a green touch, with solar panels on top. And this is where Over Easy Solar comes in. Our vertical PV units integrate smoothly with the sedum, forming a harmonious rooftop ecosystem. The panels produce clean electricity while preserving the green look of the rooftop. It's a win-win for both sustainability and aesthetics. Green roofs provide many benefits, such as supporting biodiversity, improving water retention and lowering energy costs. Furthermore, the green roof itself benefits from the partial shading by the panels which helps its longevity, on the other hand the panels also benefit from the cooling effect by the green roof and therefore operate more efficiently. Norway's Solar Energy Landscape Norway’s commitment to renewable energy is evident. Already, hydro and wind power account for over 98 percent of electricity production in the country. Between January 2023 and early June 2023, Norway added 101 MW of new solar PV capacity, bringing the country’s total installed solar PV capacity to 459 MW as of June 2023. Despite its small role in Norway’s energy landscape, solar power holds significant growth potential. With government support and integration into existing renewable sources, it contributes valuably to the country’s transition toward a low-emissions society. In conclusion, ASKO, NorgesGruppen, and Over Easy Solar are creating a new chapter for Norway's clean energy. We thank CRS Elektro AS for managing the electrical installation. This project demonstrates that business partnerships and collaborations can work together with innovative technology to produce clean and sustainable energy.

  • Vertical Green Roof Solar Project in Switzerland

    Together with the Swiss company PlanPRO, a VPV installation was mounted in Beinwil am See, Switzerland, in January 2024. This project demonstrates how we are addressing the challenges of weight and complexity often associated with solar installations on green and flat rooftops. Streamlined Biosolar Installations with Reduced Ballast Requirements The essence of Over Easy Solar's approach lies in its ability to minimize the reliance on heavy ballasting, a common obstacle in traditional solar projects. By deploying vertical solar panels, the company has ingeniously negated wind lift and uniformly distributed transversal and horizontal forces throughout the installation. This method not only simplifies the installation process but also broadens the scope for solar energy applications on structures previously considered unsuitable due to weight constraints. "Our vertical solar panels effectively negate wind lift and, by integrating the installation as a cohesive structure, it evenly distributes transversal and horizontal forces across the installation," said Trygve Mongstad, CEO and Founder of Over Easy Solar. This technical insight emphasizes the practical and efficient nature of Over Easy Solar's system, reflecting the company's commitment to advancing solar technology. A Testimonial to Simplicity: Vertical Solar Panels for Green Roofs The project in Beinwil am See stands as a testament to the system's user-friendly design and effectiveness. PlanPro, a local company, executed the installation of a 10 kWp system atop an existing sedum rooftop with remarkable efficiency. The process showcased not only the ease of retrofitting the system on a green roof but also the satisfaction of the stakeholders involved. “We were impressed at how easy and fast this product can be retrofitted on an existing green rooftop,” remarked Sven Meuschke, Project Manager at PlanPRO in Switzerland. This statement encapsulates the project's success and Over Easy Solar's ability to deliver solutions that meet the practical demands of installation professionals and end-users alike.

  • Combine your Green Roof with a Solar Energy System

    With more and more cities around the world changing the building code and regulation to better adapt to the climate conditions, the cities must combine green roofs systems for retaining water and energy production to conform to the new standards. Previously, it was not possible to fully utilize the roof area for both green roofs and solar. Standard solutions either install the green roof and the PV system in separate areas or install conventional solar panels over the green roof, shadowing the vegetation and hindering growth. Using the Over Easy Solar unit, you can now combine 100 % of your green roof with a solar energy system! The lightweight PV-Units from Over Easy Solar can easily be put on top of your sedum roof without limiting or changing the function of the green roof itself. Both the green roof and the solar panels get plenty of sunlight, with no conflict of area. The Over Easy systems also allows for easy access to inspect, maintain and if needed repair the roof.
