DRBO Greenenergy offers high-quality bifacial modules that, in combination with SunLit energy storage solutions, ensure maximum efficiency. What are bifacial solar modules? Bifacial solar modules are an innovative technology that uses both direct light on the front and reflected light on the back to generate electricity. Compared to monofacial modules, which only use the front side for power generation, bifacial solar modules utilize light reflected from the ground or other reflective surfaces. This technology leads to an increase in the efficiency of solar systems. The modules consist of cells with a transparent backsheet or a glass-glass construction, which allows light transmission. This enables them to achieve bifaciality factors of 70–90%, significantly increasing the yield of the solar system. Bifacial solar modules are particularly advantageous with increased mounting height or when installed on light-colored ground, as reflected light (albedo) is utilized. DRBO Greenenergy uses these modules in combination with balcony power plants and storage systems for private customers. How do bifacial solar modules work? Bifacial modules work by absorbing light on both the front and back sides. The front side absorbs direct sunlight, while the back side utilizes diffuse, reflected light. The bifaciality factor describes the yield of the back side in relation to the front side and can provide between 10–30% additional yield, depending on the installation conditions. The cells are active on both sides and equipped with grids that dissipate the current. The transparent back allows light to pass through, while reflective materials such as white foils further increase the yield. In practice, bifacial solar modules can generate up to 30% more energy under ideal conditions. DRBO Greenenergy combines these modules with microinverters to optimally utilize the performance of the solar system. What are the advantages of bifacial solar modules?

The glass-glass design makes them particularly resistant to weather influences and increases the lifespan of the modules. Due to their higher efficiency per area, bifacial modules require less space, which leads to a reduction in the Levelized Cost of Energy (LCOE). In the event of snowfall, the front side melts faster because the back side radiates heat. These properties make bifacial modules particularly attractive for tenants who can find an effective solution in DRBO Greenenergy's balcony power plants, supplemented by the powerful SunLit storage solutions. When are bifacial solar modules worthwhile? Bifacial solar modules are particularly advantageous when the albedo value of the ground is above 20% and the modules are mounted at least 1 meter above the ground. They achieve the highest yield in open spaces with light-colored ground or reflective surfaces. In these conditions, the yield can increase by 15–25%. Bifacial modules are less suitable for shady roofs or dark surfaces. Important factors for choosing the right module are the mounting height, the tilt angle of the modules, and the reflection of the ground. In solar parks with reflective gravel or on balconies with a bright background wall, bifacial solar modules from DRBO Greenenergy offer an excellent solution. How to install bifacial solar modules correctly? The installation of bifacial solar modules requires careful planning to achieve maximum yield from the back side. The modules should be mounted 1–2 meters above a reflective surface, with a tilt angle of ideally 10–30°. It is important to avoid shading on the back of the modules, as this can significantly reduce the yield. The use of transparent mounting structures is recommended to avoid shading the back. Bifacial modules require special spacing to optimally utilize the albedo effect. DRBO Greenenergy's balcony power plants offer plug-and-play kits that enable easy and efficient installation. Professional electricians ensure safe wiring and maximize earning potential. Criterion Monofacial modules Bifacial modules Light utilization Front side only Both sides Yield increase Base +10–30% Ideal for Shady roofs Open spaces, light-colored ground Cost Lower Higher, but more efficient Durability Good Very high (glass-glass) What return can you expect from bifacial solar modules? The return on bifacial solar modules heavily depends on the environmental conditions. With an albedo of over 20% and a mounting height of at least 1 meter, the annual yield can increase by 15–25%. The specific yield is 400–600 Wp/m². In Germany, bifacial modules achieve approximately 1,200–1,500 kWh/kWp annually.
