Are transparent solar panels possible?

Transparent solar modules, also known as transparent photovoltaics, let up to 60% of visible light pass through while converting invisible UV and IR light into electricity. They are ideal for windows, facades, and greenhouses, with efficiencies of 5–12%. DRBO Greenenergy offers suitable solutions with SunLit storage systems for maximum efficiency.

What are transparent solar modules?

Transparent solar modules consist of transparent glass or films with semi-transparent solar cells that allow light to pass through yet still generate energy. They filter invisible light and achieve transparency of 30–60%. These modules offer aesthetic integration into buildings and enable the use of natural light without sacrificing solar power. The efficiency currently ranges from 5 to 12%, making them particularly interesting for applications such as windows, facades, or conservatories.

DRBO Greenenergy has added transparent solar modules to its product range and combines them with innovative storage solutions from SunLit. This allows both private individuals and companies to benefit from this technology. The modules are particularly suitable for balconies, terraces, and other areas that cannot accommodate traditional solar panels.

How do transparent solar modules work?

Transparent solar modules convert invisible UV and infrared light into electricity while allowing visible light to pass through. The solar cells usually consist of organic or perovskite materials that absorb light wavelengths such as blue and red light, while green and yellow light are transmitted. These technologies allow the module to offer up to 60% light transmission while simultaneously generating electricity.

The functionality of these transparent cells is based on innovative tandem technology, which combines two layers of different materials to increase efficiency. Current models achieve an efficiency of 7–12%, with transparency varying from 30% to 60%. DRBO Greenenergy is already working on solutions where transparent solar modules are combined with bidirectional inverters and powerful storage systems to achieve maximum efficiency with minimal space requirements.

What are the advantages of transparent solar modules?

Transparent solar modules offer many advantages, especially in terms of aesthetics and space utilization. They integrate seamlessly into modern buildings and enable the generation of solar power without the need for additional surfaces such as roofs. With energy savings of 20–30% and a payback period of 5–8 years, they offer an interesting way to reduce energy costs.

The flexibility of these modules is also evident in their versatile applicability. They are particularly suitable for urban areas, as they do not require direct sunlight on roof surfaces. At the same time, through agri-PV applications, they offer farmers the opportunity to protect plants from excessive sunlight while generating electricity.

DRBO Greenenergy highlights these advantages by combining transparent solar modules with robust glass-glass structures and efficient storage systems, which are particularly suitable for tenants and homeowners.

What are the disadvantages of transparent solar modules?

Despite their many advantages, transparent solar modules have some drawbacks that may limit their broader application. The main disadvantage is their lower efficiency compared to conventional, opaque solar modules. While opaque modules can achieve an efficiency of over 20%, transparent modules currently range from 5–12%. The higher costs of 20–50% compared to traditional modules and the longer payback period must also be considered.

In addition, durability is an issue, as thin-film technology ages faster and may require regular maintenance. For private users with limited space, the use of transparent modules may be less economically viable due to the higher costs and lower efficiency.

However, DRBO Greenenergy offers solutions to mitigate these disadvantages, for example, by using refurbished storage systems and taking advantage of subsidies that facilitate entry.

Are transparent solar modules suitable for private users?

Yes, transparent solar modules are particularly suitable for private users who want to use limited areas such as balconies or facades for electricity generation. These modules offer an output of 100–300 kWh per year and square meter, which can cover a significant portion of household electricity needs. Especially with rising electricity prices and the possibility of using subsidies such as the KfW funding, the profitability of the installation increases.

For tenants, DRBO Greenenergy offers a simple solution with plug-and-play systems that do not require major structural changes. This allows tenants to benefit from the advantages of transparent solar modules without their apartment or building having to be permanently altered.

How to install transparent solar modules?

The installation of transparent solar modules is relatively simple and can usually be done within 1–2 hours. The modules are attached to glass surfaces either with clamping sets or special adhesives and then connected to micro-inverters. The assembly requires no drilling, making the installation particularly suitable for tenants and homeowners without structural interventions.

For a correct installation, electricians should be consulted to check the grid connection and ensure that all safety requirements are met. DRBO Greenenergy offers complete packages that contain everything necessary for installation, including brackets and inverters.

Can transparent modules be combined with storage systems?

Yes, transparent solar modules can be excellently combined with storage solutions such as DRBO Greenenergy's SunLit storage systems. This enables effective use of the generated electricity, as excess energy can be stored and retrieved when needed. The use of bidirectional inverters is particularly advantageous, as they can store electricity at night and discharge it during the day. This optimizes self-consumption and significantly shortens the payback period.
