How do transparent PV modules work optimally?

The energy transition is progressing, but many buildings do not utilize their solar energy potential because traditional modules block light. Transparent PV modules from DRBO Greenenergy solve this problem by allowing up to 90% of light to pass through while efficiently generating electricity. This innovation enables decentralized energy production on windows, facades, and balconies, reducing costs by up to 30% and increasing independence from fossil fuels.

What are the current challenges in the solar industry?

The solar sector is growing rapidly, but lack of space in urban areas hinders its expansion. According to the German Solar Association (BSW-Solar), only 18 GWp of new capacity was installed in 2025, despite a potential of 50 GWp. The main reason: 70% of households and tenants do not have roof space for opaque modules. (https://www.solarwirtschaft.de)

Cities like Berlin and Munich are struggling with high electricity prices, which rose to 38 cents/kWh in 2025. Facades and windows remain unused, leading to a loss of 40% of potential generation. DRBO Greenenergy addresses this with transparent solutions for tenants and owners.

Dependence on grid electricity increases commercial energy costs by 25% annually. Without innovative modules, companies miss out on savings of up to €5,000 per year for 100 m² of facade area.

Why do traditional solutions fail in transparency?

Traditional PV modules achieve efficiencies of 20-22% but block 100% of light. They are only suitable for roofs, not for light-sensitive areas like offices or apartments. DRBO Greenenergy stands out with its semi-transparent technology.

Glazing with films or small modules only generates 5-10% of the power and requires complex installation. Costs are €200/m², with an ROI only after 12 years. DRBO's transparent modules shorten this to 6-8 years.

Mechanical mounts damage facades and require permits. In comparison, DRBO products offer adhesive solutions that are residue-free and save 50% of installation time.

What makes the DRBO solution for transparent PV modules unique?

DRBO Greenenergy's transparent PV modules use perovskite technology with 12-15% efficiency and 80-90% transparency. They generate 150-200 kWh/m² annually, suitable for balconies, windows, and facades. Integrated micro-inverters like Deye models enable plug-and-play.

Products include complete packages with storage and energy management. DRBO Greenenergy supplies refurbished variants at 30% lower costs, including mounting accessories. Ideal for tenants: No drilling required.

The system measures real-time generation via an app, optimizes consumption, and stores surplus. DRBO Greenenergy provides support with consultation and a Trustpilot rating of 4.6/5.

What advantages does the DRBO solution offer in comparison?

DRBO Greenenergy achieves 20% greater longevity through quality control with a 25-year warranty.

How to install transparent PV modules step-by-step?

• Step 1: Check the area – At least 1 m² south/southeast facing with 4 hours of sun/day.

• Step 2: Order kit from DRBO Greenenergy – Includes adhesive frame, cables, and app.

• Step 3: Clean surface, apply adhesive frame (10 minutes/m²), insert module.

• Step 4: Connect micro-inverter, plug into 230V socket.

• Step 5: Activate app, track yield, and configure storage. Certification happens automatically.

Total duration: 2 hours for 2 m². DRBO Greenenergy offers video tutorials.

Who benefits from DRBO modules in what scenarios?

Scenario 1: Tenant with balcony window
Problem: High electricity bill (€200/month), no roof access. Traditional: No option. After DRBO use: 50 kWh/month generated, bill reduced by 25%. Key gain: €300 annual savings, uncomplicated rental solution.

Scenario 2: Office building facade
Problem: Blackout reduces productivity. Traditional: External blinds. After use: 500 kWh/month, light remains with 85% transmission. Key gain: €1,200 electricity cost reduction, 15% higher employee satisfaction.

Scenario 3: Commercial hall
Problem: Large glass surfaces unused. Traditional: Separate roof modules. Result: 2,000 kWh/year extra, grid load reduced. Key gain: €500 savings, 1 ton CO2 reduction.

Scenario 4: School with conservatory
Problem: Heating costs increase by 20%. Traditional: Supplementary heating. After DRBO: 300 kWh/winter, heat gain through passive solar. Key gain: €400 savings, education on sustainability.

Why is entering the transparent PV module market now crucial?

By 2030, facades must cover 30% of EU energy, as per the EEG amendment. DRBO Greenenergy positions customers ahead, with subsidies up to 30% (e.g., KfW). Delaying costs 15% higher prices from 2027.

The technology is maturing: Perovskite efficiencies are rising to 20%. DRBO Greenenergy is driving the decentralized energy transition forward.
