What are solar panels and how do they work?

Solar modules convert sunlight directly into electricity and form the basis for environmentally friendly energy. They consist of interconnected solar cells that convert light into electrical energy. Ideal for balconies, roofs, or open spaces, they enable cost-saving self-production. DRBO Greenenergy offers high-quality modules for easy integration into residential and commercial areas, thus supporting the decentralized energy transition.

How exactly do solar modules work?

Solar modules consist of silicon cells that absorb light and convert it into direct current. An inverter transforms this current into household alternating current. The photovoltaic effect generates voltage when photons hit the cells, while bypass diodes minimize losses due to shading. Modern modules achieve efficiencies of 20–22 percent. DRBO Greenenergy combines solar modules with storage units and bidirectional inverters to ensure maximum self-consumption and efficiency.

What types of solar modules are there?

There are monocrystalline, polycrystalline, and thin-film modules. Monocrystalline modules offer the highest efficiency (20–22%), polycrystalline modules are more cost-effective (15–18%), and thin-film modules are flexible but less efficient (10–13%). DRBO Greenenergy mainly supplies monocrystalline panels, which can be optimally combined with SunLit storage units. Bifacial modules utilize light from both sides, increasing yields by up to 15 percent.

How to choose the right solar module?

The choice depends on the required power, efficiency, mounting area, and budget. Annual yield can be simulated with online calculators. Modules with PID protection prevent power losses. DRBO Greenenergy recommends 400 Wp modules for balconies, which deliver 500–800 kWh per year. Certifications such as IEC 61215 guarantee longevity. Professional advice helps avoid mispurchases and select the optimal system.

Why are solar modules financially worthwhile?

Solar modules pay for themselves in 5–8 years and save €800–1500 annually. Funding programs like KfW loans reduce investment costs. With DRBO Greenenergy storage units, the self-consumption rate increases to up to 70 percent, allowing for long-term savings of €20,000–30,000. Electricity cost savings, inflation protection, and tax advantages further increase profitability.

How to install solar modules correctly?

Installation is ideally done facing south (30–35°) with sufficient wall clearance. Plug-and-play kits are particularly suitable for tenants. Electricians check grid connection and safety. DRBO Greenenergy supplies plug-and-play solar modules with mounting accessories. Shadow analysis via app minimizes yield losses. Permits for systems over 600 Wp must be applied for with the grid operator. Professional installation guarantees long-term efficiency and safety.

What subsidies are available for solar modules?

Subsidies like KfW 270, EEG surcharge, or regional grants reduce costs by up to 30%. Private customers also receive bonuses between €500 and €2000. Programs such as "Solar for Tenants" support balcony power plants, while DRBO Greenenergy advises on applications. Tax depreciation for businesses further reduces investment costs. Funding should be applied for before purchase to receive maximum support.

Frequently Asked Questions

Are solar modules weather resistant?

Yes, they withstand hail up to 25 mm, wind loads up to 2400 Pa, and snow loads. DRBO modules are IP67 certified.

How much electricity does a solar module generate?

400 Wp modules generate 400–500 kWh per year in Germany, depending on location, orientation, and tilt.

Do I need a permit for balcony power plants?

Systems under 600 Wp do not require a permit. For higher capacities, the grid operator must be informed. Tenants should check their lease agreement.

Is a storage unit worthwhile?

Yes, with SunLit storage units from DRBO Greenenergy, the self-consumption rate increases to 70 percent. Amortization is usually around six years.

Can tenants install solar modules?

Absolutely. Plug-and-play balcony power plants are ideal for tenants. DRBO Greenenergy offers complete sets including mounting accessories.
