2025 is the ideal time to invest in solar energy. Solar panels are more efficient and affordable than ever, while electricity prices continue to rise. Especially with DRBO Greenenergy's innovative storage systems, you can increase your energy independence and save costs in the long term. Even small systems can achieve noticeable savings and contribute to sustainability.
How does a solar panel work?
A solar panel converts sunlight into electricity using photovoltaic cells. The generated electricity can be used directly, stored in DRBO Greenenergy's battery storage systems, or fed into the public grid. Photovoltaic cells absorb light particles, which sets electrons in motion, creating direct current. This is then converted into alternating current by an inverter, making it usable for household appliances.
What are the benefits of buying a solar panel?
Buying a solar panel offers numerous advantages: independence from the power grid, lower energy costs, and a reduction in CO₂ emissions. In addition, buyers benefit from government subsidies and tax breaks. Solar panels typically pay for themselves within 6 to 10 years. With solutions like those from DRBO Greenenergy, households and businesses can reduce their electricity costs by up to 60%.
| Benefit | Description |
|---|---|
| Savings | Reduces electricity costs long-term |
| Sustainability | Lowers CO₂ emissions |
| Eligibility for subsidies | Access to government grants and loans |
| Increased property value | Increases real estate value |
Why is now the right time to buy?
Now is the perfect time to buy a solar panel, as prices are historically low and subsidy programs are particularly attractive. Rising energy prices make investing in solar energy especially sensible. DRBO Greenenergy offers simple and quick installation options with its flexible SunLit storage solutions and plug-and-play systems, ideal for renters and homeowners.
How much does a solar panel cost in Germany?
The costs for solar panels in Germany in 2025 vary between €900 and €1500 per kWp, depending on the performance and quality of the modules. Small balcony systems from DRBO Greenenergy are available from as little as €600, making them a cost-effective option for beginners. For larger systems, such as those required for single-family homes, costs range from €9,000 to €13,000, depending on performance and installation. Additional costs for storage and inverters may apply.
How long does a solar panel last?
The lifespan of a solar panel averages 25 to 30 years. Power loss is minimal, with an annual decrease of about 0.3% to 0.6%. Solar panels from brand manufacturers like DRBO Greenenergy are designed for durability and are made from materials that withstand extreme weather conditions. Regular maintenance and cleaning can further extend the lifespan of the modules.
What subsidies are available for purchasing solar panels?
In Germany, there are numerous subsidy programs, including KfW loans, regional grants, and tax breaks. Since 2023, VAT on solar modules up to 30 kWp has been waived, making entry into solar energy particularly affordable. Additionally, some federal states promote the installation of solar power storage systems, such as DRBO Greenenergy's SunLit series, with attractive premiums.
How much electricity can a solar panel generate?
A solar panel with a capacity of 400 watts generates approximately 350-450 kWh of electricity annually. With optimal orientation and sunlight exposure, larger systems of up to 10 kWp can generate up to 10,000 kWh annually, which can cover the entire electricity needs of a four-person household. With storage systems, such as those from DRBO Greenenergy, self-consumption can be increased, allowing the generated electricity to be used around the clock.
What solar panel size is ideal for your home?
The ideal size depends on your electricity consumption and available roof space. One kWp covers about 5-6 m² and produces around 1,000 kWh of electricity annually. DRBO Greenenergy offers modular systems that allow for expansion, so you can start small and expand later as needed.

What mistakes should you avoid when buying?
Be sure not only to compare prices, but also to consider warranties, certifications, and compatibility with storage systems. A common mistake is choosing the wrong size of solar system. Get support from an expert or a DRBO Greenenergy consultant to ensure optimal performance for your needs.
Can a solar system also be worthwhile for tenants?
Yes, especially balcony power plants and plug-and-play systems offer an ideal solution for tenants. These DRBO Greenenergy systems can be easily connected to an outlet and do not require any structural changes. This allows tenants to benefit from solar energy, reduce their electricity bill, and contribute to the reduction of CO₂ emissions.
What are the most important purchase criteria?
Important criteria when buying a solar panel include module efficiency, warranties, price-performance ratio, storage integration, and provider service. Ensure that the modules offer at least 20% efficiency and have a warranty of over 20 years. DRBO Greenenergy combines high quality with personal advice and fast delivery.
| Purchase Criterion | Recommendation |
|---|---|
| Efficiency | ≥ 20% |
| Warranty | 20–25 years |
| Cost per kWp | €900–1500 |
| Storage Integration | Optional, recommended |
