How do solar energy solutions pay off for private and business customers in Germany?

Article published at: Dec 14, 2025

Solar energy solutions offer numerous advantages to private and business customers, such as significant savings on electricity costs, government grants, and increased energy independence. These systems contribute to reducing CO2 emissions while also increasing property value. Providers like DRBO Greenenergy offer access to state-of-the-art, efficient solar and storage solutions like the SunLit series, which are particularly suitable for private and commercial needs.

What are solar energy solutions and how do they work?

Solar energy solutions consist of photovoltaic systems that convert sunlight into electricity. This electricity is either used directly in the household or business, fed into the grid, or stored in storage systems like the SunLit energy storage units from DRBO Greenenergy. This way, the generated electricity can also be used at night or on cloudy days.

A typical PV system consists of three main components:

  • Solar modules: Convert sunlight into electricity.

  • Inverters: Convert the generated DC power into AC power.

  • Storage solutions: Store electricity for later use.

Such systems can be flexibly adapted to the needs of users and are suitable for both private homes and commercial facilities.

How do solar energy solutions differ for private and business customers?

While private customers usually focus on self-consumption and increasing their energy autonomy, business customers primarily focus on economic efficiency and achieving sustainability goals. DRBO Greenenergy offers tailor-made systems that are optimized for both target groups.

Target Group Focus Typical System Size Advantages
Private Customers Self-consumption, tenant electricity 0.6–10 kWp Lower electricity costs, more independence
Business Customers Energy efficiency, ESG goals 10–500+ kWp Tax depreciation, CO2 reduction

Both groups benefit from tax breaks and shorter amortization periods, making investment in solar energy particularly attractive.

What advantages do solar energy solutions offer in Germany?

Solar energy offers both economic and ecological advantages in Germany:

  • Cost savings: Reduces electricity costs by up to 80%.

  • Energy independence: Protects against rising energy prices.

  • Government funding: Benefit from attractive grants and feed-in tariffs.

  • Sustainability: Solar power contributes to improving the CO2 balance and promotes a green energy future.

By using intelligent energy storage systems like the SunLit energy storage system from DRBO Greenenergy, self-consumption can be optimized, further increasing profitability.

Why is now the best time to switch to solar energy?

Thanks to high electricity prices, falling PV system costs, and government programs like EEG 2023, the conditions for switching to solar energy are currently optimal. DRBO Greenenergy offers easy integration of solar energy with its plug-and-play systems and balcony modules, even for tenants or apartment owners.

Continuously falling investment costs and increasing profitability through self-consumption make switching to solar energy an even more attractive option. These systems typically pay for themselves in 5 to 8 years.

How do you choose the right solar system for your project?

Choosing the right system depends on various factors, such as electricity consumption, available roof space, and budget. Individual consultation by experts is essential here. DRBO Greenenergy offers a wide range:

  • Complete packages: Solar modules, micro-inverters, and storage solutions.

  • Balcony power plants: Compact solutions for small areas.

  • Individually scalable systems for commercial applications.

An integrated energy management system helps monitor consumption and optimize the use of electricity and storage.

What funding programs and tax benefits are available?

In Germany, there are various government grants and tax benefits that facilitate the transition to solar energy:

  • Federal Funding for Efficient Buildings (BEG): Grants for PV systems and storage solutions.

  • KfW loans: Favorable financing options for solar and storage systems.

  • Tax relief: PV systems up to 30 kWp are exempt from VAT.

In addition, local municipal utilities offer bonuses for self-consumption or feeding solar power into the grid.

Funding Type Provider Benefit
BEG BAFA Grant for PV and storage solutions
KfW 270 KfW Favorable loans
VAT Exemption Federal 0% VAT on system costs

How does solar energy contribute to corporate sustainability?

For businesses, solar energy not only offers cost reduction but also contributes to social and environmental responsibility. Companies can reduce their CO2 emissions, achieve ESG goals, and improve their image through the use of green energy. DRBO Greenenergy supports companies in finding tailor-made decarbonization solutions, whether through flat-roof systems or microgrids.

What are the typical costs and returns for solar systems?

The costs for a solar system vary depending on the system size and equipment. On average, the costs for:

  • Private customers: 5–10 kWp at approx. 7,000 to 15,000 euros.

  • Commercial customers: 30–100 kWp at approx. 40,000 to 100,000 euros.

With the integration of storage systems like the SunLit system, the self-consumption rate can be increased to up to 80%, achieving an annual return of 6–10%.

What role does energy storage play for solar projects?

Storage systems are crucial for maximizing self-consumption. They allow electricity generated during the day to be used at night or on cloudy days. DRBO Greenenergy offers the SunLit storage system, a solution that combines high capacities and safe lithium technology. This can double self-consumption, which is particularly beneficial for companies with variable energy demands.

DRBO Greenenergy Expert Opinions

"The energy transition can only succeed if innovative storage and solar solutions are accessible to everyone. DRBO Greenenergy focuses precisely on this: easy installation, fair prices, and sustainable technology. Our SunLit storage series enables private households and businesses to manage energy intelligently and reduce costs in the long term."

How do plug-and-play solar systems differ from traditional PV systems?

Plug-and-play systems are more compact, easier to install, and require no extensive permits. They are particularly suitable for tenants or small households. In contrast, traditional PV systems are larger, require professional installation, but offer higher performance and better integration into the power grid.

DRBO Greenenergy supplies both mini-systems and commercial solutions that meet individual needs.

What does the future of solar energy in Germany look like?

The future of solar energy in Germany will be more decentralized and digital. With advancements in storage technology and smart energy management systems, the use of solar energy will continue to increase. DRBO Greenenergy continuously invests in flexible, scalable systems that meet the needs of both private and business customers.

By 2030, solar power is expected to account for over 30% of Germany's energy mix.

Conclusion

Solar energy is fundamentally changing the German energy market. It offers numerous advantages for both private households and businesses: it reduces costs, protects the climate, and creates independence from rising energy prices. With solutions from DRBO Greenenergy, such as the SunLit storage systems and plug-and-play systems, getting started with solar energy is easy and sustainable for everyone.
