Frequently asked questions

General

Photovoltaic systems provide clean, renewable energy, reduce long-term electricity costs, lower your carbon footprint, and make you less dependent on rising energy prices.

Photovoltaic panels convert sunlight into direct current (DC). An inverter changes this DC into alternating current (AC) for household or business use. Excess electricity can be stored in batteries or fed back into the grid.

Most photovoltaic systems last 25 to 30 years, with a gradual decrease in efficiency over time.

Installation and pricing

Costs vary based on system size and installation type. A typical system for a single-family home in Germany ranges between €5,000 and €15,000, depending on size and components.

Generally, yes, as long as there is sufficient roof space or ground space and adequate sunlight. A professional site assessment is recommended to determine suitability.

On average, you need about 6-8 square meters of roof space per kilowatt peak (kWp). For a typical home, 15-25 square meters are usually required, depending on the system size.

A photovoltaic system can increase the value of your property by reducing energy costs and providing a renewable energy source for future owners.

Excess electricity can be fed into the public grid, for which you receive a feed-in tariff, or stored in a battery system for later use.

Financing

Financing options include bank loans, leasing, solar loans, and Power Purchase Agreements (PPA). These help spread the cost of solar installations over time.

Solar loans offer ownership and control over the system, while leasing or PPA involves monthly payments without direct ownership. Loans can be more cost-effective in the long run, while leasing offers lower upfront costs.

Yes, there are various government incentives and tax benefits in Germany, such as KfW funding programs. Solar investments may also bring tax deductions or depreciation benefits.

Solar financing can increase property value by reducing future energy costs. In some cases, tax advantages such as depreciation and tax credits can be applied.

Business

Solar power can significantly reduce energy costs, protect against fluctuating electricity prices, and provide tax benefits, leading to substantial financial savings for businesses.

Professional installers plan to minimize disruptions. The exact duration and impact depend on the scale of the project, but interruptions are usually minimal.

Roof load capacity, orientation, and available space need to be assessed. Most commercial buildings are well-suited for solar panel systems.

Yes, there are tailored solutions for different industries. Solar installations can be customized to match energy needs, operating hours, and storage capacity.

Commercial installations are typically larger and require more complex planning and financing. They often yield higher returns through greater energy savings and specific tax incentives.
