Funding for commercial PV systems 2026

KfW loans, EEG compensation and regional subsidies at a glance

What funding is available for commercial PV systems? Commercial businesses can benefit from low-interest KfW loans (KfW 270), EEG feed-in tariff and regional funding programs. Additionally, there are sometimes special subsidies for battery storage. The combination of several funding programs is often possible.

KfW Loan 270: Renewable Energy – Standard

The KfW loan 270 is the most important financing instrument for commercial PV systems. It offers low-interest financing for photovoltaic systems and battery storage.

Konditionen KfW 270

  • Zinssatz: ab 1.00% effective p.a. (depending on creditworthiness)
  • Kreditbetrag: up to 50 million € per project
  • Laufzeit: 5, 10 or 20 years
  • Tilgungsfreie Anlaufjahre: 1-3 years possible

The application is submitted through your house bank. The bank checks creditworthiness and forwards the application to KfW. Important: The application must be submitted BEFORE starting the measure.

EEG feed-in tariff

For electricity fed into the grid you receive a guaranteed compensation for 20 years. The amount depends on system size and commissioning date.

Dachanlagen bis 40 kWp

~8.1 cents/kWh

pro kWh eingespeist

Dachanlagen 40-750 kWp

~7.1 cents/kWh

pro kWh eingespeist

The compensation rates are adjusted quarterly (degression). For commercial systems, high self-consumption combined with partial feed-in is usually worthwhile.

Regional funding programs

In addition to federal programs, there are regional subsidies that vary by location:

Schleswig-Holstein

Schleswig-Holstein offers subsidies for battery storage and innovative energy concepts through the Investment Bank Schleswig-Holstein (IB.SH).

Hamburg

Hamburg subsidizes PV systems and storage through the 'Companies for Resource Protection' program with up to 40% subsidy.

Niedersachsen

Lower Saxony supports commercial energy efficiency measures including PV systems through NBank.

Funding for battery storage

Battery storage is often funded separately, as they increase self-consumption and contribute to grid stability.

Many federal states offer special storage programs with subsidies of 200-500 €/kWh storage capacity. The KfW loan 270 can also be used for storage. Find out about current programs in your region.
