Programme profile 270

What is funded?

Photovoltaics & battery storage

Construction, expansion and acquisition of photovoltaic systems, also combined with battery storage. Rooftop and ground-mounted systems.

Solar thermal

Systems for hot-water generation and heating support using solar energy — relevant for existing properties with high energy demand.

Heat pumps & biomass

Air, water and ground-source heat pumps as well as biomass systems — important as part of energy refurbishments.

Micro-CHP and hydropower

Small-scale combined heat and power and small hydropower plants — niche applications with particular funding potential.

KfW 270 terms

Funding amount: up to €150m loan per project — the scope is generous. For private individuals, loan amounts from a few thousand euros are easily possible.

Application route: as with all KfW programmes — apply BEFORE the project begins, through the financing bank, not directly with the KfW.

Combination: KfW 270 can be combined with many other programmes, e.g. with KfW 261 (energy-efficient refurbishment) or with state funding. For tenant-power models, additional funding under the EEG is conceivable.

Strategic value for investors

Photovoltaics on let multi-family buildings is increasingly becoming a standard component of modern investment strategies — for several reasons:

  • Lowering ancillary costs for tenants (higher tenant retention, better lettability)
  • Tenant-power models as an additional revenue stream
  • Contribution to the energy-efficiency class (relevant for sale and valuation)
  • Combinable with KfW 261 for full refurbishments
  • In combination with a heat pump: a significantly higher ESG rating for the property
