No guarantee. The municipality's guideline is what counts, and budgets are limited.
Roof compass
Ottobrunn funds PV systems (photovoltaics) only on pitched roofs of at least 20° that turn at least 60° from south towards east or west. A plain south roof gets nothing. Turn the compass to your roof.
East (90°): 90° from south towards the east. That meets the rule: 10 % of the investment cost without battery, if the roof is pitched at least 20°.
Your roof South roof
886 kWh per kWp a year, 78 % of a south roof (1,129 kWh).
PVGIS value for Munich (35° pitch), scaled to Ottobrunn’s south yield.
The guideline’s own example (annex): 5 kWp on an east roof at €1,950 per kWp gives a €975 grant. The prices are from 2014.
The guideline dates from 2014; the municipality’s page lists it as a running programme on 2 Nov 2026. The day is our sun model for a clear sky, not a weather forecast. The municipality checks your roof against the site plan and building plan. Without guarantee.
How it works in Ottobrunn
- First an advice talk with the municipality (environment office)
- Apply with site plan (roof direction), building plan (pitch) and quote, before you order; possible from 1 January of the year
- The approval comes in writing; the system must be finished by 1 December of the year you apply, or the grant lapses
- To be paid, hand in invoices and bank transfer receipts; if the invoice is lower than the quote, the grant falls
- First come, first served and only within the budget; once it is used up for the year, approvals resume the next calendar year

With a home battery
With 4,500 kWh used a year, a typical house in Ottobrunn covers about 46 % of it from the panels alone. A battery raises the part from your own roof:
With a 10 kWh battery the house would have needed no power from the grid on 257 days in 2025.

Your roof may differ. As of 2 November 2026.
