Enter three values about your municipality. See instantly how many kWp you can install on the roofs of public buildings, the gross investment, how much PTJ (Programul Tranziție Justă, Romania's Just Transition Programme, funded by the EU Just Transition Fund) covers, the bill you avoid each year and how many years it takes to pay back the rest. A rough estimate - for an exact assessment, write to us.

Three numbers. An estimate in 5 seconds.
The figures update in real time on the right. Use realistic values for a useful estimate, and check with us for a specific project.
Installable capacity
90 kWp
On the roofs of public buildings, assuming ~0.15 kWp per available m².
Estimated annual production
~108,000 kWh
Based on an average irradiation in Romania of 1,200 kWh/kWp/year. Varies by ±15% depending on orientation.
Estimated gross investment
~€72,000
PV + inverter + cabling + installation, without storage. Average cost ~€800/kWp in 2026 (varies by ±20%).
Public co-financing covered
~€70,560
98% through PTJ in a JTF region. The remaining €1,440 is covered by the community / local budget.
Bill avoided each year
~€22,680
At an average tariff of ~€0.21/kWh (2026, public prices). It comes straight off the municipality's bill.
Payback on the remaining investment
< 1 years
After public co-financing, the remaining part is quickly paid back from the avoided bill.
Note: The estimate uses average values (0.15 kWp/m², 1,200 kWh/kWp/year, €800/kWp installed, €0.21/kWh tariff, 98% PTJ co-financing in JTF regions). For a real project, many variables affect the result: roof orientation, shading, the actual cost under the open EU call, consumption profile, whether or not storage (BESS) is included, the grid tariffs applied.
