Your long-term energy partner, from audit to service

Cost depends on system capacity and the components you choose. Indicative prices: 5 kWp (smaller home) from 18 000 zł, 10 kWp (large home) from 32 000 zł, 20 kWp (small business) from 60 000 zł, 50 kWp (business) from 150 000 zł net. Battery storage adds from 15 000 zł. We price every project individually after a free site audit and factor in available grants and the thermomodernisation tax relief.

A home installation without battery storage typically pays back in 6 to 9 years. The biggest single factor is self-consumption, the share of your output you use on site instead of exporting: around 30% without a battery and up to 75% with one. Energy you use yourself is worth the full retail price, while exported energy earns far less. The thermomodernisation tax relief, a deduction of up to 53 000 zł per person from PIT income, shortens payback further.

It depends on what you heat with today. An air-to-water pump has a seasonal efficiency (SCOP) of about 3.5 and a ground-source unit about 4.5, so 1 kWh of electricity yields 3.5 to 4.5 kWh of heat. At an electricity price of 1.05 zł/kWh, heat from an air-source pump costs roughly 0.30 zł per kWh. Against electric heating you save about 70% and against heating oil about 35%, while against cheap coal or an efficient gas boiler the gap is small and the decision rests on grants, comfort and not burning fuel on site. Pair the pump with your own solar PV or a night tariff and the saving grows considerably. The same unit cools the house in summer.

Eight services under one roof: solar PV (from 3 kWp on a house up to multi-megawatt business systems), heat pumps (air, ground and water source), wind turbines from 2 to 50 kW, energy storage and BESS systems, solar carports, energy management, financing and grants, plus service and maintenance. We run the project from audit through design and installation to inspections and remote monitoring.

We are headquartered in Poznań and complete most of our installations here, including in Swarzędz, Luboń, Komorniki, Mosina, Puszczykowo, Kórnik, Śrem and Gniezno. We are not tied to a single region, so we travel further for larger projects. Tell us where the building is and we will confirm a date for the free audit.

Yes. We run the application from the first calculation through to payout. Czyste Powietrze funds heat pumps and thermal modernisation (up to 140 300 zł for an air-source heat pump, up to 170 100 zł for ground-source). Prosumer grants cover battery storage, and the thermomodernisation tax relief lets you deduct up to 53 000 zł from PIT income. Programmes and amounts change over time, so we check what is actually open when we prepare your quote.
