Net-billing is the settlement system in force in Poland since 1 April 2022 for new prosumers. Energy fed into the grid is sold at the exchange price (RCE) and energy bought from the grid is paid at the tariff price. To make the system profitable, maximising self-consumption is key, hence the popularity of energy storage.

Does photovoltaics work in winter and under cloud cover?

Yes, the installation works all year round. Panels produce energy even under a cloudy sky and in low temperatures. In winter panel efficiency is actually higher thanks to the lower cell temperature. Typically the installation produces 20-30% of its annual yield in winter and 50-60% in summer.

How long does a photovoltaic installation last?

The lifespan of photovoltaic panels is typically 25-30 years, with a warranty of at least 80-87% of nominal power retained after 25 years. Inverters: 10-15 years. LiFePO4 energy storage: at least 6000 charge cycles (15-20 years). The investment pays back in 5-10 years and then generates clean profit for another 15-20 years.

Q: How long does a photovoltaic installation take?

Installing a typical single-family home system takes 1-2 working days. The whole process from signing the contract to commissioning takes on average 4-6 weeks, including design, DSO approvals and fitting a bi-directional meter. Industrial installations above 50 kWp are delivered in 6-12 weeks.

Q: Are permits required for photovoltaics?

For micro-installations up to 50 kWp a notification to the OSD (Distribution System Operator) is enough, no building permit is required. We handle the entire formal process. For installations above 50 kWp additional industry approvals are required.

Q: How long is the warranty on a photovoltaic installation?

Solplanet inverters and energy storage come with a 10-year manufacturer warranty. Photovoltaic panels have 12-15 years of product warranty and 25-30 years of performance warranty. The installation warranty is 5 years, extendable. Industrial BESS storage: 5 years, extendable to 10 years.

More and more companies are investing in their own photovoltaic installation. Cut your bills, use free energy from the sun during peak demand hours and secure your production processes. The installation works for decades, generating steady savings and a fast return on investment.

Return on investment and ESG

Real financial gain and a competitive edge.

Photovoltaics for business is not a cost but an investment that lowers operating expenses and strengthens your market position.

Installation economics

25–30 years

Installation lifespan

Low running costs and a long lifespan. The installation pays back quickly and then generates clean profit.

Self-consumption

The key to profitability

Under net-billing, what counts is the ongoing use of your own energy. BESS storage and an EMS system maximise self-consumption.

Support for your sustainability strategy

Using renewable energy has a positive impact on your brand image and opens up new business opportunities.

Frequently asked questions

Everything worth knowing before you invest in photovoltaics.

How much does a photovoltaic installation cost?

The price depends on the installation capacity, the type of panels and inverter, the roof type and whether it works with energy storage. A typical home installation of 6–10 kWp costs from around PLN 25,000 to 50,000 gross.

After the Mój Prąd grant and the thermal modernisation tax relief, the net cost can be significantly lower. For a business we prepare the quote individually based on the consumption profile.

How long does the installation take?

Installing a typical single-family home system takes 1–2 working days. The whole process from contract to commissioning takes on average 4–6 weeks, including design, DSO approvals and fitting a bi-directional meter.

Industrial installations above 50 kWp are delivered in 6–12 weeks, depending on the scope and structure.

Are permits required?

For micro-installations up to 50 kWp a notification to the OSD is enough, no building permit is required. We handle the entire formal process.

For installations above 50 kWp additional industry approvals are required, which our design department takes care of.

How long is the warranty?

Solplanet inverters and energy storage come with a 10-year manufacturer warranty. Panels have 12–15 years of product warranty and 25–30 years of performance warranty.

The installation warranty is 5 years, extendable. Industrial BESS storage: 5 years, extendable to 10 years.
