Benefits for the installer and investor

ROI for the C&I sector: A 30–100 kWp rooftop installation in a self-consumption model (70–85% on-site consumption) allows for an SPBT of 4–6 years. This series of inverters is designed for such operating profiles – with high efficiency at partial load.

Savings: reduction of energy bills by 40–70% per month, limitation of contractual power thanks to operation with an APX battery, zero export function, protection against rising distribution fees and capacity charges.

After-sales support: assistance in configuring zero export, selection of a Smart Meter, parameterization of Q(U)/P(f) curves to meet OSD requirements, remote training for service technicians, Polish-language technical support line.

For the investor: tax depreciation, available subsidies (Energia Plus, Mój Prąd for business in selected editions), VAT invoice, flexible forms of financing – leasing, rental, PPA.

Installation and commissioning

C&I installation is performed by a licensed electrician SEP E up to 1 kV, experienced in PV systems. Process: application for connection conditions to the DSO (16 days to issue conditions), connection agreement, installation (1–3 days for 30–100 kWp), notification and first connection by the power company. Time from order to commissioning: 4–10 weeks. PVGroup.pl helps in preparing application documentation and selecting operating parameters to meet the requirements of the distribution network operator.
