PVKalkulator

Calculate how much energy your photovoltaic system will produce, when the investment will pay off, and how the energy storage affects the system's operation. Check the impact of the energy storage on the self-consumption of energy from the panels. The PV calculator allows you to estimate the annual energy production from a photovoltaic system for a given location, using local solar conditions. It calculates the approximate profit and simple payback period, assuming net-billing based on actual hourly energy prices from August 1, 2024, to July 31, 2025. The calculation algorithm simulates the operation of the system with the energy storage throughout the year with a 1-hour time step. The energy storage simulation does not take into account additional optimization for energy prices – energy from the storage is used as needed.

The application works for coordinates within Poland.

What makes the PVKalkulator app stand out?
- Simple interface: provide a few key details, and the application performs the calculations.
- The application simulates the operation of the system throughout the year with a 1-hour time step.
- Indicates the impact of energy storage on self-consumption.
- The simple payback time is estimated based on actual hourly (archived) energy prices.
- Takes into account current photovoltaic billing conditions in the net-billing system.
