What was my energy worth on the market?

Enter a month, your county and system, and how much you injected. We value it three ways: at the hour it was injected (day-ahead market), at the month's average PZU price (what most contracts settle at), and what your supplier credited.

How we calculate

Production shape: PVGIS (JRC) gives the hourly output of a 1 kWp system at your county's centroid for the chosen tilt and orientation; we normalise each calendar month into a 24-hour profile and assume injection follows it.

Value A = Σ over hours of (injected kWh × hourly share × the month's average day-ahead price for that hour), in lei/kWh converted with the exchange rate of each delivery day.

Value B = injected kWh × the month's average day-ahead price. Value C = the amount you enter, or the supplier's published settlement rule applied to B.

Limits: self-consumption is assumed flat across the day; weather of the actual month is not modelled; supplier rules are summarised from public sources and marked 'to verify' when unclear.

This is an estimate for orientation, not an audit of your bill. Check your contract for the exact settlement terms.
