Actual costs, tariffs, net-metering rules, and incentives vary by utility and change over time — confirm with a local installer or energy authority before making decisions.
How solar billing works in Aruba
Exported energy spins your meter back, offsetting what you draw later.
In Aruba, rooftop solar is often compensated through an arrangement that resembles net metering, where the electricity you send to the grid is typically credited against the electricity you draw from it. In many areas only the net difference at the end of a billing period is charged, so surplus generation in sunny months may help cover quieter ones. The exact crediting rules, billing windows, and any caps vary by region and utility and should be confirmed locally.
