# Solar Calculator

Use your 12-month average electricity bill or consumption to size the photovoltaic system and, where applicable, its storage capacity.

  **Moldova solar potential:** 1,200–1,400 kWh/m² per year   Instant indicative result

How this estimate is calculated

The estimate is adapted to conditions in the Republic of Moldova. It assumes an annual yield of 1,200 kWh for each 1 kW installed: average monthly consumption × 12 ÷ 1,200, followed by a 25% reserve for mainly daytime use, 30% for balanced use or 50% for mainly evening use. These reserves account for seasonal variation, including lower winter production, orientation and system losses, as well as the net-billing context. The displayed annual energy value applies the selected tariff only up to estimated annual consumption; exported surplus is settled under the applicable net-billing rules and supplier prices, not as a one-for-one kWh offset. Storage is based on average daily consumption: hybrid 15% / 45% / 70%, with a minimum recommended battery of 5 kWh; off-grid 40–50% / 70% / 100%, with a minimum recommended range of 5–10 kWh. Panels are rated at 600 W and measure approximately 2300 × 1150 mm.
