System Parameters

Define your proposed solar and storage system, or size solar from the available roof area

Available roof area (m²) Leave the PV capacity blank to derive it from the roof area. The public calculator assumes 70% of the roof is usable.

Usable roof share (%) Default public assumption is 70%. Adjust this if the roof has more or less usable space after access paths and obstructions.

Planned solar PV capacity (kWp) Optional — enter a manual PV capacity, or leave it blank and let the calculator derive it from the roof area.

Planned battery capacity (kWh) Optional — leave blank if unsure

Planned battery power (kW) Optional — leave blank if unsure

Estimated investment (RM) Optional — leave blank if unsure
