These are approximate figures based on a standardized household consumption of 5,000 kWh/year and an estimated electricity rate of K0.75/kWh in Papua New Guinea. Local incentives may reduce the upfront cost — check current subsidy, tax-credit, or VAT programs in Papua New Guinea, as these can meaningfully shorten the payback period.
Figures are estimates based on typical system assumptions and the latest available electricity-price and billing data for Papua New Guinea. 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 Papua New Guinea
Exports and imports are priced separately, usually at different rates.
In Papua New Guinea, rooftop solar appears to fall under a net-billing-style approach, where the energy you export and the energy you import are typically valued separately rather than simply cancelling out. Exports are often credited at a rate that may be lower than the retail price you pay for imported power, which generally rewards using your own generation as it is produced. The precise export and import prices vary by region and utility and change over time, so they should be confirmed locally.
