Savings minus system cost

These are approximate figures based on a standardized household consumption of 5,000 kWh/year and an estimated electricity rate of $2.61/kWh in Namibia. Local incentives may reduce the upfront cost — check current subsidy, tax-credit, or VAT programs in Namibia, 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 Namibia. 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 Namibia

Self-consumption only

Savings come from using your own power; exports may earn little or nothing.

In Namibia, the main value of rooftop solar appears to come from self-consumption, meaning you save most when you use the electricity your panels produce at the moment it is generated. Energy exported to the grid may earn little or nothing, so systems are often sized and paired with usage habits (or storage) to maximise on-site use. Whether any export compensation exists at all varies by region and utility and should be confirmed locally.

Optimal tilt angle

For Bethanie, the energy-optimal panel tilt is about 28° from horizontal.

Size your system right

For the average household in Namibia, a 1.5 kWp system (3 panels) covers most electricity needs. Use our calculator for a personalized estimate.

Check local incentives

Local incentives may reduce the upfront cost of residential solar — check current subsidy, tax-credit, and VAT programs with your energy authority in Namibia.

Frequently asked questions about solar in Bethanie

How much do solar panels cost in Bethanie?

A typical 1.5 kWp residential solar system in Bethanie, Namibia costs approximately $38,900 before incentives — this is an estimate based on typical regional pricing. Local incentives such as subsidies, tax credits, or VAT exemptions may reduce the upfront cost; check current programs in Namibia.

Do you get paid for exporting solar energy in Namibia?

Where solar value comes mainly from self-consumption, the savings in Namibia typically come from using your own generation rather than from exporting it, and any payment for surplus sent to the grid may be small or absent. Shifting usage to daytime hours or adding battery storage can help you capture more of that value. Because export arrangements vary by region and utility and may change, confirm the current rules with a local installer or energy authority.

How much electricity do solar panels produce in Bethanie?

A 1.5 kWp solar system in Bethanie produces approximately 3,062 kWh per year, based on 5.6 peak sun hours per day and 2,373 kWh/m² annual irradiance.

What is the solar panel payback period in Bethanie?

Based on Namibia's electricity rate of $2.61/kWh, a 1.5 kWp system in Bethanie pays for itself in approximately 10 years before incentives. After that, the electricity it generates is essentially free for the remaining panel lifespan of 25+ years.
