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 TSh237/kWh in Tanzania. Local incentives may reduce the upfront cost — check current subsidy, tax-credit, or VAT programs in Tanzania, 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 Tanzania. 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 Tanzania

Self-consumption only

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

In Tanzania, 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.

Do you get paid for exporting solar energy in Tanzania?

Where solar value comes mainly from self-consumption, the savings in Tanzania 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.
