Solar panel payback 2026 — Belarus: calculator

Calculated in Belarusian roubles. By default the electricity price is the single-rate household tariff of 0.3037 BYN per kWh (Council of Ministers Resolution No. 93 of 25 February 2026, from 1 March 2026), and the yield is 1,076 kWh per kWp a year (World Bank, Belarus average). The default cost of 3,000 BYN per kWp is only an example — enter the installer's quote.

System size, kWp Peak power of all panels together, from the quote or the panel label. Installed system cost, BYN Total from the installer's quote. 0 — the example price per kWp for the country (see the note above the form) × the size. Used at home, % of production The share you consume while the panels generate. A battery or daytime use raises it. Electricity price per kWh, BYN From your bill. 0 — the country's official average household tariff (named above the form). Price paid for exported power per kWh, BYN What your supplier pays for each kWh sent to the grid. 0 — the surplus is not paid.

How it is calculated

Production in the first year = size (kWp) × specific yield (kWh per kWp a year). The yield is the country average of the World Bank Global Photovoltaic Power Potential study (PVOUT, kWh/kWp/day × 365). It describes well-oriented, optimally tilted panels: a shaded or steep roof, or one facing east or west, produces less.

Saving a year = production × (self-consumption % × electricity price + (1 − self-consumption %) × export price). Power you use while the panels generate replaces power bought at the full tariff; the surplus is sent to the grid and earns the export price (0 if nobody pays for it).

Simple payback = cost ÷ first-year saving, without interest or tariff changes. Net saving over 25 years = the sum of 25 yearly savings, each 0.5% lower than the previous one (an assumed panel degradation), minus the cost. Maintenance, inverter replacement, financing and subsidies are not included — subtract a subsidy from the cost yourself.

Frequently asked questions

Which electricity tariff does the calculator use for Belarus?

0.3037 BYN per kWh — the single-rate tariff for the population in item 5.1 of Annex 2 to Council of Ministers Resolution No. 93 of 25 February 2026, in force from 1 March 2026. Homes with electric stoves pay 0.2581 BYN per kWh (item 1.1), and there are lower rates for electric heating — enter your own tariff in the price field.

How much does a solar panel produce in Belarus?

On average about 1,076 kWh a year per kWp of optimally tilted panels (World Bank Global Photovoltaic Power Potential study: 2.95 kWh per kWp a day).

How is the payback period calculated?

Cost of the system divided by the saving in the first year. It is a simple estimate: it ignores interest on the money, future tariff changes and the slow loss of panel output.
