Payback of a plant

Enter the power, latitude, tilt and orientation, the plant cost and the tariffs — the calculator estimates the generation, yearly savings and payback time.

How it is calculated

Specific yield is a model for the latitudes of Ukraine and Poland, corrected for tilt and deviation from south; savings — self-consumption at the tariff, the rest at the export price; degradation 0.5 % a year.

The calculation is preliminary. A qualified engineer must check it before installation. Codes: DBN V.1.2-2:2006 (Ukraine) and the Eurocode; for other countries — snow and wind values from the national annex, entered by hand.
