Solar production calculator
Solar panel output for any location.
Enter a site and a system size for a year-one estimate: annual and monthly AC energy, specific yield and capacity factor, from NLR PVWatts v8 on typical-year solar data, anywhere in the world. The array faces the equator unless you change it.
System & site
Type a city, a postal code, or coordinates such as 64.15 N, 21.94 W; then choose a match.
Facing south (180°; 0° north, 90° east, 180° south, 270° west).
Resolve a location above to enable the estimate. Tilt defaults to your site latitude.
Pick a location and system size, then run the estimate to see annual and monthly output.
Estimates come from NLR PVWatts v8 (formerly NREL), which uses NSRDB solar data in the U.S. and an international resource dataset elsewhere — so production figures are available worldwide. Output depends on tilt, azimuth, array type, and assumed system losses; treat results as a year-1 design estimate, not a guarantee.
