13 | Enter a city name. If you get an error it's likely your location couldn't be found. Try selecting a different weather dataset below or a different location above. | Double-click the yellow cells above for a pop-up calendar or enter dates manually in the format shown. The year does not matter but both dates must be in the same year. | Enter the STC rating of your solar panel(s) in DC watts (Wp) | Click the arrow to enter either Wh usage or daily range. The other will be calculated below. | Wire/connection ohmic losses, diodes, charge controller efficiency, system availability, etc. | Enter your best estimate: trees, buildings, cars, terrain, self-shading, etc. | Set this to 0% if your array is tilted while moving. | Estimate the amount of travel in each direction. You will rarely travel in a straight line all day. Set both to 0% if your array does not tilt when moving. | Assumes 2-axis tracking by manually orienting the solar array. | ||||||||
