Calculate Off-Grid System Size
Step 1: Enter Your City
Enter your City*, and we’ll look up the the sun hours in your area.
Error: The National Renewable Energy Laboratory?s PVWatts Calculator does not have climate data for this location. Please try another location. Or add peak sun hours per day.
Your annual average:
peak sun hours per day Edit Hours
Your monthly averages:
*Must enter address to gather data.
How many Sun Hours a day do you average in the darkest month?
We’ll start by using your winter low sun hours to size your PV array. Keep in mind your exact needs may vary depending on how your system will be used.
Step 2: Fill Out Load Calculator
Fill out the table below to estimate energy usage. We’ve included some common household appliances found in off-grid homes. Try to account for everything, keeping in mind that off-grid homes should use efficient appliances, and the major heating loads (water & air heating) are usually not electric.

Step 3: Calculate Off-Grid System Size
We'll estimate your off-grid system size based on the list of appliances and energy usage that you entered. Keep in mind that this is only an estimate, and there are many factors that can influence system sizing. Please contact us for help designing your project.
Click the "Calculate My System Size button" and we'll calculate your system size.
As mentioned before, this is a very basic system size estimation. It is intended to give you a general idea of what your Off-Grid solar system sizing needs would be. This system size is designed to generate the electricity needed to power the daily loads you entered into the load calculator. There are many other factors unique to your specific location and application that can effect the size off the Off-Grid solar system you need. Factors such as whether this is a seasonal property or full time, shading implications, azimuth & tilt of the solar panels, unaccounted peak load variations, available space in your main service panel (MSP), and that is just to name a few.
