Step 1: Enter Your LGA
Enter your LGA*, and we’ll look up the the sun hours in your area.
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

Step 3: Calculate Off-Grid System Size
Click the "Calculate My System Size button" and we'll calculate your system size.
Minimum PV
System Size KilowattsAs 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.
