What is the off-grid solar panel system calculator?

The Off-Grid Solar Panel System Calculator helps you size the battery bank, watts of solar panels and the solar charge controller you need. The calculator assumes you will need to size your system to get you through average amount of sun-light in the least sunniest month of the year for your location.

How do I set up an off-grid Solar System?

Step 1 – Add Your Appliances - The calculator is pre-populated with common off-grid appliances. Add, edit and remove appliances as needed Step 2 – Enter Sun Hours - See map below to find your zone Step 3 – Review Results - Battery Bank Amp Hours and Required PV Array will show your requirements

What components do I need for an off-grid Solar System?

Below is a combination of multiple calculators that consider these variables and allow you to size the essential components for your off-grid solar system: The solar array. The battery bank. The solar charge controller. The power inverter. Simply follow the steps and instructions provided below.

Which data source should a solar battery bank be based on?

Data source: NREL (National Renewable Energy Laboratory), as per NREL's terms. In the absence of backup power sources like the grid or a generator, the battery bank should have enough energy capacity (measured in Watt-hours) to sustain operation for several days during periods of low input from the solar array.

How do I set up solar panels?

Select the nominal voltage of your battery bank. Select the lowest temperature that you expect your solar panels to be exposed to in daylight. Enter the number of solar panels wired in series. If you have multiple strings in parallel, enter the number of series-wired solar panels in each string.
