Welcome
to the Alternative Energy Store Off Grid Calculator.
This calculator is designed to help you size a system for off-grid
use.
Start by filling out
the first section, titled Solar Panels. This section will calculate how many Solar
Panels you need, based upon your load (how much electricity you consume).
Once you've completed this section, move on to the
other sections labeled Charge Controller & Battery Bank.
Feel free to call our Experts at 877-878-4060 and have them help you find the system that fits your needs.
Solar Panel Array Sizing
Determine
the size of the solar panel array you will need.
Step 1:
How many kilowatt-hours
(kwh) does your home/location use per month?
(This value is usually printed on your electric bill. If you
don't have a bill, or don't know your consumption, click on 'load
calculator' at the top of this page
to go through the steps to determine this value.)
kilowatt-hours per month
Is your load (kwh) too high? Don't despair, our Experts can help you find
other solutions that may help.
Step 2:
You need to determine the
minimum number of sun hrs per day during the winter.
or
Manually enter the
minimum sun-hours for your location.

The Charge Controller is used between your solar panel array and your battery bank.
Charge controllers optimize how your batteries are charged and prevent
current from going back through the panels from the batteries during the
night time.
Solar Charge Controller Sizing
This
calculator helps you size the solar charge controller(s) needed for your
system.
Step 2:
Choose the voltage of
your battery bank:

Select the
appliances from this drop down menu. To the right will appear typical wattage
values for the appliance you selected. However, for the most accurate
information look on your appliance to find its wattage rating (or it amperage
rating and then multiply that by its voltage to approximate its wattage).
