Battery Bank Sizing
This calculator will help you size the battery bank for your system.
Step 1
Your Daily Energy Usage
This value is usually printed on your electric bill. Take your monthly kilowatt-hour usage from your electric bill and divide it by 30 to get your daily kilowatt-hour usage. Since it's in kilowatt (1000's of watts) you'll need to multiply that number by 1000 to get the number into watt-hours.
Step 2
How Many Days Should Your System Run without Sun?
How many days of backup power do you want in case of cloudy/rainy days?
(when your solar panels will produce little energy)
Step 3
Adjust the Effective Capacity of Your Battery Bank Due to Low Temperatures
What is the lowest temperature your battery bank will experience?
Results:
Battery Bank Capacity: 0 watt hours
Select a battery bank voltage
Battery Bank Capacity: 0 amp hours
3 String Configuration: 0 amp hours per string
