How To Calculate Battery Size For Solar System. Battery sizing is a balancing act. The solar battery calculator applies the best practices for using the depth of dischargeDoD of different types of solar batteries thus ensuring the optimal compromise between the size of the battery bank and the desired long life of the batteries while taking into account their type.
Our battery sizing calculator can help design the perfect solar system for your needs. This is quite an important step to consider when sizing your off-grid solar battery so make sure not to skip it. To figure out how to size your solar system take your daily kWh energy requirement and divide it by your peak sun hours to get the kW output.
No Cost No Obligation.
The first step is to determine the size of your solar array this can be easily determined by collecting 6 months to one year of your utility bills and calculating your average kilowatt hours. Putting the above values into the above calculator the needed battery bank capacity we get back is 1013 AmpHrs. Since batteries are normally at 12V we need 2 batteries at 1095 Ah. This kind of system has no connection to the utility grid.
