A simple explanation of a standalone PV system includes:
Solar modules —Provide direct current (DC) power to the battery
Battery bank —Stores electrical energy
Inverter —Converts the DC power stored in the battery to alternating
current (AC)
System Sizing
A PV designer determines the size of the system
based upon customer input and budget. If the system
is too large, you will have excess power seasonally.
If the system is too small, you will run the backup
generator unnecessarily.
PV designers can calculate the size of a system
using the following method:
Calculate how much energy you will need by
determining the average ...
