Solar PV System Details: A. in Case of Net Metering

The document summarizes the details of a proposed 7kW solar PV system for a home with either net metering or non-net metering. For net metering, the home consumes around 35 units per day on average. For non-net metering, the system needs 7.3kW total - 4.2kW for daytime load and 2.1kW for battery backup to power a 2-ton AC overnight. The battery specifications include 400Ah capacity at 48V from 8 12V tubular batteries in 2 strings of 4 batteries each.
