Provides gross income tax deduction for costs of purchasing and installing battery backups for certain home solar electrical generators.

This bill allows New Jersey homeowners with solar generators in their primary residence to deduct up to $10,000 of the cost for purchasing and installing battery backup systems from their gross income tax. It directly affects homeowners who have installed solar panels and wish to add energy storage. The key provision creates a tax deduction for these specific battery backup costs, effective immediately for taxable years ending after enactment. The purpose is to incentivize battery storage so solar-powered homes can maintain electricity during power outages, as solar systems currently disconnect from the grid during outages.
