1. What is the SGIP Rebate?

The Self-Generation Incentive Program (SGIP) provides rebates for qualifying energy storage systems (batteries) in California. The rebate amount is calculated as a percentage of the battery system cost, typically ranging from 15% to 100% depending on various factors.

2. How Does the Calculator Work?

The calculator uses the SGIP rebate formula:

Where:

• \( \text{Battery Cost} \) — Total cost of the battery storage system in dollars
• \( \text{SGIP Rate} \) — The incentive rate (decimal between 0.15 and 1.0)

Explanation: The rebate amount is simply the battery cost multiplied by the applicable SGIP rate percentage.

3. Importance of Battery Rebates

Details: Battery rebates help offset the upfront costs of energy storage systems, making them more accessible to homeowners and businesses while promoting renewable energy adoption and grid resilience.

4. Using the Calculator

Tips: Enter the total battery system cost in dollars and the applicable SGIP rate (as a decimal between 0.15 and 1.0). The calculator will estimate your potential rebate amount.
