FREE ENERGY STORAGE! SGIP Rebate for Discover Energy's Batteries

SGIP Rebate in California

Here’s a simple rebate calculation for a residential energy storage system using Discover Energy’s AES RACKMOUNT modules in a Slimline enclosure, paired with the Sol‑Ark 15K inverter—to demonstrate the potential SGIP rebate you can earn.

Typical System Configuration

Let’s assume a 20 kWh battery energy storage system installed with the Sol‑Ark 15K inverter:

• AES RACKMOUNT modules (e.g., 4 × 5.12 kWh modules = approximately 20 kWh)
• Installed by a licensed installer (with permits and inspection)
• Pair the batteries with solar panels to potentially qualify for further SGIP rebates in addition to federal rebates from the Solar Tax Credit (ITC). Check the SGIP portal for information on what incentives are available in your location.

Incentive Rebate Rates under SGIP (2025)

• Standard residential rate: $0.85 per Wh of storage, depending on the incentive step and equity status results in $850 per kWh.
  Solar is not eligible for a rebate at this level.
• Equity-resiliency (low-income or high-fire-threat areas): $1.10 per Wh of storage, which converts to $1,100/kWh for the batteries, and $3.10 for each watt of solar.

Rebate Calculation

The following calculation assumes a 7 kW solar array.

• Standard Tier: $0.85 per watt, or $850/kWh
  Rebate = 20,000 Wh × $0.85 = $17,000
  TOTAL Rebate = $17,000
• Equity-Tier or High-Fire Zone: $1.10 per watt, or $1,100/kWh
  Rebate = 20,000 Wh × $1.10 = $22,000 PLUS 7000 watts x $3.10 = $21,700
  TOTAL Rebate = $43,700

Net System Cost

Batteries + Inverter

Assuming the net cost for equipment (batteries and inverter) is $25,000:

• Standard Tier with $17,000 rebate → the net cost is $8,000
• Equity Tier or High-Fire Zone with $22,000 rebate → the net cost is $3,000

Solar + Batteries + Inverter

Assuming the cost of equipment (solar, batteries, and inverter) is $40,000:

• Standard Tier with $17,000 rebate → the net cost is $23,000
• Equity Tier or High-Fire Zone with $43,700 rebate → the net cost is $0 (FREE!)

Depending on your location, customer status, and the system you install, up to 100% of the system cost could be covered by the SGIP rebate. Any remaining costs for the system could net a further 30% federal rebate under the Solar Tax Credit (ITC).
