Want to Add a battery?

Rising electricity costs and increasing outages affect homes across the U.S. A home battery lets you store energy for when you need it most—reducing peak-time bills, providing seamless backup during blackouts, or both. Whether adding to existing solar, going full solar + battery, or starting with battery-only—we match you with the best battery and components to fit your needs.  We may even be able to connect you to a certified installer in your area.

Quick Benefits

• Lower Peak Bills — Store low-cost energy (off-peak grid or solar) and use it during expensive high-demand periods—common with time-of-use (TOU) rates in many states.
• Reliable Backup Power — Keep essentials (or your whole home) running during outages, storms, or grid issues—anywhere in the country.
• Flexible for Any Setup — Easy retrofit to most existing solar systems, or build a complete solution from scratch.
• Potential Incentives — State, utility, and local rebates/tax credits available in many areas (e.g., California’s SGIP program offers up to $1,100/kWh for qualifying homes under Residential Solar and Storage Equity categories)—we’ll help check what’s available for your location.
• Expert, No-Pressure Guidance — Share your details, and our team will  match you with the correct products and perhaps some local pros for the installation (if needed). 

Why Batteries Are a Smart Move Nationwide

Electricity prices are climbing across the U.S. (recent forecasts show residential prices rising to around 17.9–18.05 cents/kWh in 2026, with continued increases expected). Many utilities now use time-of-use (TOU) rates, charging more during peak hours (often afternoons/evenings) to manage grid load.

A battery helps:

• Peak Shaving / TOU Savings — Charge when rates are low, discharge during peaks—potential savings of hundreds to thousands annually, depending on your utility and usage.
• Backup Power — Automatic switchover for essentials or whole-home during outages—valuable in any storm-prone, wildfire, or grid-challenged area.
• Combo Approach — Get both resilience and bill reduction.

Incentives vary by state/utility:

• California example: The Self-Generation Incentive Program (SGIP) provides strong rebates for battery storage—up to $1,100/kWh under Residential Solar and Storage Equity (for low-income, disadvantaged communities, medically vulnerable, or high-fire/PSPS-affected homes), with other categories like Equity Resiliency around $1,000/kWh historically. These can cover a large portion (or nearly all) of costs in qualifying cases, though waitlists are common in many territories (PG&E, SCE, SDG&E).
• Other states: Similar programs exist elsewhere—rebates (e.g., in CT, MA), tax credits (e.g., NY up to $5,000), or utility incentives (e.g., TX, CO exemptions). Submit your details for a personalized check in your area.

No federal tax credit for new installs in 2026, but local options can still make projects very affordable.

Tailored to Your Priorities

Whole Home vs. Partial Home (Essentials):

• Whole-home: Covers appliances, AC, EV charging—ideal for full independence.
• Partial/essentials: Focuses on fridge, lights, medical devices, WiFi—often more cost-effective for typical outages.

Sizing & Compatibility: In the form below, describe your current setup (if any) and goals—we’ll help evaluate needs like capacity (e.g., 10–15+ kWh common for good coverage) and options that fit your utility.

Sun Supply PV provides leading batteries for retrofits or new installs—we can also create plans for your solar building permits.
