Solar Battery Rebate Massachusetts: Complete Guide for 2026
Home batteries are becoming essential for solar owners and anyone wanting backup power. Here's how to get the most from Massachusetts solar battery incentives—including programs that pay you every year just for owning a battery.
Key Takeaways
- Federal 30% tax credit covers batteries charged from solar
- ConnectedSolutions pays $225-$275/kWh annually—a 10 kWh battery earns $2,500+/year
- SMART program offers additional incentives for batteries paired with solar
- Combined incentives can offset 50-70% of battery costs over time
Looking for a solar battery rebate in Massachusetts? While the state doesn't offer a traditional upfront rebate, it has something potentially better: programs that pay you year after year for owning a battery.
Between the federal 30% tax credit, ConnectedSolutions annual payments, and SMART program incentives, Massachusetts homeowners can recover a significant portion of their battery investment—often while enjoying backup power and lower electricity bills.
Massachusetts Solar Battery Incentives Overview
Here's a summary of every solar battery rebate and incentive available to Massachusetts homeowners in 2026:
2026 Battery Storage Incentives
| Program | Amount | Type | Notes |
|---|---|---|---|
| Federal Tax Credit (25D) | 30% of total cost | One-time | Must be charged from solar/renewable |
| ConnectedSolutions | $225-$275/kWh/year | Annual | Demand response participation required |

| MA State Tax Credit | 15% up to $1,000 | One-time | For solar installations |
ConnectedSolutions: Get Paid to Own a Battery
ConnectedSolutions is Massachusetts' flagship battery incentive program, and it's one of the best in the country. Here's how it works:
You enroll your battery in a "demand response" program. During peak electricity demand (hot summer afternoons, typically), your utility sends a signal asking your battery to discharge to the grid. In exchange, you receive annual payments based on your battery's capacity.
What You Get
- $225-$275/kWh annually (varies by utility)
- 10 kWh battery = $2,250-$2,750/year
- 5-year payback on battery investment is possible
What's Required
- Compatible battery (Tesla, Enphase, LG, etc.)
- Participate in 30-60 demand events per summer
- Eversource, National Grid, or Cape Light Compact customer
Important: You Keep Backup Power
During demand response events, your battery discharges but you can set a reserve (typically 20-30%) to ensure you still have backup power. You won't be left without protection during an outage.
Federal 30% Tax Credit for Batteries
The Residential Clean Energy Credit (Section 25D) provides a 30% tax credit for battery storage systems—but with an important requirement: the battery must be charged primarily (80%+) from renewable sources like solar.
This means if you're adding a battery to an existing solar system or installing both together, you qualify. Standalone batteries charged from the grid generally don't qualify for the federal credit.
Key Details
- Credit amount: 30% of total installed cost (no cap)
- Requirement: Must be charged 80%+ from renewable sources
- Minimum capacity: 3 kWh
- Applies to: Equipment and installation costs
- How to claim: IRS Form 5695 when filing taxes
Unlike 25C, No Annual Cap
The 25D credit for solar and batteries has no annual dollar limit. A $15,000 battery system gets a $4,500 credit. This is different from the 25C credit for heat pumps and insulation, which has annual caps.
SMART Program Battery Adders
Massachusetts' Solar Massachusetts Renewable Target (SMART) program provides ongoing incentive payments for solar installations. If you add battery storage to a SMART-qualified solar system, you may receive additional "adder" payments.
The exact amount varies by utility territory and changes over time as the program evolves. Contact your solar installer to determine current SMART battery adder rates in your area.
Stacking Example: Real Savings on a Tesla Powerwall
Here's what the numbers look like for a typical Massachusetts battery installation:
Tesla Powerwall 3 (13.5 kWh) Example
* This example shows the battery could pay for itself and generate profit within 5 years through ConnectedSolutions alone, not counting electricity bill savings or backup power value.

How to Get Started
Get Solar + Battery Quotes
Contact 2-3 solar installers and specifically ask about ConnectedSolutions-compatible batteries. Make sure they're familiar with Massachusetts incentive programs.
Verify Incentive Eligibility
Confirm your utility (Eversource, National Grid, Cape Light Compact) participates in ConnectedSolutions and check current payment rates.
Install & Enroll
After installation, your installer typically handles ConnectedSolutions enrollment. Enrollment must happen before the program season starts (usually June).
Claim Your Federal Credit
When you file your taxes, use IRS Form 5695 to claim the 30% Residential Clean Energy Credit. Keep all invoices and documentation.
The Bottom Line
Massachusetts may not have a traditional upfront solar battery rebate, but the combination of ConnectedSolutions payments and the federal tax credit makes battery storage highly attractive. With ConnectedSolutions alone, a 10+ kWh battery can pay for itself within 4-6 years.
Add in the backup power security, electricity bill savings, and potential SMART program adders, and batteries are becoming an increasingly smart investment for Massachusetts solar owners.

Frequently Asked Questions
Is there a solar battery rebate in Massachusetts?
Yes. Massachusetts offers multiple solar battery incentives: the ConnectedSolutions program pays $225-$275/kWh annually for participating in demand response, the SMART program provides ongoing incentive payments, and the federal 30% tax credit applies to battery storage. Combined, these can offset 50-70% of battery costs.
How much does a solar battery cost in Massachusetts?
A typical home solar battery (10-15 kWh capacity) costs $10,000-$20,000 installed in Massachusetts. After the federal 30% tax credit and state incentives like ConnectedSolutions, your net cost can drop to $5,000-$12,000 depending on the battery size and incentives you qualify for.
Can I get a battery rebate without solar panels?
Yes, but with limitations. The federal 30% tax credit requires the battery to be charged primarily from renewable sources (solar, wind). However, Massachusetts ConnectedSolutions payments are available regardless of whether you have solar, as long as you participate in demand response events.
What is ConnectedSolutions and how does it work?
ConnectedSolutions is a demand response program where utilities pay you to discharge your battery during peak demand events (typically 30-60 events per summer). You receive $225-$275 per kWh of battery capacity annually. A 10 kWh battery could earn $2,250-$2,750 per year.
How long do solar batteries last?
Most solar batteries are warrantied for 10 years or a certain number of cycles (typically 4,000-6,000). With proper use, many batteries last 15+ years. The Tesla Powerwall, LG RESU, and Enphase IQ batteries are popular choices in Massachusetts with strong warranties.
