Massachusetts has the highest electric rates in the continental US and the strongest state solar incentives. Even without the expired federal ITC, payback is 8.5–9.6 years. Here is what solar actually costs in 2026.
Yes — even without the federal tax credit. Massachusetts has the highest residential electric rates in the continental US (~$0.33/kWh) and the strongest state incentive stack: SMART 3.0 pays $0.03/kWh for 20 years, 1:1 net metering credits your full retail rate, and ConnectedSolutions pays $225–$275/kW annually for battery storage. A 10 kW system pays for itself in about 9 years and saves $60,000–$80,000 over 25 years. No other state combines this level of electric rates with this depth of state incentives.
Prices based on Hyundai 440W panels (best value) at current MA market rates. The Section 25D federal tax credit is $0 for cash/loan purchases in 2026.
| System Size | Panels | Gross Cost | SMART/yr | SMART (20yr) | Net Cost* | Payback |
|---|---|---|---|---|---|---|
| 6 kW | 14 | $19,560 | $216 | $4,320 | $14,240 | 8.5 yr |
| 8 kW | 18 | $25,280 | $288 | $5,760 | $18,520 | 8.8 yr |
| 10 kW | 23 | $30,800 | $360 | $7,200 | $22,600 | 9.1 yr |
| 12 kW | 27 | $36,720 | $432 | $8,640 | $27,080 | 9.4 yr |
| 14 kW | 32 | $43,120 | $504 | $10,080 | $32,040 | 9.6 yr |
*Net cost = gross cost minus SMART 20-year income, state tax credit ($1,000), and sales tax exemption (~$1,925). Does not include net metering savings or ConnectedSolutions battery revenue, which further reduce effective cost. Federal 25D ITC = $0. Prices reflect Hyundai 440W at $3.09/W average.
Six state-level incentives that stack together. This is why Massachusetts remains one of the best states for solar even after the federal ITC expired.
Performance-based income paid monthly. Locks in at enrollment.
Excess energy credits roll month-to-month. Annual true-up.
Summer demand response with Eversource or National Grid. 5-year enrollment.
Claimed on your Massachusetts state income tax return.
Solar adds value to your home but does not increase your property tax assessment.
Solar equipment and installation labor are exempt from MA sales tax.
The Section 25D residential solar tax credit expired December 31, 2025. Any installer still quoting you a 30% federal credit for a purchased system is either uninformed or dishonest. The only path to federal incentives is through a Section 48 lease/PPA, where a third-party system owner claims the commercial ITC and passes savings to you as a lower monthly payment.

N-type TOPCon cells perform well in cold temps and partial shade from snow cover.
“But it snows in Massachusetts.” Yes — and solar panels still deliver exceptional value. Here is why.
Solar panels are semiconductors — they generate electricity more efficiently in cold temperatures. A 40-degree-F day in Massachusetts produces more electricity per hour of sunlight than a 100-degree-F day in Arizona. The temperature coefficient works in New England's favor.
Panels are installed at a 20–40 degree tilt, and their dark glass surface absorbs heat even on cloudy days. Most snow slides off within 1–2 days. Active snow removal is not recommended and can damage panels. The production loss from snow is typically less than 3% annually.
Massachusetts averages 4.5 peak sun hours per day — enough to produce about 1,200 kWh per installed kW per year. A 10 kW system produces ~12,000 kWh/year, which is enough to offset 90–100% of the average MA household's electricity consumption (~10,000 kWh/year).
Your system overproduces in summer and underproduces in winter. Net metering handles this automatically — excess summer credits roll forward to cover winter months. You pay only the minimum monthly charge ($7) year-round. The grid acts as your free battery.
Three ways to go solar. Each has trade-offs. We offer all three and help you choose the one that fits your financial goals.
| Feature | Cash Purchase | Solar Loan | PPA / Solar Lease |
|---|---|---|---|
| Upfront Cost | $30,800 (10 kW) | $0 | $0 |
| Monthly Payment | $0 | $180–$250/mo | Fixed $/kWh rate |
| Federal Credit | $0 (25D expired) | $0 (25D expired) | TPO claims Section 48 |
| System Ownership | You own the system | You own the system | Third-party owns system |
| SMART Income | You receive SMART payments | You receive SMART payments | Typically retained by TPO |
| Net Metering | You keep all credits | You keep all credits | Savings passed via lower rate |
| Best For | Homeowners who want maximum long-term savings and own their equipment outright. | Homeowners who want ownership benefits without paying upfront. | Homeowners who want guaranteed savings with zero ownership responsibility. |
Note on Propel financing: NuWatt's $0 Down Solar (Propel) program is currently available in Maine and Texas only. For Massachusetts, we offer cash purchases, solar loans through multiple lenders, and third-party PPA/lease options. Ask about our current MA financing promotions.

Everything you need to know about solar panels in Massachusetts.
Solar panels in Massachusetts cost $3.00–$3.40 per watt installed in 2026, depending on system size and panel choice. A typical 10 kW system costs $30,800 before state incentives. After the SMART program, state tax credit, and sales/property tax exemptions, the effective net cost is approximately $22,600. The federal 25D residential solar tax credit expired December 31, 2025, so there is no federal credit for cash or loan purchases.
Yes. Massachusetts has the highest residential electric rates in the continental US (~$0.33/kWh average) and the strongest state-level incentive stack in the country. SMART 3.0 pays $0.03/kWh for 20 years, 1:1 net metering credits your full retail rate, ConnectedSolutions pays $225–$275/kW annually for battery storage, and property/sales tax exemptions save thousands more. Payback periods are 8.5–9.6 years even without the federal ITC.
SMART (Solar Massachusetts Renewable Target) 3.0 is a state incentive that pays solar system owners $0.03 per kWh of electricity generated for 20 years. For a 10 kW system producing ~12,000 kWh/year, that is $360/year or $7,200 over the program term. Low-income qualified households receive $0.06/kWh. SMART payments are in addition to net metering savings — they stack together.
We recommend three panel tiers for MA: Silfab 440W (American-made, FEOC-compliant, excellent cold-weather performance), REC 460W (premium efficiency, best for small roofs), and Hyundai 440W (best value with proven N-type TOPCon technology). All three perform well in Massachusetts winters — solar panels actually generate more efficiently in cold temperatures. Snow typically slides off within 1–2 days due to panel tilt and dark surface heating.
Massachusetts offers 1:1 retail rate net metering for residential systems up to 25 kW. When your panels produce more electricity than you use, the excess is sent to the grid and you receive credits at the full retail rate (supply + delivery). Credits roll over month-to-month. At your annual true-up (April for Eversource, March for National Grid/Unitil), any remaining excess is paid out at the avoided-cost rate.
The Section 25D residential solar tax credit expired December 31, 2025. Cash and loan purchases receive $0 in federal credits. However, Section 48/48E (the commercial ITC) is still available through July 4, 2026. Through a solar lease or PPA, a third-party system owner claims the 30% commercial ITC and passes the savings to you as a lower monthly payment. This is the only path to federal incentives for homeowners in 2026.
From signed contract to system activation, the typical timeline is 8–12 weeks. The physical installation usually takes just 1–2 days. The majority of the timeline is permitting (2–4 weeks for municipal approval) and utility interconnection (2–4 weeks for meter swap and PTO). NuWatt handles all permitting, utility paperwork, and SMART enrollment on your behalf.
Yes. Massachusetts averages 4.5 peak sun hours per day annually, and solar panels actually perform more efficiently in cold temperatures than hot ones. Snow slides off tilted panels within 1–2 days (the dark surface absorbs heat even on cloudy days). Net metering banks your excess summer production as credits to use during shorter winter days. A well-sized system will offset 90–100% of your annual electricity usage.
