The average residential solar installation costs $3.05/W across NuWatt’s 9-state service area in March 2026. Prices range from $2.85/W in Pennsylvania to $3.18/W in New Hampshire. With the federal ITC expired, these are cash prices with $0 in federal tax credits. Equipment tier matters: Hyundai entry panels save $0.07/W vs. the Silfab standard, while premium REC panels add $0.19/W.

| State | Avg $/W | Range ($/W) | Avg System | Avg Total Cost |
|---|---|---|---|---|
| Massachusetts(MA) | $3.16 | $2.93 – $3.40 | 8.5 kW | $26,860 |
| Connecticut(CT) | $2.98 | $2.78 – $3.23 | 8.2 kW | $24,436 |
| Rhode Island(RI) | $3.10 | $2.78 – $3.45 | 7.8 kW | $24,180 |

| 9-State Average | $3.05 | $2.46 – $3.66 | 8.5 kW | $25,855 |
Range reflects pricing from 5 kW to 25 kW systems. Smaller systems cost more per watt due to fixed overhead (permitting, engineering, mobilization). Prices exclude battery storage.
NuWatt offers three panel tiers. All systems include Enphase IQ8+ microinverters, IronRidge racking, and full monitoring. The panel tier is the primary pricing variable.
| Tier | Panel | Avg $/W | FEOC | Warranty | Degradation |
|---|---|---|---|---|---|
| Entry | Hyundai 440W | $2.98 | — | 25 years | 0.40%/yr |
| Standard (FEOC) | Silfab 440W | $3.05 | 30 years | 0.30%/yr | |
| Premium | REC 460W | $3.24 | — | 25 years | 0.25%/yr |
Why FEOC matters: The Foreign Entity of Concern (FEOC) designation affects financing options. Silfab panels are manufactured in the USA and comply with FEOC requirements, making them eligible for Propel $0 Down Solar financing. Hyundai and REC panels are excellent products but are not FEOC-compliant, limiting them to cash and loan purchases.
Larger systems cost less per watt due to fixed overhead amortization. This table shows national average pricing at each anchor point (Silfab 440W standard tier).
| System Size | Avg $/W | Panel Count | Total Cost | Typical Home |
|---|---|---|---|---|
| 5 kW | $3.30 | 12 | $16,500 | Small home, 800-1,200 sq ft |
| 8 kW | $3.05 | 19 | $24,400 | Average home, 1,500-2,000 sq ft |
| 10 kW | $2.98 | 23 | $29,800 | Larger home, 2,000-2,500 sq ft |
| 15 kW | $2.90 | 35 | $43,500 | Large home or EV owner |
| 25 kW | $2.81 | 57 | $70,250 | Very large home or small commercial |
Quarterly national average $/W for a standard 8 kW system with Silfab 440W panels. The significant Q1 2026 drop reflects post-ITC market repricing.

Price Trend Visualization ($/W)
Transparency is a core value at NuWatt. Here is exactly how our pricing model works.
We anchor pricing at 4 system sizes (5, 8, 15, 25 kW) for each state, then interpolate linearly between them. This captures the real-world volume discount curve more accurately than a single $/W figure.
Each state has unique anchor prices reflecting local labor rates, permit fees, interconnection costs, and competitive dynamics. Prices are set from actual project data, not national averages.
The Silfab 440W serves as the baseline. Hyundai saves $0.07/W (lower panel cost, same inverter/racking). REC adds $0.19/W (higher efficiency cells, premium manufacturing). Offsets are uniform across states.
Every system has a $5,000 minimum gross profit floor. This ensures NuWatt can deliver quality installation, honor its 25-year warranty, and remain in business long-term. Very small systems (under 4 kW) will see a higher $/W as a result.
Pricing anchors are reviewed monthly against actual project costs, equipment wholesale pricing changes, and labor rate surveys. Major wholesale price changes trigger immediate updates.
Prices cover panels, Enphase IQ8+ microinverters, IronRidge racking, full electrical work, permitting, engineering, utility interconnection, monitoring setup, and NuWatt's 25-year workmanship warranty. Battery storage is priced separately.
The residential solar investment tax credit (Section 25D) expired December 31, 2025 under the One Big Beautiful Bill Act (OBBBA) signed July 4, 2025. Homeowners who purchase solar with cash or a loan receive $0 in federal tax credits.
All prices on this page reflect the post-ITC reality. However, third-party-owned systems (like NuWatt’s Propel $0 Down Solar) can still claim 30% under Section 48/48E because the financing company — not the homeowner — owns the system and captures the credit.
Learn how solar still works without the ITCNuWatt uses a piecewise-linear pricing model anchored at 4 system sizes (5, 8, 15, 25 kW) for each state. The base price uses Silfab 440W panels, with Hyundai at -$0.07/W and REC at +$0.19/W. A $5,000 minimum gross profit floor ensures sustainable installer economics. Prices are reviewed and updated monthly based on equipment costs, labor rates, and permit fees.
State-by-state pricing differences reflect local labor costs, permit and interconnection fees, sales tax treatment, roof accessibility norms, and competitive market dynamics. Massachusetts and New Hampshire tend to be higher due to permitting complexity and prevailing wages. Texas and Pennsylvania are lower due to simpler permitting, lower labor costs, and larger average system sizes that benefit from volume pricing.
The residential solar tax credit (Section 25D) expired on December 31, 2025 under the OBBBA signed July 4, 2025. Homeowners who purchase solar with cash or a loan receive $0 in federal tax credits. However, third-party-owned systems (leases, PPAs) can still claim 30% under Section 48/48E, which is why Propel financing passes savings to homeowners through lower monthly payments.
The NuWatt Solar Price Index is updated monthly. Pricing anchors are reviewed against actual project costs, equipment wholesale pricing, and regional labor rate changes. Historical data is preserved to show trends over time.
These are fully installed, turnkey prices including equipment (panels, inverters, racking), labor, permitting, engineering, interconnection, and a 25-year workmanship warranty. The only exclusion is battery storage, which is priced separately.
Installers across the industry reduced margins and renegotiated equipment pricing to keep solar economically viable without the 30% federal credit. NuWatt specifically restructured its pricing tiers and introduced the Hyundai entry tier at $0.07/W below the Silfab standard to provide a more affordable option for price-sensitive homeowners.
