Residential solar lost its biggest sales line on December 31, 2025, when the 30% Section 25D tax credit for homeowner owned systems expired. US homes added 995 MWdc of solar in Q2 2026, down 12% from a year earlier, and SEIA and Wood Mackenzie now expect the residential segment to shrink 23% in 2026, per the Q3 2026 Solar Market report.
Fewer buyers means every installer chases the same homeowners. Wood Mackenzie projects customer acquisition cost will jump about 40%, from $0.60 per watt in 2025 to $0.84 per watt in 2026, and Google and Meta solar click prices rose 15% to 30% in June 2026 alone. Freedom Forever, the second largest residential installer of 2025 with a 6.1% market share, filed for Chapter 11 in April 2026.

SunPower, Titan Solar, Lumio, Sunnova and Mosaic all failed between 2024 and 2025.
Solar Pricing and Financing Statistics

- The median quoted solar price was $2.57 per watt before incentives, up about 3% from late 2025.
- Installers quoting third party ownership rose from about 14% at the start of 2026 to about 41% by mid year.
- A prepaid PPA costs 57% less per kWh than a cash purchase, and a prepaid lease costs 39% less.
- 76% of homeowners show interest in battery storage, yet only 31% add a battery to the order. Batteries average $1,130 per kWh.
- 74% of contractors report higher labor rates, and 58% plan to grow through added services such as panel upgrades and EV chargers.
Solar Financing Options Compared for Homeowners (H1 2026)
| Comparison | Price Difference per kWh |
|---|---|
| Prepaid PPA vs cash purchase | 57% cheaper |
| Prepaid lease vs cash purchase | 39% cheaper |
| Prepaid PPA vs solar loan | 80% cheaper |

Ad copy and landing pages built around the 30% federal credit on purchased systems are now out of date. Lead with a monthly payment below the utility bill, since that is the offer most buyers receive in 2026.
Solar Customer Acquisition Cost Statistics
- Residential acquisition cost hit a five year low of $0.60 per watt in 2025, about 10% below 2024, as the rush to beat the 25D deadline filled pipelines, per Wood Mackenzie.
- Wood Mackenzie forecasts $0.84 per watt for 2026, a 40% jump, as installers raise marketing budgets and retrain sales teams for leases and PPAs.
- Installer acquisition cost per customer now runs $3,000 to $7,000, up from $2,400 to $5,200 in 2024, according to Lead Gen Economy.

Referrals carry the best economics in solar because every installed customer becomes a reference on the same street. Our roundup of referral marketing statistics covers referral program benchmarks across industries.
Our Analysis: What the 2026 Numbers Mean for Installers
We combined figures from SEIA, Wood Mackenzie, Berkeley Lab, EnergySage and lead market data to calculate figures that sit in separate reports. Each calculation lists its inputs.
Acquisition Cost Now Equals a Quarter of the System Price
Customer Acquisition Cost as a Share of Residential System Price
| Year | Acquisition Cost per Watt | Installed Price per Watt | Acquisition Share of Price | Acquisition Cost per 7.7 kW System |
|---|---|---|---|---|
| 2025 | $0.60 | About $3.41 | 17.6% | About $4,620 |
| 2026 | $0.84 | $3.36 | 25.0% | About $6,470 |
Inputs: Wood Mackenzie acquisition cost, SEIA installed price (2025 price derived from the 1.4% drop) and the Berkeley Lab median system size. Every typical sale now carries about $1,850 more in acquisition cost than in 2025, which lines up with the $3,000 to $7,000 per customer installers report.
The Expired Tax Credit Was Worth About ,940 per Home
A median 7.7 kW system at the EnergySage median of $2.57 per watt costs about $19,790 before incentives. The 30% Section 25D credit cut that by about $5,940. Cash and loan buyers now pay that amount themselves, which explains why lease and PPA quotes jumped from 14% to 41% of installer quotes in the first half of 2026: third party owners still claim a commercial tax credit on qualifying projects and pass part of it through the monthly payment.
The Industry Spends About 5 Million a Quarter to Win Homeowners
The 995 MWdc installed in Q2 2026 equals about 129,000 homes at the 7.7 kW median. At $6,470 in acquisition cost per home, residential installers spent roughly $835 million in one quarter on sales and marketing, about $6,500 for every household that went solar.
Closing the Battery Gap Adds ,000 per Order
A median 13.5 kWh battery at $1,130 per kWh sells for about $15,250. With 76% of homeowners interested and 31% buying, each 10 point gain in battery attach rate adds about $152,500 in revenue per 100 solar sales, with zero extra lead spend. Battery offers belong in the first ad and landing page, before the sales visit.
Price Spread Makes Comparison Shopping Inevitable
Across the top 100 installers, median prices ran from $2.40 to $6.30 per watt in 2025. On a 7.7 kW home that is $18,480 at the low end and $48,510 at the high end, a gap of about $30,000 for the same size system. Homeowners who collect three quotes see that spread, so marketing that publishes price per watt and financing terms up front wins trust before the first call.
What One Installed Solar System Costs in Leads
Lead prices hide the real cost of a sale. We converted the 2026 lead prices above into media cost per installed system using the post 25D funnel: a 25% lead to appointment rate, a 25% appointment to sale rate and an 87% sale to install rate.
Estimated Media Cost per Installed Residential Solar System (2026)
| Channel | Midpoint Cost per Lead | Media Cost per Installed System |
|---|---|---|
| Google Search lead | $275 | About $5,060 |
| Inbound phone call | $200 | About $3,680 |
| Exclusive real time web lead | $80 | About $1,470 |
| Google Local Services Ads | $70 | About $1,290 |
| Door knock appointment | $55 | About $210 plus rep commission |
Each web lead needs about 18 leads per installed system at these rates, so a $275 search lead turns into roughly $5,060 of media per install. Door knocking skips the appointment step, which explains its low media cost, though rep commissions of several thousand dollars per deal sit on top. Every point gained on appointment setting lowers these figures more than any bid change in Google Ads.
Speed changes the math most. Raising the set rate on a $275 search lead from 25% to 55% by calling within 5 minutes cuts media cost per install from about $5,060 to about $2,300 with the same ad budget.
