Why the Sticker Is Not the Real Price
Most solar shopping happens in the wrong order. Homeowners get a quote, look at the total, and either flinch or sign. The sticker on the quote is rarely the price you actually pay, and the gap between sticker and post-incentive cost is the whole conversation worth having.
The 30% Residential Clean Energy Credit (the official IRS name for what most people still call the federal solar tax credit) applies through 2032 to the full cost of a qualifying residential solar PV system, including equipment, installation, labor, permits, and inspections. State, county, and utility programs add additional rebates, performance payments, or tax abatements on top in many markets. Net metering rules turn excess generation into bill offsets that compound over the life of the system.
None of that complexity changes the underlying permit-declared cost. It just changes what you eventually pay. So the right way to read a solar quote is to compare its bottom line to permit data first, confirm the install scope is honest, and then layer the incentives on as a second-order calculation.
The Permit Data From 13 Marquee Metros
The table below pulls solar permit medians from 13 metros where city-scoped data is available. As with HVAC, the spread between markets is wide. Texas and Carolina markets cluster lower; California and the Northeast cluster higher; the underlying drivers are different but the city-by-city read is the only honest one.
| Metro | Median | Middle 50% | Permits |
|---|---|---|---|
| Portland, OR | $6,750 | $500 to $6,750 | 364 |
| Minneapolis, MN | $7,586 | $5,200 to $11,606 | 1,428 |
| Austin, TX | $8,000 | $1,800 to $19,000 | 181 |
| Charlotte, NC | $8,600 | $2,352 to $16,500 | 5,044 |
| Los Angeles, CA | $12,000 | $1,500 to $31,349 | 75 |
| Houston, TX | $15,358 | $8,276 to $24,000 | 934 |
| Boston, MA | $16,717 | $9,000 to $27,904 | 7,252 |
| Dallas-Fort Worth, TX | $16,800 | $9,971 to $25,000 | 753 |
| Chicago, IL | $17,917 | $11,080 to $24,928 | 2,737 |
| San Francisco, CA | $26,184 | $15,000 to $42,427 | 106 |
| New York, NY | $30,000 | $22,800 to $40,800 | 825 |
| San Diego, CA | $31,398 | $20,000 to $52,000 | 78 |
These numbers are declared values at permit-pull time, not retail sticker prices. Final invoices typically run 5 to 20 percent higher because of system size adjustments and post-permit changes. The medians are conservative on purpose; the underlying permit count is shown so you can read the confidence yourself.
The 30 Percent Federal Credit Explained Quickly
The Residential Clean Energy Credit (Section 25D of the Internal Revenue Code) is a non-refundable federal tax credit equal to 30% of the cost of a qualifying residential solar PV system installed between 2022 and 2032. Non-refundable means it offsets income tax liability, not refunds you cash beyond what you owe. If your federal tax liability is smaller than the credit, the unused portion carries forward to future tax years.
- Eligible costs include solar PV panels, inverters, batteries with capacity of 3 kWh or greater, mounting equipment, balance-of-system components, labor for installation, permit and inspection fees, and electrical wiring directly related to the system.
- The system must be installed at a residence in the United States that you use as a home. Both primary and secondary residences qualify; rental properties do not.
- You must own the system. Leased systems and PPA agreements do not qualify for the credit because you do not own the equipment; the lessor or PPA provider does and may already be claiming a separate commercial credit.
- The credit phases down to 26% for installs in 2033 and 22% for installs in 2034, then expires for residential installs after 2034 unless extended.
Where State and Utility Incentives Stack
The federal credit is the floor. State and utility programs are the headroom, and they vary so much by zip code that a national summary would mislead more than it informs. The DSIRE database (Database of State Incentives for Renewables and Efficiency) is the canonical reference. HomeQuotr ingests DSIRE data on day zero for solar and surfaces incentive programs on each /solar/[city] page so you can see what stacks where you live.
- Performance-based incentives (PBIs) pay you per kWh generated over a fixed term, on top of net metering. Massachusetts SMART, New York NY-Sun, and Illinois Adjustable Block Program are examples.
- Up-front rebates reduce the install cost directly before the federal credit calculates. Some California utilities (SGIP for batteries), Texas Oncor, and several municipal utilities run rebates of $500 to $5,000 depending on system size and program tier.
- State tax credits or property tax exemptions further reduce the effective cost. South Carolina, New York, and Hawaii are notable examples; check DSIRE for your state.
- Net metering rules determine whether your excess generation gets credited at retail rate, wholesale rate, or somewhere in between. The difference can be thousands of dollars over the life of the system.
How to Read a Solar Quote Without Getting Played
Solar sales is a high-pressure category. Door-knocking sales reps, lead-broker quotes, and platform-routed estimates have driven the average solar quote in the U.S. higher than what permit data shows installs actually cost.
- Get the system size in watts (DC) on the page. Not in dollars per month, not in payment terms, not in marketing language. A 7.5 kW system installed for $25,000 is $3.33 per watt; a comparable system in your city should land near the local price-per-watt norm.
- Compare the bottom line to your city's permit median. If the quote is at or above the 75th percentile, ask why. If it is meaningfully above the 95th percentile, walk away and pull a second quote.
- Confirm the system is owned, not leased or PPA. Owned systems qualify for the federal credit; leased systems do not.
- Pull apart the financing terms. A solar loan with a high APR can quietly add 30 to 50 percent to the lifetime cost; a HELOC or 0% promotional rate is usually cheaper.
- Ask whether the contractor pulls the permit. They should. Homeowner-pulled solar permits push code liability onto you in a way that almost never benefits the homeowner.
How to Size a System Honestly
System size is the line item that drives every other line item. Get the size wrong and the rest of the math is wrong too. The honest sizing process starts with your last 12 months of electric bills and your roof.
Start with annual kWh consumption from your utility bills. A typical U.S. home consumes 8,000 to 14,000 kWh per year. Multiply your annual consumption by an offset goal (most homeowners target 90 to 100 percent offset, but the right answer depends on your tariff and net metering rules) and you have an annual generation target. Divide by your zip code's solar production factor (the kWh per kW per year for your specific climate, available from NREL's PVWatts tool) and you have the system size in kW DC that meets your generation target.
Now check the roof. Available unshaded south-facing roof area divided by roughly 60 square feet per kW gives you the maximum installable size. If your roof can hold a system larger than your generation target, take the smaller number; do not let an installer talk you into oversizing because "more solar is always better." An oversized system on a net-metered tariff that credits exports below retail rate is a bad investment dressed up as an aspirational one.
- 8,000 to 14,000 kWh per year is typical residential consumption. Pull your last 12 utility bills before any conversation with an installer.
- NREL's PVWatts tool gives you a free zip-code-specific production estimate. Use it to sanity-check installer claims about how many kWh a system will generate per year.
- Roof orientation, tilt, and shading materially change the math. South-facing is best in the U.S.; east and west work; north should not have panels on it.
- Shading from trees, dormers, or adjacent buildings during peak production hours can cut a panel's output 30 to 70 percent. Module-level optimizers and microinverters mitigate but do not eliminate this.
- If your installer is sizing significantly above your generation target, ask why. Common honest reasons: planned EV adoption, planned electrification of heating, anticipated household growth. Common dishonest reason: bigger system means bigger sales commission.
Batteries and the 2026 Economics
Battery storage is increasingly bundled into residential solar and the federal credit covers it (3 kWh or greater capacity, owned not leased). The economics changed in 2025 with new utility rate structures (time-of-use peaks getting steeper in California, time-of-day net metering replacing one-to-one in several states) and continue to shift in 2026.
The short read: if your utility imposes time-of-use rates with significant peak premiums, batteries pay back faster. If your utility still offers full one-to-one net metering, batteries are a resilience purchase more than a financial purchase. Either way, the federal credit applies to the install cost when bundled with solar, which materially changes the math.
HomeQuotr does not publish standalone battery pricing because most jurisdictions bundle battery permits inside the parent solar permit, making clean isolation difficult (and yes, this is the same reason battery and storage permits did not make the launch trade list). For battery questions, the closest signal is the spread between battery-bundled and battery-excluded solar quotes in your specific market.
