How much do solar panels cost?
Solar panel costs vary based on system size, equipment quality, and your location. Here’s what typical systems cost in 2026:
| System Size | Before Tax Credit | After 30% Credit | Best For |
|---|---|---|---|
| 4 kW (small) | $10,000–$14,000 | $7,000–$9,800 | Small homes, low usage |
| 6 kW (medium) | $15,000–$21,000 | $10,500–$14,700 | Average homes |
| 8 kW (larger) | $20,000–$28,000 | $14,000–$19,600 | Larger homes |
| 10 kW (large) | $25,000–$35,000 | $17,500–$24,500 | High usage, EVs |
| + Battery storage | +$10,000–$20,000 | +$7,000–$14,000 | Backup power |
What determines your solar cost?
- System size: Based on your electricity usage and roof space
- Equipment: Premium panels (SunPower, LG) cost more than budget options
- Inverter type: String inverters cheaper; microinverters more efficient
- Roof complexity: Multiple angles, obstructions add cost
- Location: Permit costs and labor rates vary by region
- Battery: Adding storage significantly increases cost
The net cost is what matters
A $25,000 system becomes $17,500 after the 30% federal tax credit. If you also get $2,000 in state incentives and save $1,800/year on electricity, your effective payback period drops to 8–9 years — with 20+ years of free electricity after that.

Solar loans: The most popular option
Solar loans are specifically designed for solar installations. They typically offer lower rates than personal loans and may have features like deferred payments until you receive your tax credit.
How solar loans work
- Choose a solar installer who partners with solar lending companies
- Apply through the installer or directly with lenders like Mosaic, Sunlight, or GoodLeap
- Get approved based on credit, income, and home value
- System is installed; you own it from day one
- Make monthly payments over 10–25 years
- Claim the 30% tax credit yourself
Solar loan rates and terms (2026)
- APR range: 4%–9% (varies by credit and term)
- Loan amounts: $5,000–$100,000+
- Terms: 10–25 years
- Down payment: Usually $0
- Secured vs. unsecured: Both available; secured has lower rates
Deferred payment loans
Some solar loans let you defer payments for 12–18 months so you can apply your tax credit refund to the loan principal — effectively reducing your financed amount by 30%.
$0-down solar loans
Most solar loans require no down payment. Your monthly loan payment is designed to be lower than your current electricity bill, so you “save” from day one.
Re-amortization option
After applying your tax credit to the principal, some lenders re-amortize the loan — lowering your monthly payment for the remaining term.
Solar loan pros
- You own the system (build equity)
- You keep the 30% tax credit
- Lower rates than personal loans
- Long terms = lower monthly payments
- $0 down options available
Solar loan cons
- Must meet credit requirements
- Some are secured by your home
- Long terms = more interest paid
- Dealer fees may be built into price
Watch for dealer fees
Some solar installers inflate system prices to cover financing fees (3%–8% of loan). A $25,000 system might become $27,000 if financed. Ask for both cash and financed prices, and compare the true cost.
Personal loans for solar panels
Personal loans offer an alternative to solar-specific financing. They give you flexibility to choose any installer and may have simpler terms — though usually at higher rates.
When personal loans make sense
- You found a great installer who doesn’t offer financing
- You want to avoid secured loans (that use your home)
- You prefer shorter terms (2–7 years vs. 10–25)
- Your credit qualifies for competitive rates (under 10%)
- You want to compare lenders independently
Personal loan vs. solar loan comparison
| Factor | Solar Loan | Personal Loan |
|---|---|---|
| Typical APR | 4%–9% | 7%–24% |
| Terms | 10–25 years | 2–7 years |
| Secured option | Yes (lower rate) | Usually unsecured |
| Deferred payment | Often available | No |
| Dealer fees | May be built in | No |
| Choice of installer | May be limited | Any installer |
Best for
Homeowners who want total independence from installer financing, have excellent credit (for competitive rates), or prefer to pay off the system faster with a shorter-term loan.
Solar leases and PPAs: $0 down, no ownership
With a solar lease or Power Purchase Agreement (PPA), a solar company installs panels on your roof at no upfront cost. You don’t own the system — you pay the company instead of the utility.
Solar lease
- Fixed monthly payment (e.g., $100/month)
- Solar company owns, maintains, and insures the system
- Lease terms typically 20–25 years
- Annual escalator (1–3% payment increase per year)
PPA (Power Purchase Agreement)
- Pay per kilowatt-hour (e.g., $0.12/kWh)
- Solar company owns, maintains, and insures the system
- Terms typically 20–25 years
- Rate usually lower than utility but may escalate
Lease/PPA pros
- $0 upfront cost
- No maintenance responsibility
- Immediate savings on electricity
- No credit requirements (usually)
Lease/PPA cons
- You don’t own the system
- Solar company keeps tax credit
- Less total savings over 25 years
- Can complicate home sales
- Escalators increase payments
The ownership trade-off
Over 25 years, owning your system (with a loan) typically saves $15,000–$30,000 more than leasing. You keep the 30% tax credit and any net metering credits. Leases make sense only if you can’t qualify for financing or don’t want any financial commitment.
Lease/PPA and home sales
If you sell your home with a leased system, the buyer must either assume the lease or you must buy out the remaining term. This can complicate sales. With owned systems (financed or paid off), solar typically adds value to your home.
Federal tax credit and incentives
The 30% federal solar tax credit (ITC) is the biggest financial incentive for going solar. Understanding how it works helps you plan your financing strategy.
Federal Investment Tax Credit (ITC)
- 2024–2032: 30% of system cost
- 2033: 26%
- 2034: 22%
- 2035+: 0% (unless extended)
How the tax credit works
The ITC is a dollar-for-dollar reduction in your federal taxes. A $25,000 system = $7,500 credit. If you owe $10,000 in taxes, you’ll owe $2,500 instead.
What qualifies
Solar panels, inverters, mounting equipment, installation labor, battery storage, and sales tax (in some states) all qualify for the 30% credit.
Ownership required
You must OWN the system (cash, solar loan, personal loan, HELOC). Leases and PPAs don’t qualify — the solar company claims the credit.
State and local incentives
- State tax credits: Some states offer additional credits (5–25%)
- Rebates: Utility or state rebates ($500–$3,000)
- Net metering: Sell excess electricity back to the grid
- SRECs: Solar Renewable Energy Credits (in some states)
- Property tax exemption: Many states exempt solar from property tax increases
Stack your incentives
A $28,000 system could have: $8,400 federal credit + $2,000 state rebate + $1,500 utility rebate = $11,900 in incentives. Your effective cost: $16,100. Search DSIRE (Database of State Incentives for Renewables & Efficiency) for your state’s programs.
Which solar financing option is best for you?
Use this decision framework:
Have cash available?
Cash purchase offers maximum savings — no interest, full tax credit, fastest payback. If you have the funds and won’t deplete emergency reserves, cash is best.
Want to own with $0 down?
Solar loan is the most popular choice. You own the system, keep the tax credit, and pay less than your current electricity bill.
Want flexibility in installers?
Personal loan or HELOC lets you use any installer. Good if you found a great deal outside of solar financing networks.
Can’t qualify for loans?
Lease or PPA has minimal credit requirements. You won’t own the system, but you’ll still save on electricity with $0 upfront.
Want lowest possible rate?
HELOC typically offers the lowest rates (8–10%) if you have home equity. Interest may also be tax-deductible.
Planning to move in 5–10 years?
Ownership (loan) still wins — solar adds home value. Leases complicate sales. Even with a short stay, you’ll recover most of the investment.

Comparison Summary
Frequently asked questions
What credit score do I need for solar financing?
Most solar loans require 650–700+ for the best rates. Some lenders accept 600+. Personal loans typically require 580–670. Leases and PPAs often have minimal or no credit requirements.
Is it better to lease or buy solar panels?
Buying (with cash or loan) is better for most homeowners. You own the system, keep the 30% tax credit, and save $15,000–$30,000 more over 25 years. Leasing makes sense only if you can’t qualify for financing.
How do I claim the solar tax credit?
File IRS Form 5695 with your tax return. You’ll need documentation of your system cost. The credit reduces your tax liability dollar-for-dollar. If your credit exceeds your tax bill, you can carry it forward to future years.
What happens to solar panels if I sell my house?
If you own the panels, they typically add 4%+ to home value. If leased, the buyer must assume the lease or you buy it out. Owned systems are much easier to handle in sales and more attractive to buyers.
Can I get solar with no money down?
Yes. Most solar loans offer $0 down. Leases and PPAs also require no upfront payment. Your monthly payment is typically designed to be less than your current electricity bill, so you “save” from day one.
How long do solar panels last?
Most solar panels are warrantied for 25 years and can last 30–40 years. Degradation is about 0.5% per year, so after 25 years they’ll still produce ~87% of original capacity. This outlasts most loan terms.
