The cost of solar panels has dropped dramatically over the past decade, but it is still a significant investment. The good news is that a combination of federal tax credits, state incentives, and flexible financing options makes solar affordable for most homeowners – often with zero money down and monthly payments lower than your current electric bill.
This guide explains every financial tool available to help you pay for solar, maximize your savings, and make the smartest investment decision for your situation.

The Federal Solar Investment Tax Credit (ITC)
What Is the Federal Solar Tax Credit?
The federal Investment Tax Credit (ITC) is the single most valuable solar incentive available to homeowners. It allows you to deduct 30% of your total solar installation cost directly from your federal income taxes.
This is a tax credit, not a deduction. That means it reduces your tax bill dollar for dollar. If you owe $8,000 in federal taxes and your solar tax credit is $7,500, you pay only $500 in federal taxes that year.
What Does the Solar Tax Credit Cover?
The 30% credit applies to the total cost of your solar installation, including:
- Solar panels
- Inverters (string inverters or microinverters)
- Racking and mounting hardware
- Wiring and electrical components
- Installation labor
- Permitting and inspection fees
- Battery storage systems (if installed with or after solar)
- Sales tax paid on the system
For a $25,000 solar system, the ITC saves you $7,500. If you also add a $10,000 battery system, the total credit on your $35,000 project is $10,500.
How Long Is the 30% Solar Tax Credit Available?
The current ITC schedule under the Inflation Reduction Act is:
| Year of Installation | Tax Credit Percentage |
|---|---|
| 2022 – 2032 | 30% |
| 2033 | 26% |
| 2034 | 22% |
| 2035 and beyond | 0% (unless extended by Congress) |
The credit is based on the year your system is placed in service (activated), not the year you sign a contract. Planning ahead matters – if you start the process in late 2032, permitting delays could push your activation into 2033 when the credit drops to 26%.
What If I Do Not Owe Enough in Taxes to Use the Full Credit?
If your tax credit is larger than your federal tax liability in the year of installation, you can carry the remaining credit forward to future tax years. There is no limit on how many years you can carry it forward (under current rules), so you will eventually use the full credit.
For example, if your credit is $7,500 but you only owe $5,000 in federal taxes this year, you would pay $0 in federal taxes this year and have $2,500 in credit to apply next year.
Important: The solar tax credit is non-refundable, meaning it can reduce your tax liability to zero but cannot generate a tax refund. Consult a tax professional to understand how the credit applies to your specific tax situation.

State and Local Solar Incentives
What Solar Incentives Are Available in Ohio?
Ohio’s solar incentive landscape includes:
- Net metering: Ohio requires investor-owned utilities (AEP Ohio, Duke Energy Ohio) to offer net metering, allowing you to receive credits for excess solar energy sent to the grid. Credits are typically valued at the retail electricity rate.
- Property tax exemption: The added value of a solar energy system is exempt from Ohio property taxes for the life of the system. Your home value goes up, but your property taxes do not increase because of solar.
- Federal tax credit: The 30% ITC is available to all Ohio homeowners.
Ohio does not currently offer a state-level solar tax credit or rebate, which makes the federal ITC and net metering especially important for Ohio homeowners. Columbus, Dayton, and Cincinnati homeowners should take full advantage of these while they are available.
What Solar Incentives Are Available in Kentucky?
Kentucky offers several meaningful solar incentives:
- Net metering: Kentucky law requires utilities to offer net metering for systems up to 45 kW. Excess energy credits are valued at the retail rate and roll over month to month.
- Sales tax exemption: Solar energy equipment is exempt from Kentucky sales tax, saving you 6% on the equipment portion of your installation cost.
- TVA programs: Some areas served by the Tennessee Valley Authority may have access to additional programs or green energy credits.
- Federal tax credit: The 30% ITC applies to all Kentucky installations.
Between the federal credit and sales tax exemption, Kentucky homeowners in Lexington and Louisville can reduce their solar cost significantly.
What Solar Incentives Are Available in South Carolina?
South Carolina is one of the best states in the country for solar incentives:
- South Carolina state solar tax credit: Homeowners can claim a state tax credit of up to 25% of the cost of their solar system, capped at $3,500 per year but carrying forward for up to 10 years. This stacks on top of the 30% federal credit.
- Net metering: South Carolina requires utilities to offer net metering with full retail rate credits for excess solar production.
- Property tax exemption: Solar energy systems are exempt from South Carolina property taxes.
- Federal tax credit: The 30% ITC applies to all South Carolina installations.
When you combine the 30% federal credit with South Carolina’s 25% state credit, Greenville area homeowners can reduce their solar cost by more than half. This makes South Carolina one of the fastest payback markets in Gold Path Solar’s service area.

How to Pay for Solar Panels: Financing Options Explained
There are three primary ways to pay for a residential solar system: cash purchase, solar loan, or lease/PPA. Each has different financial implications.
Should I Buy Solar Panels with Cash?
Paying cash provides the highest total return on investment because you avoid interest charges. You own the system outright from day one, qualify for the full tax credit, and start saving immediately with no monthly payment.
Best for: Homeowners who have the capital available and want to maximize long-term savings.
Typical ROI: 10–15% annual return on your investment, which outperforms most traditional investments. For a comparison, see our article on solar panels vs. the stock market.
What Is a Solar Loan and How Does It Work?
A solar loan allows you to finance 100% of your system cost with $0 down. You own the system from day one (qualifying for the full tax credit and all incentives), and your monthly loan payment replaces your electric bill – ideally at a lower amount.
This is the most popular option among Gold Path Solar customers. Here is why:
- No upfront cost: You go solar immediately with no cash out of pocket.
- You own the system: Unlike a lease, you build equity and qualify for all tax benefits.
- Immediate savings: If your solar loan payment is lower than your old electric bill, you save money from month one.
- Tax credit accelerates payoff: Many homeowners apply their federal tax credit refund to their loan balance, reducing the principal and lowering future payments.
Typical solar loan terms are 10 to 25 years with interest rates that vary by lender and credit profile. Longer terms mean lower monthly payments but more interest paid over the life of the loan.
What Makes Gold Path Solar’s Financing Different?
Gold Path Solar offers loans with zero closing costs. This is a critical distinction that many homeowners overlook when comparing quotes.
Many solar companies advertise “$0 down” but roll thousands of dollars in dealer fees and closing costs into your loan balance. You end up financing $30,000 for a system that is actually worth $25,000 – paying interest on $5,000 of bank fees that provided zero value to you.
With Gold Path Solar’s zero-closing-cost financing, every dollar you finance goes directly toward your solar system. No dealer fees, no hidden charges, no inflated loan balances.

Should I Lease Solar Panels or Sign a PPA?
Solar leases and Power Purchase Agreements (PPAs) allow you to have solar panels on your roof with little or no upfront cost, but you do not own the system. A third-party company owns the panels and either charges you a monthly lease fee or sells you the electricity at a set rate (PPA).
Gold Path Solar does not recommend leases or PPAs for most homeowners. Here is why:
| Factor | Solar Loan (Own) | Solar Lease / PPA (Rent) |
|---|---|---|
| System ownership | You own it | Third-party company owns it |
| Federal tax credit (30%) | You claim it | Leasing company claims it |
| Home value increase | Yes (4–7%) | Minimal or none |
| Selling your home | Asset that increases sale price | Buyer must assume lease or you buy it out |
| Monthly savings | Higher (no ongoing payments after loan payoff) | Lower (payments continue for full lease term) |
| Long-term cost | Loan ends; free electricity after | Payments may escalate 1–3% annually for 20–25 years |
The only scenario where a lease might make sense is if you cannot qualify for a solar loan and do not have cash to purchase. Even then, the long-term financial outcome is significantly worse than ownership.

How to Maximize Your Solar Savings
How Do You Claim the Federal Solar Tax Credit?
Claiming the ITC is straightforward. When you file your federal income taxes for the year your system is activated, you complete IRS Form 5695 (Residential Energy Credits) and include the credit amount on your Form 1040. Your solar installer should provide documentation of your total system cost.
Gold Path Solar provides all necessary documentation and walks you through the process. We recommend consulting a tax professional to ensure you claim the credit correctly, especially if your tax situation is complex.
Should I Apply My Tax Credit to My Solar Loan?
If you finance your system with a solar loan, applying your federal tax credit refund as a lump-sum payment toward your loan principal is one of the smartest moves you can make. This reduces your loan balance and either lowers your monthly payment or shortens your payoff timeline – effectively giving you the financial benefit of the tax credit faster.
How Does Net Metering Save You Money?
Net metering allows you to send excess solar electricity to the grid during the day and receive credits that offset the electricity you pull from the grid at night. In states with full retail net metering (like Ohio, Kentucky, and South Carolina), each kWh you export is worth the same as each kWh you import. This effectively makes the grid a free battery.
Net metering is what makes it possible to achieve a near-zero electric bill with solar. Without it, you would only benefit from the electricity you consume while the sun is shining. For a deeper explanation, see our guide on what net metering is and how it works.
Solar Financing Comparison: Which Option Saves the Most?
Here is a simplified 25-year financial comparison for a $25,000 solar system in Ohio (before incentives):
| Payment Method | Upfront Cost | 25-Year Total Cost | 25-Year Electricity Savings | 25-Year Net Benefit |
|---|---|---|---|---|
| Cash purchase | $17,500 (after ITC) | $17,500 | ~$50,000+ | ~$32,500+ |
| $0-down solar loan (15-year, 5%) | $0 | ~$24,000 | ~$50,000+ | ~$26,000+ |
| Solar lease (25-year) | $0 | ~$35,000–$45,000 | $0 (savings go to lessor) | ~$5,000–$15,000 |
| No solar (utility only) | $0 | $0 | –$65,000–$90,000 (bills paid) | –$65,000–$90,000 |
The numbers are clear: doing nothing is the most expensive option. Ownership (cash or loan) provides the greatest benefit. Leasing provides some savings but far less than ownership.
Common Questions About Solar Financing and Incentives
Is the solar tax credit a refund?
No. The solar tax credit is non-refundable, meaning it reduces your tax liability but does not generate a refund beyond what you would otherwise receive. If the credit exceeds your tax liability, the excess carries forward to future years.
Do I need good credit for a solar loan?
Most solar lenders require a minimum credit score in the mid-600s, though terms and rates improve with higher scores. Your Gold Path Solar Advocate can discuss available options for your credit profile during your consultation.
Can I pay off my solar loan early?
Most solar loans have no prepayment penalties. Paying off your loan early – especially after applying the federal tax credit – eliminates your monthly payment and maximizes your savings. Confirm prepayment terms with your specific lender.
Will solar financing affect my mortgage or ability to sell my home?
A solar loan is a separate personal loan and does not attach a lien to your home (unlike a HELOC). It shows on your credit report but does not affect your mortgage. When selling, the loan balance can be paid off from sale proceeds, and the increased home value from solar typically more than covers any remaining balance.
Is there a deadline to claim the 30% tax credit?
The 30% credit is available for systems placed in service through December 31, 2032. After that, it drops to 26% in 2033 and 22% in 2034. Congress could extend or modify these dates, but planning based on current law is the prudent approach. Start your solar project now to ensure you receive the full 30% credit.
Can I finance a solar battery along with my panels?
Yes. Battery storage can be included in your solar loan and qualifies for the 30% federal tax credit when installed with a solar system. Adding a battery increases your upfront cost but provides backup power and additional energy management benefits. Learn more in our solar battery guide.
What if my utility changes its net metering policy after I go solar?
Most states grandfather existing solar customers into the net metering policy that was active when they interconnected. This means going solar now locks in the current policy for you, even if rules change for future installations. This is another reason not to wait – current net metering policies in Ohio, Kentucky, and South Carolina are favorable, but they could change. Read more about the case for net metering.
