Solar panels are a financial investment, and like any investment, you want to know: How much will I save? How long until it pays for itself? And what is my return?
The short answers: most homeowners save $1,500+ per year, reach payback in 6–10 years, and earn a 10–15% annual return on investment – outperforming the stock market with significantly less risk. But the exact numbers depend on your specific situation.
This guide breaks down exactly how solar savings work, what determines your payback period, and how to calculate your long-term return.

How Much Do Solar Panels Save Per Year?
Your annual solar savings equal the amount of electricity your system produces multiplied by the rate you would have paid your utility for that electricity.
Here is what typical annual savings look like in Gold Path Solar’s service areas:
| Location | Average Utility Rate | Typical System Size | Annual Production | Estimated Year 1 Savings |
|---|---|---|---|---|
| Columbus, OH | $0.14 – $0.20/kWh | 9 – 11 kW | 10,000 – 13,000 kWh | $1,400 – $2,600 |
| Dayton, OH | $0.14 – $0.19/kWh | 8 – 10 kW | 9,000 – 12,000 kWh | $1,260 – $2,280 |
| Cincinnati, OH | $0.15 – $0.22/kWh | 9 – 11 kW | 10,000 – 13,500 kWh | $1,500 – $2,970 |
| Lexington, KY | $0.12 – $0.17/kWh | 8 – 10 kW | 9,500 – 12,500 kWh | $1,140 – $2,125 |
| Louisville, KY | $0.12 – $0.18/kWh | 8 – 10 kW | 9,500 – 12,500 kWh | $1,140 – $2,250 |
| Greenville, SC | $0.13 – $0.19/kWh | 8 – 10 kW | 10,500 – 14,000 kWh | $1,365 – $2,660 |
These are Year 1 savings. The critical point most people miss is that your savings grow every year because utility rates increase while your solar production cost stays at zero.
How Do Solar Savings Grow Over Time?
Utility electricity rates in the United States have increased an average of 3–5% per year over the past decade. In some markets, the increases have been even higher. This rate escalation is the single most powerful driver of solar ROI.
Here is how annual savings compound for a homeowner currently saving $1,800/year with a 4% annual rate increase:
| Year | Annual Savings (without solar) | Cumulative Savings |
|---|---|---|
| Year 1 | $1,800 | $1,800 |
| Year 5 | $2,100 | $9,750 |
| Year 10 | $2,560 | $21,600 |
| Year 15 | $3,115 | $36,100 |
| Year 20 | $3,790 | $53,600 |
| Year 25 | $4,610 | $74,900 |
That is nearly $75,000 in cumulative savings over the life of a system that cost $17,500 after the tax credit. This is why solar is one of the best financial decisions a homeowner can make – the return is not speculative, it is based on the unavoidable reality that electricity prices go up.

What Is the Payback Period for Solar Panels?
How Long Does It Take for Solar Panels to Pay for Themselves?
The payback period is the number of years it takes for your cumulative electricity savings to equal your net cost of going solar. After the payback point, everything your system produces is essentially free electricity.
Typical payback periods in Gold Path Solar’s service areas:
| Location | Estimated Payback Period |
|---|---|
| Ohio (Columbus, Dayton, Cincinnati) | 7 – 10 years |
| Kentucky (Lexington, Louisville) | 8 – 11 years |
| South Carolina (Greenville) | 5 – 8 years |
South Carolina has the shortest payback period because of the state’s additional 25% state tax credit on top of the 30% federal credit, combined with strong sun exposure. For full details on available incentives, see our solar financing, tax credits, and incentives guide.
What Factors Affect Solar Payback Period?
Your payback period is determined by:
- Net system cost – lower cost (via incentives or competitive pricing) means faster payback
- Local electricity rate – higher rates mean each kWh your panels produce is worth more
- Rate escalation – faster rate increases accelerate your payback
- System production – more sun hours and better panel efficiency mean more kWh produced
- Net metering policy – full retail credit maximizes the value of excess production
- Financing terms – interest rates and loan length affect your total cost of ownership
The factor you have the most control over is choosing the right installer. An installer that overcharges, uses cheap equipment, or designs an underperforming system directly extends your payback period. Gold Path Solar’s competitive pricing (driven by our referral-based growth model rather than expensive advertising) and Tier-1 equipment help our customers achieve the shortest possible payback.

What Is the Return on Investment for Solar Panels?
How Do You Calculate Solar Panel ROI?
Solar ROI can be calculated as:
ROI = (Lifetime Savings − Net System Cost) ÷ Net System Cost × 100
For a typical example:
- Net system cost (after 30% ITC): $17,500
- 25-year cumulative savings (with 4% rate escalation): $74,900
- ROI: ($74,900 − $17,500) ÷ $17,500 × 100 = 328% total return
- Annualized ROI: approximately 10–15% per year
For comparison, the S&P 500 has historically returned an average of 7–10% annually – and with significantly more volatility and risk. Solar delivers a comparable or better return with predictable, low-risk cash flows. For a deeper comparison, see our article on solar panels vs. the stock market.
Does Solar ROI Include the Home Value Increase?
The ROI calculation above only accounts for electricity savings. It does not include the home value increase from solar, which studies show averages 4–7% of the home’s value. If you sell your home during the system’s lifetime, the increased sale price represents additional return on your investment.
Learn more in our solar panels and home value guide.
How Does Financing Affect Solar ROI?
Cash Purchase ROI
Paying cash delivers the highest ROI because you avoid interest payments. Your return is purely savings minus system cost. Cash buyers typically see 12–20% annual returns depending on their electricity rate and system production.
Solar Loan ROI
With a solar loan, your ROI is reduced by the interest paid over the loan term. However, most loan customers are cash-flow positive from day one – meaning your monthly solar payment is less than your old electric bill, so you save money every month even before the loan is paid off. Once the loan is paid off, your electricity is essentially free for the remaining life of the system.
Gold Path Solar’s zero-closing-cost financing improves loan ROI compared to lenders that roll dealer fees into your balance. Every dollar of interest you pay should be on your actual system cost, not hidden bank charges. Learn more about solar financing options.
What Is the ROI of Doing Nothing?
This is the question most people forget to ask. If you do not go solar, your “return” is a guaranteed loss – you will pay your utility company $50,000 to $90,000+ over 25 years with zero equity, zero return, and zero protection against rate increases. The cost of inaction is the most expensive option.

Theory is useful, but real-world results are what matter. Gold Path Solar publishes verified case studies from actual customers showing system sizes, production data, and savings. Visit our Solar Spotlights page to see what homeowners in your area are actually saving.
These are not cherry-picked best-case scenarios – they represent typical results from properly designed and installed systems. Our track record of delivering on projected savings is why so many of our new customers come from referrals from satisfied homeowners.
What Can Reduce Your Solar Savings?
It is important to understand the factors that can negatively impact your return:
Does Panel Degradation Reduce Savings Over Time?
Yes, but minimally. Solar panels degrade at approximately 0.3–0.5% per year, meaning after 25 years they still produce 85–90% of their original output. This degradation is factored into any reputable installer’s production projections. Higher-quality Tier-1 panels degrade more slowly than budget panels. For more details, see our solar panel maintenance, lifespan, and warranty guide.
Can a Poorly Designed System Hurt Your ROI?
Absolutely. This is the biggest risk to your solar investment. A system that is undersized, improperly oriented, affected by unaccounted shading, or built with cheap equipment will underperform projections and extend your payback period. This is why choosing the right installer matters more than finding the lowest price.
Gold Path Solar’s design process uses your actual electricity data, detailed site surveys by in-house technicians, and industry-leading design software to ensure your system performs as promised. Our employee-owned team has a direct stake in your satisfaction because our business grows through your referrals.
Can Net Metering Policy Changes Affect Savings?
If your state or utility reduces net metering credits after you go solar, it could affect your return. However, most states grandfather existing solar customers into the policy that was active when they interconnected. This is one of the strongest arguments for going solar sooner rather than later – locking in current favorable net metering terms. Read more about why net metering matters.
Solar Savings Calculator: Estimate Your Numbers
While an online estimate cannot replace a professional analysis, here is how to rough out your own numbers:
- Find your annual electricity cost. Add up 12 months of electric bills. Example: $1,800/year.
- Estimate your system offset. Most systems are designed to offset 80–100% of usage. At 90%: $1,800 × 0.90 = $1,620 in Year 1 savings.
- Get your net system cost. Ask for a quote or use averages from our solar panel cost guide. Subtract the 30% federal tax credit and any state credits. Example: $25,000 − $7,500 = $17,500.
- Calculate simple payback. $17,500 ÷ $1,620 = approximately 10.8 years. With 4% annual rate increases factored in, the actual payback is closer to 8–9 years.
- Project 25-year savings. With compounding rate increases, expect 3–4× your Year 1 savings as total cumulative savings. $1,620 × ~46 (cumulative factor with 4% escalation) = ~$74,500.

Frequently Asked Questions About Solar ROI and Savings
How much do solar panels save per month?
Most Gold Path Solar customers save $100–$250+ per month on electricity, depending on system size, electricity rate, and usage. Your specific savings are calculated during the free consultation based on your actual bills.
How much do solar panels save over 25 years?
Typical lifetime savings range from $35,000 to $75,000+, depending on your system size, local electricity rates, and rate escalation. Homeowners with higher electricity usage and rates in areas with strong sun exposure see the highest cumulative savings.
Is solar a good investment in 2026?
Yes. The 30% federal tax credit is still available, equipment costs have stabilized at competitive levels, and utility rates continue to rise. Every year you wait, you lose another year of savings while your utility costs increase. The financial case for solar has never been stronger.
Do solar panels pay for themselves?
For the vast majority of qualifying homeowners, yes. With a typical payback period of 6–10 years and a system lifespan of 25–30+ years, solar panels pay for themselves and then continue generating free electricity for 15–20+ years beyond the break-even point.
What is the average ROI on solar panels?
Annual ROI typically ranges from 10–15% for cash purchases and 8–12% for financed systems, depending on local conditions. This compares favorably to the stock market’s historical average of 7–10% – with significantly less risk and volatility.
Will solar panels save me money if my electric bill is already low?
If your monthly bill is below $75, the financial case for solar is weaker and the payback period longer. However, if you anticipate increasing your electricity usage (EV, heat pump, home addition), locking in solar now at today’s equipment prices and the 30% tax credit can still be a smart long-term play.
