Solar Panel ROI Calculator: Is Solar Worth It in 2026?
Last updated: February 1, 2026
Calculate your solar panel return on investment. Factor in tax credits, electricity savings, home value increase, and net metering benefits.
Before signing a solar contract, you need to answer one question: "Will this actually save me money?" The calculations aren't complicated, but they depend on your specific electricity rate, local sun hours, and available incentives. Here's how to run the numbers yourself so you can verify any installer's claims.
Solar panel ROI in 2026 is typically 10-20% annually — better than most investment alternatives. The return comes from three sources: electricity bill savings (primary), increased home value (solar adds approximately 4% to home value), and net metering credits for excess production. With the 30% federal tax credit reducing upfront cost, the effective ROI is even higher.
Key Takeaways
- • Average solar ROI: 10-20% annually over system lifetime
- • Solar adds ~4% ($15,000-$25,000) to median US home value
- • 30% federal tax credit significantly boosts ROI
- • Electricity rate increases (2-3%/year historically) improve returns over time
- • Cash purchases deliver the highest ROI; loans provide positive cash flow from day one
- • 25-year total savings typically exceed $30,000-$60,000 depending on location

Use this reference table to estimate your solar needs based on common home sizes:
| Home Size | Est. Usage | System Size | Panels Needed | Est. Cost | After 30% ITC |
|---|---|---|---|---|---|
| 1,000-1,500 sq ft | 7,500 kWh/yr | 5 kW | ~12 | $15,000 | $10,500 |
| 1,500-2,000 sq ft | 10,000 kWh/yr | 7 kW | ~16 | $21,000 | $14,700 |
| 2,000-2,500 sq ft | 12,000 kWh/yr | 8 kW | ~19 | $24,000 | $16,800 |
| 2,500-3,500 sq ft | 15,000 kWh/yr | 10 kW | ~23 | $30,000 | $21,000 |
| 3,500+ sq ft | 20,000 kWh/yr | 13 kW | ~30 | $39,000 | $27,300 |
Frequently Asked Questions
Is solar a good investment in 2026?
For most homeowners, solar delivers 10-20% annual returns — better than the stock market average. With the 30% federal tax credit, declining equipment costs, and rising electricity rates, 2026 is one of the best times to invest in solar. The financial case is strongest in states with high electricity rates and strong net metering policies.
How much does solar increase home value?
Studies show solar panels increase home value by approximately 4%, or about $20 for every $1 of annual electricity savings. For a system saving $1,500/year, that translates to roughly $30,000 in added home value. Owned systems (not leased) provide the full value boost.
What if I move before the payback period?
Solar panels increase home value, so even if you move before payback, you recoup most or all of your investment through a higher sale price. Homes with solar typically sell faster than comparable homes without solar.
