The Short Answer
For most homeowners with decent roofs and $150+/month electric bills, yes—solar is worth it. Typical payback is 6-10 years, with 25-year savings of $30,000-$80,000 depending on your utility and incentives.
But "most" isn't "all." There are real situations where solar doesn't make financial sense. The key is knowing which category you're in.
When Solar IS Worth It
You're Likely a Good Candidate If:
| Factor | Good for Solar |
|---|---|
| Electric bill | $150+/month |
| Utility net metering | Full retail or >$0.08/kWh export |
| Roof condition | 15+ years life remaining, good sun exposure |
| Ownership plans | Staying 7+ years |
| Roof direction | South, southwest, or west facing |
| Shading | Minimal (no large trees blocking roof) |
Solar Works Especially Well When:
- High electric rates: $0.20+/kWh (CA, NY, MA, CT, etc.)
- Strong incentives: Illinois SRECs, MA SMART, NY state credit
- Good utility: Full net metering like ComEd, National Grid
- Rising rates: Most utilities increase rates 3-5% annually
- Environmental priority: Want to reduce carbon footprint regardless of ROI
When Solar ISN'T Worth It
Skip Solar (or Wait) If:
| Factor | Problem |
|---|---|
| Electric bill under $75/month | System too small to be cost-effective |
| Roof needs replacement | Replace roof first (removing panels costs $1,000+) |
| Heavy shading | Trees or buildings blocking sun = low production |
| Moving in <5 years | May not recoup costs; complicates sale |
| SRP or hostile utility | Demand charges and $0.02/kWh exports kill economics |
| Very low rates (<$0.10/kWh) | Hard to beat cheap electricity |
Red Flags in Your Situation:
- Roof over 15 years old: You'll pay $1,500+ to remove/reinstall panels for roof replacement
- North-facing roof: 30-40% less production than south-facing
- HOA restrictions: Some HOAs make solar difficult or impossible
- Complex roof shape: Many planes/dormers = higher install cost, less space
- Renting: Can't install; consider community solar instead
The Real Math (2026)
Typical Scenario: Average American Home
| Assumption | Value |
|---|---|
| Monthly electric bill | $175 |
| System size needed | 8 kW |
| System cost (installed) | $24,000 |
| State/local incentives | -$2,000 (varies widely) |
| Net cost | $22,000 |
| Year 1 savings | $1,800-$2,200 |
| Payback period | 10-12 years |
| 25-year savings | $35,000-$50,000 |
Note: With the federal 25D credit gone, homeowner-purchased systems have longer payback than pre-2026. PPA/lease options still benefit from the 30% 48E credit through 2027, making them more attractive for many buyers.
What Affects Your Numbers
- Utility: Full retail net metering = 2-3 year faster payback
- State incentives: IL SRECs can cut payback by 50%
- Electric rates: Every $0.05/kWh difference = $500-800/year
- Roof orientation: South-facing = 15-25% more production
- Local install costs: CA and NY cost 20-40% more than national average
How to Decide
Step 1: Check the Basics
- Is your roof in good shape (10+ years remaining)?
- Do you own your home?
- Is your electric bill over $100/month?
- Do you plan to stay 5+ years?
If all yes, solar is worth exploring. If any no, think carefully.
Step 2: Look Up Your Utility
Your utility matters more than your state. Check our utility guides to understand your net metering policy. Full retail net metering = great. Export rates under $0.05/kWh = challenging.
Step 3: Get Multiple Quotes
Prices vary 30-50% between installers for the same system. Get at least 3 quotes. Compare price per watt, not just total cost.
Step 4: Run the Numbers
Calculate your simple payback: System cost ÷ Year 1 savings = years to payback. If under 12 years, usually worth it. If over 15 years, probably not (unless environmental motivation).
