If you live in Southern California, you’ve probably noticed your electricity bill creeping higher — even if your usage hasn’t changed. With utilities raising rates year after year, many families are asking:
👉 Is solar actually cheaper than sticking with the utility company?
The short answer: Yes. By a wide margin. Let’s break it down with real numbers and see how solar stacks up against utility power over 25 years.
The Baseline: Average Home Energy Use
For this example, we’ll assume a typical single-family home in Southern California uses about 750 kilowatt-hours (kWh) per month, or 9,000 kWh per year.
Here are the assumptions we’ll use:
Starting utility rate: $0.30/kWh (many TOU rates are even higher)
Annual utility rate increase: 8% (based on California’s recent escalation trends)
Total solar system cost: $28,000 (mid-range system)
Federal solar tax credit (ITC): 30%
Net solar cost after credit: $19,600
Solar financing term: 25 years at ~3.99% APR
Monthly solar payment: ~$105
Annual solar cost: ~$1,260
System production: 100% offset (net metering + optional battery storage)
Year-By-Year Cost Comparison: Solar vs. Utility Power
Year | Utility Rate ($/kWh) | Annual Utility Cost | Solar Payment (Fixed) | Cumulative Utility Cost | Cumulative Solar Cost |
1 | $0.30 | $2,700 | $1,260 | $2,700 | $1,260 |
5 | $0.41 | $3,714 | $1,260 | $16,279 | $6,300 |
10 | $0.60 | $5,395 | $1,260 | $46,991 | $12,600 |
15 | $0.89 | $8,147 | $1,260 | $98,793 | $18,900 |
20 | $1.32 | $12,310 | $1,260 | $181,448 | $25,200 |
25 | $1.96 | $17,583 | $1,260 | $314,306 | $31,500 |
25-Year Comparison
Utility Power Total Cost: ~$314,306
Solar Power Total Cost: ~$31,500
✅ Homeowners save more than $280,000 by going solar.
Even under conservative assumptions, solar beats utility costs — and the gap only grows wider as utility rates climb.
What About Maintenance and Panel Efficiency?
Good question. Here’s what most homeowners experience:
Panel degradation: ~0.5%–1% per year. Modern panels last 30+ years, and this minimal decline is often built into the system design.
Maintenance: Occasional cleaning and inspections, usually under $200/year if outsourced.
Inverter replacement: May be needed around year 12–15, often covered by extended warranties.
Warranties: Most premium systems include a 25-year performance and workmanship warranty.
Even factoring these small costs in, solar still comes out far ahead.
After Year 25: The Free Energy Era
Once your solar system is paid off:
Your panels keep producing free power for another 5–10 years or more.
Utility customers will likely be paying $20,000 per year or more for the same energy.
With a battery, you’ll also enjoy energy independence from grid outages.
Solar isn’t just a bill-saver — it’s a long-term investment in your home and financial stability.
Why Southern California Homeowners Are Choosing Solar
Predictable energy costs instead of volatile utility hikes
Protection under NEM 3.0 with batteries that maximize solar value
Increased resale value (buyers love homes with low or zero energy bills)
Environmental benefits — shrink your carbon footprint
Energy independence — keep the lights on during outages
And with $0-down financing, federal tax credits, and local rebate programs (like SGIP & RSSE), there’s never been a better time to switch.
