Is Solar Still Worth It Under NEM 3.0? A Realistic Analysis
This is the question on every California homeowner's mind: with NEM 3.0 cutting export credits by 75%, is solar still a good investment? Let's look at the numbers honestly.
The Pessimistic View
Critics point out that under NEM 3.0:
- Solar-only systems have longer payback periods (8–10 years vs. 4–6)
- Export credits are worth pennies compared to dollars before
- Battery systems add $10,000–$15,000 to the upfront cost
The Reality Check
Now here's what those critics miss:
- Utility rates have risen 40% since NEM 3.0 launched — The savings from self-consumption have grown dramatically. What you avoid paying matters more than what you get for exports.
- Battery costs have dropped 30% since 2023 — Battery systems that cost $15,000 in 2023 now cost $10,000–$12,000.
- The federal tax credit covers 30% of everything — Solar panels AND batteries qualify for the 30% ITC.
- You're comparing against a moving target — Your alternative isn't cheap electricity. It's PG&E at $0.45/kWh and climbing. Over 25 years, that could be $0.80+/kWh.
Real Scenario: Solar + Battery Under NEM 3.0
For a PG&E customer with a $350/month bill who installs an 8 kW solar system with a 13.5 kWh battery:
- System cost after ITC: ~$22,000
- Annual savings (year 1): ~$3,800
- Payback period: ~5.8 years
- 25-year savings: $95,000–$115,000
- Return on investment: ~400%
What Other Investment Gives You 400% Returns?
Solar isn't just "worth it" — it's one of the best investments a California homeowner can make. The stock market averages 10% annually. Solar delivers 15–20% effective returns, tax-free, with virtually zero risk (the sun will keep shining, and rates will keep rising).
