How to review solar quotes before signing in California

Quick answer

Before signing, compare every proposal against your actual utility bill and your real home assumptions. The most important comparison is not the monthly payment only—it is the full energy-cost picture: proposed charge, monthly utility charges, escalator impact, and transfer/buyout terms.

Before you sign, confirm each of these 12 items

1. Utility territory and rate plan
   Confirm the estimate is based on your current utility and current bill type.
2. Quote type and ownership
   Confirm whether it is a lease, PPA, loan, or cash purchase.
3. Payment schedule and term
   Document payment amount, contract length, first payment timing, and escalation assumptions.
4. Projected remaining utility charges
   Ask how the remaining electric bill is modeled after the system is added.
5. Battery scope (if included)
   Verify whether battery use is for backup, demand response, bill optimization, or all three.
6. Production and production decline
   Confirm expected year-one vs year-n production assumptions and replacement assumptions.
7. System size and component quality
   Confirm panel, inverter, and storage sizing assumptions and warranty terms.
8. Installer and service scope
   Confirm monitoring coverage, maintenance responsibilities, and inverter replacements.
9. Escalator and index risk
   Confirm whether solar payments and utility credits escalate and by how much.
10. Transfer and sell-home process
    Confirm what happens if you sell your home before the contract ends.
11. Buyout, early termination, and resale values
    Confirm whether buyout is available and how termination is priced.
12. Net bill outcome for your usage pattern
    Compare projected net bills in peak-season and shoulder-season scenarios.

Why "cheapest monthly payment" is not enough

Low monthly payment quotes can hide higher total costs if remaining utility charges, escalators, or ownership terms are unclear. A strong comparison includes:

• Remaining utility charges
• Battery assumptions
• Escalation terms
• End-of-term options
• Transfer language

Suggested decision flow

• Collect at least two complete quotes with the same city and utility context.
• Put the same assumptions side-by-side in a simple comparison table.
• Remove any proposal that lacks utility context, remaining charge assumptions, or transfer terms.
• Review final questions with the quote reviewer before signing.

FAQ

Q: Does this mean no savings are possible with solar?
A: Savings are possible in many homes, but online estimates are preliminary. Final numbers depend on usage, roof conditions, shade, utility territory, rate plan, and contract terms.

Q: Should I compare a solar-only quote against a quote with battery storage?
A: No. Compare like-for-like systems. Solar-only and solar-plus-storage have different costs and outcomes.

Q: Can I trust a single quote from one installer?
A: A second quote adds competitive signal, especially around payment, contract language, and battery assumptions.

Next step

Use this checklist, then request a reviewed comparison before signing. If you have two solid proposals, the next safe step is to compare your assumptions on:

• California solar quote comparison page with same utility and usage context: https://californiaenergyhelp.com/california-solar-quote-comparison
• How to review a solar quote guidance from the guide hub: https://californiaenergyhelp.com/california-solar-guides

Do not decide from a single proposal. Compare timing, pricing components, and long-term contract terms first.
