The complete Green Future guide to U.S. residential solar — bills, contracts, batteries, pricing structure, NEM 3.0, federal incentives after the §25D sunset, PPA/Lease traps, installer vetting, and every industry trick that makes solar harder to understand than it should be.

Solar System Basics
After this chapter you will not be intimidated by sales jargon: the three core components, the grid-tied vs off-grid vs hybrid trade-off, how to read battery capacity numbers, and what actually keeps running during an outage.
Warranties and Maintenance
Three layers of warranty, the workmanship layer that actually determines your 20-year experience, the fine print on monthly-fee plans and non-transferable clauses, and how to keep a system alive after the installer goes bankrupt — this chapter takes apart the marketing version of "25-year warranty."
Choosing Your Installer & Equipment
Why bankruptcies among the biggest installers keep accelerating, why "premium American brand" equipment can't even compete on the global market, and most importantly — a seven-point vetting checklist you should run through before any contract gets signed.
Federal Incentives in 2026 — The Real Picture
The OBBBA signed in July 2025 ended the residential 30% federal credit (§25D) early. This chapter explains which incentives still exist in 2026 — the §48E commercial credit, MACRS depreciation, HEEHRA rebates, SRECs — and which have permanently gone away.
California Policy — NEM 3.0 in Depth
NEM 3.0 changed everything. The NEM 2.0 logic — "size 1:1 to annual usage", "more annual production is better", "sell back for profit" — is now obsolete. This chapter lays out four hard design rules under NEM 3.0, plus a counter-intuitive but correct option: Non-export.
Solar Policy Outside NEM 3.0 States
California isn't the only model. Rules differ dramatically across states, and payback periods range from 3 to 15 years. This chapter divides U.S. states into a four-quadrant grid — by export price and by whether net metering is mandatory — so you can think state by state.
PPA / Lease ("Free Install") Contract Traps
"Zero-down solar" in the U.S. market is almost always a PPA or Lease. This chapter exposes the real 25-year cost (you end up paying 5× the system's market price), the year-over-year escalator, auto-renewal clauses, sale-of-home liabilities, class-action waivers, the hell that is NEM 3.0 + PPA combined, and finally what to do if you already signed.
Payback and ROI
Seven variables drive payback period. NEM 3.0 California is 5–7 years; other states range 3–14. This chapter gives concrete numbers, including: how to borrow the commercial ITC via a Prepaid PPA now that the residential credit is gone, whether a $150/month bill justifies solar, and EV charging economics.
Installation Process
From "get your bill" to "system running normally," the full project is 8–16 weeks. This chapter walks through the eight key milestones, the seven must-check items before signing, and why you must never energize the system before receiving PTO.
Solar for ADUs and New Construction
California requires solar on new homes and most newly built detached ADUs. This chapter covers minimum capacity rules, meter planning, why conduit routing has to happen before drywall, and how to coordinate roof vent placement with your builder.
Buying and Selling Homes with Solar
U.S. families stay in the same home for 13.2 years on average. When buying a solar-equipped home, what do you check? What if the seller won't hand over documents? Which install years make the system worth less than zero? Why a PPA home is a liability — addressed in order.
Must Read: Mindset and Common Mistakes
Never trust verbal sales promises. Treat solar as a financial product, not a consumer purchase. Why "the system depreciates" is a mistaken frame. Why "the expensive part isn't solar — it's the financial packaging." How to spot third-party sales reps and shell companies.
Decision Checklist
The entire guide compressed into a single checklist. Run through every box before signing.
DIY Solar
DIY is legal in many jurisdictions, but the bar is higher than most people realize. This chapter covers UL certification, permit, inspection, and the safety risks of working with 240V — plus a seven-step DIY workflow.
