Pick if: federal contracts, tax-conscious. BEST WARRANTY — Maxeon 40 years (industry leader), Silfab 30 years. Pick if: long-term ownership 25+ years. AVOID 2026: LG Neon — LG EXITED solar 2022. Existing LG warranties honored but NO new manufacturing. Panasonic EverVolt — Panasonic EXITED 2024. REC bought tech but inventory ending 2027. SunPower (legacy) — bankruptcy 2024. Maxeon split-off carries forward (good). Original SunPower service complicated.

Solar panel installed cost 2026 (per watt): TIER 1 PREMIUM (Maxeon, REC Alpha) — $3.80-$4.20/watt installed. Includes panels + microinverters + racking + labor + permits. 8 kW system = $30,400-$33,600. TIER 2 MID-RANGE (Q-Cells, Canadian, JinkoSolar, Trina, LONGi, Silfab) — $3.00-$3.50/watt. 8 kW system = $24,000-$28,000. AFTER INCENTIVES: 8 kW system $25,000 → -30% IRA credit ($7,500) = $17,500 net. Add state rebates: CA $850-$2,000, MA $4,000-$10,000, NY $1,000-$2,000. Effective $13,000-$15,500 for 8 kW after stacking. INSTALLED COST BREAKDOWN: panels 35-40% ($1.10/watt at $3/watt total). Inverters 15-20% ($0.50/watt). Racking 10-15% ($0.40/watt). Labor + electrical 25-30% ($0.85/watt). Permits + interconnection 5-10% ($0.20/watt). PER-PANEL math (typical): 425W panel @ $3.20/watt = $1,360 installed. 20-panel 8.5kW system = $27,200 installed → $19,000 after IRA + state. PAYBACK: typical 7-12 years depending on state electricity rate. CA/HI/MA/NY: 5-7 yr payback. TX/FL/most others: 10-12 yr. WY/ID/UT (cheap electricity): 14-18 yr (rarely worth without state incentives).

Solar panel degradation = annual efficiency loss over time. INDUSTRY STANDARD: 0.5-0.8% per year. After 25 years: ~80-85% original output. Top-tier panels degrade SLOWER. PREMIUM (lowest degradation): Maxeon — 0.25%/yr. After 40 years: still 90%+ original output. Industry-leading. REC Alpha — 0.25%/yr. Same class. Panasonic EverVolt — 0.25%/yr. MID-TIER (good): JinkoSolar Tiger Neo — 0.40%/yr. Trina Vertex — 0.40%/yr. LONGi Hi-MO 7 — 0.40%/yr. STANDARD (acceptable): Q-Cells, Canadian Solar — 0.50-0.55%/yr. After 25 years: ~85% output. WHAT THIS MEANS LONG-TERM: 8 kW system installed 2026 producing 11,500 kWh/yr Year 1: PREMIUM (Maxeon) Year 25 produces 10,800 kWh = 94%. STANDARD (Q-Cells) Year 25 produces 10,000 kWh = 87%. Lifetime difference 25-yr: ~7,000 kWh × $0.16/kWh = $1,120 advantage to premium. NOT JUSTIFY $1.20/watt premium for most homeowners. SECONDARY DEGRADATION FACTORS: (1) HIGH HEAT — desert climates degrade faster (panels rated at 25°C STC, real ops often 50-70°C). Microcracks form. (2) MOISTURE INGRESS — coastal humidity. EVA encapsulant degrades. (3) UV EXPOSURE — laminate yellowing. (4) MICROCRACKS from snow load, wind, hail. CHECK PANEL MANUFACTURER WARRANTY — most guarantee 80%+ output at year 25 (industry standard). Maxeon guarantees 88% at year 40.

Solar manufacturer exits 2022-2024 explained: LG (LG ELECTRONICS) — exited residential solar June 2022 globally. Reasons: (1) couldn't compete on price with Chinese manufacturers (LONGi, Trina, JinkoSolar 30-50% cheaper). (2) LG profitable battery/EV business needed capital. (3) US tariffs against Chinese panels didn't equalize enough. EXISTING WARRANTIES: LG honors 25-year warranties through 2047 via global service centers. New LG panels NOT manufactured. PANASONIC — exited US residential solar 2024. Reasons: (1) US factory closure made costs uncompetitive. (2) Strategic refocus on lithium battery + EV. (3) HIT cell technology licensed elsewhere. EVERVOLT INVENTORY: REC took over manufacturing but Panasonic-branded panels available through 2027. Service stays through manufacturer network. SUNPOWER (LEGACY) — bankruptcy filed 2024. Maxeon (spinoff since 2020) survives + sells panels independently. Original SunPower service contracts — Sunrun acquired residential portfolio and provides service. THESE EXITS LEFT MID-TIER GAP for Q-Cells, Canadian Solar, JinkoSolar to fill 2024-2026. WHO SURVIVED: vertically-integrated manufacturers with battery/EV adjacencies (Hanwha Q-Cells with Hanwha Group, Canadian Solar with battery storage, Maxeon spun-off SunPower). PURE-PLAY solar manufacturers struggle. KEY 2026 CONSEQUENCE: warranty+ existence concerns drive consumers to financially-stable brands. Made-in-USA Q-Cells (Hanwha) Georgia, Silfab Washington, Mission Solar Texas seen as safer bets.

Made-in-USA solar 2026 (IRA Section 45X domestic content): MANUFACTURERS: Q-CELLS Georgia (Dalton, Cartersville) — largest US factory 2026. Hanwha Q-Cells Q.PEAK DUO BLK ML-G11+ has variants. SILFAB Washington (Burlington) — 380-415W panels. MISSION SOLAR Texas (San Antonio) — 380W panels. CANADIAN SOLAR Texas (Mesquite) — coming online 2026. PRICING: Made-in-USA panels typically $0.10-$0.30/watt premium over equivalent Chinese-made. EX: Q-Cells Georgia $3.30/watt vs Q-Cells South Korea $3.20/watt. INCENTIVES THAT JUSTIFY PREMIUM: (1) IRA SECTION 45X DOMESTIC CONTENT BONUS — 10% on top of standard 30% federal credit if Made-in-USA panels + USA inverters (typically Enphase or SolarEdge USA). Total credit becomes 40%. (2) FEDERAL CONTRACTS — Buy America Act requires Made-in-USA. Government installations require these brands. (3) STATE INCENTIVES — some states offer additional rebates for domestic content. (4) GEOPOLITICS — supports US clean energy industrial policy. (5) WARRANTY LOGISTICS — easier service through US-based manufacturers. PURE ROI: $0.20/watt premium × 8 kW = $1,600 extra cost. 10% IRA bonus on full system $25k = $2,500 EXTRA credit. Net advantage $900. WORTH IT for IRA-eligible installs. NOT WORTH IT: cash buyers without tax appetite (no IRA credit usable). Lease/PPA customers (provider claims credit, not you). DECISION: 65-75% of new 2026 residential installs choose USA panels for IRA bonus. Trend accelerating. 2026 Made-in-USA market share doubled from 18% (2023) to 38% (2026).

Solar installer vetting 2026: (1) NABCEP CERTIFICATION — North American Board of Certified Energy Practitioners. Verify at nabcep.org. Indicates technician training. (2) STATE LICENSE — solar typically falls under electrical contractor license. Verify at state contractor board. (3) INSURANCE — workers comp + $1M+ general liability + $2M+ umbrella. Phone verify. (4) MIN 3 REFERENCES — projects 2-5 years old (not just brand new). Drive by, ask homeowners about post-install issues. (5) MANUFACTURER CERTIFICATION — Q-Cells/Maxeon/REC Authorized Installer. Better warranty terms for you. (6) DETAILED PROPOSAL — line items: panel brand+model, inverter brand+model, racking, electrical, warranty terms (25-year manufacturer + 10-year workmanship). (7) PAYMENT SCHEDULE — never >25% upfront, never final >10% before PTO (Permission to Operate). (8) PERMITS HANDLED BY INSTALLER — not your problem. (9) PRODUCTION GUARANTEE — Year 1 production guaranteed in writing. If short, installer pays difference. (10) WARRANTY ON LABOR — minimum 10 years for workmanship. (11) LICENSE/INSURANCE proof in advance — not promises after deposit. AVOID: door-to-door sales (often misleading), offers without site assessment, "fully financed at 0%" usually hides 18-25% interest in price markup. RED FLAGS: high-pressure sales, contracts longer than 7 days to review, "today only" pricing, requesting cash, no website or generic templated website. RESEARCH: EnergySage marketplace gets multiple bids automatically. Reddit r/solar reviews. NREL Solar Database. State Solar Energy Industries Association (SEIA).

Inverter system choice 2026: STRING INVERTERS (cheapest) — 1 central inverter handles all panels. $0.20/watt cost. Pros: simplest, cheapest. Cons: shading on 1 panel reduces ENTIRE STRING output 30-50%. Not ideal for shaded roofs. Brands: SMA, Fronius, Solis. MICROINVERTERS (Enphase IQ8/IQ9) — 1 inverter per panel. $0.40/watt cost. Pros: per-panel monitoring, no single point of failure, optimal in shaded conditions, 25-year warranty matches panels. Cons: 80-100% more expensive than string inverter. Brands: Enphase (90%+ market). POWER OPTIMIZERS (SolarEdge) — central inverter + per-panel optimizer. $0.30/watt cost. Pros: cheaper than micro, retains per-panel monitoring + shading mitigation. Cons: complex topology, 12-year inverter warranty (need replacement before panels). Brands: SolarEdge. RECOMMENDATIONS 2026: ENPHASE MICROINVERTERS — best for most residential 2026. 90%+ of new installs choose microinverter. Match 25-year panel warranty. SOLAREDGE — runner-up. Cheaper but inverter replacement required at year 12-15. STRING INVERTERS — only for unshaded south-facing roofs in cost-sensitive installations. ADVANTAGES OF MICROINVERTERS 2026: (1) Granular monitoring (Enphase app shows each panel performance). (2) Easier to scale up (add panels = add microinverters, no central inverter resize). (3) Battery storage natively integrated (Enphase IQ Battery 5P/10C systems). (4) Made-in-USA option. POWER OPTIMIZER USE CASE: large home (10kW+), heavily shaded multiple-orientation roof, want to spend less than full microinverter setup.
