Solar is the highest-pressure sales environment in home services. Big promises, complex financing, long contracts. San Diego homeowners are routinely locked into 25-year agreements on systems that were poorly sized or overpriced. Send us yours first.

Important: Solar proposals are more complex than most home service quotes. We'll review the system size, production estimates, price per watt, financing terms, escalator clauses, and NEM 3.0 billing implications — all the things that are easy to miss when a salesperson is in your living room.

📋 What a Solid Solar Proposal Should Include

  • Panel brand, model, and wattage — not just "Tier 1 panels"
  • Inverter brand and model (string vs. microinverter vs. power optimizer)
  • System size in kilowatts (kW) clearly stated
  • Estimated annual production in kilowatt-hours (kWh)
  • Your last 12 months' actual usage used to size the system
  • Price per watt (total cost before incentives ÷ system kW)
  • Federal tax credit (30% ITC) clearly broken out — you receive this, not the installer
  • NEM 3.0 billing explanation — how SDG&E will compensate your excess power
  • Net cost after incentives stated clearly
  • If financed: interest rate, loan term, escalator clause (if any), and who holds the loan
  • If leased: lease term, annual escalator %, buyout terms, and transfer terms when selling home
  • Warranty: panels (25 yr), inverter (10–25 yr), workmanship (10 yr minimum)
  • Timeline from signing to permission-to-operate (PTO)
  • CA CSLB license number for installing contractor

⚠️ Red Flags That Should Make You Pause

  • "Today-only" pricing — legitimate solar installers don't need pressure tactics
  • System sized larger than your usage requires — oversizing means paying for production you can't use under NEM 3.0
  • No explanation of NEM 3.0 and how it dramatically changed solar economics in San Diego
  • Lease with high annual escalator (2%+ per year can erase savings over time)
  • Loan with deferred interest (PACE/HERO loans have traps — read carefully)
  • Production estimates significantly above national norms for your roof angle/shading
  • Salesperson cannot explain exactly how your SDG&E bill will change
  • Panel brand you can't find independently verified reviews for
  • No workmanship warranty offered, or less than 5 years
  • Price per watt above $3.50 before incentives (San Diego market average is ~$2.80–$3.30 in 2026)

🔄 How SideGuy Reviews Your Solar Proposal

  1. Send us the full proposal — PDF preferred. The key numbers are: system size (kW), total cost, estimated production (kWh/year), and financing terms.
  2. We check system sizing vs. your usage — under NEM 3.0, oversizing is a common way to inflate the contract value while delivering less actual benefit to you.
  3. We calculate true price per watt — and compare to San Diego market rates for 2026.
  4. We review financing terms — especially escalator clauses, deferred interest risks, and home sale transfer complications if leasing.
  5. We explain NEM 3.0 implications — this 2023 policy change fundamentally changed solar ROI in San Diego. Many proposals still use old math.
  6. We give you specific questions — things to ask the installer that will tell you immediately whether they're being straight with you.

❓ Frequently Asked Questions

What's a fair price for solar in San Diego in 2026?

For a typical 6–8 kW system: $17,000–$26,000 before the 30% federal tax credit, which brings it to $12,000–$18,000 net. Price per watt before incentives should be around $2.80–$3.30. Above $3.50/watt is high for San Diego unless there's complex roofing or electrical work involved.

What changed with NEM 3.0 and does it affect my decision?

Yes, significantly. Under NEM 3.0 (effective April 2023 for new systems), SDG&E pays you much less for excess solar you export to the grid — roughly 75% less than under NEM 2.0. This affects payback period and optimal system sizing. Many pre-NEM 3.0 pitch decks still circulate — make sure your proposal reflects current economics.

Should I buy or lease solar in San Diego?

Buy if you can, in most cases. You get the 30% federal tax credit, full ownership, and cleaner home sale. Leases transfer as liens on the home and can complicate sale. Loans are middle-ground. The right answer depends on your tax situation and plans — send us your proposal and we'll walk through it.

The salesperson said I'd have $0 electric bill. Is that true?

Rarely fully accurate under NEM 3.0. You'll have a minimum monthly connection fee ($10–$15/month with SDG&E regardless of production) and your savings depend heavily on your usage patterns. "Zero bill" claims should be backed by specific numbers in the proposal — if they aren't, ask why.

What's a solar lease escalator clause and why does it matter?

A lease escalator increases your monthly payment each year by a set percentage (often 2–3%). Over 20+ years, this can mean your "affordable" solar lease becomes more expensive than buying power from SDG&E. Always ask for the payment schedule for all 20–25 years, not just year one.

Is this review really free?

Yes. We don't install solar, don't take referral fees from installers, and don't have anything to gain from pointing you toward or away from any company. We exist to give you honest guidance before a major financial decision.

💰 How Contractors Structure Solar Installation Pricing in San Diego

Permit Costs

All solar installations in San Diego require a permit and SDGE interconnection approval. Battery storage systems require additional fire/electrical inspection under California Fire Code. Budget $300–$1,500 for permit fees on mid-range projects. Permit fees are a legitimate hard cost — any quote that omits them is understating the true project cost.

Labor Bands

$80–$150/hr. A typical 7kW system installation takes 1–2 days for a 2-person crew.. On a typical project, labor accounts for 30–50% of total quoted cost. The specific crew skill level, travel distance, and San Diego's high cost of living all push labor rates above national averages.

Material Costs

Solar panels (per watt): $0.30–$0.70 material cost. Inverter: $1,500–$6,000. Battery bank (10kWh): $8,000–$14,000 installed. Material prices in San Diego track 8–15% above national averages due to supply chain routing and local fuel costs. Ask for a materials breakdown — understanding what you're paying for reduces negotiating friction.

Contractor Margin

Solar contractors operate at 25–45% gross margin. Equipment markup is often 30–50% above wholesale cost. Ask for equipment brand/model to verify market pricing. Margin itself is not a problem — contractors need it to sustain a licensed, insured business. The problem is when margin is hidden inside inflated line items rather than stated transparently.

⚠️ Common Red Flags in San Diego Solar Installation Quotes

📄 CSLB License Verification — Do This Before You Sign Anything

Every contractor doing work in California must hold a current, active license from the Contractors State License Board (CSLB). For solar installation work, the relevant classification is C-46 (Solar Contractor) — or Class B with C-10 (Electrical) for solar + electrical scope.

The CSLB lookup takes 60 seconds and shows: current license status, bond amount, workers' compensation status, and any enforcement history. A contractor who discourages you from verifying their license is a contractor worth reconsidering.

What to verify: license number matches the contractor entity on your contract, license status is "Active," bond is current, and workers' comp is in force (or contractor has a valid exemption).

🎯 When the Lowest Quote Is Not the Best Quote

The lowest bid on a solar installation project in San Diego is not always — and not usually — the best value. Low bids typically mean one of three things: scope has been omitted, permits are being skipped, or the materials specification is lower-grade than the competing bids.

A complete, honest bid that is 15% higher than the lowest quote is almost always the better financial decision. The cost of a failed inspection, a scope dispute, or unpermitted work discovered during a future home sale typically exceeds the initial bid difference by 3–5x.

The right question is not "who is cheapest?" but "whose quote is most complete?" A bid that accounts for permits, proper disposal, licensed subcontractors, and a written warranty is protecting your investment — not inflating it.

What this is

AI automation tools are everywhere right now — but most vendors oversell what they can actually deliver for a small business. The honest answer is that the right tool depends entirely on your existing workflow, team size, and how much time you're losing to manual tasks today.

Common Mistake

['Starting with the most complex use case instead of the simplest.', 'Buying a platform before running a 30-day single-use-case pilot.', 'Not involving the staff who will actually use it in the selection process.']
