How to Actually Compare
Most homeowners get confused because installer quotes look wildly different. Here's what matters (in order):
- Price per watt installed — the true apples-to-apples number. Divide total price by system size in watts.
- Panel brand + wattage per panel — 400W panels vs 550W panels change the roof footprint significantly.
- Inverter architecture — string, microinverter, or optimizer — determines monitoring granularity and shading tolerance.
- Warranty terms — installer's workmanship warranty (separate from panel/inverter manufacturer warranty).
- Financing details — APR on loans, escalator on leases, dealer fees hidden in loan pricing.
- Company reputation — Google reviews, BBB rating, years in business, NABCEP certification.
Common Mistakes to Avoid
- "Limited time offer" pressure tactics — real solar quotes are valid 30+ days
- Quote higher than $4.00/watt installed (2026 average is $3.00-3.50)
- Vague equipment brands ("premium panels" without naming manufacturer + model)
- Missing production estimate (kWh/year expected output)
- No shading analysis (Aurora Solar / Helioscope PDF)
- Financing "dealer fee" that isn't itemized (often 15-25% hidden markup)
- Lease/PPA with an escalator clause above 2.5%/year

Solar in 2026 is a proven, mature technology with strong ROI in most US markets. The single biggest driver of your total savings is who you hire, not which panel brand you pick. Get 3 quotes, compare on the criteria above, and choose the installer that fits your budget AND has strong reviews.
