Compare Solar Installer Quotes
The difference between the cheapest and most expensive solar quote on the same home averages $4,000-$7,000 in 2026. That gap makes comparing quotes the single highest-value activity in your solar buying process — and it takes less than 10 minutes.
What to Compare in Solar Quotes
Not all solar quotes are created equal. Price per watt is the standard metric for comparing system costs — divide the total pre-incentive price by total wattage. In 2026, competitive residential pricing falls between $2.50-$3.50/watt. Anything below $2.25/watt warrants scrutiny (cheap equipment or corners cut on installation), and anything above $4.00/watt needs strong justification (premium panels like SunPower Maxeon, complex roof, or extensive electrical work).
Beyond price, compare these factors across your quotes: panel efficiency and manufacturer warranty (25-year production guarantees from Tier 1 manufacturers like SunPower, REC, LG, Canadian Solar, or Qcells), inverter type (microinverters from Enphase vs. string inverters from SolarEdge — each has tradeoffs), workmanship warranty (separate from equipment — look for 10+ years), and projected annual production (should be within 5% across quotes for the same roof).
Red Flags in Solar Quotes
Watch for quotes that inflate production estimates to make savings look better. Ask what degradation rate and solar irradiance assumptions they used — reputable installers use NREL PVWatts data. Also be wary of quotes that bundle financing costs into the “system price” without breaking out the interest separately. And if a quote doesn’t name the specific panel and inverter models, that’s a sign the installer plans to use whatever’s cheapest at installation time.
How to Get Comparable Quotes
Request quotes from at least 3 installers for the same system size and similar equipment tier. Specify that you want quotes using Tier 1 panels and either Enphase microinverters or SolarEdge optimizers — this ensures you’re comparing apples to apples. Ask each installer to provide a production estimate using PVWatts, not proprietary models.
