Seattle quote factors
What to factor into your Seattle solar installer quote
Local context that should shape what you quote as a solar installer in Seattle. Marine west coast. Mild winters (rarely below 25°F), cool summers (rarely above 85°F historically, but 2021 heat dome 110°F+), heavy rain (38" annually mostly Oct-May), occasional snow. PNW moss and mildew constant concerns. Mild climate makes heat-pumps highly efficient year-round. Wildfire smoke August-September from California/Oregon/Idaho/BC fires. Atmospheric river events drive flooding.
Washington L&I Electrical License
Washington L&I Electrical Contractor License (EC, EL01 General Journeyman, EL07 Master Electrician) required for solar work. Print L&I license number on every quote and invoice. SDCI won't issue permits to unlicensed contractors.
Per-watt installed cost
Seattle residential and small commercial solar runs $3.20-$4.80 per watt installed ($3,200-$4,800 per kW). Above-average due to Seattle labor, hilly terrain, and complex roof structures. Premium tier (battery storage, smart monitoring, branded panels) $4.20-$5.50 per watt.
Federal ITC + WA State + Seattle incentives
Federal 30% Investment Tax Credit (ITC) applies through 2032 for residential solar and battery storage. Washington State Energy Office and Seattle City Light/PSE offer solar production incentives (varies by program year). Quote ITC and state/utility incentives as lines on net cost; conversion rate doubles when incentives are visible.
Tech-wealth premium tier
Capitol Hill, Madison Park, Queen Anne, Magnolia, Madrona, Mercer Island, Bellevue (Clyde Hill, Yarrow Point, Hunts Point), Bainbridge Island, Sammamish clients expect premium brands (SunPower Maxeon, REC Alpha Pure, Panasonic EVERVOLT) with Enphase IQ or SolarEdge inverters. Quote premium tier at $4.00-$5.50 per watt.
Seattle City Light + PSE net metering
Seattle City Light + Puget Sound Energy offer 1:1 retail-rate net metering for residential solar up to system size. Excellent for Seattle solar economics. State utility on every contract; SCL typically faster interconnection (4-8 weeks) than PSE (6-12 weeks).
Battery storage growing post-grid-events
Seattle battery storage growing fast thanks to grid resilience needs (Pacific Northwest atmospheric river events, ice storms cause outages). Quote battery storage (Tesla Powerwall 3, Enphase IQ Battery, FranklinWH aGate, LG Resu Prime) at $8,500-$24,000 per battery installed. Federal ITC applies to battery storage (30% through 2032).

Seattle metro electricity split between Seattle City Light (City of Seattle proper) and Puget Sound Energy (PSE, suburbs including Bellevue, Kirkland, Redmond, Mercer Island, Bainbridge Island). Both offer 1:1 retail-rate net metering for residential solar up to system size. State utility on every contract; SCL typically faster interconnection (4-8 weeks) than PSE (6-12 weeks).
Yes, growing market. Seattle battery storage growing fast thanks to grid resilience needs (Pacific Northwest atmospheric river events, ice storms cause outages). Quote battery storage (Tesla Powerwall 3, Enphase IQ Battery, FranklinWH aGate, LG Resu Prime) at $8,500-$24,000 per battery installed. Federal ITC applies to battery storage (30% through 2032).
Per kW installed in {YEAR}: $1,200 to $2,500 in the US, £1,200-2,000 in the UK, A$900-1,800 in Australia, R18,000-35,000 in South Africa, and C$2,400-3,800 in Canada. Larger systems get cheaper per-kW due to scale; tier-1 panels and premium inverters push toward the top.
Most 3-bed homes need 5-8kW; 4-bed+ homes with pool or EV need 8-12kW. Look at your last 12 months of electricity bills, divide annual kWh by 1,300 (Australia/SA), 950 (UK/Canada), or 1,200 (US average). That gives kW capacity to offset most of your bill.
Depends on your feed-in tariff. Where FIT is high (Australia historically), batteries have 10-12 year payback; export to grid is more valuable. Where blackouts are common (South Africa) or FIT is low (UK), batteries pay back faster and add resilience. Quote both options.
A standard 5-10kW residential install is 1-2 days on the roof for a 3-person team, plus grid connection paperwork (1-6 weeks depending on utility). Larger systems and commercial installs take 3-7 days.
Site visits and verbal quotes for systems over 4kW are usually free. A detailed shading analysis, structural roof report, and load-flow calc for a 20kW+ commercial system takes 4-8 hours and may be charged $300-1,500. Worth it on large projects.
