Blossom Solar

What Blossom Solar does

Blossom Solar LLC is a privately held Washington State solar installation company founded in 2017, headquartered in Everett with operational offices in Arlington and Renton. The company designs, sells, and installs photovoltaic solar systems for residential and commercial customers across Washington, using a stack built primarily on Enphase microinverters paired with Silfab, REC, and Solaria panels. Battery backup offerings span Enphase IQ Battery 5P/10C, Tesla Powerwall 3, and FranklinWH aPower 2/S, with grid-interactive features including net metering at a 1:1 utility credit ratio and the PSE Flex Batteries demand-response program.

The business model is one-time project revenue: custom-engineered systems priced via quote rather than published rates, with approximately 43% of customers financing through partner credit unions (Verity Credit Union). Go-to-market is sales-led via inside Sales & Design Consultants, supported by free 15-minute consultations, a structured $500-for-both-sides referral program, SEO/content marketing, and earned media from Seattle Times Best in the PNW recognition (three consecutive years). In 2024, Blossom expanded into adjacent home services — residential HVAC (Midea, Mitsubishi, RunTru by Trane heat pumps and furnaces) and electrical services (Generac generators, EV chargers, panel upgrades, tenant improvements) — to capture incremental wallet share from existing customers. The company holds Enphase Platinum, Tesla Energy, FranklinWH, Silfab Elite, and SPAN authorized installer certifications, and its co-founder Cole Anderson remains directly involved in field installations.

Broad incumbents

• Sunrun: Largest US residential solar installer offering solar leases, PPAs, and battery installations nationwide. Comparable to Blossom in residential solar + battery focus but operates at national scale with different financing and customer-acquisition model.
• Tesla Energy: Sells and installs Solar Roof and Powerwall directly to homeowners, competing with Blossom's residential solar + battery offering. Vertically integrated manufacturer that is also a Blossom supplier (Tesla Powerwall 3), making it both a peer and a partner.

Emerging players

• Palmetto Solar: Clean energy technology company offering residential solar, battery, and heat pump installations across multiple US states, with proprietary software for system design. Comparable in residential solar + electrification bundle and direct-to-consumer sales motion.

Direct peers

• Momentum Solar: Direct-to-consumer residential solar installer operating across multiple US states with in-house installation crews. Highly comparable to Blossom in sales-led GTM, residential focus, and full-stack solar + battery offering.
• Trinity Solar: One of the largest privately held US residential solar installers operating primarily in the Northeast and Mid-Atlantic. Comparable regional-to-multi-state installer profile with a sales-led residential model.
• Blue Raven Solar: Residential solar installer acquired by SunPower; offers in-house financing and direct sales across multiple states. Closely comparable to Blossom in customer segment, sales-led motion, and solar-as-core focus.
• SunPower: National residential and commercial solar installer offering DC-optimized systems and battery storage. Closely comparable to Blossom in target customer (residential homeowners) and product bundle (panels + battery), though operating at much greater scale.

Regional players

• A&R Solar: Portland-based residential and commercial solar installer serving Oregon and southwest Washington. Closely comparable regional installer with similar residential focus, custom system design, and local-roots positioning.
• Puget Sound Solar: Long-standing Seattle-based residential and commercial solar installer serving the Puget Sound region. Most direct local competitor to Blossom, sharing the same Washington geography, residential focus, and microinverter-based product stack.

Others

• Enphase Energy: Manufacturer of microinverters and home batteries and Blossom's primary technology supplier. Relevant as a strategic enabler (Enphase Platinum Installer) and as the underlying technology standard for Blossom's installations and monitoring app.
