Best Solar Installers

Inland Empire

Guasti Solar

Guasti Solar stands out for one reason: they still show up a decade later. We found 11 reviewers praising post-installation support with zero complaints, a pattern almost unheard of in solar. One homeowner whose inverter died eight years after installation got warranty troubleshooting at no charge.

Nippon Energy

Nippon Energy earned one of the strongest post-sale support scores we've seen. One customer shared how Navin kept answering questions a full year after installation, even during evening hours. Another mentioned that the owner personally called to apologize for a minor issue before the crew had even

Sunshine Saves

Sunshine Saves stands out for something rare in solar: installers who actually listen. We analyzed dozens of reviews and found a consistent pattern of reps (Jamie, Ryan, Xavier) who build systems around what you need rather than what's easiest to sell. One homeowner researched solar for months befor

Blalock Electric & Solar

Blalock Electric & Solar earned near-perfect scores in workmanship and project management across over a hundred installations. We found just five negative comments about installation quality, while 107 reviewers specifically praised the crews' attention to detail. One homeowner watched installers co

Triple Line Solar

Triple Line Solar has earned a perfect workmanship record across dozens of installations, and we found one story that captures why. A homeowner bought a house with Jeff's seven-year-old panels already on it, discovered a leak, and watched multiple roofers try to blame the solar and upsell a full roo

Option One Solar

Option One Solar will call you when something breaks before you even notice it. We analyzed hundreds of reviews and found a company whose post-install support sets them apart from industry competitors who disappear after cashing your check. One customer's system went offline and received a proactive

RAD Electric Renewable Energy

RAD Electric does exactly what you need, when you need it, without the usual contractor runaround. We analyzed dozens of customer stories and found a pattern: Andrew shows up on short notice, fixes the problem in one visit, and charges less than competitors quoted for the same work. One homeowner ca

T & G Roofing and Solar

T & G earned our strongest recommendation after we analyzed more than a hundred customer stories. We found a contractor whose 20-year roof installations still perform leak-free today, and whose owner personally inspects jobs before signing off. One customer called back after a 2015 install when Janu

Switch Solutions

Switch Solutions stands out for doing something rare in solar: the same rep who sold you the system actually stays involved through installation and beyond. We analyzed nearly a hundred reviews and found 28 that specifically praised Sasha for showing up on installation day to answer questions, handl

All Temperature Air is a safe bet for HVAC work, though it's not a company we'd champion as exceptional. We found a consistent pattern of owner Anthony and his team showing up fast when systems fail. One family endured a broken AC through a heat wave, only to have another company ghost them until Mo

Solar Optimum is a safe bet for solar. We analyzed thousands of reviews and found the company delivers quality work at competitive prices, but you'll need patience for communication hiccups. One homeowner watched their neighbor's install so closely they chose Solar Optimum themselves after comparing

Solarflexion is a reliable parts supplier, not a solar installer. We found them because homeowners kept mentioning fast turnarounds on replacement inverters and racking components that local contractors couldn't source. One California customer spent weeks hunting for Fronius inverter replacements be

Transform Power checks the essential boxes. We analyzed nearly a hundred reviews and couldn't find a single complaint about shoddy work or a team that ghosted after installation. One homeowner watched owner Jared drive out between other jobs to replace a failed inverter within 48 hours, more than a

REP Solar delivers clean installations by crews who show up on time and finish fast. We analyzed dozens of reviews and found 34 customers praising the quality of the work itself, with installers Rudy and Eduardo mentioned by name in multiple accounts for neat conduit runs and panels installed in a s

Todd Solar Engineering is a solid choice if you need pool solar work, but steer clear if you're after rooftop photovoltaic panels. We analyzed dozens of customer stories spanning a decade and found two wildly different companies depending on what you're buying. For pool solar installations and repai

ElectriCare delivers solid installs without drama. We analyzed their work and found 44 reviewers calling out clean, professional workmanship and zero complaints about damaged roofs or sloppy conduit runs. When a panel dropped to 5% output a year after installation, the company responded to a Sunday

Underline Energy Concepts delivers solid work, but communication gaps can derail the experience. We found 68 reviews describing smooth installations with courteous crews who vacuumed up roof nails and arrived on time, and one homeowner told us installers brought a portable toilet for a multi-day rer

SoCal Energy Group delivers solid work with responsive reps who stick around after the sale. We analyzed hundreds of reviews and found a pattern that sets them apart: sales consultants give out personal cell numbers and actually answer them. One customer called his rep when an AC unit died the day a

Solar Watt Solutions won't wow you with slick marketing, but they'll get your system up and running fast and stand behind it for years. We found 64 reviews describing solid workmanship and zero complaints about the installation crew cutting corners. One homeowner called Dave eight years after instal

Martinez Electrical Services will solve your problem, but don't expect a seamless experience. We found 21 reviews describing fast turnarounds and reasonable pricing, and when Juan Carlos comes through, he really does: one homeowner watched him return after dark with the correct part to fix a lightin

Nunez Electric and Solar does solid work, but Paul Nunez himself is the entire operation. We analyzed dozens of reviews and found the same pattern: when Paul shows up, diagnoses the problem, and completes the work himself, customers rave about his technical skill and fair pricing. One homeowner watc

Pacific Sun Technologies is a safe bet, but they're not breaking new ground. We analyzed reviews spanning installations from 2013 through 2025 and found consistent delivery on the basics: installations wrap up in one to two days, the crew patches stucco and cleans up before leaving, and if a panel f

Van Lund Roofing handles the basics well but struggles with responsiveness. We analyzed dozens of reviews and found a clear split: if you get on the schedule, the crew delivers solid work and clean job sites (47 reviewers specifically praised workmanship, and multiple customers hired James twice). O

Calzona Solar is a reliable installer for hands-on homeowners who value price and quality work over polish. We found an owner who shows up early, completes installs in a day when other contractors dragged on for months, and coordinates directly with roofers to flash every roof penetration properly.

GRID Alternatives isn't your typical solar installer. They're a nonprofit that trains volunteers and job seekers to install panels on low-income homes at no cost to the homeowner. We analyzed hundreds of reviews and found the model delivers real results. One homeowner in San Diego paid zero out of p
