Solar is having a moment in Ottawa. Between rising hydro rates and provincial rebate programs, more homeowners in Kanata, Barrhaven, Orleans and the core are getting quotes on rooftop systems. To help narrow the search, we looked at public review platforms, Better Business Bureau records, company websites and aggregator sites like SolarQuotes.ca to pull together this list of installers actually operating in the Ottawa region right now. We could verify solid detail on eight companies, so that is what you will find below rather than a padded top ten.
1. True Beacon Solar
Area: Ottawa and Eastern Ontario · Specialty: turnkey residential and commercial solar with battery integration · Rating: 5.0 on Google (153 reviews, via SolarQuotes.ca)
True Beacon's systems are designed by a Master Electrician and installed by licensed electricians and certified solar installers, and the company is a certified installer for Enphase, SolarEdge, Sol-Ark, Tesla and FranklinWH equipment. It offers full workmanship and manufacturer warranties along with 24/7 system monitoring, and helps customers navigate Ontario's Home Renovation Savings Program rebates. With the highest review count of any Ottawa installer we found, it suits homeowners who want a full-service, tech-forward install.
2. FIG Solar & Battery Storage
Area: Cumberland to Carleton Place, greater Ottawa region · Specialty: residential and commercial solar and battery storage · Rating: 5.0 on Google (38 reviews, via SolarQuotes.ca) · Since: 2009
Founded by Mike Gauthier and Dave Brisebois, FIG Solar (which also operates as Execon Roofing and Solar) has been installing systems in the Ottawa area since 2009 and says it has delivered over 20 million watts of clean energy across Canada. Customers on review platforms point to its knowledge of local hydro programs and responsiveness to questions. It is a solid pick for homeowners who want an installer with a long local track record and roofing expertise alongside solar.
3. Kajk Constructors Inc
Area: Ottawa and the wider Ottawa region · Specialty: residential and commercial solar plus green retrofits · Rating: 5.0 on Google (38 reviews, via SolarQuotes.ca) · Since: 2016
Kajk Constructors is a full-service design-and-build contractor for solar and green retrofits, and it won the 2025 Ottawa Consumer Choice Award in the Solar Energy Systems category. Reviews consistently mention smooth, on-time installations and staff who walk customers through every step of the process, from equipment selection to permitting. It is a good fit for homeowners who want a contractor comfortable handling both the electrical and construction sides of a project.
4. Dtech Services and Solutions Inc.
Area: Ottawa and roughly a 200km radius, including Nepean, Kanata and Orleans · Specialty: solar panels, inverters and high-capacity energy storage · Rating: 4.9 on Google (125 reviews) · Since: BBB A+ accredited as of August 2025
Dtech is a licensed and insured outfit that pairs solar installs with real-time monitoring technology and handles the rebate paperwork on a customer's behalf. It also offers 24/7 emergency service, which sets it apart from installers who only handle the initial build. With one of the higher verified review counts on this list, it works well for homeowners who want responsive support after the panels go up, not just during installation.
5. Quadra Solar Corp
Area: Gloucester and the greater Ottawa area · Specialty: design, installation and maintenance for residential, commercial and utility-scale solar · Since: 1999
Quadra Power, doing business as Quadra Solar, has been in the Ottawa solar market since 1999 and holds BBB accreditation. Customer feedback describes a low-pressure sales process, transparent quotes and installations completed on schedule. Its span from residential rooftops to utility-scale projects makes it a reasonable option for homeowners who also want a company with experience on larger commercial jobs.
6. Ottawa Solar Power Inc
Area: Eastern Ontario and Western Quebec, from Kanata to Kemptville · Specialty: residential and commercial solar, off-grid systems, net metering and battery storage · Rating: 4.2 on Google (30 reviews, via SolarQuotes.ca) · Since: 1996
Ottawa Solar Power says it has installed more than 1,000 systems in the region since 1996, making it one of the longest-running names on this list. A HomeStars review describes a system still running well after five years with only one panel needing replacement, which the company handled directly. It is worth a call for homeowners who want an installer with decades of experience with off-grid and net metering setups specifically.
7. Consumers Energy Services
Area: Ottawa and other Canadian markets · Specialty: solar installation alongside heat pumps, HVAC and insulation upgrades · Rating: 4.8 on HomeStars (188 reviews) · Since: 2011
Consumers Energy Services bundles solar with broader home energy work, including heat pumps and insulation, and says it has served more than 95,000 Canadian homes since 2011. Its HomeStars rating is built on a large review base relative to most installers on this list. It suits homeowners who are planning a wider home energy retrofit and want one company coordinating solar alongside heating and efficiency upgrades.
8. Sunshine Solar Power
Area: Ottawa · Specialty: residential and commercial solar installation using SolarEdge inverters
Sunshine Solar Power is a smaller, Ottawa-based installer that handles system design and paperwork for customers, working with both Hydro Ottawa and Hydro One. It has far fewer public reviews than the other companies on this list, so treat it as a newer or lower-volume option worth getting a quote from rather than a firm with an established review history. It may suit homeowners who prefer working with a small, local outfit directly.
How We Built This List
This list was compiled from public web sources: company websites, Better Business Bureau listings, Google review aggregators like SolarQuotes.ca, and platforms including HomeStars and Yelp. Nobody on ottown's team tested, visited, or personally verified any of these companies' work. This is not a paid placement and no business on this list is affiliated with ottown or its operator. Ratings and review counts reflect what was visible at the time of research and can change. We could verify solid detail on eight installers rather than ten; a company's absence does not mean it does poor work, only that we could not confirm enough detail about it from public sources. Last reviewed: August 2026.
