How Do I Choose a Solar Installer?
Solar is built to sit on your roof for 25 years or more. That makes choosing an installer less about branding and more about long-term accountability. The real question isn’t just, “Who offers the lowest price?” It’s, “Who can I trust to stand behind this system years from now?”
1. Who actually owns the responsibility?
Not all solar companies are built the same way. Some handle sales, design, and installation under one roof, while others split those roles across different companies or separate legal entities.
This distinction matters because if a problem pops up, you need a single point of responsibility. In a split-responsibility setup, getting a fix can sometimes result in a fragmented response where different parties point to hardware defects or wiring issues as someone else’s problem.
Our perspective: We’ve found that service calls often take longer when two different companies have to coordinate who pays for the truck to come out to your house.
What to clarify:
- Contract ownership: Which company signs the contract and takes legal responsibility for the entire project?
- The resolution path: If a roof leak or electrical fault occurs, who is contractually obligated to show up and fix it?
2. How is the installation actually managed?
A reliable system depends on consistent oversight, which usually comes down to how a company manages its crews.
Some companies use subcontracted labor. This allows them to grow quickly, but it can lead to inconsistent standards because the quality of work may vary depending on which crew is assigned to your roof that day. Other companies use in-house teams, which typically allows for more centralized training and oversight.
Our perspective: Quality issues, like minor leaks or production drops, rarely show up on day one; they usually surface years later due to small errors in how connections were handled.
What to clarify:
- Are licensed electricians directly supervising the critical electrical connections on-site?
- Is there a formal, documented sign-off protocol for every project before the power is turned on?
3. What does the workmanship warranty really cover?
Solar proposals often highlight 25-year hardware warranties from the manufacturer, but those are separate from the installer’s workmanship coverage.
Manufacturer warranties cover the parts, like the panels or the inverter. They do not usually cover the labor to remove a failed part, the shipping costs, or the repair of a roof penetration. Most disputes happen at this “labor gap” between the hardware maker and the installer.
What to clarify:
- If an inverter fails, who pays for the labor to swap it out?
- Who is specifically responsible for roof leak repairs under the workmanship warranty?
4. How is future service handled?
Over a 25-year lifespan, some level of service is statistically likely—whether it’s an equipment update or a minor repair. The relevant question is how the company is staffed to handle it.
Some installers maintain dedicated service departments with their own technicians. Others rely on installation crews to handle repairs only when there is a gap in the “new install” schedule. If a company is focused solely on new sales, your repair might be delayed until a crew becomes available.
Our perspective: We often see that companies without a dedicated service wing struggle to prioritize repairs during the busy summer installation season.
5. Is the company built for the long term?
A solar system should outlive short business cycles. You want to ensure the company responsible for your warranty will still be there to answer the phone in fifteen years.
Instability often happens when a company prioritizes rapid growth over building the internal service depth needed to support existing customers.
What to clarify:
- Longevity: How long has the company operated under its current name and ownership?
- Local presence: Do they maintain a permanent local office and staff in your region?
What this decision comes down to
Choosing an installer is a decision about structural accountability. It is not just about who installs the panels, but who is organized and staffed to stand behind that work for the next two decades. Next steps
Take the time to understand the company behind your investment. Ask clear questions. Pay attention to how responsibility is defined, and make sure you know who you’ll be working with years from now — not just on installation day.
