Choosing a solar installer in Portland isn’t just about finding the lowest price. It’s about finding a company that designs the right system for your home, does quality work, stands behind its installation, and can help when something goes wrong.
The best way to compare solar companies is to ask the same questions of each installer. You’ll get a clearer picture of what you’re paying for, who’s responsible for the work, and what kind of support you can expect long after installation.
Here are seven questions worth asking before signing a contract.
1. Who Will Actually Install My Solar Panels?
Not every solar company uses its own installation crews. Some rely on subcontractors, which means the people selling you a system may not be the people installing it.
That’s not automatically a problem. But you should know who’s doing the work and who’s accountable for the results.
Questions to ask:
Does your company use its own installers or subcontractors?
Are your installers licensed and manufacturer-certified?
Who supervises the installation?
Who takes responsibility if something goes wrong?
What A&R Solar does: Our residential systems are installed by our own employees, including licensed electricians and manufacturer-certified professionals. We don’t subcontract our solar installations.
We also use equipment from manufacturers vetted by our in-house research and development team.
When you’re comparing Portland solar installers, ask about the people who will actually be working on your home, not just the brands of equipment they’re installing.
2. What Solar Installation Warranties Are Included?
Solar warranties can sound impressive until you need to use one.
Equipment warranties and workmanship warranties aren’t the same thing. A manufacturer’s warranty addresses covered equipment issues, while an installer’s workmanship warranty addresses covered problems with the installation itself.
Ask each installer to explain what is covered, how long coverage lasts, and who handles a claim.
Questions to ask:
How long is your workmanship warranty?
Who handles equipment warranty claims?
Is replacement labor covered?
Do you guarantee how much electricity my system will produce?
What happens if the company goes out of business?
What A&R Solar offers:
10-year workmanship warranty: Covers defects in workmanship, materials, and construction.
10-year Perfect Guarantee: If your system underperforms, A&R Solar refunds 110% of the production shortfall’s value, subject to the guarantee’s terms.
2-year replacement labor coverage: Covers replacement labor if equipment fails during the first two years, under the applicable terms.
These protections are available to A&R Solar’s Oregon residential customers.
Don’t compare warranty lengths alone. Compare what they actually cover, what they exclude, and who will be there to honor them.
3. Who Handles Solar Panel Service and Repairs After Installation?
This question deserves more attention than it usually gets.
Solar systems are designed to operate over many years, but equipment can sometimes need troubleshooting, repairs, or replacement. Before choosing an installer, find out what happens when you need help.
Questions to ask:
Does your company have its own service department?
Who do I contact if my system stops producing electricity?
Do you service systems installed by other companies?
How are service calls and warranty repairs handled?
Am I responsible for monitoring my system?
What A&R Solar does: We have our own in-house solar service team serving the region from Vancouver, Washington, through Portland, Salem, Corvallis, and Eugene.
Our technicians service A&R Solar installations as well as systems installed by other companies.
Homeowners monitor their systems through the manufacturer’s app and by reviewing their utility bills. When something isn’t working correctly, our service department is available to help diagnose and address the problem.
That distinction matters. An installer that also maintains and repairs solar systems can remain a resource long after the original project is complete.
4. Will My Solar System Be Custom-Designed for My Home?
Your home isn’t identical to your neighbor’s, and your solar system shouldn’t be either.
A good proposal should explain why the installer recommends a particular system size, equipment configuration, and expected electricity production.
If you’re comparing proposals, look beyond the total number of panels.
Questions to ask:
Will you evaluate my roof and shading before finalizing the design?
How do you determine the right system size?
What assumptions go into your production estimates?
How will my current electricity usage influence the design?
Can I include battery storage or add it later?
What A&R Solar does: We don’t use cookie-cutter solar designs.
We provide a free site assessment that evaluates roof conditions and shading. Our proposals include a customized system design, estimated annual electricity production, and projected financial savings.
Our team can also design solar-plus-battery systems or add battery storage to an existing solar installation. When roof work is necessary, we coordinate with roofing contractors.
If you’re considering energy storage, you can explore residential solar battery backup options as part of your planning.
A well-designed system starts with understanding your home, not simply filling available roof space with panels.
5. How Do I Compare Portland Solar Installation Quotes?
The least expensive solar quote isn’t always the best value. But a higher price doesn’t automatically mean better workmanship, either.
The important thing is understanding what each proposal includes.
When comparing solar installation quotes, pay attention to:
System size and production: Are the installers recommending comparable systems?
Equipment: What manufacturers and components are included?
Installation: Who performs the work, and what is included in the quoted price?
Warranties: What equipment, labor, and workmanship protections are provided?
Service: Who will help if something goes wrong after installation?
Financial assumptions: What incentives, fees, and projected savings are included?
Ask each company to walk you through its proposal. If two quotes differ significantly, find out why before assuming either one is the better deal.
What A&R Solar does: We provide itemized proposals showing equipment, installation costs, incentives, and financing details. We don’t charge dealer fees or hidden financing fees.
We also partner with credit unions and leasing providers to offer homeowners different ways to pay for their systems.
If you’re starting to compare options, our Portland solar installation page explains how to get started with a free, no-obligation consultation and customized proposal.
The goal isn’t simply to find the cheapest system. It’s to understand the value you’re getting for your investment.
6. What Solar Incentives and Financing Options Are Available in Oregon?
Incentives and financing can make a meaningful difference in how you evaluate a solar proposal. But it’s important to understand what’s actually available and what assumptions have been built into your estimate.
Questions to ask:
Which solar or battery incentives might apply to my project?
Do I qualify for them?
Are they included in the quoted price or shown separately?
What financing or leasing options are available?
What fees or other costs should I expect?
How were my projected savings calculated?
What A&R Solar does: We help Portland-area homeowners identify available solar and battery incentives and incorporate applicable incentives into financial proposals.
We also work with credit union and leasing partners to provide payment options.
You can review our solar incentives information as a starting point.
Don’t make a purchasing decision based on an incentive or savings estimate you don’t understand. Ask your installer to explain the numbers.
7. How Do I Know the Solar Company Will Be Around to Support Me?
A solar installation is a long-term investment. It’s reasonable to ask about the company behind it.
Online reviews, customer references, years in business, and ongoing service capabilities can all help you evaluate an installer.
Questions to ask:
How long have you been in business?
Can I speak with previous customers?
Can you show me completed residential projects?
Who will manage my project?
Who do I contact after installation?
What kind of ongoing service does your company provide?
What A&R Solar does: We’ve been in business for nearly 20 years. We’re employee-owned and a Certified B Corporation.
Every residential project has a dedicated project manager, and our team coordinates the process from permitting and utility coordination through installation, inspections, and system activation.
We also provide customer references, and you can explore our residential solar project portfolio and Google reviews.
Our in-house service department supports homeowners after installation, including customers whose systems were installed by other solar companies.
Years in business alone don’t guarantee a good experience. But a company’s track record, customer feedback, and willingness to stand behind its work are all worth considering.
What Are the Red Flags When Choosing a Solar Installer?
Even if a proposal looks good on paper, certain warning signs deserve a closer look.
Be cautious if an installer:
Pressures you to sign before you’re ready.
Won’t explain how your system was sized or how production was estimated.
Makes savings promises without showing the assumptions.
Provides vague or incomplete warranty information.
Can’t explain who will install or service the system.
Avoids giving you clear financing terms.
Won’t provide references or examples of completed work.
None of these automatically proves a company will do poor work. But they should prompt more questions before you commit.
A trustworthy installer should be willing to explain its recommendations, discuss your concerns, and give you time to make an informed decision.
Choosing the Right Portland Solar Installer Comes Down to Trust and Accountability
When you’re deciding how to choose a solar installer in Portland, look beyond the equipment and the price.
Ask who’s doing the work. Understand the warranties. Find out who handles service after installation. And make sure the system is designed for your home and your goals.
Compare written proposals, check references, and don’t hesitate to ask questions.
The right solar company should make you feel more informed as the process moves forward, not more pressured.
