How to Hire the Best Solar Panel Installation Contractor

After digging through all the research, you've decided to finally install solar panels. This exciting switch can greatly reduce energy bills, but how do you find the right solar panel installation contractor? A solar panel installer should have licensing and insurance to legally practice in your state. When you're hiring a pro, look for one with at least three years of experience in their field and get multiple quotes from pros before making your decision.

What Services Does a Solar Panel Installation Contractor Offer?

There’s a lot to consider when going solar, but a solar panel installation contractor can help you navigate the project from beginning to end. Typical services they provide include:

• Analyzing the power usage of your home and calculating how many panels you need

• Designing your solar panel layout with input from designers and engineers

• Assessing your roof condition before installation

• Mounting your panels in the optimal location and at the right angle

• Financing your solar project

• Maintenance, including regular solar panel cleaning

Can You Install Solar Panels Yourself? 

Solar panel installation is a complex task, so most DIYers can’t take on this project. However, if you’re well-versed in electrical work, you may want to tackle smaller projects like installing solar on a travel trailer or installing panels on the ground. Installing panels on a roof, especially one to power your entire home, requires knowledge and experience to do so safely.

One of the hardest parts of a DIY job can be sourcing the solar panels and all the necessary components. You can find online vendors or contact local solar companies to see if they’ll sell you the units you need.

How Much Does Solar Panel Installation Cost? 

Solar panel installation costs $27,150 on average, with actual costs depending on your solar needs and the type of panel you choose. There are financing and leasing options for solar that make it affordable for most homeowners. Regardless of how you pay, you can look forward to saving on future electricity costs.

Tips for Hiring a Solar Panel Installer

A successful solar panel installation requires a bit of preparation. Here’s how you can find the best installer. 

1. Plan Your Solar Panel Installation Project for Accurate Quotes

You’ll want to have a few details squared away before asking potential contractors for project quotes. Ask these questions to ensure you cover all solar panel installation cost factors before signing on that dotted line:

• Will the solar panel be on the grid or off the grid?

• How much power will I need? 

• Where will the solar panel be placed (e.g., roof, ground, etc.)?

• Do I need solar panels or solar shingles?

• What will be the inverter type?

Get at least three quotes from different solar panel pros, and ask what goes into their pricing model so you can make the best choice for your budget.

2. Check Your Solar Installer’s Qualifications and References

Not all states require a solar contractor to be licensed, so check your state solar certification and licensing requirements. We recommend hiring an installer certified by the North American Board of Certified Energy Practitioners (NABCEP), which provides quality credential programs for solar panel installation professionals. Also, hire a contractor who is insured to protect you from liability. 

Ask your potential hire for any references and reach out to them. Ask the contacts detailed questions about their experience with the pro, like if the installer started the project on time, their communication style, or if there were any issues throughout the installation process.

3. Interview Pros and Get Multiple Quotes 

Once you’ve pinpointed qualified solar panel installers in your area with good reviews, you should call and interview them. Find out their installation process, available financing options, and potential project timelines.

You should get at least three quotes. When reviewing the quotes, look carefully at the details. Know what’s included and what’s not so you can accurately compare the quotes. The most affordable option isn’t necessarily the best, and the same can be said for the most expensive quote. You’ll want to find a contractor who fits your needs and provides excellent customer service from the get-go.

4. Get a Contract and Arrange Payments With Your Solar Panel Installer

Never work without a contract. Here’s what yours should include:

• Down payment: A down payment is normal and necessary to secure materials.

• Payment structure: Set up an agreed-upon schedule so there are no surprises.

• Final payment: This should be the last installment and only be released once they've completed the job to your satisfaction.

• Terms and conditions: These include warranty information, cancellation policy, and all the legal fine print. Read it all before signing.

• Schedule: Know when your project will start and when you can expect it to be completed.

• Business license number and contact information: Confirm your contractor’s information before signing.

5. Keep Records of Your Solar Installation Project

Keeping records of your project can come in handy should an issue arise. Here’s what you should track:

• Any receipts for materials (if your contractor is purchasing them, ask for copies)

• Hours worked, especially if this is how your labor is being calculated

• Progress photos throughout the project

• Detailed records of daily progress if the project starts to fall behind schedule

6. Know Your Rights and Avoid Solar Panel Installation Scams

If your project is abandoned or not completed to the terms listed in the contract, you have the right to withhold the final payment. If a contractor is harassing you for payment, report them to your local consumer affairs office.

Finally, look out for scams. Scammers may pressure you into starting a project before you're ready. They may also pose as government officials or offer you big discounts for your installation. If something feels off, it's better to take some time to vet your solar installer before moving forward.

Questions to Ask Your Solar Panel Installer

Here’s a list of some of the questions to ask your pro:

• Do you handle all documentation and necessary paperwork? Working with your utility company can be complicated and time-consuming. Consider working with a contractor who handles all the detailed paperwork for you.

• Who secures the permits? Typically, the permit process is included in the labor cost. If this is the case, you can ask what portion of your total costs are for permitting.

• Do you subcontract work? It’s helpful to know if the contractor will be the one installing your panels.

• Have you worked with my local utility company? Every utility company has different rules about how home solar energy systems can connect. It’s beneficial to work with a contractor who has experience with your specific company.

Choosing the Right Solar Panel Installer 

Choosing the right solar panel installer can make the difference between a system that lasts for 20 to 25 years or longer with no major issues and a problematic installation. A poor job can cause roof leaks or the system to go down frequently. 

Take your time when choosing your installer. Don’t focus on just the price or their availability. Go with the company that earns your trust and has a proven track record. Some companies are superb at sales but don’t follow through with the same quality of service when it comes to installation. Ask all the questions you have and hold off on signing a contract until you’re absolutely sure of your final choice.

After the Work Is Finished

Once your solar panels are installed, take some time to examine the final result. This involves inspecting the panels and seeing how they power your home. If you can’t access the installation site, ask your contractor to take pictures for you. 

Once you’re happy with the project results, make the final payment. If possible, leave your contractor a positive online review and agree to be a future reference for them.
