5 Strategies to Choose the Right Solar Panel Installer

Shares

As solar energy explodes in popularity, there are more solar installation crews mounting solar panels on rooftops and tinkering with home electrical panels. Having the right solar panel installer can really make or break the experience of going solar.

When improperly installed, roof leaks are one of the most common complaints from solar homeowners. By contrast, solar systems can be installed in ways that don’t void roof warranties and actually help protect the roof from the elements. I’ve seen homes where the solar panels protected the roof from hail damage and the panels remain unscathed.

The technical expertise, solar equipment quality and solar system warranties all vary widely by the installer. The good news is that there are many reputable solar installation companies across the country to choose from. Here are some things to look for when finding the winners.

1. NABCEP-Certification Installer

The North American Board of Certified Energy Practitioners certifies energy installers, including solar PV technicians. The requirements include passing a written test and having a certain amount of solar installation field experience. Although certification doesn’t guarantee good workmanship, it does ensure a certain level of knowledge and experience. Ideally, your solar installation will be overseen by a NABCEP-certified professional or, even better, have a NABCEP-certified crew member on the job.

2. Good Company Reputation

When looking for a solar panel installer, find one with a successful track record. If you have friends and acquaintances with a solar system, find out if they were happy with their installer.

Online consumer reviews are another way to find out more about a company. Solar Reviews is a useful source of information on solar installers and equipment, based on consumer reviews.

It’s also good to find out if the solar installer outsources its labor. If so, the quality of the installation might be less predictable.

3. Ideal Solar Equipment Options

In most areas, there are at least two reputable solar companies to choose from. Getting multiple bids can improve the quality of the finished product and possibly the out-of-pocket cost. For example, some installers take a one-size-fits-all approach to solar system design, while another company might customize your installation based on your needs, goals and the property. If installing your solar system is more complicated, it is especially helpful to find an installer that customizes your solar system design by selecting the best equipment and installation approach.

For help comparing options, EnergySage is funded by the Department of Energy and provides a suite of online tools and resources that assist consumers in researching and shopping for solar. Another service, UnderstandSolar, links solar shoppers to top-rated solar installers for personalized solar estimates. Various installers commonly offer different technology options to their customers. Perhaps you are willing to splurge on some sleek solar panels because they have such a long warranty or you want an inverter with backup power supply when the grid is down. By speaking with different solar panel installers, you can familiarize yourself with the different equipment choices.

4. Comprehensive Solar System Warranty

Various solar equipment comes with different manufacturer warranties, and installers often guarantee their work as well. Because solar is a pretty hefty investment, it is wise to protect yourself with a warranty.

Workmanship warranties can vary widely between installers but often last between one to 10 years. The solar equipment has additional warranties that are provided by the manufacturer. Solar panels typically have an equipment guarantee for a certain length of time in addition to a power performance guarantee for energy production. Other components, such as the inverter, can have very short warranties of just a few years or ones that last 25 years. Make sure you are clear about warranties before signing a contract with a solar panel installer.

5. Turnaround Time

Because solar energy has exploded in popularity in recent years, many solar installers have jam-packed installation schedules for months. If you want a solar system installed soon, it is wise to ask what their schedule looks like before signing a contract.

Keep in mind that the timing of when the solar system is installed impacts the availability of the 30 percent federal tax credit. For example, if you install a solar system in February, you need to wait much longer to use the tax credit than if you installed the system in November.
