Solar Installers

Once you’ve made the decision to install a rooftop solar system to reduce your electric bill and decrease your environmental footprint, the next step is choosing a reputable solar installer. As solar energy is gaining popularity on homes and businesses, the prevalence of installation companies is increasing to meet the demand. But not all solar installers can provide the expertise, high-quality workmanship, and reliable customer service to ensure your system performs efficiently to provide the highest return on investment.

Here are some suggestions to help you find the best installation company:

Recommendations and Reviews

A good way to begin the search is by asking family members, friends, neighbors and co-workers about their experience with local installers. Then read consumer reviews of installers who serve your area. Company reviews by actual customers are a great way to determine which companies have provided satisfactory experiences, and which have generated complaints. While a high rating indicates a company is more likely to provide a positive customer experience, keep in mind that an occasional bad review is bound to happen. What the solar installer did to correct a negative experience can provide insight into their level of integrity and their dedication to customer satisfaction. California customer Ian Hernandez was encouraged by Renova Solar's consumer reviews, and chose the Palm Desert, Calif. installer for his rooftop solar system. "The reason I went with [Renova] was because of their high-rated reviews and the great quality of work that people had to say about them," Hernandez recalled. 

Multiple Quotes 

Request a free quote from not one, but several installers that serve your area. Online quote request forms take into account your local electricity rates and your energy usage (based on your utility bill) so you can decide how much energy you wish to offset. Aside from comparing prices, a quote request can reveal how responsive a company is, and may foreshadow how a solar project will progress. Another reason Hernandez chose Renova Solar was because they called him the next day, whereas the other companies took three days—even a week—to reply. “One thing that caught my attention right away was Renova’s quick response,” Hernandez said. “It showed they had a more personal interest in their customers than the other companies did.” 

Solar Panel Brand and Design

The solar installer should be able to explain the different brands of solar panels they install, along with the benefits and downfalls of each. The installer should listen carefully to your specific solar needs and concerns, and then recommend the panel that would best fit your lifestyle, budget, aesthetic requirements and desired electric output.

Monocrystalline panels are the black, original solar panel made from a single cell of pure silicon that makes them more efficient, more difficult to manufacture and more expensive than polycrystalline silicon panels. Comprised of multiple crystals, the blue polycrystalline solar panels absorb less sunlight so they are less efficient than monocrystalline panels—but not by that much. As technology improves, the efficiency gap continues to close.

If your roof has sufficient space for a solar array, then a solar panel’s peak efficiency shouldn’t be your primary consideration. Your solar system’s performance will also depend on the angle of sunlight (depending on roof orientation and panel tilt), along with the type of inverter you choose.  

Panel and Inverter Warranties

The power output or performance warranty on solar panels often lasts between 25 and 35 years. This warranty covers repairs of the actual silicon cells, should their electric production fall below a given percentage. A workmanship or product warranty may also be offered, which covers other components of the panel, such as the glass, backing and laminate. Although damage to these parts of your solar panel is rare, it can result in significant losses in electric generation. Inverters are the element most susceptible to breakdown, as they continually work to convert the collected DC power into AC power you can use in your home. Inverter warranties generally last between five and 10 years on central inverters and 25 years for microinverters.  

Certifications

The right certifications can help assure that your solar array is installed carefully and correctly. In the U.S. market, the North American Board of Certified Energy Practitioners (NABCEP) is one of the most reputable certification programs for solar PV and solar heating installers—and a good credential to look for. The Pre-Screened Solar Pro is a new, consumer-driven accreditation that signifies an installer has met strict eligibility requirements for years in business, has achieved an excellent customer rating, has earned a minimum number of independent reviews and has passed a thorough background check. The Better Business Bureau (BBB) is another organization that can help reveal a company’s credibility by disclosing any formal complaints that have been filed against the installer. 

Service Commitment and References

Assess the installer’s solar knowledge, helpfulness, ability to explain technical information in simple terms, level of professionalism and whether he or she responded in a timely fashion. 

References are also important. The right solar power company will be able to answer your questions, while making you feel comfortable about the decision to work with them. Aside from reading independent reviews from other customers, don’t be afraid to ask your potential installer for a handful of references. After talking to some past customers of Jamar Power, Steve Naiman decided to move forward with his rooftop array from the Santee, Calif. installer. “It was not a high pressure sale,” Naiman said. “They showed me what they had available, and I had seen what a lot of other companies had available—I liked [Jamar Power’s] product a lot better. I asked for some referrals and contacted two of the three people. They had positive things to say.” 

Financing Options

In 2012, the average cost of a residential solar system in the U.S. was $20,000. Since every homeowner isn't able to make this kind of upfront investment, various financing options have become available. Your solar installer should be able to fully explain all of your payment choices, so you that you can decide which one is best for your situation. One reason Solar Solution AZ owner Robert Watson III won the bid from Arizona customer Greg Attaway was that his proposal included numbers to illustrate the different financing scenarios. "[Watson] came prepared," Attaway said. "He laid everything out; worked out what the costs were going to be and printed it out."

Both a power-purchase agreement (PPA) and a solar lease make it possible to go solar with little, or even no money down. In both of these payment options, a third party owns and maintains your solar system and the terms often vary from 10 to 25 years. With a PPA, you pay for the energy the panels produce (similar to paying your current electric bill) and with solar leasing, you pay a fee to lease the equipment that comprises your solar system. Home equity loans are another financing option, and are becoming more popular as solar is proving to add value to a home.

There are other financing avenues that differ by state, such as Property Assessed Clean Energy (PACE) financing that makes a solar system more affordable by allowing property owners to borrow money from their local governments for energy-efficiency improvements—spreading the system’s cost over a longer period of time. Solar Renewable Energy Credits (SRECs) are available in states that have adopted a Renewable Portfolio Standard (RPS), requiring utility companies to purchase renewable energy credits (that include the specification of solar energy) to offset their fossil fuel production. 

Going solar is a big commitment. So it’s important to find a company that you can trust to provide you with accurate and thorough information to choose the best solar panel, inverter and size of your system, while installing your array with quality and precision—and then performing timely maintenance as needed.
