The top solar companies for 2016 in residential PV

top residential solar companies

In an industry that now employs well over 200,000 people, it can be difficult to sort through the thousands of solar installation companies that are active in the U.S. in 2017. EnergySage has compiled rankings of top solar contractors across the country on both the national and local level to help homeowners find solar companies near you.

For our national top 20 ranking, we pulled residential data from Solar Power World’s most recent report on the U.S. installer landscape. For the local ranking, we used our own EnergySage installer quality formula to determine the top 10 from our installer database of over 400 vetted installers. Though the top three for national residential solar installers were the same as many years before it, there were many new faces in the top 20 overall, exemplifying the competition and volatility of this industry.

There are a number of new leaders in residential rooftop solar. For example, Zia Energy made the top five in terms of installed MW of PV after not even breaking the top 200 the year before. Eight of the top 20 installers hail from California, the undisputed top state in the U.S. for installed solar, with a surprising second spot held by New Jersey with three of the top 20 residential companies.

The vicissitudes of market share can be attributed to a number of things that have been confirmed by customer activity on the EnergySage Solar Marketplace:

  1. Customers are price shopping more, which means that installers are forced to offer lower prices and thus some companies are going out of business.
  2. The lease model has begun to die out for residential solar. Companies that live and die by third party financing packages have struggled, providing an opportunity for new installers to thrive.
  3. Online platforms like EnergySage are now allowing customers to easily find local installers  rather than just the typical national giants that control more than half of PV market share. Our data has shown that smaller local installers typically offer lower bids than the bigger players in solar.

Comparing the top solar installers by market share and by quality rating

In any free market with strong competition, there will be some dynamic of smaller businesses finding ways to differentiate themselves from the large corporations seeking to monopolize the industry. In the case of solar, it appears that the age of the small local installer has arrived. Homeowners considering solar often find that going with a local contractor for their rooftop installation can be more practical in terms of maintenance and warranty and has historically been more affordable due to the lower prices offered by these smaller companies. With that in mind, we ranked the ten best local EnergySage-approved solar installers in the United States.

Our ranking for the best installers on EnergySage combines favorable review rating, quality of equipment, business accreditation and engagement with customers to generate an overall quality ranking. Similarly to the national ranking by Solar Power World, California came out on top with two of the top 10 installers hailing from the Golden State. No other lead installers notched duplicate states. It’s notable that the only two solar companies to make both Solar Power World’s national top list and our local quality ranking were SolarUnion and Direct Energy Solar.

Solar prices on EnergySage are typically 15-20% lower than in the industry overall as a result of the small players offering lower bids because of the nature of a price auction. On EnergySage, installers compete for your business and don’t typically inflate prices on a national level like some of the industry leaders, which brings us to our…

Three Tips for Solar Shoppers

  1. Homeowners who get multiple quotes save 10% or more

    As with any big ticket purchase, shopping for a solar panel installation takes a lot of research and consideration, including a thorough review of the companies in your area. A recent report by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) recommended that consumers compare as many solar options as possible to avoid paying inflated prices offered by the large installers in the solar industry.

    To find the smaller contractors that typically offer lower prices, you’ll need to use an installer network like EnergySage. You can receive free quotes from vetted installers local to you when you register your property on our Solar Marketplace – homeowners who get 3 or more quotes can expect to save $5,000 to $10,000 on their solar panel installation.

  2. The biggest installers typically don’t offer the best price

    The bigger isn’t always better mantra is one of the main reasons we strongly encourage homeowners to consider all of their solar options, not just the brands large enough to pay for the most advertising. A recent report by the U.S. government found that large installers are $2,000 to $5,000 more expensive than small solar companies. If you have offers from some of the big installers in solar, make sure you compare those bids with quotes from local installers to ensure you don’t overpay for solar.

  3. Comparing all your equipment options is just as important

    National-scale installers don’t just offer higher prices – they also tend to have fewer solar equipment options, which can have a significant impact on your system’s electricity production. By collecting a diverse array of solar bids, you can compare costs and savings based on the different equipment packages available to you.

    There are multiple variables to consider when seeking out the best solar panels on the market. While certain panels will have higher efficiency ratings than others, investing in top-of-the-line solar equipment doesn’t always result in higher savings. The only way to find the “sweet spot” for your property is to evaluate quotes with varying equipment and financing offers.

    I.m in Canada, and all the information provided is geared to the US market, and that’s OK, but have you any information for Canadian Solar enthusiasts?

    Per my mortgage lender. If I am interested in installing solar, I should be looking at U.S. solar companies that are a large National company. Can you please provide any names of National solar companies.?
    Thank You.
