Without question national solar installers such as SolarCity (now Tesla), SunRun, Sungevity, and SunPower deserve significant credit for the proliferation of residential solar. From 2012 to 2016 residential solar grew by more than 50% annually, and the top 5 installers have more than 50% market share. They used aggressive marketing campaigns and third party financing products to make average Americans (with FICO scores 680+) comfortable with rooftop solar. However, recently Andrew Bebe beautifully explained why the “long tail” (small regional solar installers, roofers, plumbers, electricians, general contractors) will dominate residential solar in the future. Independent contractors should be very confident their solar installation businesses are competitive with national solar installers and that their businesses are the future of residential solar.

1) Cost & Quality

For the majority of installs, the most important factors are Cost & Quality (economics). Independent installers have an advantage over national installer’s economics. Both independent installers and national installers are using tier-1 Asian Poly, SolarEdge/Enphase, and racking systems that protect roof warranties. In addition, independent solar installers have great access to high-efficiency modules such as Panasonic and LG that cost less than Sunpower. The biggest difference in value-add is that independent installers can complete their installs for less money.

Since the module price drop, independent solar installers across the country do not have issues selling systems for less than $3.30/w (dependent upon roof type and module); installation costs are consistently below $2.75/w. However, according to SunRun’s Q3 2016 financials, the average cost per watt is $3.37/w. Before Tesla's merger with SolarCity, they achieved an installed cost of $3.18/w. While Vivint Solar’s cost was below SunRun’s at $2.85/w, it will consistently cost them about 10% more per watt than an independent installer. The main reason is marketing and overhead. In Q3 2016, both companies spent more than $.50/w on customer acquisition to fund several aggressive marketing strategies. Due to a slightly more complex business model from third party ownership financing products, their overhead will be higher and it has been higher by approximately $.20/w than independent installers. While anything is possible, it seems difficult for national installers to overcome these costs challenges. It is not surprising that previous national installers such as Verengo, One Roof, and NRG Home Solar have gone bankrupt or exited residential solar. Sungevity had their merger canceled and have recently gone through another round of layoffs.  

2) Service

Independent installers should always win big with service. They are known and trusted professionals in their respective communities and potential solar customers quickly know their name and face. Because they are familiar with local authorities having jurisdiction (AHJ), they know how to navigate the interconnection process as efficiently as possible. If there ever was a service issue, the homeowner will have their cell phone and they can attend to the installation immediately. It is much more difficult for a national installer to provide this high level of service and develop a personal relationship with the installer. Involving a national installer will require communication with multiple layers and it will be difficult to match a local installer’s communication. A national installer will take longer to interconnect the system and Sungevity acknowledged that their average install time (sale to system installation) averaged 90 days.   

3) Financing

One of the most interesting predictions for 2017 is there will be more residential loans than residential leases. Homeowners--that have enough tax liability--save significantly more with loans than a lease and they are available across the country, unlike third party ownership. While national installers generally had the advantage with PPAs and leases, it is an equal playing field with loan and PACE products. Mosaic and GreenSky are two of the most popular loan providers for independent contractors and they handle Tesla and SunRun’s loan product as well. They offer an 18-month interest only 20-year and 12-year loan with ~5% and ~3% APR that comes with a varying dealer fee. Independent installers can also more fluidly work with the homeowner to find a financing product that better fits their needs. They can compare multiple loan options and also explore PACE, HELOCs, and Mortgage Refis. Since the same financial institutions are providing loans for both national and local installers, there is no benefit for the national installer. It is also likely local installers will use multiple financing products and they can work with potential solar customers to find the optimal financing solution.   

4) What about Storage?

Storage without a doubt will be critical for residential solar in the future. While Tesla definitely has the best name in the market with their PowerWall, independent contractors have access to great battery alternatives. Products such as GS Battery, BMZ, and SimpliPhi do not have the same name recognition as Tesla, but their Levelized Cost of Energy are comparable and, more importantly, they are readily available to install.

Although it may get overlooked, independent contractors can prepare elegant sales proposals efficiently with programs like Energy Toolbase. National installers have IT departments and have allocated resources to create sales proposals. These proposals are important marketing materials because they allow the homeowner to calculate their savings and understand their systems. While national installers have more resources to develop sales proposals, independent contractors can deliver the same proposal. Energy Toolbase helps solar contractors accurately forecast savings, especially with complex and/or new rate tariffs. Again, the sales proposal is another tool or feature that would previously offer a national installer an inherent advantage but now there’s no difference. 

While some homeowners will prefer national installers, and there will always be homeowners that independent contractors can’t reach, independent contractors should not fear a national installer in their hometown. Instead, they should leverage the demand generated and be ready to shine amongst the competition.
