  • Solar installers don’t spend most of their time on the roof working with the actual solar panels. Instead, a majority of their time is spent assembling, positioning, and attaching the racking systems that fix the solar panels in place.

  • About one out of every five residential solar systems have roofing problems caused by inexperienced solar installation companies—problems that will often lead to roof leaks over time.

  • Over three quarters (77.6%) of all [solar] employers cite difficulty finding candidates with any training specific to the position, and a similar number (77.9%) report difficulty finding candidates with any relevant work experience.

  • Construction productivity has been flat for decades… In manufacturing, by contrast, productivity has nearly doubled over the same period, and continuous improvement has been the norm.

  • It may take a year or two of heavy rain, but eventually an improperly installed rooftop solar mounting system will make itself known. … The costs of such a failure for the liable solar installer are more than financial.

  • There is no indication that the high levels of difficulty finding and hiring qualified solar workers seen today will lessen without some form of industry change.

  • As more companies enter the market for solar projects, competition intensifies—and profits narrow. … To maintain attractive margins, the best players will drive down the cost of building a plant faster than the industry average, allowing them to grow.
