There is the belief that solar installations are limited to a few companies that only deal in solar. That is not the case as illustrated by the following article that describes the various occupations involved in solar construction.
The primary industry begins with solar contractors, and then branches out to electrical contractors and plumbing contractors. General contractors and roofing contractors are also involved in solar installations. Because solar PV is electrical and solar hot water is plumbing-related, the industry sees a lot of participation from plumbing and electrical contractors.
Solar contractors operate independently or in conjunction with other contractors, such as roofers. Every project is different, so who is involved depends on the size and scope of a project. A typical solar contractor can handle a small residential system from start to finish. A large utility-scale project may involve coordinating with a roofing manufacturer or general contractor.
Companies in this sector employ many electricians, but also plumbers, roofers and general construction labor. Given that every project has unique characteristics, every project requires a slightly different skill set. For photovoltaic, the main skill set is electrical. For larger scale projects, a need for steel or concrete professionals or roofers may present itself.The first step to any installation project is engineering, followed by permitting and procurement and installation.
With so many occupations associated with solar installations the job market is wider in scope than most people realize. Tennessee has enough sunlight to warrant adopting solar both for large farms and distributed solar within our communities. With the price for large installations at prices competing with fossil-fueled power generation, with the advantages of no fuel cost and the environmental benefits – what is stopping our national leaders from promoting this technology? That is a question that only they can answer.
