Pros bring skills and experience to a project that a one-time installer does not have. The majority of installers have years—sometimes decades—of experience designing and installing systems. They know what works and what doesn’t, and understand the subtleties of system design and changes in the National Electrical Code. They have relationships with building inspectors and equipment distributors, and have established peer networks for situations where even they may need advice. Professionals also can provide you with guidance and a streamlined process for navigating the typically complicated processes of applying for, receiving, and maximizing any available financial incentives. They may also offer system financing and leasing options that can minimize or even eliminate your up-front investment.
Solar contractors are specialized, but they are no different than any other building or trade professional. They offer products and services that enable the smooth implementation of high-quality systems. That said, keep in mind that the level of experience, support, and professionalism can vary greatly between contractors. If your system will be professionally installed, find someone whose experience you trust, and verify it by checking both customer and business references. Spending some time on the Internet researching customer feedback on potential contractors can be helpful.
