What is the difference between Simplis vs Solar Installer?

AspectSimplisSolar Installer
Required CredentialsTypically no formal certifications requiredOften requires certifications like NABCEP
Work EnvironmentPrimarily office-based, project planningOn-site installation and maintenance
Industry UsageDesigns and plans solar systemsBuilds and installs solar panels

While Simplis focuses on designing and planning solar energy systems, Solar Installers are responsible for the physical installation and maintenance of solar panels. Both roles are essential in the solar industry, but they require different skills and certifications. Simplis professionals typically work in an office setting, whereas Solar Installers are hands-on, working on-site. Understanding these differences helps job seekers find the right role in the solar energy sector.
