Solar installer vs. electrician: who do you need?
A solar installer typically designs and installs the solar system, while a licensed electrician handles electrical integration, wiring, disconnects, inverters, panel work, and code-compliant grid connection. Many solar projects involve both roles.
What a solar installer usually handles
A solar installer — also called a PV (photovoltaic) installer — is responsible for the physical solar system: solar system design and production modeling; panel and equipment selection; placement and orientation planning for optimal energy yield; racking and mounting system coordination and installation; system sizing based on your energy usage and roof or ground space; solar equipment installation and mechanical assembly; and overall project planning and permitting coordination. NABCEP PV Installation Professional certification is the recognized credential for this role.
What an electrician usually handles
A licensed electrician handles the AC-side electrical integration of a solar system: wiring from panels to inverter; DC combiner box wiring; inverter connection and configuration; AC disconnect installation; connection from the inverter to your home's electrical panel (or a dedicated solar circuit); production meter and monitoring equipment; code compliance with NEC Article 690; grid interconnection support and utility paperwork; and electrical integration of the solar system with the building's existing wiring.
When batteries or panel upgrades may be involved
Solar projects frequently expand in scope when battery storage or panel upgrades are added. Battery systems (Tesla Powerwall, Enphase IQ Battery, Franklin WH) require a critical loads subpanel, a bidirectional inverter or gateway, and careful integration with the existing panel — all of which are licensed electrical work. Older homes with 100-amp panels may need a panel upgrade before a solar system can be interconnected. If your project includes solar plus battery plus a panel upgrade, the electrical scope is substantial and should be scoped by a licensed solar electrician before you sign any contracts.
