Selecting a Solar Installer

Before buying any equipment, you must decide whether you, the property owner, or a licensed contractor will install the solar energy system. Keep in mind that solar systems require a working knowledge of electrical wiring (electric systems have the potential of producing dangerous shocks). Also, if owner-installed, all permits, interconnection paperwork, inspections, and rebate paperwork will need to be completed by the owner-installer. Along with system design and installation, a qualified installer will assist with related paperwork. To qualify for state rebates for PV systems, a contractor will need to have an A, B, C-10, or C-46 license (self-installers receive smaller rebates). Finding a qualified installer for your solar electric or solar thermal system is an important part of the process. The Solar Resources page, which lists Humboldt County solar thermal and solar electric installers, should aid in this process. The RCEA does not endorse any of these installers, and recommends that consumers seek references and investigate installer experience.

How can I select the right solar installer?

• Check with the CEC for a list of system sellers and installers, and to ask for referrals.
• Contact the Solar Energy Industries Association (SEIA) at 202-628-7745 for a list of solar service providers.
• Contact PG&E to see which installers they recommend.
• Contact your local building inspector to see which installers they recommend.
• Confirm contractor licenses with the California Electrical Board.
• Ask prospective installers about their experience, including years in business or number of systems installed.

System Installation &
Grid Intertie

PV systems are installed prior to connection to the utility grid. In California, connecting to the electric grid allows a system owner to reap the benefits of “net-metering”. Before the system can be connected to the grid, the system owner must have the building department inspect the system. The system owner must also complete an “Interconnection Agreement” with PG&E, and have a PG&E technician present at the time of connection. For more information about Interconnection Agreements or to apply, visit PG&E's website. Questions can be emailed to PGE at gen [at] pge [dot] com or left as a message at the net-metering hotline: 415-972-5676.

Grid-tied photovoltaic (PV) systems should be interconnected by a licensed electrician in compliance with the National Electrical Code (NEC) using equipment listed with the Underwriters Laboratories (UL). The Institute of Electrical and Electronic Engineers (IEEE) has developed standards for safe interconnection of PV systems with the local electric utility. For more information on grid-tied photovoltaic systems, see page 4 of this guide or consult your solar energy contractor.

Applying for a Building Permit

Before installing a solar energy system, you or your qualified solar service provider must investigate local building codes, zoning ordinances, and community association covenants pertaining to the site. You must comply with existing building codes and permit requirements when you design and install your system. Understanding the requirements during the design phase of your project will minimize complications. Outstanding permitting issues must be resolved before new permits will be issued for solar electric systems. Building code compliance for a solar system installation is a local issue. If you are within city limits, go to the City building department. If you are outside a city, go to the County Building Department.
