This briefing is meant to provide solar photovoltaic system owners, commercial and residential, an overview of the operation and maintenance landscape for aging solar systems in Southern California, directing them toward the services they need. It does not offer a complete survey of such service providers, nor does it comprehensively convey the suite of services available in the solar photovoltaic operation and maintenance (O&M) market. Instead, it provides a high-level description of the types of operation and maintenance services that are generally available to Southern California. This briefing is also paired with a spreadsheet directory of responsive O&M providers that will service solar systems throughout Southern California and occasionally the whole state. Look to it for specific information including service area, company type, and avenues of contact. Click here to read the full briefing.
