The Inland Empire — Riverside and San Bernardino counties — is California's fastest-growing region and one of its strongest solar markets. SCE serves most of the region; some areas have IID (Imperial Irrigation District) or smaller municipal utilities. The IE gets more sun than coastal CA — 6.0+ peak sun hours in many areas — and SCE rates make NEM 3.0 solar + battery economics solid. Growing families and new construction throughout Murrieta, Temecula, and Rancho Cucamonga represent significant solar demand.
