Commercial solar installers for businesses, properties, and farms.

Commercial & Multifamily

Commercial solar installers for businesses, properties, and farms.

OC Solar has completed both residential and commercial installations since 2016. Commercial, multifamily, and agricultural projects are unique — so we start with a consultation: we look at your usage, your roof or land, your rate schedule, and your goals before proposing anything.

Commercial, multifamily, and agricultural solar is consult-driven and scoped per project — system size, financing, incentives, and timelines vary widely by site and rate schedule. Figures and incentive availability are confirmed for your specific project during the consultation; nothing here is a quote or a guarantee.

Why homeowners choose OC Solar

Commercial solar installers for businesses, properties, and farms.

Consult-first, never templated

Every commercial site is different. We start by understanding your usage, rate schedule, and roof or land before designing anything.

Solar paired with storage

For many businesses the savings come from cutting demand charges and shifting load — which is why we design storage in from the start.

One licensed contractor

The same CSLB-licensed company (#1023627) that has installed since 2016, with in-house crews — not a brokered hand-off.

Built for property owners

Multifamily, commercial, and agricultural owners get one accountable point of contact from consultation through power-on.

Why commercial solar is its own conversation

Commercial electricity bills are driven by more than usage — demand charges, time-of-use windows, and tariff structure all matter. The right system depends on your specific rate schedule and how your property uses power, so we begin with a consultation rather than a one-size-fits-all proposal.

  • Demand-charge and time-of-use analysis
  • Roof, ground-mount, or carport options reviewed
  • Designed around your actual load profile

Multifamily and agricultural

Multifamily properties and farms have their own considerations — metering arrangements, shared loads, well and irrigation pumps, and seasonal demand. We scope each of these directly with the owner during the consultation so the design fits how the property actually operates.

  • Multifamily metering and shared-load planning
  • Agricultural pumping and seasonal demand
  • Owner-direct scoping and one point of contact
