Solar Savings Without a Balcony: California SOMAH for Affordable-Housing Renters

For a California renter, rooftop solar can seem out of reach. The roof belongs to someone else, the building may have no balcony, and buying equipment is not the right answer for every household. California’s Solar on Multifamily Affordable Housing program, known as SOMAH, offers a different route at qualifying affordable rental properties: an owner can install on-site solar and allocate the resulting utility-bill benefits to tenant and common-area accounts.

That distinction matters. SOMAH is not a personal solar purchase, and it is not a program a tenant signs up for alone. It is a building-level affordable-housing program. If a property participates, a tenant can receive solar-related credits on the electricity bill without owning panels, operating the system, or having a place to put one. The California Public Utilities Commission, or CPUC, highlighted the opportunity in an October 26, 2026 update: tenants at participating properties saved an average of $58 per month in 2025, about 75% of their average monthly bill. [1]

That historical average is encouraging, but it is not a promise. A simple annualized illustration is $58 × 12 = $696. A particular tenant’s credits and bill outcome can be higher, lower, or unavailable, depending on the property’s participation, the solar allocation, electricity use, utility billing, and other circumstances. The useful next move is not to shop for a kit; it is to find out whether the building may qualify.

What SOMAH is—and what it is not

SOMAH supports solar at eligible multifamily affordable-housing properties. The solar system is located at the property. Under the program’s virtual net energy metering tariff, the owner can assign the benefits from that renewable generator among tenant accounts and the building’s common-area account. A tenant does not need a dedicated set of panels. Credits show on participating customer bills as energy offsets, with utility export-credit treatment when there are net exports in a billing period. [2]

Think of an apartment building with solar on its roof. The building can use part of the program’s solar benefit for shared spaces such as hallways or laundry rooms, while participating tenant accounts receive their assigned share on their utility bills. It is an on-site, building-level arrangement—not an individual system attached to one renter’s window or balcony. SOMAH does not turn a tenant into the system owner, and it does not make an individual tenant responsible for operations or maintenance. [1]

It is also different from off-site community solar. A community-solar subscription generally concerns a separate solar project and a customer enrollment or contract. SOMAH, by contrast, is tied to eligible affordable rental housing and its on-site solar system. It is different again from personal plug-in solar, where a resident considers their own equipment, living space, property permission, and applicable electrical rules. Those are separate decisions and should not be treated as substitutes.

Most important for tenants, the CPUC says a rent increase cannot be attributed to installation of a solar system funded by SOMAH. [1] That protection does not answer every housing or billing question, but it is a meaningful reason to ask whether an eligible property has explored the program.

The first eligibility screen: is this the right type of building?

SOMAH is purpose-built for a defined set of properties, not every apartment community in California. At minimum, the CPUC says a property must be existing, deed-restricted low-income residential rental housing; have at least five rental units; and have all units individually metered. It must also be a utility or community-choice-aggregator customer in the Pacific Gas & Electric, Southern California Edison, San Diego Gas & Electric, Liberty Utilities, or PacifiCorp territories. [2]

The property must also satisfy at least one additional affordability or community condition. The listed paths are: 66% of residents have incomes at or below 80% of area median income; the property is in a defined disadvantaged community; the property is owned by a California Native Tribe; or the property is owned by a Public Housing Authority or Public Housing Agency. [2]

These are program requirements, not a quick online guess. A renter might live in a large, low-cost building that is not deed-restricted, or in a deed-restricted property where units are not individually metered. Either fact can change the answer. Likewise, a building with five or more apartments outside the listed territories should not be assumed eligible. The owner or housing provider should confirm the property’s actual status with the program.

Here is a practical contrast. Imagine a resident at a 40-unit deed-restricted affordable complex whose apartment has its own utility meter. If the property is in a listed territory and meets an additional program condition, its owner may have a path to explore SOMAH. The resident does not apply for an individual rooftop array; they can ask whether the owner has assessed the building.

Now imagine a resident of a market-rate building that has no deed restriction. Even if it has plenty of roof space and individual meters, it does not meet the CPUC’s minimum deed-restricted affordable-housing condition. SOMAH is not the right route on that fact alone. The limitation is specific, but it helps readers avoid waiting for an option that does not fit their building.

Five questions a renter can take to the property manager

A renter does not need to diagnose program eligibility. A short, specific question can open a productive conversation with the property manager, affordable-housing provider, or ownership office:

Keep a copy of any answer that identifies a program, timeline, or billing arrangement. If the building already participates, ask where the solar credit appears on the utility statement and who can explain a missing or unexpected credit. If the answer is that the building has not been evaluated, asking for an eligibility review is more useful than asking the landlord to approve a personal panel by default.

A tenant who has a separate interest in a personal setup can still research it on its own terms. PlugInSolarUS’s California renter and condo preparation guide and renter solar rights guide are starting points for that distinct decision. They do not determine SOMAH eligibility.

What owners and housing providers should confirm

The property owner applies for SOMAH incentives; a resident cannot file an individual tenant application. [1] For an owner, the most efficient first pass is to confirm the core facts before treating solar proposals as comparable: existing deed-restricted affordable rental status, five or more rental units, individual unit meters, service territory, and at least one qualifying income, community, tribal-ownership, or public-housing pathway. [2]

If the deed restriction or regulatory agreement is uncertain, the SOMAH administrator offers an Affordability Prescreen Request. The prescreen accepts a copy of the restriction or agreement and provides a notice of eligibility or ineligibility; the site says no formal application is required for that service. [3] This is a useful fact-finding step, not an approval or a guarantee of incentives.

For a property that appears to fit, the official SOMAH application page routes owners to utility-specific PowerClerk portals. The application page lists Liberty Utilities, Pacific Power, PG&E, San Diego Gas & Electric, and Southern California Edison. [3] Program staff can then address the project-specific requirements, documentation, allocation, and timing that a generic solar quote cannot answer.

Owners should not present credits as a fixed tenant benefit before the project and billing arrangement are established. They should explain the program in plain language, distinguish tenant accounts from common-area accounts, and give residents a clear contact for bill questions. That is good housing communication as well as good program practice.

A solar option that begins with the building, not a product

SOMAH is a positive example of solar benefits reaching residents who do not control a roof or balcony. But its value is in the fit: a qualifying affordable rental property, owner participation, and an on-site system whose benefits can be allocated to tenants. It is not a universal California renter benefit, an automatic $58 monthly credit, off-site community solar, personal photovoltaic equipment, or backup power.

For an eligible renter, the best next step is simple: ask whether the property is SOMAH-eligible or already participating. For an eligible owner, begin with the program screen and official application channel. If a household later explores a completely separate personal plug-in solar option, use the PlugInSolarUS Product Finder to compare current offers—including Rowkin options—only after the space, property, and applicable rules have been assessed. No equipment purchase is needed to pursue SOMAH.
