Flat and low-slope
Industrial and multi-tenant commercial
Large roof planes and steady daytime load make these the strongest candidates for hosted storage and energy sales alongside a roof replacement.
For commercial, industrial and multifamily owners and developers
Onsite energy for commercial and multifamily buildings.
Quad Services designs and bids the solar and storage for your building, as your owner's rep, with financing options that can keep it off your capital budget. Where a property has available power and space, we can also help identify distributed computing opportunities.
California first. Title 24 already requires solar and storage on new high-rise multifamily and most nonresidential buildings. We turn that cost line into a revenue line.
Who this is for
Buildings with roof area, steady load, or a code requirement to meet.
New construction and existing portfolios both qualify. The strongest sites have large roof planes and steady daytime load.
4+ stories
High-rise multifamily
Solar and storage are required by code. Resident energy value plus site lease income or revenue sharing for the owner, with tenant billing handled.
Office, retail, hotel, school
Nonresidential
Where roof area meets the threshold, the code asks for solar and storage. Firm power for new loads such as EV, HVAC and compute, and revenue from the surplus.
Several sites
Existing portfolios
Share bills, meter data or just a list of addresses. We rank every site by what it can save and earn, then bid the top ones.
Why now
Title 24 makes onsite energy mandatory. It does not say who designs it, funds it or bills it.
Since 2023 new high-rise multifamily and most nonresidential buildings in California need solar and storage. The 2025 code, in force since January 1, 2026, tightened both. Builders treat it as a cost line. Each part of that cost line is a service we provide.
| Building type | What Title 24 requires | Since | Who decides | What they need |
|---|---|---|---|---|
| High-rise multifamily4+ stories | Solar PV and battery storage, sized by code equations, capped by usable roof area | 2023updated 2026 | Developers, owner's reps, GCs, capital partners | Capital that takes it off the budget, and a way to bill tenants |
| Nonresidentialoffice, retail, warehouse, school, grocery, hotel | Solar PV and storage where roof area meets the threshold; community solar or storage can satisfy part of it | 2023updated 2026 | C&I developers, owners, tenants with energy spend | Firm power for new loads and revenue from surplus |
| Low-rise multifamily1–3 stories | Solar PV sized to floor area and climate zone; storage can offset part of the PV | 2020updated 2026 | Production builders and their trades | A design that bids cleanly and a roof that does two jobs |
| Existing buildingsre-roof or retrofit | No mandate. A new roof is the one moment solar is cheapest to add, and rising rates make storage pay | ongoing | Owners, asset managers, property managers | A site lease and a rate below the utility, with no capex |

The economics
One system on your property can earn four ways at once.
Energy made and stored on site is worth more than energy from the grid, because every stream lands in your NOI.
-
Tenants
Residents and commercial tenants opt into a solar subscription on one combined utility and solar bill, at a lower rate than the utility.
Pays: subscription payments -
Common areas
Elevators, lighting, pools, HVAC and parking run at the onsite rate instead of the retail rate.
Pays: lower operating costs -
Grid and virtual power plant
Many batteries act as one power plant at peak times. Utility and grid programs pay batteries to discharge when power costs the most.
Pays: utility and grid payments -
Distributed computing
Some properties have power and space to spare. Where a site qualifies, Quad Services can help identify a distributed computing opportunity. Each site is evaluated individually.
Pays: site lease, where it qualifies
On your property
What actually goes where.
Solar on the roof or over parking. Batteries in sealed, fire-protected enclosures in unused space. The rest is switchgear, meters and wiring. Every project gets a site-specific plan.
Solar
Bolt-on panels, carports, or a Quad+ solar roof where the roofing itself is the array. Sized to the site and designed as two comparable sets so you can see the options side by side.
Energy storage
Central container, cabinet or portable units. Every cell monitored, fire suppression built in, insured and financeable. Only storage that can be insured is installed.
Switchgear and meters
Sub-metering and energy management that split the bill by source and by hour, so each building meter is billed exactly for what it used.
Grid interconnection
Interconnection coordinated with your utility. Batteries can sell back to the grid under utility programs.
How a project starts
Two tracks, one free review. Quad Services runs both.
New buildings already need solar, so we join at the design stage. For existing buildings and portfolios, we start with your data and rank where the money is.
Track 1 · New construction
Join at design
Quad Services reviews the plans with your architect and MEP, using the roof material you already spec'd.
Compare options
Quad+ solar roof vs regular solar, plus storage, as two permit-ready design sets.
Bid and fund
Three contractor bids on identical scope. Pay cash, or use financing through our finance partners.
Build on schedule
Installed as part of the construction timeline, never on your critical path.
Operate
Lower energy costs from move-in day, with reporting for the life of the system.
Track 2 · Existing buildings and portfolios
Share your data
Bills, meter data, or just a list of addresses.
Screen the portfolio
Every site ranked by what it can save and earn.
Compare and bid
Cash or financing, and three bids for each top site.
Build
New solar roof, racked PV, storage, or add-ons to existing solar.
Operate
Savings and income tracked site by site for 20+ years.
Questions owners ask
The short answers.
Why is the review free? What does Quad Services get?
The evaluation and the model cost you nothing. Quad Services is paid for design, bidding and owner's-rep services, and there is no fee until you choose a build pathway.
Is it safe to put batteries next to an occupied building?
Only storage that can be insured and financed is installed. Every cell is monitored, fire suppression is built in, and the units carry the certifications utilities, fire marshals and insurers require. Every battery system is insured.
Does this work for tenants on separate meters?
Yes. Tenants opt into a solar subscription on one combined utility and solar bill at a lower rate. Common areas run at the onsite rate too, which lowers your operating costs.
Next step
Find out what your property could earn.
An address is enough. Bills, meter data or plans make the model sharper. We come back with a site-specific model, the two design options and the financing options.
