How Integrating Rooftop Solar Early Helps Grocery Store Developers Address Title 24 and Maximize Profits

California’s new solar requirements add complexity to grocery store development. But with the right planning, compliance can become an opportunity to control construction costs, lower long-term energy expenses, and improve your store’s financial performance.

Building a new grocery store means making hundreds of interconnected decisions, each affecting construction costs, project timelines, and years of operating expenses. California’s updated Title 24 building energy standards just added another layer of complexity. New Building Energy Efficiency Standards took effect January 1, 2026. What does that mean? Qualifying newly constructed nonresidential buildings, including covered grocery stores, now have solar photovoltaic (PV) requirements. Many stores will require battery storage as well depending on the specific project.

The challenge is to determine what is actually required for your site and to design a system that works alongside refrigeration and HVAC equipment. You want to coordinate installation with construction and make sure the investment makes long-term economic sense. If you get these decisions wrong or make them too late, you risk expensive redesigns, construction delays, and missed savings opportunities.

But you have the opportunity to get solar right from the start and turn these regulatory requirements into a long-term business advantage. A well-planned system can help offset electricity costs, support more efficient building operations, and create measurable financial and sustainability benefits across your store portfolio.

Here’s what you need to be considering for every new grocery store you’re planning to build:

1. Determine your Title 24 requirements before design decisions are locked in

For projects with permit applications submitted on or after January 1, 2026, the development team should determine the applicable requirements during the early planning stages. The building’s roof configuration, structural design, electrical systems, equipment placement, and available solar access can influence how the project is designed and delivered.

An early assessment can help the developer, architect, engineer, and energy-code consultant establish a workable approach before drawings and construction budgets are finalized.

The code’s battery-storage provisions means you may need that as well, though specified exceptions and compliance alternatives can apply. Is your project team able to confirm the requirements for its specific design?

2. Get the right design for the energy realities of grocery retail

Grocery stores have a distinctive energy profile. Refrigeration and cooling equipment are central to daily operations, while lighting, HVAC, checkout systems, and food preparation add further demand.

A rooftop solar system can generate electricity during daylight hours and offset some of the electricity the store would otherwise purchase. Its financial value depends on the building’s load profile, utility tariff, system capacity, local solar conditions, and applicable compensation rules.

The opportunity begins with the building design.

The development team should consider the placement of rooftop HVAC equipment, refrigeration systems, vents, access routes, and other obstructions alongside the proposed solar layout. Structural loading, roof warranties, waterproofing, fire-access requirements, and electrical routing should also be coordinated.

For a new store, integrating these considerations during design can help avoid the cost and disruption of trying to accommodate solar after the roof and mechanical systems are already finalized.

You need a design for a building that allows the roof, mechanical equipment, and solar installation to all work together.

3. Make the roof part of the development strategy

Not every square foot of a grocery store roof will be available for solar. Equipment, shading, access requirements, and structural limitations can restrict the usable area.

California’s prescriptive sizing approach considers both solar access roof area and a code-defined capacity calculation. The required system is generally based on the smaller of those calculations, while performance-based compliance may provide another route.

That makes early coordination especially valuable.

A developer needs to know the proposed roof’s usable solar area, the expected PV capacity, and the potential interaction with HVAC and refrigeration equipment before finalizing the design.

If the roof cannot accommodate a practical configuration, other eligible approaches may be possible. Depending on the property and compliance pathway, these can include ground-mounted solar or solar carports.

For grocery retailers with substantial parking areas, a solar canopy may offer a complementary opportunity. It can generate electricity while providing shade or weather protection over selected parking spaces, pickup areas, or customer entrances.

The most appropriate configuration depends on site conditions and the applicable code requirements.

4. Evaluate the economics before committing capital

You need to feel confident that the proposed building meets the applicable code, but is also a sound, long-term financial decision.

A useful financial assessment should evaluate installation costs, projected energy production, electricity tariffs, financing, maintenance, roof-related costs, and the expected operating life of the system.

Grocery chains should also consider the interaction between solar production and their energy consumption. A system that generates electricity when the store is using substantial power may deliver a different financial result from a system whose output frequently exceeds the building’s demand.

Battery storage can shift some generated electricity for later use, depending on system configuration and operating strategy. Where storage is required by code, its sizing and design should be incorporated into the project budget from the outset. Where it is not required, its additional financial value should be evaluated separately.

Applicable incentives and tax benefits may influence your investment case, but eligibility depends on current law, project structure, and other requirements. You want this to be verified to understand the full investment opportunity.

5. Coordinate solar with construction, not after construction

Because your new store involves a complex sequence of design, permitting, procurement, site work, structural construction, roofing, mechanical installation, electrical work, and final inspections, you want to consider solar early in the process. That means clarifying who is responsible for the PV design, structural review, electrical integration, permitting, utility interconnection, battery-storage design where applicable, and commissioning.

It also means identifying potential conflicts before construction: roof penetrations, equipment clearances, conduit routing, electrical-room capacity, construction access, and the sequencing of installation work.

Integrate Solar can help bring the solar-development process together through site assessment, design coordination, permitting support, and evaluation of financing options and all available incentives.

6. Build a repeatable process for every new location

If you’re a grocery chain with multiple locations set to be built, you should not have to reinvent your approach to solar for each new store.

Instead, your company can establish standard development checkpoints covering site selection, preliminary solar feasibility, roof and electrical coordination, code review, financial analysis, and construction planning.

At the site-selection stage, the team can identify obvious constraints and evaluate the building’s energy needs. During schematic design, it can assess roof layout and likely system configuration. During detailed design, it can coordinate the engineering and code-compliance requirements. Before construction, it can finalize the scope, schedule, and commercial arrangements.

This process can help the company identify problems earlier, compare opportunities across locations, and make more consistent capital decisions.

For developers planning stores across multiple California markets, that consistency can be as valuable as the solar installation itself.

7. Treat compliance as a starting point for better building performance

Meeting Title 24 is a regulatory requirement, but the design process creates an opportunity to think more broadly about the building’s long-term performance.

The development team can assess how solar generation aligns with refrigeration and HVAC demand, whether battery storage supports the intended operating strategy, and how the system will be monitored and maintained.

The company can also measure actual electricity generation and grid electricity displaced to support accurate sustainability reporting.

Those benefits should be quantified using site-specific assumptions and, after installation, verified performance data.

Integrate Solar helps you through this process

Adding solar to that mix can create more coordination, more technical decisions, and more opportunities for costly changes if the work isn’t integrated early.

Integrate Solar helps simplify the process by bringing the key pieces of a commercial solar project together, from initial assessment and design through permitting and project planning.

Instead of having your development team piece together the process independently, Integrate Solar can help evaluate the site, identify practical solar configurations, coordinate design considerations, and assess financing options and potentially available incentives.

That support can help your team address critical questions early:

• What does this store need? Evaluate the building and site to understand solar feasibility and the applicable Title 24 requirements.
• Where should the solar go? Assess the available roof area and consider alternative configurations, such as solar canopies, when appropriate.
• How will it fit into construction? Identify the structural, electrical, permitting, and installation considerations that need to be coordinated with the broader development team.
• How should the project be financed? Explore potential financing structures and applicable incentives to understand the financial implications.
• What needs to happen next? Establish a clearer path from preliminary assessment to detailed design, approvals, and installation.
