How to Add Solar Panels to Your Los Angeles Home Renovation

Southern California homeowners are asking one question more than ever during remodeling: should I add solar panels while I renovate? The answer is usually yes, and the reason is simple. When your roof, electrical panel, or living space is already open for construction, adding solar costs less, goes in faster, and looks better than a retrofit done years later. LevelWorks Construct & Renovate has guided homeowners across Los Angeles and Orange County through full remodels and new construction for more than a decade, and the projects that turn out best treat solar as part of the plan from day one, not an afterthought.

Why plan solar into a renovation instead of adding it later

Every renovation touches systems that solar also touches. A kitchen remodel rewires the home. A roof replacement re-decks the surface where panels will sit. A room addition adds square footage and, usually, a new subpanel. When those projects happen separately, you pay twice for labor, permits, and coordination. When they happen together, one construction team, one permit process, and one timeline deliver both.

There are three specific reasons to plan solar at the renovation stage:

• Roof access.

  If your remodel includes roofing work or a new second story, the crew is already on your roof. Mounting systems, flashing, and panel placement can be coordinated while the decking is exposed.

• Electrical efficiency.

  A panel upgrade that supports solar is often required anyway when a remodel adds circuits. Doing it once, sized for solar, avoids a second expensive visit from an electrician.

• Design freedom.

  Solar equipment can be placed where it performs best instead of where it fits around an existing roof layout. A design-build contractor can position panels, conduit, and the inverter so the finished home looks intentional.

Homeowners who retrofit solar a few years after a remodel consistently tell us they wish they had done it during the project. The savings in time and disruption are real, and the return on investment starts sooner.

What does a solar-ready renovation involve?

A solar-ready renovation is not a different kind of remodel. It is a remodel that keeps a few future-proofing decisions in mind. Your general contractor, electrician, and solar installer should discuss these four items before construction begins:

Your electrical panel and meter

Most older Los Angeles homes have 100-amp panels, and most solar installations require 200 amps of capacity. If your renovation is already adding circuits for a new kitchen, bathroom, or ADU, sizing the panel for solar at the same time is a small incremental cost. It also makes the utility interconnection paperwork simpler later.

Roof condition and orientation

Solar panels are rated to last 25 years or more. If your roof will need a replacement in that window, install panels on a roof that is already sound. A renovation that includes re-roofing is the perfect moment to plan panel layout with the roofer. South-facing slopes in Southern California produce the strongest output, but east and west exposures also work well with modern systems. Shading from mature trees, chimneys, and neighboring buildings should be mapped before you commit to a layout.

Conduit and inverter placement

The inverter, and often a battery in newer systems, needs a clean, accessible spot that is not in the middle of your living space. During a remodel you can route conduit through walls that are already open, which keeps the exterior of the home clean and makes the inspection process smoother.

Energy-use planning

Sizing a solar system starts with your current electricity use, then adds your planned changes. A home addition with electric appliances, a heat pump, or a new ADU will use more power than your old home did. Share your renovation plans with the solar designer so the system is sized for the home you are building, not the home you are leaving.

Can I add solar panels during a kitchen remodel or room addition?

Yes, and these are two of the most common projects we pair with solar. A kitchen remodel in Los Angeles typically triggers an electrical permit because you are adding dedicated circuits for appliances, lighting, and ventilation. That is the same moment your electrician can upgrade the panel to solar-ready capacity and run the conduit path.

For a room addition or new construction project, the case is even stronger. A new structure has a new roof, and California building codes require modern energy performance. Putting solar on a new roof is cheaper per panel than any retrofit, because scaffolding, flashing, and permits are already part of the build. Many of our addition clients in Pasadena, Irvine, and Long Beach fold solar and battery storage into the same construction loan.

What are the permit and utility steps in Los Angeles?

Solar installation in Los Angeles follows the same general path as other home construction, with a few utility-specific steps. The process in 2026 is faster than it was a decade ago, but it still requires planning:

• Building permit.

  Your city or county reviews the structural and electrical plans. Licensed contractor and electrician credentials are verified at this step.

• Utility interconnection.

  LADWP and Southern California Edison both require an application to connect your system to the grid. The California Public Utilities Commission oversees the interconnection rules and

  customer generation programs

  that govern net metering for homes across the state.

• Final inspection.

  A building inspector verifies the installation against the approved plans before your utility gives the final go-ahead.

Your general contractor should coordinate these steps with the solar company so the electrical work passes inspection the first time. When one team manages the timeline, the solar permit rides alongside the remodel permit instead of becoming a separate delay.

How much should a solar-ready remodel cost?

Solar pricing is quote-based and depends on your system size, roof complexity, panel choice, and whether you add battery storage. What we can tell you from hundreds of projects is that the marginal cost of going solar during a renovation is meaningfully lower than the all-in cost of a later retrofit, because labor and permits are shared. The additional costs you should plan for inside the remodel itself are the panel capacity upgrade and the conduit route, both modest line items when walls are open.

Federal and California incentives can reduce the net cost of the solar portion. Incentive amounts change, so verify current program details with your solar installer or a tax professional rather than relying on an article. What does not change is the principle: a system installed during construction is cheaper, cleaner, and easier to maintain than one added later.

Choosing a qualified solar installer for your renovation

Your renovation contractor and your solar installer are separate specialists, but they need to work like one team. Look for an installer that:

• Holds a current California contractor license and verifies insurance

• Has experience with roof-integrated systems, not just ground mounts

• Will coordinate engineering drawings with your general contractor before permits are filed

• Discloses panel, inverter, and warranty details in writing

For Los Angeles homeowners planning a full renovation, a licensed solar installer such as AMECO Solar can design a system sized to your roof, your energy use, and the home you are building. Ask your contractor and the installer to sit in the same design meeting. That single conversation resolves the panel placement, the conduit path, and the electrical upgrade before anyone pours concrete or frames a wall.

Working solar into your construction timeline

Solar adds roughly two to four weeks of coordination to a typical remodel, but almost none of it is critical-path time if it is planned. The solar milestone that matters is roof and electrical readiness: the install itself usually takes a few days once the roof decking and panel capacity are in place. Your project manager should sequence it so the solar crew arrives after roofing and before drywall on the interior conduit route.

This is where a dedicated project manager earns their keep. LevelWorks assigns a project manager across our Los Angeles and Orange County service areas to every remodel, and one of their jobs is scheduling subcontractors, including specialty trades like solar, so the build flows without idle weeks. Clear communication between the general contractor, the solar company, and the homeowner keeps the timeline honest from the first estimate through the final walkthrough.

Should solar change your renovation design?

In most cases, no. Solar panels are flat on the roof, and modern systems sit close to the roof plane. If you are designing a backyard renovation with an outdoor kitchen, pergola, or detached structure, you have an extra option: a small independent solar array can offset the new outdoor circuits, and battery backup can keep the entertaining space running during an outage. For deeper design questions about solar-ready building science, resources like Green Building Advisor and the U.S. Department of Energy solar hub are reliable references.

The design decision that matters is placement, not style. Panels should face the sun, not the street. A design-build team will show you renderings of the finished roof so there are no surprises after installation.

Start the conversation early

The single best piece of advice we give every homeowner is to bring up solar in the first consultation, not the last. An early conversation shapes the electrical plan, the roof work, the permit strategy, and the timeline, and it costs nothing extra to ask. By the time you are picking finishes, the solar decision should already be made and approved.
