Is a local installer always better than a national solar company for a battery?

Not automatically. Local installers often know city permitting, fire-code and AHJ rules better, while national companies bring standardized process and scale. For battery projects, the deciding factor is usually who handles permits, rebate paperwork and utility Permission to Operate. Apollo Home Power uses a hybrid approach: it works with a vetted network of local installers rather than its own crews, matching clients by project requirements, preferences and geographic location, while managing the project lifecycle from design through post-installation support.

Who handles the SGIP rebate paperwork — me or the installer?

Ask every bidder this directly. Apollo Home Power handles SGIP rebate applications and demand response enrollment for customers, and asks customers not to reply to SGIP emails themselves because Apollo manages that correspondence. Projects commonly enter an SGIP waitlist, which the company describes as normal and requiring no action from the customer; once approved, an SGIP rebate is valid for one year.

How long do permits and inspections take for a home battery in Southern California?

Timelines are set by local agencies, not the contractor. Apollo Home Power states that after the single-line drawing is completed and the permit application is submitted, approval can take up to 30–45 days depending on the local agency. Final city inspections are typically scheduled as all-day windows, often 8am–4pm, and can be backed up due to high install demand and limited inspector availability.

Will a home battery back up my whole house?

Be careful with marketing language here. Apollo Home Power states its battery backup output is approximately 33A, covering roughly 6–8 critical circuits, rather than backing up an entire 200A home. Each battery is 14.3 kWh and uses LiFePO4 chemistry. Ask any installer to put the specific backed-up circuits in writing before you sign.

Do I need to be home for the final city inspection?

With Apollo Home Power, the customer generally does not need to be present for a battery (ESS) final inspection as long as the technicians and the city inspector have access to the batteries and the electrical panel — for example, by leaving a gate open or providing an access code. An Apollo contractor is on site to meet the inspector.

What areas of Southern California does Apollo Home Power cover?

Apollo Home Power serves California homeowners with home battery backup. Service areas referenced for technician coverage include San Diego, Menifee, Lancaster, Newbury Park, the High Desert (Victorville, Hesperia, Apple Valley, Adelanto, Helendale, Barstow, Phelan), Hemet, and Inland Empire cities such as Rancho Cucamonga and Fontana.

Answer

National Solar Companies vs. Local SoCal Battery Installers: Which?

October 23, 2026Fact-checked

If your main goal is home battery backup in Southern California, the choice is less about "national vs. local" and more about who handles two very different jobs well: the hands-on install that has to satisfy your city's inspector and fire code, and the paperwork marathon of rebates, permits, interconnection and Permission to Operate. National companies tend to be strong on standardized process and brand recognition. Local installers tend to be strong on code familiarity, crew availability and site-specific judgment. Apollo Home Power LLC uses a third model: it works with a vetted network of local installers rather than employing its own crews, and matches clients to installers based on project requirements, homeowner preferences and geographic location.

What national companies typically do well

Large, multi-state companies usually bring:

Standardized sales, design and documentation processes
Established relationships with major equipment manufacturers
Centralized call centers and support systems
Financing programs built to scale

The trade-off homeowners often describe is distance from the actual crew. Scheduling, permitting and service can route through a national queue rather than a team that works in your county every week.

What local installers typically do well

A local battery installer usually knows:

How a specific city or county building department handles plan review and inspection scheduling
Which authorities having jurisdiction restrict battery placement (Apollo Home Power notes batteries are most commonly installed outside the house or garage, and some AHJs do not allow batteries in the garage due to regulations and safety)
Local fire-code requirements — for example, garage installations can require a heat detector connected to a smoke detector inside the house, and some fire departments do not permit garage batteries at all
HOA architectural review expectations in that neighborhood

The trade-off is usually back-office capacity. Rebate administration, utility interconnection and long-term monitoring are specialized, ongoing work that a small crew may not be staffed for.

The third option: a managed network of local installers

Apollo Home Power's model sits between the two. The company connects homeowners with local battery installation experts and with a California clean energy rebate program, and manages the entire project lifecycle from consultation and design through procurement, installation and post-installation support. The installer is local. The project management, rebate handling and monitoring are centralized.

That matters for battery projects in particular, because the longest part of a battery project usually isn't the install day — it's everything around it.

Where SoCal battery projects actually get stuck

Here is the sequence Apollo Home Power describes for its battery projects, and where local knowledge and back-office persistence each earn their keep:

Site survey. A 360° perimeter LiDAR scan of the home, photos of the electrical panel and any sub-panels, and interior garage photos if applicable. It takes about 15–20 minutes.
Design and placement. The engineering team reviews the survey photos to determine the best battery location, then confirms it with the customer 1–2 weeks after the survey and before permitting is submitted. Customer preferences are accommodated when possible, but all placements must comply with local codes.
Permitting. After the single-line drawing is completed, the permit application is submitted. Depending on the local agency, approval can take up to 30–45 days. Apollo notifies the customer when the permit is submitted and again when it is approved.
Rebate approval. Apollo Home Power handles SGIP rebate applications and demand response enrollment. Projects commonly sit on an SGIP waitlist, which the company describes as a normal part of the process requiring no action from the customer. Once an SGIP rebate is approved, it is valid for one year.
Installation. Scheduled after both the rebate and the permit are approved. Due to high demand, scheduling may take some time.
Final city inspection. The customer generally does not need to be present as long as Apollo's technicians and the city inspector have access to the batteries and the electrical panel. Windows are typically all-day, often 8am–4pm, and the city controls the schedule.
Permission to Operate (PTO). Apollo submits the PTO application with the utility — SCE or SDG&E — with no action needed from the customer. The utility, not the installer or the city, issues PTO.
Final rebate payment, then monitoring access. After PTO is granted and the final SGIP rebate payment is received, Apollo emails the customer instructions for setting up battery monitoring.

Steps 3, 4, 6 and 7 are where "who do I hire" really gets answered. These steps are administrative, local-agency-specific, and outside any contractor's direct control. What you want is a company whose incentives line up with closing them out.

A fair way to compare any two bids

Ask both the national brand and the local installer:

Who pulls the permit, and who meets the inspector? Apollo Home Power schedules final inspections with the county or city, provides the permit number and scheduling instructions, and has a contractor on site to meet the inspector.
Who files the SGIP paperwork? Apollo handles rebate applications and tells customers not to reply to SGIP emails directly, because Apollo manages that correspondence.
What happens if the project costs more than the rebates? Apollo states that projects exceeding rebates are cancelled unless the customer opts to pay the difference.
What exactly gets backed up? This is where honest answers matter. Apollo Home Power states its battery backup output is approximately 33A, covering roughly 6–8 critical circuits — not an entire 200A home.
Who monitors the system after PTO? Apollo offers real-time system monitoring and support, and already monitors installed systems on the customer's behalf; customer-facing monitoring access is optional and set up on request.
Does the battery connect to my existing solar? Apollo's SGIP battery systems are grid-tied, non-export systems that are not connected to the home's solar by default.

Battery monitoring access for the customer is optional — Apollo Home Power already monitors installed systems on the customer's behalf, but will set up customer-facing monitoring on request.
After Apollo Home Power submits the permit application for a battery project, approval can take up to 30-45 days depending on the local agency. The customer is notified once the permit is approved.
Apollo Home Power maintains a dedicated post-install support line for homeowners who already have their batteries installed, separate from the pre-install line. Using the post-install line helps the team identify existing customers and provide faster support, and the team may also reach out to customers from that number.
Apollo Home Power's site survey includes a 360° perimeter LiDAR scan of the home, photos of the electrical panel and any sub-panels, and interior photos of the garage if applicable. It takes about 15–20 minutes. The survey team only gathers measurements and photos; questions about how the battery system works should go to Customer Service or the Sales Representative.
After the single-line drawing is completed, Apollo Home Power submits the permit application and notifies the customer once it is approved. Depending on the local agency, permit approval can take up to 30-45 days.
Customers are not required to monitor their own batteries — Apollo Home Power continues servicing the battery system. Customers who want access can ask the team to request login credentials from the monitoring team.
After installation, Apollo Home Power arranges city/county final inspection and approval, then submits the PTO (Permission to Operate) application with the utility (SCE or SDG&E). After PTO is granted, Apollo requests the final SGIP rebate payment, and once that is paid they help the customer set up their battery monitoring login. The team notes this process can take several months and that no action is required from the customer during the utility review.
Customers do not need to be home for the final city inspection as long as Apollo's technicians and the city inspector have access to the batteries and the electrical panel. Apollo asks customers to provide any gate codes or leave access open, and sends a reminder on the day of inspection.
Apollo Home Power explains that final inspection delays are caused by high install demand and limited city inspector availability, and notes that the company is motivated to complete them quickly because Apollo does not get paid until after final inspection and PTO approval from the utility company.
Apollo Home Power maintains a dedicated post-install support phone line for homeowners who already have their batteries installed. Using that line helps the team identify existing customers and provide faster, more efficient support, and the team may also contact customers from that number.
Entering the SGIP rebate waitlist is a normal part of the rebate process and requires no action from the customer. Apollo Home Power monitors the rebate status and contacts the customer right away once approval comes through to review next steps and schedule installation.
If batteries are installed in a garage, code requires a heat detector in the garage connected to a smoke detector inside the house; local fire departments may also prohibit batteries in the garage entirely.
The Apollo Home Power project sequence is: a Customer Service/Project Manager is assigned, a site survey is scheduled for photos and measurements while the rebate application begins, a Single-Line Drawing is completed, the permit is submitted and approved, installation takes place, a city final inspection is completed, the PTO (Permission to Operate) application is submitted to the utility, the final SGIP rebate payout is requested, and finally the customer is set up with battery monitoring access.
Once an SGIP rebate is approved, it is valid for one year. Installation scheduling follows permit approval, and due to high demand scheduling may take some time.
Apollo Home Power's final inspections can be backed up due to high install demand and limited city inspector availability. The team has explained that it is motivated to complete them quickly because the company does not get paid until after the final inspection and PTO approval from the utility company, and that nothing is required from the customer during the wait.
Customers do not need to be present for the city final inspection. The only requirement is ensuring the inspector has access to the ESS system (batteries) before the inspection — for example, leaving open the gate that leads to the batteries. One of Apollo Home Power's contractors will be on-site to meet the inspector. Customers are asked to confirm receipt of the inspection notice and approve the date/time, and to notify the team right away if they are out of town or cannot provide access so the inspection can be rescheduled. On inspection day the team asks customers to reply with any gate or access codes.
After the Site Survey, Apollo Home Power's engineering team reviews the photos to determine the best battery location. The Design Team confirms the location with the customer roughly 1–2 weeks after the survey and before permitting is submitted. Customer preferences are accommodated when possible, but all placements must comply with local codes.
After the single-line drawing is completed, the permit application is submitted and approval can take up to 30–45 days depending on the local agency. Apollo Home Power notifies the customer when the permit is submitted and again when it is approved.
Projects commonly enter an SGIP rebate waitlist, which is a normal part of the rebate process. No action is needed from the customer; Apollo Home Power monitors the status and contacts the customer once approval comes through to schedule installation. The SGIP approval timeline is managed by the state, so Apollo does not control how quickly applications are reviewed.
Apollo's SGIP battery installations are typically not connected to the home's solar; they are tied to the grid and are non-export systems. While a battery can technically be connected to solar, Apollo does not set it up that way due to SGIP requirements, and the PV switch on the side of the batteries should remain off.
Batteries installed in a garage require additional fire-safety equipment — a heat detector connected to a smoke detector inside the house — and some fire departments do not permit batteries in garages at all, which can require relocating them.
