For a homeowner in the City of San Diego considering solar plus battery storage on SDG&E service, the project discussion should include any required smoke or heat alarms. Ask the installer to explain the alarm design and identify who supplies, installs and pays for that work. A complete scope makes a qualifying solar-plus-battery PPA easier to evaluate before installation begins.
What the city asks to see
The City’s May 2026 Information Bulletin 301 addresses solar and energy-storage permitting. In its residential PV plan-template instructions for single-family, duplex and townhouse projects, it calls for plans to show smoke alarms and/or heat alarms where smoke alarms cannot be installed based on their listing.
That wording is a reason to ask for a project-specific explanation. It does not establish that any alarm bought at a hardware store is suitable, or that every indoor and outdoor battery arrangement uses the same solution. Have the responsible designer identify the applicable requirements and equipment for the proposed location. Confirm the permitting jurisdiction; City of San Diego instructions do not automatically govern every San Diego County address.
Put responsibilities in the proposal
Our suggested homeowner questions are:
- Which alarm equipment, if any, is included in this project’s approved design?
- Who purchases and installs it, and is that work included in the quoted scope?
- Who provides the operating instructions and explains testing and maintenance?
- If the design changes, how will the updated equipment, price and responsibilities be documented?
For a hypothetical example, suppose a proposal describes panels and one battery but says nothing about related alarm work. Ask for an explanation before treating the quoted package as complete. The answer might identify included work or a separately priced item; this example does not establish a required device, additional charge or permit outcome.
Keep the written answer with your proposal and final project documents. Our San Diego inspection-appointment guide covers the later inspection visit.
Keep utility authorization on the checklist
For a home served by SDG&E, local permitting and utility interconnection are separate steps. SDG&E’s installation center provides its interconnection application process. Ask your installer who is tracking the utility’s authorization and what remains outstanding. An alarm installation or a completed city inspection alone should not be treated as permission to operate the system.
Compare the complete PPA and backup design
A suitable PPA can help an eligible homeowner obtain solar equipment without purchasing the system upfront. The CPUC solar guide explains that a PPA involves provider ownership and ongoing payments for solar electricity. Confirm the actual offer’s qualification rules, upfront charges, electricity rate, escalator, term, battery fees, maintenance, transfer terms and remaining utility costs. Ask whether related installation work is included. No upfront purchase does not mean free electricity or guaranteed savings.
Also ask which household circuits the battery will support. PG&E’s general battery guidance explains that backup capability depends on the system and household demand. Ordinary grid-tied solar alone generally does not power a home during an outage. Battery runtime is limited by available stored energy and connected loads; solar recharging during an outage needs compatible backup equipment and suitable sunlight. Alarm-plan compliance does not establish whole-home backup capability.
