The Process

Standard solar installation steps

1

Site Assessment

The installer visits your home to inspect your roof, check the electrical panel, and confirm shade measurements.

2

System Design

The design should document equipment, layout, structural and electrical scope, production assumptions, and any battery or service work.

3

Permitting

The contract should assign plan submission and correction work. The Los Angeles Department of Building and Safety (LADBS) handles permitting. Your installer should coordinate this separate from utility interconnection.

4

Utility Application

Confirm who submits the current LADWP / SCE interconnection application and what documents are required before installation.

5

Installation

Panels, racking, inverter, wiring, monitoring, and any approved electrical or battery scope are installed according to the accepted plans.

6

Inspection

Required inspections and corrections should be documented before the project advances to final utility review.

7

Local conditions in Los Angeles

Production depends on roof orientation, shade, equipment, weather, and the address-specific utility; local interconnection rules also vary between LADWP and SCE. Coastal conditions and marine layers can affect an address-specific production model, so proposals should document their weather and shade assumptions. Your installation contract should clearly define who is responsible for necessary roof repairs, tree trimming, or electrical service panel upgrades required to meet local code.

Common installation questions

How long does solar installation take in Los Angeles?
There is no reliable citywide timeline. Design, corrections, equipment, financing, Los Angeles Department of Building and Safety (LADBS) review, inspection, and LADWP / SCE interconnection can each affect the schedule. Ask for current milestone estimates and responsibility for delays in writing.
Who handles solar permits in Los Angeles?
The Los Angeles Department of Building and Safety (LADBS) handles permitting. Your installer should coordinate this separate from utility interconnection. The contract should identify who prepares the plans, submits the permit, responds to corrections, and schedules required inspections.
What utility approval is required from LADWP / SCE?
LADWP / SCE has its own interconnection process. Do not energize or export from the system until the installer confirms all required inspections and utility approvals are complete under the current rules.
Do I need to be home during the solar installation?
Access needs vary by project. Ask the installer when an adult must be present, which interior or exterior areas require access, how outages will be coordinated, and who will approve field changes.
Will installing solar damage my roof?
Any roof penetration or attachment needs a documented design compatible with the roof type and condition. Require the proposal to identify attachment details, flashing, roof exclusions, workmanship coverage, and responsibility for leak investigation. Production depends on roof orientation, shade, equipment, weather, and the address-specific utility; local interconnection rules also vary between LADWP and SCE.
