Los Angeles fire raises new concerns over California’s growing solar fire risk

Rooftop solar faces fresh safety questions

Solar panels have become a common sight across America, helping families cut electric bills while using cleaner energy. But after a major warehouse fire in Los Angeles, experts are taking a closer look at how rooftop solar systems are designed and installed.

The fire does not mean solar panels are unsafe. Instead, it has highlighted the need to improve how heat is managed around rooftop installations. Engineers say better designs today could help reduce risks in the future while keeping the many benefits that solar power offers.

A warehouse fire drew attention

A large fire broke out on June 17 at a cold storage warehouse in the Boyle Heights neighborhood of Los Angeles. The blaze burned for days and produced thick smoke that spread across the area.

The incident quickly caught the attention of people across the solar industry. Experts say the fire is an important reminder that as rooftop solar becomes more common, safety practices and building designs must continue improving alongside the growing number of installations.

Why experts are speaking up

Lawrence Shaw, a solar power engineer and owner of Higher Powered LLC in Arizona, believes the Los Angeles fire should encourage the industry to review how rooftop systems are built.

Shaw explained that every technology carries some level of risk as it becomes more widely used. Instead of creating fear, he believes the focus should be on identifying weaknesses, improving designs, and making future solar installations safer for homeowners, businesses, and emergency crews.

Heat may play a bigger role

One concern raised by Shaw is the amount of heat that can build up beneath rooftop solar panels. In places like California and Arizona, where summer temperatures can become extremely high, limited airflow under panels may allow heat to collect near the roof surface.

Engineers believe better ventilation could help reduce this problem. Allowing more air to circulate beneath solar panels may lower temperatures and improve overall safety without reducing the clean energy these systems provide.

An older model projected more PV fires

Lawrence Shaw and John Balfour developed a model using reported fire data and other information to estimate future photovoltaic-related fires.

Published in 2021, the model projected 122 PV-related fires in California in 2030, with many projected incidents concentrated in the Southwest. The figure is a modeling estimate based on historical data, not an official U.S. Fire Administration forecast.

The projection helped highlight the need for better fire reporting, installation practices, monitoring, and research as solar deployment expands.

Little-known fact: Solar panels can help keep buildings cooler by shading the roof and reducing heat reaching the attic.

Solar still offers major benefits

Even with concerns raised by the Los Angeles fire, experts continue to support solar energy as one of the best ways to lower electricity costs and reduce pollution. Millions of homes and businesses across the United States rely on rooftop systems every day without experiencing problems.

Experts say the goal is not to slow solar adoption but to make it even safer as more systems are installed. By improving designs and following updated installation practices, the industry can continue delivering clean, reliable energy while reducing potential risks.

Why proper installation matters

A rooftop solar system is only as good as the way it is installed and maintained. Professionals say careful planning, quality equipment, and regular inspections all help reduce the chances of electrical issues or overheating.

Building owners also play an important role by scheduling inspections if they notice damaged panels, loose wiring, or other unusual conditions. Routine maintenance allows installers to identify potential problems early before they become larger and more expensive to fix.

Better airflow could make a difference

Shaw believes one practical improvement is increasing the space between solar panels and the roof. A larger air gap allows heat to escape more easily instead of becoming trapped beneath the panels. Better airflow may help reduce temperatures during hot summer days.

Although some homeowners prefer lower profile installations for appearance, engineers say safety should remain the highest priority. Finding the right balance between design and performance can help create rooftop systems that are both attractive and more resilient.

Fun fact: Many modern rooftop solar systems include rapid shutdown features that improve firefighter safety.

Better reporting can improve safety

Another recommendation is creating more consistent records whenever a solar-related fire occurs. Knowing if a fire started in a panel, an inverter, a battery, or another part of the system can help experts identify patterns and improve future designs.

Better reporting also gives firefighters, manufacturers, and regulators valuable information. Over time, this shared knowledge can lead to stronger safety standards, better equipment, and installation practices that lower risks while supporting continued growth in renewable energy.

New ideas are gaining attention

Engineers are also exploring alternatives that reduce heat buildup while still producing clean electricity. One option is installing solar panels over parking lots instead of directly on rooftops.

Another promising tool is the use of drones equipped with thermal cameras. These inspections can quickly detect unusually hot areas that may signal developing problems. Finding those issues early allows repairs to be made before they become more serious or create safety concerns.

Safety rules may keep evolving

As rooftop solar continues to expand across the country, many experts believe building codes and installation standards will continue to improve. Updating guidelines as new information becomes available can help reduce future risks while supporting the growing demand for clean energy.

Experts also encourage ongoing research into how heat affects rooftop systems in different climates. Better testing and improved designs could help make future installations even safer.

A balanced path forward

The Los Angeles warehouse fire has sparked important conversations, but it has not changed the fact that solar energy remains a valuable source of clean electricity. Engineers, installers, firefighters, and regulators all share the same goal of making rooftop systems as safe and reliable as possible.

As new technologies, better installation methods, and stronger safety standards continue to develop, homeowners and businesses can feel more confident about investing in solar. Learning from incidents and applying those lessons is one of the best ways to strengthen the industry’s future.

Cleaner energy with safer solutions

Solar energy continues to play an important role in America’s clean energy future. The lessons from the Los Angeles warehouse fire remind everyone that improving safety is just as important as expanding renewable energy.

Simple design changes, better inspections, and updated standards could help reduce risks while allowing more families and businesses to benefit from rooftop solar.
