Introduction
Over the past few days, we’ve had some rain. While it may have eased the fires a little, the danger hasn’t gone away, and given the way things are now, that threat will likely linger long after the skies clear.
Wildfires don’t just threaten lives and homes, they also test the resilience of everything we’ve built in remote places. For those of us who live with or maintain off-grid solar systems, the fire’s aftermath brings new questions: What, if anything, can be salvaged? Can a melted charge controller be rebuilt? Is it safe to reuse panels that have been scorched?
The answers aren’t always straightforward. In recent years, wildfires across North America have destroyed off-grid cabins from British Columbia to California. While many systems are reduced to scrap, some owners have found ways to recover valuable parts, even using the loss as an opportunity to design a better, more resilient setup.
Real-World Examples ( Found Through Internet Search )
1. Cariboo Region, BC – Panel Survivors
In 2021, a wildfire swept through a lakeside cabin community in the Cariboo. One cabin owner found their battery bank and inverter completely destroyed, but surprisingly, most of the rooftop solar panels survived. The tempered glass was intact, and a test with a portable solar analyzer confirmed they were still producing near-rated output. They were later installed on the owner’s rebuilt cabin, saving thousands in replacement costs.
2. California Sierra Foothills – A Lesson in Heat Damage
A family lost their off-grid home during the 2020 fire season. Their ground-mounted solar array, located about 50 feet from the main structure, avoided direct flames but suffered intense radiant heat. Output testing revealed microcracks in several panels, reducing efficiency. While a few panels were salvageable, the rest were recycled. The owner later decided to place new panels farther from the cabin in a more open, defensible space.
3. Central Oregon – Salvaging Mounts and Wiring
In Oregon’s 2022 fire season, a remote hunting cabin burned to the foundation. All electronics and batteries were gone, but the heavy-duty pole mount for the panels was still structurally sound. The owner salvaged the mount and much of the conduit and wiring, reusing them in a new installation. They also switched to a wall-mounted lithium battery inside a fire-resistant enclosure.
Assessing and Recovering Your Off-Grid Solar System
A practical guide to what you can safely do (and what to leave to the pros)
When a wildfire or cabin fire strikes, the damage goes far beyond charred walls and lost belongings. For off-grid homes, a damaged solar system can mean losing your only source of reliable electricity. Even if some equipment looks untouched, heat, smoke, and water damage can compromise safety and performance. This guide walks you through the safest, most effective steps to take after the fire is out.
1. Safety First — Do Not Rush In
Do not enter the property until fire officials confirm it’s safe. Hidden hazards include unstable structures, lingering hotspots, sharp debris, and toxic fumes from burned materials. If in doubt, stay out.
2. Document Before You Touch Anything
Take detailed photos and videos of your solar equipment and the surrounding damage. This visual record is vital for insurance claims and will help technicians understand the full scope before they arrive.
3. Contact Your Insurance Provider and Installer
Call your insurer as soon as possible and inform your solar installer or a qualified solar technician. Many insurance companies require inspection reports and will base decisions on whether components should be repaired, replaced, or written off. Avoid moving or dismantling anything until these parties are informed.
4. Evaluating Solar Components After a Fire
Solar Panels
If the panels weren’t directly burned, they may still be salvageable, but only after thorough testing. A qualified technician should run an I–V curve test and infrared imaging to detect hidden performance issues or insulation failures. If any defects are found, replacement is the safest choice.
Inverters & Electronics
Even if they look intact, inverters, charge controllers, and monitoring equipment can suffer from contamination and internal damage. A professional should open them up, clean them, and run bench tests to ensure safe operation. If there’s any uncertainty, replace them.
Batteries
Treat all fire-exposed batteries as potentially hazardous. Contact the manufacturer for guidance and have the batteries tested in a controlled facility. In many cases, replacing them is both the safest and most reliable option.
Racking & Hardware
Mounting systems may survive, but heat can warp metal and weaken fasteners. A technician can check structural integrity, clean any salvageable parts, and replace compromised hardware.
5. Why Professional Help Matters
Fires can cause hidden damage that isn’t visible to the untrained eye. Attempting to reuse compromised components can lead to electrical hazards, reduced system performance, or even another fire. Professionals have the tools, training, and safety procedures to properly evaluate and restore your system.
Conclusion
A wildfire can erase years of work in minutes. While some solar components may survive, safety should always come first. Salvaging parts can save money, but the real value lies in the lessons learned, from placing arrays farther from structures to investing in better protective enclosures for electronics.
Rebuilding after a loss is never easy, but with the right approach, it’s possible to create a system that’s not just restored, but stronger and better prepared for whatever nature throws its way.
