About The Project

In this technical restoration project in Highland Park, the NeighborSun team intervened on a solar system that was experiencing a critical drop in performance due to sediment buildup and wiring faults. We performed a deep cleaning and a 25-point inspection to ensure every panel operates at peak capacity, protecting the client's long-term investment in Los Angeles.

We use thermal diagnostic tools to identify "hot spots" and micro-cracks that are not visible to the naked eye. At NeighborSun, we understand that California's climate, with its dust and drought periods, can reduce efficiency by up to 30%. Our repair and maintenance service not only corrects current faults but prevents costly damage to inverters and optimizes current flow.

Following the intervention, the system regained its nominal efficiency, allowing the homeowner to maximize net metering credits. NeighborSun establishes itself as the leader in solar maintenance in Southern California, offering preventative service contracts that ensure your system works perfectly for decades to come.

The Challenge Of The Project

The primary challenge was identifying an intermittent fault in the power optimizer that caused random system shutdowns. Thanks to NeighborSun's technical expertise, we were able to isolate the defective component and replace it under warranty, saving the client from paying for a full replacement. This level of detail is what sets us apart in the Los Angeles market.
