Solar Repair & Maintenance in Alhambra, CA

Normal aging causes a gradual decline of about 0.5 to 1% per year. However, dirt buildup, microcracks, corrosion, and electrical issues can accelerate efficiency loss beyond the expected rate. 

Yes, cracked panels can still produce electricity, but cracks reduce efficiency and can worsen over time. They also create potential safety hazards and should be inspected by a professional. 

Common signs include error messages on the display, unusual noises, reduced energy production, or the system shutting down frequently. Most inverters last 10-15 years and may need replacement before the panels. 

Not if done correctly. Solar panels need to be temporarily removed for roof work, which requires professional handling to avoid damage and maintain warranties. 

Standard grid-tied systems shut off during outages for safety reasons. To maintain power during outages, you need a battery backup system installed with your solar array. 

Several factors could be responsible: reduced panel efficiency from dirt or damage, inverter problems, increased energy usage, or changes to net metering rates that affect your billing credits. 

Most solar panels are warrantied for 25 to 30 years and continue producing electricity beyond that, though at reduced efficiency. Regular maintenance helps maximize their lifespan and performance.

Yes, birds, squirrels, and rodents can nest under panels, chewing wires and causing damage. Critter guards prevent animals from accessing the space beneath your panels while allowing airflow. 

Minor repairs typically don’t require permits, but major work involving electrical or structural changes does. A licensed contractor can help determine if your repair needs permitting.
