Solar panels are made to be strong and resilient to various environmental factors. However, like any other system, they may develop wear and tear that requires maintenance or repairs over time. Recognizing the warning indicators of solar panel failure is essential to maintaining peak performance and averting more significant problems later.

Visual Inspection

Regular visual examinations of your solar panels can identify possible issues. Examine the panels for any physical damage, such as cracks or discoloration. Fractures or cracks can reduce the panel’s effectiveness and let moisture in, which could lead to more damage.

Decreased Energy Output

Check your solar system’s energy output regularly. If you observe a noticeable and prolonged drop in energy production, there may be a problem with one or more panels. Damage, soiling, or electrical issues are a few possible causes.

Unusual Noises or Smells

Even though solar panels are meant to run quietly, any odd sounds or smells from the system must be looked into immediately. Odors such as crackling, buzzing, or burning may indicate electrical problems or fire hazards that must be addressed immediately.

Shading or Obstructions

Solar panels need direct sunlight to produce electricity efficiently. If you observe continuous shade or obstructions like overgrown trees or recently constructed buildings, the panels may produce less energy and eventually sustain damage. Provide prompt attention to any shading concerns.

Age and Wear

Solar panels can deteriorate with age and exposure to the elements, just like any other piece of equipment. Suppose they are nearing the end of their anticipated lifespan, usually 20 to 25 years. In that case, a professional must inspect your panels to evaluate their condition and determine whether repairs or replacements are required.


Solar panel problems must be promptly resolved to preserve peak performance and prevent additional damage. If you observe any of the symptoms mentioned above, have a qualified solar technician examine your system and suggest the best action.
