Customer ServiceVisible damage to your solar panels is a clear indicator that they may be defective or compromised. This can include cracks in the glass, warping or discoloration of the panels, and loose or exposed wires. Such damage can impair the panel''s ability to function correctly and may lead to safety hazards, especially during adverse weather conditions.
Customer ServiceOne common method for detecting defects in PV systems is a visual inspection. This involves physically inspecting the PV panels and related equipment for any obvious signs of damage or wear. This can include checking for cracked or broken panels, loose connections, or debris on the panels.
Customer ServiceSome panels may work better with certain types of inverters or batteries, while others may not be compatible at all. Ensuring that all system components work together seamlessly to maximize efficiency is important. Ultimately, selecting the right solar panel brand and model requires thorough research and careful consideration of multiple factors beyond price or efficiency

Customer ServiceIf you notice that your solar panel is not producing as much energy as it used to, it could be a sign that something is wrong. Another sign to look out for is physical damage to the panel, such as cracks or scratches. In some cases, a bad solar panel may also cause your inverter to display an error message.
PID is more common in older panels or those with poor grounding or insulation. To diagnose PID, you can hire a solar technician to perform a test known as the “EL imaging” test, which can identify the extent of PID and recommend suitable remedial measures.
In some cases, a bad solar panel may also cause your inverter to display an error message. To determine if a solar panel is bad, look for signs such as decreased energy production, physical damage or discoloration, hot spots, potential-induced degradation (PID), and monitoring system alerts.
This involves physically inspecting the PV panels and related equipment for any obvious signs of damage or wear. This can include checking for cracked or broken panels, loose connections, or debris on the panels. Visual inspection can also be used to check for shading issues, which can significantly reduce the output of a PV system.
Check the solar inverter for any warnings or faults. Check that the isolators are all on and that the circuit breakers have not tripped off. Check the grid voltage on the inverter display or app for over-voltage issues. Hire a solar professional or electrician to inspect the solar system.
You can detect the start of delamination by bubbles and creases on the plastic rear surface. Some owners try using duct tape and sealant to slow the process down, but such a panel isn't going to last long. So, once you've seen any of the signs of delamination, contact your installer immediately. Microcracks are another type of solar panel problem.
