Learn how to troubleshoot the SunPower Maxeon Low Light Production error during winter months.
Low light production can occur due to shading, dirt accumulation, or snow cover on panels. These factors reduce the amount of sunlight reaching the solar cells.
To improve performance, ensure panels are clear of snow and debris. Additionally, consider adjusting the angle of the panels to maximize sunlight exposure.
The SunPower Maxeon inverter is designed to optimize energy production based on various environmental conditions. During low light conditions, such as those common in winter, the inverter may trigger a fault due to insufficient voltage from the array. This can occur when the string voltage falls below the inverter's operational limits, often due to shading, snow accumulation, or low irradiance levels. The inverter's ground fault detection system may also activate if moisture infiltrates the junction box, causing safety protocols to engage and limit functionality.
Homeowners may notice a significant drop in energy production during winter months, particularly on overcast days. The inverter may display a warning light or alert on the monitoring app indicating low light production. Additionally, performance data may show a marked deviation from expected output based on historical data.
For any electrical work or troubleshooting, always consult a licensed electrician or certified solar installer to ensure safety and compliance with local codes.
To prevent low light production issues in the future, regularly clean the solar panels to remove snow, leaves, and debris. Schedule routine maintenance checks to ensure all electrical connections are secure and that the inverter settings are appropriate for seasonal changes. Additionally, consider installing a monitoring system that alerts you to performance drops before they become significant.
