Quick Answer
To prepare your solar system for seasonal changes, ensure a thorough cleaning of panels in the spring, adjust the system's angle and orientation in the summer and winter to optimize energy production, and inspect panels for winter debris in the spring.
Cleaning the Solar Panels
Cleaning solar panels in the spring is crucial to remove winter debris and dirt that have accumulated on the surface. Use a soft-bristled brush or a low-pressure hose to clean the panels, starting from the top and working your way down. Avoid using high-pressure hoses, which can damage the panels or their connections. For tougher debris, mix a solution of 1 part white vinegar to 2 parts water and apply it to the panels using a soft cloth. Rinse the panels thoroughly with water.
Adjusting System Angle and Orientation
In the summer, the sun’s rays are more direct, and the solar panels should be adjusted to track the sun’s movement, typically between 30° and 60° angle. This allows for maximum energy production during the peak sun hours. In the winter, the sun’s rays are lower in the sky, and the panels should be adjusted to a lower angle, around 20° to 30°, to capture the available sunlight. Be sure to adjust the system’s orientation to ensure the panels face true south in the northern hemisphere.
Inspecting and Maintaining the System
Before the winter season, inspect the solar panels and their connections to ensure they are secure and free of debris. Check the system’s inverters and monitoring equipment to ensure they are functioning properly. During the winter, inspect the panels for snow and ice accumulation, and consider using a snow rake or a soft-bristled brush to gently remove debris. Regularly inspecting and maintaining the solar system will ensure optimal performance throughout the year.
