Performing General Maintenance
Follow these simple routines to ensure many years of service and optimal
performance of your solar energy system.
1. Keep the heatsink clear of dust and debris.
2. Clean the PV array, during the cool part of the day, whenever it is visibly
dirty.
3. Periodically inspect the system to make sure that all wiring and supports are
securely in place.
4. On a sunny day near noon on March 21 and September 21 of each year,
review the output of the system and compare with previous year’s reading.
Maintain a log of system performance readings so that you can recognize
when system performance becomes inconsistent.
