The Microinverter system requires virtually no maintenance and provides you with
trouble-free energy production.
Visually inspect the modules (panels), especially after storms, hail and high winds
An inspection from the ground, with binoculars if needed, is usually sufficient. Check
the array for dust, debris, leaves, and other soiling. Clean solar modules generate
maximum energy harvest.
Some geographic regions do not have much dust, debris, and pollution, so solar
modules remain relatively clean and maintain optimum energy performance. In other
areas, rain and snow naturally clean modules and help maintain performance.
Perform an annual check
In order to ensure optimum module performance, Joule recommends the
following:
• If necessary, the glass front of the module can be cleaned with water and a soft
sponge or cloth. A mild, non-abrasive detergent can be used to remove more stub-
born stains.
• Check the electrical and mechanical connections periodically and make sure they
are clean, safe, complete and secure.
• In the event of a problem, consult with a licensed/qualified person
Talk to your solar professional about performing a yearly check. Your solar profession-
al can inspect your array and verify that the electrical and mechanical connections are
intact and working efficiently.
Monitor system performance
An add on
Photovoltaic Envoy
can be purchased to check energy production from
your Enphase Microinverters on MyEnlighten to compare the month-to-month, or the
year-to-year performance of your system.
For example, use the MyEnlighten energy grid or generate a report and compare the
energy production for one month to the same month in the previous year. Is it the
same or lower? If lower, did cloud cover reduce energy production? If not, you may
want to perform a visual inspection of your array and check for debris.
