Cleaning versus maintenance, which one do you need so ensure efficiency of your solar panels? The answer is you need both. Cleaning simply entails washing the panels (like windows), while maintenance involves technical checks
and should be done by a professional.

Cleaning: Is it necessary?
If you start noticing reduced output at a time, dirty panels could be the main
factor. The rain won’t do the trick alone, so cleaning is necessary. But remember
that cleaning shouldn’t cost much. If you have a smaller home installation, you
can do it yourself. But for installations that cover larger areas, getting
professional help is a wise option. The rule is, the stickier the buildup, the more
likely it is that you’ll need cleaning tools and supplies to wipe your panels down
from up close.

Maintenance: When do you need it?
How often should you get your solar power system inspected or maintained? Your solar power system should be inspected and tested by an accredited Clean Energy Council professional every 5 years.
Australia’s Clean Energy Regulator (CER) advises that a good service should
make sure that:

● solar panels are clean, secure and free of defects
● no parts have deteriorated/corroded
● vents are free of debris
● switches don’t have any defects
● wiring hasn’t been damaged or hasn’t deteriorated
● electricals are checked to make sure all components are operating as intended
● fittings and cables are securely attached
● the inverter display panel for recorded faults is working
● access to the isolator switches hasn’t been impeded
● emergency procedures for shutdown and isolation are clearly displayed

Clean and maintain your panels. Enjoy that sense of peace and satisfaction knowing you’ve done something to keep your family safe, and your investment functioning efficiently.
