MAINTENANCE
Topray Solar crystalline solar modules require minimal maintenance. Given a sufficient tilt (at least 15°), it is not generally
necessary to clean the modules (rainfall will have a self cleaning effect). Regular maintenance is required to keep modules
clear of snow, bird droppings, seeds, pollen, leaves, branches, dust and dirt spots. When there is a noticeable buildup of
soiling deposits on the module surface, wash the PV array using water without cleaning agents and a gentle cleaning
implement (a sponge), during the cool of the day. Dirt must never be scraped or rubbed away when dry, as this will cause
micro-scratches. If snow is present, a brush with soft bristles can be used to clean the surface of the module.
Once a year the modules need to be inspected for tightness of screws securing the modules to the racking frame. The
general condition of the wiring needs to also be inspected. Loose hardware could result in damage to the panel. Strong
wind conditions could loosen the mounting devices.
Do not change the PV components (diode, junction box, plug connectors).
If you need electrical or mechanical inspection or maintenance, it is recommended to have a licensed, authorized
professional carry out the inspection or maintenance to avoid hazards of electric shock or injury.
