DIODES

Bypass Diodes

When the modules in series strings are shaded partially, it may cause a reverse￿voltage￿across￿cells￿or modules, because the current from other￿cells￿in the same series is forced to flow through the shaded area, and then undesirable heating may occur. ￿The use of a diode to bypass￿the￿shaded￿area￿can minimize both heating and reduction of array current.

All SANYO modules are equipped with factory installed bypass diodes. The factory-installed diodes provide proper circuit protection for the systems within the specified system voltage, so that you don’t need any other additional bypass diodes. Contact your authorized SANYO distributor or dealer for proper diode type, if necessary to add or change diodes due to system specification.

MAINTENANCE

Some maintenance is recommended to maintain optimal output performance of solar cell modules. If the module surface becomes dirty, it may cause reduction of output power. It is recommended to clean the surface with water and soft cloth or sponge. A mild non-abrasive detergent may be applied for the persistent dirt. And it is also recommended to inspect the electrical and mechanical connections annually.

If you need electrical and mechanical inspection or maintenance, it is recommended to have the authorized professional carry out the inspection or maintenance to avoid the hazards of electric shock or injury.
