The system will use Kyocera’s patented anti-dust modules which have a structure that prevents dust and water from collecting on the surface — by allowing rain water to wash off build-up via drainage channels along the frame of the module (these modules are only available to the Japanese market). This helps prevent the adverse effect of dust build-up on the module’s glass surface which decreases the power output.
