The purpose of these cleaning guidelines leakage of electrically active parts can result in is to provide general information for cleaning injury. Canadian Solar modules. Professional installers should read these guidelines carefully and strictly follow these instructions. · Ensure that the array has been disconnected from other active components (such as inverter or combiner boxes) before starting with the cleaning. Failure to follow these instructions may result in death, injury or property damage to the photovoltaic module. Damages induced by inappropriate · Wear suitable protection (clothes, insulated gloves, etc.). cleaning procedures will void Canadian Solar Inc. warranty. HANDLING NOTICE SAFETY WARNING · Use a proper cleaning solution and suitable cleaning equipment. · Cleaning activities create risk of damaging the modules and array components, as well as increasing the potential electric shock hazard. · Cracked or broken modules represent an electric · Do not use abrasive or electric cleaners on the module. · Particular attention should be taken to avoid the shock hazard due to leakage currents, and the risk module backsheet or frame to come in contact of shock is increased when modules are wet. with sharp objects, as scratches may directly affect Before cleaning, thoroughly inspect modules for product safety. cracks, damage, and loose connections. · Do not use de-greasers on the module. · The voltage and current present in an array during daylight hours are sufficient to cause a lethal electrical shock. · Do not immerse the module, partially or totally, in water or any other cleaning solution. · Do not use cleaning corrosive solutions containing acid, alkali, acetone, or industrial alcohol. · Canadian Solar Inc. recommends to avoid rotating brush cleaning methods, as they could create micro-cracks in the PV modules. EN-Rev IM/GN-AM-EN/A9 Copyright © October 2017. Canadian Solar Inc. | 25 · Rev A2 was amended and released in December, 2014 · Dirt must never be scraped or rubbed away when · Rev A3 was amended and released in August, 2015 dry, as this will cause micro-scratches on the glass · Rev A4 was amended and released in March, 2016 surface. · Rev A5 was amended and released in June, 2016 · Rev A6 was amended and released in December, 2016 · Rev A7 was amended and released in March, 2017 OPERATION PREPARATION · Rev A8 was amended and released in June, 2017 · Rev A9 was amended and released in October, 2017. · Noticeable dirt must be rubbed away by gentle cleaning-implement (soft cloth, sponge or brush with soft bristles). · Ensure that brushes or agitating tools are not abrasive to glass, EPDM, silicone, aluminum, or steel. · Conduct the cleaning activities avoiding the hottest hours of the day, in order to avoid thermal stress on the module. We recommend the following to be used: · Water with low mineral content · Near neutral pH water · The maximum water pressure recommended is 4 MPa (40 bar) CLEANING METHODS Method A: Compressed Air Canadian Solar Inc. recommends cleaning the soft dirt (like dust) on modules just with compressed air. This technique can be applied as long as the method is efficient enough considering the existing conditions. Method B: Wet cleaning If excessive soiling is present on the module surface, a non-conductive brush, sponge, or other mild agitating method may be used with caution. · Ensure that any brushes or agitating tools are constructed with non-conductive materials to minimize risk of electric shock and that they are not abrasive to the glass or the aluminum frame. · If grease is present, an environmentally friendly cleaning agent may be used with caution. AMENDMENT EDITIONS AND DATES · The first edition Rev A1 was released in April, 2014. ">
