IV. MAINTANIENCE
1.
No routine maintenance is required.
2.
Grape Solar recommends that periodic inspection of the PV system for tight electrical and mechanical
connection and free of corrosion should be performed.
3.
Periodic cleaning of modules is not required, but is recommended, as periodic cleaning can result in
better performance of the PV system, especially in regions with low levels of annual precipitation.
4.
Do not remove the dirt by scraping or rubbing away from the module front surface when dry as this
may cause micro-scratches on the glass and lead to module performance degrading.
5.
Water can be used for regular washing or rinsing of the module front glass to remove dust, dirt or other
deposits.
6.
To remove ingrained dirt, first rinse off area and let soak for a short period of time (5-minutes). Re-wet
and use a soft sponge or seamless cloth to wipe glass surface in a circular motion. Mild detergent or
glass cleaner may be used to clean the ingrained dirt, but harsh cleaning materials such as scouring
powder, steel wool, scrapers, blades, or other sharp instruments must not be used to clean the module.
Use of such materials will void the product warranty.
7.
Always wear rubber gloves for electrical insulation while maintaining, washing or cleaning panels.
