14. Maintenance
Modules should be inspected annually for loose electrical connections, poor grounding connections, and loosened mechanical
fastening to the racking structure. A module tilt of at least 10 degrees will help rainfall clean the modules naturally. Should
cleaning of the modules become necessary, wet the glass surface before wiping with a soft sponge to prevent micro-scratches.
Snowfall may be cleared using a soft bristle brush. If hand cleaning is not possible, pressure washer cleaning of module glass
is permitted only when complying with all of the following restrictions:
1. Cleaning fluid: water at normal ambient temperature
2. Machine pressure rating: 13.1 MPa
3.
Machine flow rating: ≤7 L/min
4.
Output nozzle distance to solar panel: ≥30 cm
5.
Spray tip water divergence: ≥ 15°
6. Do not clean it with chemical.
7. Do it in the morning or in the evening.
There are no user-serviceable parts in the junction boxes. Do not open the junction box or change intra-module
wiring as all wiring connections are performed in the factory. The electrical connectors cannot be used as a live
disconnect. Modules may only be connected and disconnected when current is not flowing (open circuit voltage
conditions). Always observe proper precautions when connecting or disconnecting modules exposed to light
since hazardous voltage may be present.
