Don if your entire roof gets paved with panels, how would you clean them?
Wait for rain?
Some possible ways:
1. Walk on them perhaps using some plywood panels.
2. Use a ladder on the side of the rig.
3. Washing poles (with water/soap flowing inside and curved/bent to access the roof. Curved brushes to clean boat hulls are common in marinas.
4. Above but adapted to a pressure washer.
5. Commercial truck washes often have cat walks to reach the trailer roof.
But regardless of solar panels roof access is required for normal maintenance and that access could also be used for cleaning.
