Summary

Standard 100 W panel, short workmanship cover

What it is: a 100 W, 12 V glass-framed panel for vans, campers, boats and small off-grid systems
The trade-off: a sealed junction box and a long output guarantee, but the lowest output rung and under 19 percent module efficiency
Not checked: Rich Solar publishes no bypass diode count
Look elsewhere for: more watts from the same roof area

Strengths

Long output guarantee
Sealed junction box and connectors
Glass-and-aluminum build for harsh conditions
Well rated by Amazon buyers
Leads pre-attached for plug-in wiring

Drawbacks

Low efficiency for its footprint
Low output for a rigid panel
Workmanship term differs across Rich Solar's pages
Longer workmanship term is prorated
