Summary

150 W from A compact frame, short cover

What it is: a 150 W, 12 V TOPCon glass panel for RV, cabin, boat and small off-grid systems
The trade-off: 150 W from one 44 x 26.4 in panel and a long output guarantee, but just 20 percent module efficiency
Not checked: Rich Solar publishes no bypass diode count
Look elsewhere for: a narrow panel for strips of roof between fixtures

Strengths

Long output guarantee
Sealed junction box and connectors
Well rated by Amazon buyers

Drawbacks

Module efficiency only on the middle rung
Workmanship term differs across Rich Solar's pages
Longer workmanship term is prorated
Bypass diode count not published
Some owners report output below the rating
