Summary

Short 24 V panel, middling module efficiency

What it is: a 175 W, 24 V N-type rigid panel in a near-square frame, sold with a 20 ft extension cable set
The trade-off: fits a short roof section, but its module efficiency is far below the cell figure marketed
Warranty: Rich Solar's own pages give three different product terms; the shortest is scored
Look elsewhere for: more watts per square foot or a 12 V-only system

Strengths

Short, near-square frame for tight roofs
Long power-output guarantee
Sealed junction box and connectors
Extension cable set in the box
Suits 24 V banks from one panel

Drawbacks

Module efficiency well below the marketed cell figure
Warranty terms differ across Rich Solar's own pages
No split-cell layout or station adapters
Modest output for its frame size
