Price per watt is king. Although I would rather mount and clean two panels vs three. Unless the smaller size fit better between shade items on the roof.
160 watt $115 Need to verify shipping cost.
Warranty: For panels that range from 80w to 200w, an output power of more than 90% of the minimum peak power within 10 years and more than 80% in 20 years is guaranteed.
That one is 14.7% efficient vs 19% for the Grape Solar. Seems like a big difference on that spec.
