I have had the panels installed for 15 months now. Last trip while on the road, we hit 450 Watts (I have 408 Watt system). We run frig off of the inverter while traveling.
I was washing the Monty this past weekend (while camping, it was a lot cooler there), and noticed that the hail that hit us almost two months ago, left little dimples.
