Question on Shaded Solar?


stevekk

Recommended Posts

I am still trying to plan my future 300 watt Solar for my Class C.

2 ea 100 watt on roof. 1 ea portable 100 watt.

What happens when I am parked in the shade and the 2 panels on the roof are 100% shaded?

Or partially shaded?

Will my portable 100 watt work OK in full sun?

 

The 100 watt portable, I plan to install on the sidewall of MH over the bathroom window where I can "hinge" to act like an Awning

or remove to make it portable.

 

Thanks..

As long as you wire the panels in parallel shading will only impact the power output of the shaded panel(s) so you'd get full power from any in the sun.

 

I think most panels come with blocking diodes today but you'd want to make sure yours have them, they keep your working panels from wasting power through shaded panels.

First rule of computer consulting:

Sell a customer a Linux computer and you'll eat for a day.

Sell a customer a Windows computer and you'll eat for a lifetime.

I have one 125 watt panel permanently mounted on the roof and an 80 watt and 180 watt mounted on the side that can be removed. All are 12 volt connected in parallel. I have had no problems.
