solar pre-wired questions
Our new rv has an outdoor two pin plug-in for solar. What do I need to take advantage of it? What are it's benefits and limitations? We don't currently have any panels.

StirCrazy,
I'll probably regret this.
Poly does better in shade. Systems with series wired panels are badly affected by shade.
My tiny system (by today's standards) produces about 17 amps in perfect conditions.
It also does 6 amps in leafy shade. Mono would produce nada if parked under a leafy tree.
Mine is a series parallel with an input of 33 volts to the controller.
My cost for parts per watt in 2005 was $5, including the charge controller, panels, wiring, fuse, shipping and tax.
haha don't regret it, I think you're using poly in a different context. polycrystalline panels are made by taking the bad crystals that were supposed to be monocrystalline panels but came out cracked or fractured. Sometimes they fractur them on purpose if there specifically making poly. all these fractured chunks are put back into a oven and melted into cubes and then cut into wafers. so they are less efficient, lower life expectancy, don't do as well with heat, but cheaper to produce, and less waist int he process. also a 300 watt poly panel will be larger than a 300 watt mono panel.
what color is the surface on your panel? I am curious to know what panel you actually have. it is possible to have a poly panel with bypass diodes on every cell also, this wouldn't be the norm but why not. if that's the case it would have better results than a mono with fewer bypass diodes.
