Hi tpi,
I believe solar panels work, or they don't. So long as there is an ability to exchange a non working panel I'd go on best price.
I would want as many diodes per panel as possible, and I'd probably favor Poly over Mono.
Why?
"Monocrystalline cells have a higher efficiency than polycrystalline cells due to the structure being made from one large crystal as opposed to many small ones. In addition to having an overall better efficiency, monocrystalline panels can perform up to 10% better than polycrystalline panels in high ambient temperatures."
I think the confusion about poly vs mono comes from different manufacturer quality. A good manufacturer of a poly panel is going to outperform a poor quality mono panel. In the lab with highest quality poly vs highest quality mono, mono wins. The deciding factor for a consumer is quality of manufacturing I guess...figuring out which panel has higher quality cells, be they poly or mono.
