Welcome from Ecuador! I lived in the Southern Deserts and grew bananas there - I wasn't using shadecloth, but had them planted under Acacias. What everybody has said holds - deep mulch the pits, then make sure your irrigation system works. Mine didn't and so I had to carry water for the nanners three times a day.... Worth it for the fruit, though. I had Cavs, Dwarf Cavs, Oritos, Plantains, and Jamaican Reds (which are called Rojitos here.)

I'm not sure how windy your location is; my desert just howled for six months, so I ended up planting clumping bamboos for a windbreak.

I'll add that it's more water-efficient for the plantings if you plant in rings rather than rows. This way the older trees provide shade for the pups, and water doesn't evaporate as easily.
