I'm setting up a small system for my son's house which will have two 300 watt panels. A friend is saying they need to be at an 11º angle equal to our distance north of the equator. Thew house sits facing south southeast and the sun rises from behind the left rear corner of the house in summer months and sets on the right front corner, which are the cooler, rainier months here and in the winter months which are hotter and sunnier rises on the front corner and sets about 40º in front of the right side.
I think the panels should be flat to increase production in the cloudier months and not angled to the hotter, stronger months when the batteries will probably be topped up before noon.
As the seasons are somewhat backwards from the typical effects of the north, does this make sense? Everything I see here has the panels tilted to the south but to me it seems like they're not getting the benefit they need in the times when they need it..
