The gain is largest exactly when you need it — cold, bright winter days, when panel voltage is high and the sun is low. On a 260W array that can be the difference between the fridge running on solar and the fridge running on the battery.\u003c\/p\u003e\u003ch3\u003eSizing to the array\u003c\/h3\u003e\u003cp\u003e260W at 12V is the ceiling. Two 100W panels is comfortable; two 175W panels is not, and you would be clipping output at the very times the roof is producing well. Size the controller to the array you intend to end up with, not the one you are starting with — upgrading the panel is easy, replacing the controller means redoing the wiring.\u003c\/p\u003e\u003ch3\u003eBefore you order\u003c\/h3\u003e\u003cp\u003eIP32, so keep it in a dry cupboard.
