It depends on whether the price you're getting for that power is sufficiently different between winter and summer; because if your contract has a fixed price per kWh then optimizing for winter (which gets you a bit more power in winter, but a lot less power in summer - because in summer the "angle multiplier" gets applied to much more sunlight) is a bad decision.
