Difference between photovoltaic panels facing east and south

Solar panels facing east are identical to those facing west. . Orientation Impact is Massive: The difference between optimal and poor solar panel placement can impact energy production by up to 30%, making proper positioning one of the most critical factors in maximizing your solar investment return. Magnetic South Matters: Using magnetic south. . When orienting solar panels, the rule of thumb for the northern hemisphere is that the optimal orientation for solar panels is true south. However, factors such as roof slope and proximity to the equator may have some homeowners considering other directions (including north). When you're installing PV panels in the Northern Hemisphere, you'll want them facing true south to get maximum peak sunlight during the day. [pdf]
