Which Solar Panel Direction (Orientation) Is Best?
East Orientation: East-facing solar panels are similar to west-facing ones in producing around 15% less electricity overall than north-facing panels, but produce more electricity in the

While most solar companies default to "south-facing is best," the reality is far more nuanced. Your optimal panel direction depends on factors most installers never even consider.
In the Southern Hemisphere, the main panel orientations to consider are north-south and east-west, each with its unique advantages and implications. Choosing the right orientation for solar panels
To effectively utilize the sun''s power, homeowners in the northern hemisphere need to know which way to point solar panels, and the gold standard is to orient them to face true south.
Solar panels should face true south, not magnetic south. The difference between these directions, called magnetic declination, can vary by up to 30 degrees depending on your location.
Solar inverters have what is known as a ''start up'' voltage, this is the minimum amount of energy need to kick a string of panels into action. So, the panels on the east side of the house will
Learn everything about solar panel wiring in 2025 — from series vs parallel connections to inverter compatibility, MPPTs, wire types, and safety rules.
Master solar panel wiring with this in-depth guide. Learn how to configure series and parallel connections, calculate voltage and current, and safely integrate inverters, charge controllers, and
If you want to make the most of your solar installation, you should choose the proper orientation and tilt for PV panels. Our guide will help you do just that.
In the northern hemisphere, the general rule for solar panel placement is, solar panels should face true south (and in the southern, true north). Usually this is the best direction because solar panels will
