When installing photovoltaic solar panels for maximum energy production and efficiency, the optimal direction they should face is true geographic south if you are located in the northern
To take advantage of this knowledge, you can point your solar panels southward. This gives them the best opportunity to absorb energy, powering your home and charging your batteries.
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.
It is noted that solar panels facing south and tilted between 15 and 40 degrees can improve energy output by up to 30% or more. However, factors such as roof slope and proximity to the equator may
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.
Can solar panels work effectively if they don''t face south? Yes, solar panels can still work effectively if they face east or west, though they may produce less energy overall.
The general rule for solar panel placement in the northern hemisphere is that solar panels should face true south (and in the southern, true north). This is usually the best direction
Importantly, discoveries indicate that modifying the arrangement of solar panels, specifically which way should solar panels face, can greatly improve power production during peak demand times,
Vertical or horizontal? Learn which solar panel orientation offers better efficiency and how to choose the right setup for your home.
Although south-facing is ideal in theory, practical considerations often determine panel direction. Shading from trees, chimneys, vents and adjacent buildings can make a south-facing plane
