However solar panels can be orientated on any roof that faces south of either east or west.
Which way should solar panels face in california.
To understand this rationale consider the alternatives.
It is at this location that your panels will receive the maximum sunlight throughout the day.
For the last few decades conventional wisdom among solar experts has held that south is the best direction to face solar panels for installations in the northern hemisphere.
To correct the compass reading your solar installer will calculate the magnetic declination of your site.
Solar south or geographic south.
The conventional wisdom in the northern hemisphere is that the best direction to face solar panels is south since that is generally where they d receive the most sunlight.
However there is a difference between magnetic south and true south that must be considered.
Face panels west for tou ratepayers for solar panel owners that are under a tou payment system the best way to save money on your electric bill is to produce more energy during peak hours than during off hours.
Consequently the direction that a solar panel faces determines how much energy it can produce.
This means that your solar panels will be put in a unique direction specifically to maximize energy production between this time range.

Photovoltaics produce power when the angle at which the sun s rays hit the panel surface the angle of incidence is small or when light strikes the panel as close to perpendicular as possible.
The direction solar panels should face is true south a k a.
