Within the solar industry, it’s common knowledge that the optimal orientation of solar photovoltaic (PV) panels in the Northern Hemisphere is typically south, to maximize electricity production over the life of the system. Recently, however, there has been much discussion, and even incentives being offered, for orienting PV systems west.
The optimum place to install solar panels usually depends on the position, inclination and its orientation towards the sun. Solar panel direction during Summer and Winter The conventional understanding is that the solar panel facing south (in locations north of the equator) will receive the most sunlight.
In California, only 9 percent of solar panels face within 10 degrees of due west, the blog says. A western orientation reduces their total output by between 10 percent and 20 percent when compared with south-facing panels, and that means less electricity for homeowners and lower earnings from net-metering.
East-west structures also tend to be used more at higher latitudes as the sun does not rise as high in the sky and panels can be placed closer to structures without shading, generating more energy from the same area. As east-west systems are installed lower to the ground, they reduce wind loads on the panels as winds pass over the array.
However it has been proven that West facing solar panels can produce more power. If you are looking to achieve cost savings by installing your own solar power system, it is highly recommended that you put some time aside and carefully analyze and determine the right location for your solar panels.
For example, in locations with time-of-use rates that are higher in the afternoon, west-facing panels could result in higher returns, as electricity produced from solar later in the day offsets higher afternoon electric rates.

Choosing PV structures: Trackers vs Fixed vs East-West
In east-west systems, solar panels are installed with half of them facing towards the east and half facing towards the west. Panels can be placed back-to-back to reduce the space between rows and allow for more modules to be installed to increase power generation.
A Full Guide to Solar Panel Placement and Installation
Solar panels can be installed on an east- or west-facing roof, but they will not be as effective as if they were installed on a south-facing roof. This is because the sun is in the southern sky for most of the day in the Northern Hemisphere. In the Southern Hemisphere, the sun is in the northern sky for most of the day.

The solar panel angle and direction should be carefully designed to minimise shading issues. The Effect of Tilt Angle on Solar Panel Efficiency. An increased solar panel tilt angle in northern states will result in higher efficiency and power generation for the entire rooftop solar system, but there''s a caveat. As the tilt angle increases, so ...
Why the tilt and direction of your solar panels matter
I have a solar system, 16 panels @190 watts per panel and 3kw inverter. 7 panels face north and 9 panels face west. According to the electrician they are wired even 8/8, which means 1 panel facing west is linked with 7 facing north. A neighbour has 15 panels @205 watts per panel all facing west, and a 2.5 inverter, his system produces on average 3 – 4 kws …
