Therefore, even though arranging solar panels horizontally might seem like it makes more shade, it actually blocks less sunlight and produces more power compared to the vertical setup.
Should a solar panel be installed horizontal or vertical?
However, it is more efficient to have a consecutive block of solar panels installed using the same orientation— either vertical or horizontal. If there is a break in your roof, or you have room for one more solar panel, then your solar contractor can install the solar panel to fit the space.
Does panel orientation affect the number of solar panels installed?
Panel orientation also has no effect on the number of panels that can be installed. Homeowners have the option to install them using differing orientations, depending on the shape of your roof. However, it is more efficient to have a consecutive block of solar panels installed using the same orientation— either vertical or horizontal.
What happens if you install horizontal solar panels?
The debris rolls right off of these panels, while it will pile up on horizontal panels. Even taking trees out of the equation, dirt will build up quickly on horizontal solar panels. If you install horizontal panels in this type of situation, make sure you clean them off often.
Are vertical solar panels better than horizontal solar panels?
In that case, vertical solar panels would be a better choice because the snow will slide down the panel. Similarly, if trees that shed leaves or acorns surround your house, you might prefer vertical solar panels. The debris rolls right off of these panels, while it will pile up on horizontal panels.
In the Southern Hemisphere, the panels should orient towards the true north. This gives all panels the most sunlight as the sun travels near the equator. Depending on your area's sun exposure, installing solar panels in a horizontal orientation might be your best option. They'll get more sunlight throughout the day, producing more energy.
Are horizontal solar panels a good choice for your home?
Depending on the climate, your roof's construction, and your solar energy needs, horizontal solar panel installation may be the right choice for your home. The amount of direct sunlight could impact the direction in which your solar panels are installed.
