The vast majority of people don’t think of solar panel direction when they are looking to have solar panels installed.

The average person thinks that as long as there is a sunny spot on their roof, they are good to go.

However, the direction that your solar panels are facing can have a significant impact on how much power they produce.

Solar panels need to be facing the sun in order to work most effectively.

In this article, we will discuss the ideal direction and orientation for solar panels and how to maximize your panel’s output.

Choosing The Right Location And Solar Panel Direction

Not only do your panels need to be facing the right direction, but they also need to be at the right angle.

The angle of your panels is just as important as the direction.

This will ensure that they are absorbing the maximum amount of sunlight and converting it into energy.

Solar panel location

The performance of a solar panel system is determined by the direction it faces. A system that faces East or West will produce 15-20% less energy than one facing directly South.

Any nearby buildings, trees, or chimneys may cast shade on your roof and have an impact on its efficiency.

Finding a shaded location is ideal, but sometimes shading can’t be avoided. If this is the case, there are still options to ensure that your system is as efficient as possible.

In these cases, a system with micro-inverters might be the right choice for you. With this technology, each panel is able to operate independently, meaning that even if one or two are shaded, the rest of your system can still perform at its best.

Solar panel direction

The optimum angle for solar panels in the Northern Hemisphere is between 30 and 40 degrees from horizontal.

In the Southern Hemisphere, it is between 20 and 30 degrees.

This tilt allows the panels to capture the most sunlight possible throughout the day.

It also helps to protect the panels from dirt, dust, and debris that can accumulate on their surface and reduce their efficiency.

Does it matter which direction solar panels face?

Yes it does! The angle and direction of your panels have a direct impact on how much power they produce.

To get the most out of your system, it is important to consult with a professional to determine the best location and orientation for your solar panels.

They will be able to take into account factors such as the shade from nearby buildings, trees, and other obstructions.

They will also be able to advise you on the best tilt angle for your panels, based on your location.

Solar panel direction by zip code/post code

Your installer will check the map of your area to see where the sun rises and sets. They will also use a tool called a solar pathfinder.

This is a device that helps to determine the optimum angle and orientation for your system.

It takes into account the time of year, the latitude of your location, and the surrounding landscape.

After taking all of these factors into consideration, your installer will be able to advise you on the best direction and angle for your solar panels.

Solar panel azimuth angle

The azimuth angle is the compass bearing of the sun. In the Northern Hemisphere, the azimuth angles range from 0 degrees (due North) to 180 degrees (due South).

In the Southern Hemisphere, they range from 0 degrees (due South) to 180 degrees (due North).

The azimuth angle changes throughout the day and the year, so it is important to consult with a professional to determine the best angle for your system.

Solar Panels On Both Sides Of Roof

Both sloping and flat roofs are viable options for solar panel installation.

If you have a sloping roof, it is best to install panels on both sides of the roof.

This will ensure that they are able to capture the maximum amount of sunlight possible.

FAQs

Do all solar panels need to face same direction?

In the northern hemisphere, solar panels should be placed with true south (and in the southern, true north) in mind. Because solar panels will receive direct light throughout the day, this is usually the optimum approach.

Can solar panels be installed in different directions?

Facing south is a good rule of thumb. However, with the introduction of double- technology, it’s feasible to have panels that face two directions. With tracking technology, you can get optimal tilt angle and azimuth for your location. This technology will also follow the sun throughout the day, so you can get the most out of your system, no matter what time it is.
