Wall Mount Solar Panels: An Eco-Friendly Solution of Renewable Energy
The future is becoming greener all around the world. One of the key constituents of this transition is the widespread adoption of renewable energy sources. Solar panels mounted on walls are emerging as one of the revolutionary and realistic options in the realm of clean energy. Solar panels can now be installed straight onto vertical walls, turning mere building surfaces into electric powerhouses. This smart innovation not only addresses space limitation but also maximizes solar exposure at certain times of the day, making the overall efficiency higher. Wall mount solar panels are best suited for residential and commercial use. With the increasing demand of solar, technological advancements making it more efficient and cost effective everyday.
Let’s explore the working of wall mounted solar panels, the benefits of installing solar panels on walls and how they are different from rooftop solar.
How to mount solar panels on walls?
It is vital to determine the walls of your home where you are desiring to install the PV modules. Your walls must be strong enough to handle the weight of solar panels on it. Wall mount systems require a special hardware kit. The problem with wall mount systems is that they have to work against gravity to stay in place. So, their installation requires a lot of extra material which includes extra brackets, nuts, bolts, washers, and of course extra labor as well. The additional grip offered by these wall-mounting brackets prevents the solar panels from dropping during severe weather.
What are the best walls to mount your solar PV?
Mounting brackets usually require two screws which get attached to either side of solar panel frames. Afterward screws, nuts, bolts, and washers attach the brackets to the wall. You have to make sure that the brackets are leveled and securely attached to the wall. These mounting brackets are quite flexible which helps to achieve the optimal angle for power production.
Wall-mounted systems require high slopes and great angles with sun rays which eventually decreases the overall efficiency of solar power production in solar PV modules. Under such circumstances the placement of solar panel systems becomes crucial. Therefore, to attain maximum output out of wall mount systems their placement should take place on the south-facing walls of your house.
Is there any difference between rooftop and wall-mounted solar systems power production?
Rooftop and ground mount solar PV modules, especially on the best roof for solar panels, produce more electricity as compared to wall mounts. This is due to two primary reasons: first, wall-mounted solar panels face a steeper slope, and second, they are installed closer to the ground. In the winter season, the power production of wall mount systems is at its peak, which happens because the sun starts setting lower in the sky. This causes the sun’s rays’ angle to perfectly align with the slope of the wall mount solar panels. But in summer when the sun shines high in the sky, solar on roof systems, and ground-mount solar systems generate more electrical power than wall-mount systems.
What are the advantages of wall mount solar panels?
Comparing wall-mounted solar panels to rooftop or ground-mounted systems, we notice a number of benefits. Wall-mount solar panels can reduce your electricity bill and produce renewable energy from the unused space in your home. Let’s look at some advantages of vertical solar panels or wall-mount solar panels.
1. Easy installation process and maintenance:
Wall-mount solar panels are easy to install and maintain. Unlike rooftop solar PV modules, scaling, and installation does not require climbing the roof and drilling holes into the rooftop of your home which sometimes can cause water leakage through the rooftop. Additionally, wall-mount panels also provide a better visual representation. Also, the maintenance of the wall mount system is comparatively easier.
2. Convenient cleaning:
Vertical solar panels are set up on your home’s side walls. So, debris, dust, and snow do not build up on them. And when there is build up, it is easily washed up by the rainwater. Additionally, and due to their parallel placement, leaf buildup does not affect wall-mounted panels. This makes cleaning wall-mounted panels much easier than cleaning rooftop solar PV modules.
3. Aesthetically pleasing:
Solar panels mounted on side walls are visually pleasing and give the house a more contemporary feel. Panels which come in various hues and finishes are a great alternative for homeowners who wish to enhance the overall appeal of their property.
Are there any drawbacks to wall mount solar panels?
Since wall-mounted solar PV modules are parallel to your home walls, they require special mounting brackets which can cause the initial installation cost of solar panels to jack up. Another drawback of mountable solar panels is that if you install them on the west side of your home’s walls, they are not going to work as efficiently as rooftop systems. This happens because the sun’s direction is usually south or southwest.
Moreover, if you still install mountable solar panels on the south side of your home, their efficiency will still be less than rooftop and ground-mount solar panels. This happens because the angle of sun rays will not be able to hit the wall mount panels properly. This leads us to another consideration, such as finding the best roof and solar system setup to maximize efficiency. The slope of wall mount solar panels is quite higher than usual solar systems. Which makes it difficult for sunlight to reach solar panels. These are some of the main reasons why the efficiency of wall mount panels is low as compared to rooftop or ground mount panels.
For what type of homes are wall mount solar panels a smart investment?
Wall-mount solar panels are a smart investment for those who want to utilize the extra space along the side of their home. They can also solve the problem of shaded rooftops. Wall mount panels are best for your home if your home walls are southward facing. They are also suitable for your home if your hometown faces a prolonged winter season.
In conclusion, installing wall mount solar panels is a great investment since they reduce electricity costs, shrink carbon footprints, and improve energy efficiency. Wall mount solar panels are now more durable, efficient, and accessible than ever before.
