Can You Put Solar Panels on a Garage Roof?

It’s no secret that solar panels are more efficient on roofs than on windows or on the ground. However, we cannot always put them on the top of the house, but they’re better exposed to direct or indirect sunlight.

And there are many things you can do in your garage, both monetary and otherwise. This is why it makes sense to install solar panels to power the activities in this room.

So, can you put solar panels on a garage roof? Well, the direct answer is yes, but the surface must be suitable for the installations and other processes that would occur.

Can Solar Panels Be Installed On a Garage Roof?

Solar panels need access to sunlight for maximum output. That’s why you’ll find most panels on the house’s roof. But again, not everyone gets that lucky.

If you have a garage roof with a nice and tidy surface, it may be suitable for installing solar panels. This can be effective for increasing the utility of the garage, and you can even turn it into an off-grid solar power garage.

If the roof structure is appropriate, strong, and devoid of obstructions, why not? If these qualities are present in your garage roof, you can install solar panels. The slope of the roof must also be suitable.

You also need to ask some questions, such as the last time the roof was replaced. If it’s been more than three decades, then the weight of the solar panels may be too much to bear.

The shape of the roof also determines the number of panels you’re using. But it’s better if it faces the south because that’s where sunlight is abundant. But if it’s tilted towards the north, you can also work with it.

Furthermore, solar panels are expensive and tricky to remove once they’ve been installed on the roof. So, if you have plans to remodel your garage anytime soon, do it before mounting the solar panels.

Is Your Garage Roof Suitable For Solar Panels?

Moreover, it’s important to remember that a garage roof and a house’s roof are built differently. So, you must consider some factors before installing the solar panels there.

1. Roof Orientation

It’s no secret that sunlight is more accessible from the south. So, if your garage roof is designed that way, it’s suitable for installing solar panels.

On the other hand, a north-oriented roof also works, but it may not be as effective. But again, some roofs are built in neither inclination, which leaves you in a tight spot indeed.

Another problem arises with the inability to determine where the roof is inclined. In that case, consider getting a compass.

2. Elevation

The angle of elevation is also critical in the grand scheme. The roof must be inclined at 40 degrees for full access to sunlight. However, twenty is accepted for the summer, and 45 degrees for the spring.

Furthermore, a flat or low-pitched roof isn’t a significant concern. But you can opt for a solar system that automatically inclines its panels towards the sun.

3. Shade

Solar panels need adequate sunlight for maximum performance. That’s why shade is one of the most important factors to consider when installing the system. Choose an area where adequate sunlight falls on the surface.

And if you’re one of the property owners who chose to erect their garage in the backyard, you must pay more attention to shade. There should be nothing blocking sunlight from the panels. Remove tree branches and other objects from view.

4. The Strength of The Roof

If your roof isn’t strong enough, it may be unable to withstand the installation process. You may not be in the proper position to determine the garage roof’s suitability, so call professionals to inspect it.

Although DIY projects are becoming even more simplified, there are some things that you should leave to a technician. For instance, the inspection of the garage roof – you may be less than qualified to determine if the structure is sturdy enough.

Can I Power My Garage With Solar Panels?

Do you own a detached garage that sometimes doubles as a small workshop? This isn’t uncommon, but there’s a way to reduce your excessive electricity bills. Power tools drain energy, and there are many solar sources you can turn to.

And installing it on a detached roof is more manageable than it used to be.

So, can you power your garage with solar panels? Well, the simple answer is yes. It’s a great way to introduce sustainable energy to a modern home. Note that the garage won’t be the only recipient of solar energy – you can also install the panels on this structure and tap into its benefits at home.

Alternatively, you’re allowed to move all appliances that consume the most electricity to your garage. That way, your regular electricity bills will be significantly reduced.

But that’s not all. Powering your garage with solar panels means the door will open automatically, even when there’s an outage.

And you can set up a vehicle battery-charging system with the electricity generated. Additionally, you can also connect the lights to the solar system.

Alternative Places Where Solar Panels Can Be Placed

The typical property owner installs their solar panels on the roof of the main building. This practice is common because it efficiently exposes the solar cells to more sunlight, which boosts the solar system’s performance.

But again, there are rules to installing solar panels anywhere, and the failure to adhere may cost you.

Following those rules, you can explore options other than the roof. For instance, the ground is also great to put your solar panels on. Provided there’s no shade obstructing it; it’ll work just as efficiently. If these options aren’t available, consider installing them close to walls.

Parking lots and exterior corridors are also great places to consider.

Now, you shouldn’t only be concerned about where to place the solar panels but also the ideal angle and elevation to use. People favor rooftops for solar panel installation because it provides complete access to light.

However, if you do not have that luxury, the other methods also boost the efficiency of the solar cells.

It’s not uncommon for property owners to install their solar panels on the roof, but even that may be unsuitable for one reason or the other. To be safe, we recommend talking to a technician before making any major decision regarding installing the solar panels.

They’ll be in a better position to tell you if your roof has been installed in a manner that’ll be efficient for the solar cells. This decision is significant enough to determine how much power your solar home receives.

Essentially, you can install your solar panels anywhere. But the area must be free from obstructions to the surface.

Do Solar Panels Cause Roof Leaks?

Naturally, solar panels should not cause roof leaks. You see, the solar system has been designed for easy installation, and some brands even make products that you can do yourself.

But again, it’s important to note that roofs are made from many different materials, making some structures less compatible with installing solar panels. And some conditions also expose you to leaky roof conditions, such as aging shingles.

If the roof hasn’t been changed in more than thirty years, it may not be a good idea to install solar panels. The materials will likely be more susceptible to wear and tear, and that’s even if it hasn’t already started rotting internally.

Now, imagine the weight of solar panels and their tempered glass – it may be catastrophic. And even if it isn’t, expect some areas of your roof to feel the impact of the extra weight, which sometimes causes a leaking roof.

If the flashing is also deteriorating, it becomes unable to work efficiently and may allow water into your ceiling.

A flawed installation process will almost certainly cause a leaky roof. That’s why it’s advisable to employ professionals; they always follow a safe procedure that ensures the structure of your home doesn’t get affected.

On the other hand, if the person doesn’t take the correct measurements and ensure a tight fit, there may be damage later in the future.

You can easily prevent your solar panels from causing roof leaks by hiring the right person for the job. And if you have an old roof, you can simply replace areas that’ll bear the weight of the tempered glass.

Can You Put Solar Panels On a Rubber Roof?

Solar technology has been designed to be widely accommodating, which means you can install it on almost any roof type, including rubber. There’s no particular roof type that’s ideal for solar panels.

But lag bolts are better than VHB tape because the glue may become weaker.

Benefits of Putting Solar Panels On a Garage Roof

People who use solar power as their alternative electricity source are fast increasing. And rightly so, because the energy from the sun is more efficient, cleaner, and ultimately better for the environment.

The ecosystem has unarguably suffered some untold damage, which is why solar power exists to undo our carbon impact. There are several benefits of putting solar panels on a garage roof, and they are:

1. Lower Bills

Solar energy is a sure-fire way to halve your electricity bills. And even if you’re not entirely transitioned into solar power, your house will likely use the electricity stored in the inverter before it switches to electricity for the company.

But again, many people have thought about a solution to this problem, and that’s connecting heavy appliances and equipment to the solar system. So, these devices consume a significant portion of their energy from solar power before switching to electricity provided by your utility company.

2. It Increases The Value of Your Property

Solar power means uninterrupted electricity, especially when you have a capable inverter. This means people who rent your property will spend less on utility, inherently increasing the value you’re offering.

And you may also decide to sell your home with solar panels installed. Look for a buy that’ll appreciate the services it provides.

3. It’s Low Maintenance

You need to clean your solar panels now and then, but that’s essentially all the maintenance you need.

4. Lower Carbon Footprint

Finally, you can invest in solar panels to reduce your carbon footprints. It’s a renewable energy source that doesn’t release poisonous substances into the environment, making it the number one choice for sustainable energy.


Solar panels employ a versatile technology that ensures everyone can access sustainable energy. What’s more, many affordable options are easily accessible by all.

And if your house roof is unideal for personal or logical reasons, there’s still hope for you. The garage roof is often suitable for solar panels, and we’ve explored the factors that can help you determine that.
