Can You Put Solar Panels On A Metal Roof?
More than ever, consumers are dedicated to environmental sustainability. The Inflation Reduction Act is expected to lead to solar installations to rise by 40% between 2023 and 2027. (IRA). There are further incentives for homeowners to put in solar panels if they haven’t already, like energy savings and a federal solar tax credit. You must first consider the mechanics of how the solar panels will affect your roof before you can do that.
We at Western States Metal Roofing, manufacturers of metal roofing panels, are commonly questioned if solar panels may be placed on a metal roof. Yes, you can install solar panels on a metal roof, to give you the quick answer. But, there are a few things you need to be informed of first.
Solar Panels on Metal Roof
Undoubtedly, solar panels and metal roofs are a great match, but solar panels can be placed on the bulk of roof types. In comparison to the lifespan of your solar panel system, metal roofs have a lifespan of 40 to 70 years. As a consequence, you won’t have to take your solar panels off to finish your roof repair. In fact, installing solar panels on a metal roof without roof penetrations is frequently possible, which is the perfect condition.
The Benefits of Solar Panels
Lock in electricity rate
Large tax rebate
Increased home value
Good for the environment
Solar Panels on A Standing Seam Metal Roof
Solar panels with metal roofs are very compatible. These ought to be used with standing seam panels, as we advise. This eliminates having to make roof holes when using these roofing panels to secure the solar panels.
A solar mounting system may be connected to the vertical ribs at the panel borders of a standing seam panel without having to make any penetrations. A roof’s weather tightness can be affected by any surface penetrations, leaving the roof accessible to leaking. One of the most solar panel suitable roofs in general, standing seam is not just the most compatible among metal roofing panels. Solar panels may still be installed with mounting brackets on corrugated metal roofs. But, using fasteners that will pierce the corrugated metal panels, the brackets will be fixed to the panels directly.
Solar Mounting Systems for Metal Roofs
A solar mounting system is an instrument which lets you put solar panels on your roof without having to make any modifications to it. You won’t have to be concerned about invalidating the roof’s manufacturer’s warranty or causing the roofing system any long term harm if you use a solar mounting system. Each solar mounting system is simple to retrofit onto your metal roof, whether it is old or new.
Solar Mounting System Cost
10–25% of the total cost of your solar system is made up by the solar mounting system.
Choose A Lighter Colour Metal Roof For More Energy Efficiency
In addition to solar panels, the colour of your new metal roof, if you’re installing one before your solar system, can assist you enhance energy efficiency. Lighter colours will save the most energy (beige, tan, white, light gray). Lighter colours are better at reflecting the heat of the sun while dark hues, like black, absorb more heat. Dark hues only reflect 5 to 20% of sunlight, but light colours can reflect anywhere between 55 and 90% of it.
Light roof colours help prevent the roof from being exposed to extreme heat, which saves your AC system from operating as often and keeps your energy down costs.
A Durable and Strong Mounting System
Drilling holes right through the roof is used to connect solar panels to an asphalt shingle roof. These holes in the roof’s surface have the potential to cause leakage and other issues. On the other side, solar panels may be installed on standing seam metal roofs without compromising the integrity of the roof or nullifying the roof’s guarantee thanks to a zero-penetration clamping mechanism.
Moreover, metal offers a very sturdy foundation that can withstand the weight of large solar systems, lowering the risk of roofing failure.
Which solar panels are most effective with metal roofs?
Thin-film solar laminates
When it comes to quick and simple installation, they are the finest. Without drilling or cutting the metal roofs, they may be placed. Furthermore, due to their clean, slim design, they have a pleasing look.
Crystalline panels
They generate a significant amount of electricity each day and offer a unique mounting mechanism for both metal and shingle roofs. Even if these are larger than thin-film panels, you can be sure that they will serve you for up to 25 years before the productivity may begin to gradually decline.
Are there any future plans to put solar panels on metal roofs?
To hire the most suitable installers for the job, you should have a checklist ready. Even if you have some knowledge of the subject, DIY (Do It Yourself) is not recommended. Later on, issues might arise from the procedure. Check that the contractor has completed the list now:
- Possesses enough experience with solar installation projects.
- Possesses the skills and knowledge necessary to handle metal roof installation jobs.
- Has updated knowledge of the most latest events and technologies in solar panels
- Offer immediate assistance for reasonable costs
- Is skilled in managing installation jobs in a variety of circumstances
- Has the ability to accurately explain the procedures, allay your concerns, and answer questions.
Installing Solar Panels on a Metal Roof
Installing solar panels on a metal roof can be a great way to harness renewable energy and reduce your carbon footprint. Here are some things to consider when installing solar panels on a metal roof:
Check your roof’s condition
Make sure your metal roof is in good condition and can support the weight of the solar panels. If the roof is damaged or corroded, it may need to be repaired or replaced before installing the solar panels.
Choose the right mounting system
There are different types of mounting systems available for solar panels, such as ballasted, penetrating, and adhesive systems. Make sure to choose the one that is suitable for your metal roof type and structure.
Consider the orientation and tilt angle
The orientation and tilt angle of the solar panels can affect their efficiency and energy output. South-facing roofs generally receive the most sunlight, but east or west-facing roofs can also work well depending on your location. The optimal tilt angle for solar panels is typically between 10 and 40 degrees, depending on your latitude.
Ensure proper sealing
Proper sealing is crucial to prevent water from leaking into your home. The mounting system should be properly sealed around each penetration point to prevent any water damage.
Hire a professional installer
Solar panel installation can be complex, and it is recommended to hire a professional installer with experience in installing solar panels on metal roofs. They can ensure that the installation is done safely, correctly, and according to local building codes.
Overall, installing solar panels to a metal roof may be a great way to lower your carbon footprint and save money on utility bills. With the right planning and installation, you can enjoy the benefits of solar energy for years to come.
F.A.Q.
Is it OK to put solar panels on a metal roof?
Yes! Due to its strength, which readily accommodates the weight of the solar array, panels, mounting racks, and related gear, metal roofs are considered the most suitable roofing material for compatibility with solar panels and are a top choice among roofing contractors and solar installers.
Why are there no solar panels on metal roofs?
Vertical ribs at the panel edges of standing seam panels allow a solar mounting system to be attached here without the need for penetrations. On a standing seam metal roof, solar panels. A roof’s weather tightness can be weakened by any surface penetrations, making the roof susceptible to leaking.
What metal roof is best for solar panels?
Metal standing seam
One of the best roofing materials for the installation of solar panels is standing seam metal. Large, protruding seams in the metal allow for simple panel array attachment resulting in a less costly installation. Also, it’s not necessary to drill holes in the roof.
How are solar panels fixed to a metal roof?
Solar panels cannot be placed onto a corrugated metal roof without drilling holes; every care is taken to keep them watertight. It needs a unique mounting setup that takes use of straddle block brackets.
Which metal roof colour works best with solar panels?
Bright shades will save the most energy (beige, tan, white, light grey). Lighter colours are better at reflecting the heat of the sun while dark hues, like black, absorb more heat.
