Solar panels for metal roof

Solar panels are a great choice for a metal roof. The installation is fast and easy and the roof with panels lasts for decades. The only drawback is the performance of a system at high temperatures. Let’s look in detail at solar panels for metal roofs.

Can you put solar panels on a metal roof?

Metal roofs are often considered a good option for solar panel installations due to their durability, longevity, and compatibility with solar panel mounting systems.

There are a few important considerations when installing solar panels on a metal roof:

  1. Mounting Systems: Solar panels can be mounted on metal roofs using specialized mounting systems designed for this purpose. These mounting systems ensure that the panels are securely attached to the roof while maintaining the integrity of the roof itself. Corrugated, standing seam, and other types of metal roofs may require slightly different mounting techniques. Some types of metal roofs require penetration in order to install the panels which can affect the warranty for your roof. 
  2. Waterproofing: When a roof requires penetration in order to install solar panels, proper waterproofing is crucial to prevent water leaks. Installers need to ensure that the mounting penetrations are sealed correctly to prevent water from entering the building.
  3. Electrical Wiring: Wiring from the solar panels to the electrical system of the building needs to be carefully planned and executed. This includes ensuring that the wiring is properly protected and sealed against environmental factors.

To ensure a safe and efficient installation, it's recommended to work with professionals who have experience in both solar panel installations and metal roofing.

Do solar panels work well on a metal roof?

In general, solar panels on metal roofs work as normal but there are caveats. For one, metal roofs can get quite hot under direct sunlight. This can affect the efficiency of the solar panels if not properly managed. Some mounting systems have features that allow for airflow between the panels and the roof, helping to dissipate heat. Try to leave a 4-6 inch gap between the panels and the roof for proper air circulation. 

On the other hand, metal roofs often have a reflective surface, which can help bounce sunlight onto the solar panels from different angles, potentially enhancing their overall efficiency. This makes metal roofs potentially good even for bifacial panels.

Pros and cons of solar panels for metal roofs

Installers say that metal roof is one of the most preferable types for solar panels. Let’s look at the benefits that it offers: 

  1. Durability. Metal roofs are known for their durability and longevity. They can withstand harsh weather conditions, including heavy rain, snow, hail, and high winds. This durability ensures a stable and secure platform for solar panels. The lifespan of a metal roof often exceeds 50 years. This aligns well with the long lifespan of solar panels, creating a compatible pairing.
  2. Reflectivity and cooling effect. Metal roofs are often reflective, which can bounce sunlight onto the solar panels from various angles, potentially increasing panel efficiency. Metal roofs dissipate heat effectively, which can help maintain solar panel efficiency by preventing overheating.
  3. Compatibility and ease of installation. Many solar panel manufacturers offer mounting systems specifically designed for metal roofs, ensuring a secure and efficient installation. Metal roofs generally require minimal maintenance compared to other roofing materials, reducing the need for maintenance work around the solar panel array.

Of course, there are also negative sides to having a metal roof for solar panel installations. Here are the most important drawbacks:

  1. Cost. If you consider replacing the roof before installing solar panels, metal roofs can be more expensive upfront compared to other roofing materials. Adding up the metal roof and solar panels cost plus their installation can round up to a sizable amount.
  2. Penetration and warranties. Some types of metal roofs require penetration in order to install the panels. Installer has to make sure the roof remains waterproof. In some cases, penetration can void the warranty for your roof. 
  3. High temperatures. While metal roofs cool down quickly and dissipate heat well, they also heat up a lot under direct sunlight. Solar panels do not benefit from heat and the efficiency drops at high temperatures.
  4. Electrical Grounding. Metal roofs require proper grounding to ensure electrical safety for the solar panel system.
  5. Corrosion. Depending on the type of metal used for the roof and its coating, there can be a risk of corrosion over time, particularly in coastal or highly corrosive environments.

3 best solar panels for metal roofs

Let’s look at the top solar panels that you can put on your metal roof. We’ve picked the panels that perform especially well in hot conditions which is important when in comes to Pv installation on metal roofs. 

Panasonic 400W Solar Panel 132 Cell PNS-EVPV400HK

Evervolt solar panel by Panasonic is a top pick for hot areas. It loses less production at high temperatures which is crucial for solar systems on metal roofs. Plus, it's super efficient, working at 21.6%, while most others are around 19-20%. Panasonic gives you a warranty for 25 years and they promise that even after 25 years, it will still perform at 92% or even better.

Meyer Burger 385W Solar Panel 120 Cell MB-385-HJT120-BW-T4

Meyer Burger 385W module has 120 cells with heterojunction technology that ensures high performance at temperatures. White backsheet also contributes to lower heating of a panel. Good performance in hot places is important when you pick a solar panel for a metal roof. The panel from the European manufacturer comes with a 25-year warranty both for product and performance. The module loses no more than 2% in the first year and no more than 0.25% of production in subsequent years. 

REC 405W Solar Panel 132 Cell REC405AA Pure

Alpha Pure Black stands out as a cutting-edge solar panel in REC's lineup, hailing from Norway. With an impressive efficiency rating of 21.9%, it proudly takes its place among the most advanced solar panels available today. The sleek all-black aesthetic not only enhances its visual appeal but also seamlessly integrates with a variety of roofing styles.

Demonstrating exceptional longevity, Alpha Pure Black maintains an impressive 92% of its initial power output even after 25 years of continuous use. This remarkable durability is backed by a trio of 25-year warranties encompassing product quality, performance reliability, and labor, provided the installation is carried out by a REC-certified installer.
