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.
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:
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.
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.
Installers say that metal roof is one of the most preferable types for solar panels. Let’s look at the benefits that it offers:
Of course, there are also negative sides to having a metal roof for solar panel installations. Here are the most important drawbacks:
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.
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 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.
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.
