Wondering if you can put solar panels on your metal roof? The simple answer is yes, you definitely can. Metal roofs are actually great for solar panels.

In this article, we'll talk about why metal roofs work well with solar panels and what you need to think about before adding them to your roof. We'll focus on the best types of solar panels for metal roofs, the ones we at Astrawatt Solar recommend and use.

Understanding Metal Roofs and Solar Panel Compatibility

Types of Metal Roofs

Metal roofs come in different styles, and it's good to know which kind you have when thinking about solar panels.

Standing Seam Metal Roofs: These have raised seams where the panels join together. They're perfect for solar panels because we can attach them without drilling holes. This means there's less chance of leaks and it's easier to put them up.

Corrugated Metal Roofs: These are the ones with the wavy pattern. They're also good for solar panels, but the installation is a bit different. We usually have to drill holes to secure the panels, but don't worry – we make sure it's all sealed up and waterproof.

Recommended Types of PV Panels

At Astrawatt Solar, we use standard photovoltaic (PV) panels. Here's why they're a good choice:

Efficiency and Reliability: PV panels are known for turning a lot of sunlight into electricity and they last a long time. This makes them a smart choice for your metal roof.

Suitability for Metal Roofs: These panels fit well on different types of metal roofs. Whether you have standing seam or corrugated metal, we can work with it.

Advantages of Installing Solar Panels on Metal Roofs

Durability and Longevity

Metal roofs and solar panels are both built to last. A metal roof can last up to 50 years, which is about the same as the lifespan of solar panels. This means you won't have to worry about replacing your roof or panels anytime soon. It's a long-term investment that saves you money and hassle in the long run.

Increased Energy Efficiency

Metal roofs are great at reflecting sunlight. This helps keep your house cooler and can cut down on air conditioning costs. When you add solar panels, you get the bonus of generating your own electricity. This combination can significantly lower your energy bills.

Environmental Benefits

Choosing solar panels for your metal roof is good for the planet. Metal roofs often contain recycled materials and are fully recyclable. Solar panels produce clean, renewable energy. Together, they reduce your carbon footprint and help protect the environment.

Metal roofs and solar panels are a smart match. They're durable, energy-efficient, and eco-friendly. If you have a metal roof, adding solar panels is a great way to save money and do something good for the planet.

Considerations Before Installing Solar Panels

Before you put solar panels on your metal roof, there are a few things to think about to make sure it's the right choice for your home.

Roof Assessment

First, look at the condition of your metal roof. It should be in good shape without any damage or rust. Also, check if the roof is strong enough to hold the solar panels. Most metal roofs are, but it's always good to be sure.

Roof Orientation

The direction your roof faces matters for solar panels. South-facing roofs are best because they get the most sun. But, east and west-facing roofs can work well too. The key is to get as much sunlight as possible.


If there are tall trees or buildings casting shadows on your roof, that could mean less sunlight for your solar panels. Fewer shadows mean more solar energy.

Roof Material Compatibility

Not all solar panels work with every metal roof. We'll make sure the panels we use match your roof type. For standing seam roofs, we use clamps that attach easily. For corrugated roofs, we have other secure methods.

Roof Warranty

Check your roof's warranty. Some warranties might have conditions about adding things like solar panels. We'll help make sure installing solar panels doesn't affect your roof's warranty.

Installation Method

We take care to install your solar panels in a way that keeps your roof safe. For standing seam metal roofs, we use non-penetrating clamps. For corrugated roofs, we make sure any holes are sealed properly.

Thinking about these things before you start will help make your solar panel installation smooth and successful. With the right planning, solar panels can be a great addition to your metal roof.

Installation Process for Solar Panels on Metal Roofs

When it comes to installing solar panels on your metal roof, Astrawatt Solar follows a specific process to ensure everything is done safely and effectively.

Mounting Systems

Standing Seam Metal Roofs: For these types of roofs, we use a special clamp attachment. This method is great because it doesn't require any drilling. That means there's no risk of leaks and it's quicker to install.

Corrugated Metal Roofs: These roofs are a bit different. We usually need to drill holes to secure the panels. But we're very careful to seal everything up properly. This keeps your roof watertight, just like it was before.
