Advantages of solar panels for metal roofs

Solar panels can be a great investment for your home or business. They can help you to save money on your energy bills and reduce your carbon footprint. If you have a metal roof, solar panels are a great option for you.

There are several advantages to installing solar panels on metal roofs:

  • Longevity and durability. Metal roofs are known for their longevity and durability, with lifespans of up to 50 years. This makes them an ideal substrate for solar panels, which also have a long lifespan of 25-30 years.
  • Easy installation without penetrations. Solar panels can be installed on metal roofs without penetrations, which helps to maintain the roof's integrity and prevent leaks. This is possible using specialized mounting systems that clamp onto the standing seams or corrugations of the metal roof.
  • Enhanced cooling benefits. Metal roofs are highly reflective, which helps to keep buildings cool in the summer. This can reduce the need for air conditioning, which can lead to lower energy bills.

Factors to consider when installing solar panels on metal roofs

There are a few factors to consider when installing solar panels on metal roofs:

  • Roof's age and condition. If the roof is old or in poor condition, it may need to be repaired or replaced before solar panels can be installed.
  • Roof orientation and angle for optimal sunlight exposure. Solar panels should be installed on a south-facing roof with a 30-degree tilt for optimal sunlight exposure.
  • Potential obstructions and shading factors. Trees, chimneys, and other structures can cast shadows on the roof, which can reduce the amount of sunlight that reaches the solar panels.

Types of metal roofs and their solar considerations

The three most common types of metal roofs in the UK are standing seam metal roofs, corrugated metal roofs, and metal tile roofs.

Standing seam metal roofs

Standing seam metal roof with integrated solar panels in UK homes is the most popular metal type option. It features interlocking seams that create a watertight seal, and they are very strong and durable. Solar panels can be easily installed on standing seam metal roofs using clamp-based mounting systems.

Corrugated metal roofs

Corrugated metal roofs are another popular type of metal roof, and they are often used on agricultural and industrial buildings. Mounting solar panels on corrugated roofs can be done using surface-attached mounts or ballasted systems.

Metal tile roofs

Metal tile roofs are a more aesthetic option for metal roofs, and they are often used on residential and commercial buildings. Solar panels can be installed on metal tile roofs using surface-attached mounts or ballasted systems.

Mounting systems suitable for metal roofs

There are two main types of mounting systems that can be used to install solar panels on metal roofs:

Solar panel mounting systems
Mounting typeDescription
Clamp-basedIdeal for standing seam metal roofs. They clamp on to the standing seams of the roof, without requiring any penetrations
Surface-attached Can be used on corrugated metal roofs and metal tile roofs. They are attached to the roof using screws or bolts.
Ballasted systemsUse weights to hold the solar panels in place, without requiring any penetrations.

If you're unsure which mounting system is best for your roof, it's better if you consult a professional installer. If a solar installation isn't possible or too expensive, you could discuss solar panels for a shed or a conservatory roof instead.

How are solar panels attached to a metal roof?

The installation process for solar panels on metal roofs is generally similar to the installation process for other types of roofs. However, there are a few best practices that should be followed to ensure a safe and efficient installation:

  1. Evaluating roof strength and load-bearing capacity. It is important to evaluate the roof's strength and load-bearing capacity before installing solar panels. This is especially important for older roofs, as they may not be able to support the weight of solar panels.
  2. Ensuring proper spacing and layout for efficient energy generation. Solar panels should be spaced and laid out properly to ensure efficient energy generation. The panels should be facing south and tilted at a 30-degree angle.
  3. Safety considerations and precautions. It is important to take all necessary safety precautions, such as wearing fall protection gear and working from a ladder or scaffolding.

Solar panels for metal roofs: cost

The cost of solar panels installation on metal roofs varies depending on the size of the roof and system, the type of mounting system used, and the location of the installation. 

On average, solar panels for metal roofs cost around £5,000–£14,000 fitted. You can apply for solar panel grants to reduce your initial investment or even get solar panels for your metal roof for free. The price of solar batteries is not included in the total costs.

Fact!

Let’s assume your 35 sq. m. metal roof requires around 12-16 solar panels 3.5 kW in size. Such a solar system will cost you anywhere between £5,300–£8,000 with another £900–£2,200 to have it installed.

However, solar panels can offer significant energy savings over time, and there are a number of government incentives and rebates available to help reduce the upfront cost of installation.

Solar panels for metal roofs: return on investment

The average payback period for solar panels in the UK is around 7-10 years. This means that you will start saving money on your energy bills in about 7-10 years, and the solar panels will continue to generate free electricity for many years after that.

In addition to the energy savings, solar panels can also increase the value of your property. A study by the University of Exeter found that homes with solar panels sell for an average of 10% more than homes without solar panels.

Maintenance and durability aspects

Metal roofs require very low maintenance, and so do solar panels. The main thing to do is to regularly inspect the solar panels and roof for any signs of damage or wear and tear. If you find any problems, you should contact a qualified solar installer to have them repaired.

Solar panels are made from durable materials, and they are designed to withstand the elements. However, it is important to have the solar panels installed by a qualified solar installer to ensure that they are properly secured and that the roof is not damaged during installation.

Conclusion

Solar panels can be a great way to reduce your energy bills and carbon footprint, and they are well-suited for installation on metal roofs. Metal roofs are durable and low-maintenance, and they can be easily installed with specialized mounting systems.

By investing in the right solar panels for metal roofs, you can enjoy the benefits of reliable and sustainable electricity for many years to come. With proper research and installation, you can contribute to a cleaner, greener world. 

If you are considering installing solar panels on your metal roof, there are a few things you should do:
