Other Roofing Considerations When It Comes To Solar Power

How to Install Solar Panels on a Metal Roof

Roof material is just one of the things your solar experts look at during the critical consultation stage of solar panel installation.

On top of materials, its also important to look at:

  • Age and condition
  • Angle and pitch
  • Shade and exposure to sunlight

Each of these impact the success of your solar panels. As such, they need to be carefully accounted for!

Batten Mounted Metal Shingles

These metal shingles are usually installed on a wooden lattice, called a batten, thats then attached to the roof. While putting solar on batten mounted metal shingles you should place the solar flashings between two layers of metal shingles. The shingles have to be removed to connect the mounting hardware with the roof, then the layers of shingles are put in place so that the attachment point can stick out. To prevent any leakages, a waterproof sealant is placed on all the joints.

Solar Panels Amplify The Benefits Of A Metal Roof

Most sellers wait between one and two months to receive an offer on their homes. To speed up the process, theyll upgrade finishes and features to make the property even more attractive to buyers.

A metal roof is one such selling point. Builders go for metal because its a cooling feature: it reflects light, whereas asphalt shingles absorb the suns rays and heat.

If you add solar panels, youll get an even more substantial cooling effect. Theyll soak up the suns energy while keeping the underlying roof cooler than before. Thats a win-win for you and your energy bills.

Is It Safe To Install Solar Panel Systems On A Metal Roof

Solar panels can be installed on a metal roof, but it is important to follow a few key installation guidelines in order to ensure the safety and longevity of both the solar panels and the metal roof. One of the most important things to keep in mind is that solar panels should never be mounted directly to a metal roof instead, they should be mounted to an approved solar panel metal roof mounting system. Additionally, metal roofs can be quite slippery when wet, so extra care must be taken when installing or cleaning solar panels on a metal roof.

The best choice for mounting solar panels on a metal roof is to use the same brackets that are used when mounting them on asphalt shingles. When properly installed, these can support the weight of the solar panel array without putting an excessive strain on the metal roof . The other option is to use specially designed metal mounting brackets that can be attached directly to the top surface of the metal roof. These do not put any pressure on the surface of the metal itself, so they can also be considered an acceptable choice.

Can Any Potential Leaks Cause Damage

It is rare that you will experience any leaks due to solar panel installation. In case any leaks do arise contact your installer to check whether the repair will be covered under warranty. The best way to prevent any post-installation leaks is to have a professional evaluation by an installer beforehand.

Metal Roofs And Solar Panels

One of the biggest reasons why metal roofs go great with solar panels is their durability. Since most solar panels last between 25 to 30 years, they need a roof to match. Youll be happy to know that metal roofs have a life expectancy of 50 years or higher, which means theyll outlast your panels.

Whats more, in addition to the standard photovoltaic solar panels, you can also install thin-film solar panels on metal. Now, theyre not as efficient as PV, but theyre much easier to install. Also, they dont need as much energy to make solar cells and are an excellent lower-emissions renewable energy option.

If you decide to go solar, depending on the state you live in, you can also count on some rebates or tax benefits. When you combine that with the relatively low price of metal roofs, theres almost no downside to getting solar panels.

How to Install Solar Panels to a Metal Roof

To answer this question, yes you can install solar panels on a metal roof. You can either lay down your solar panels directly on your metal roof using mounting rails or you can design custom frame to mount your solar panels to a specific angle and to face a specific direction.

The power generated from solar panels will depend on the pitch of your roof and the orientation of your roof.

The power generation of solar panels depends on the angle and direction of orientation. For maximum power generation, if you like in northern hemisphere, your solar panels should face towards south and if you live in southern hemisphere your solar panels should face towards north.

Hence, if you have a two face slope roof like north south slope or east west then one side in case of north south and two sides in case of east west will produce less power than it should.

If you have a east west roof and you directly lay down your solar panels then power generation will be sacrificed but the overall cost of installation will be less since no custom structure will be required .

But if you decide to orient your solar panels to the best direction and the best angle needed for your east-west roof, then overall power generation will increase but so will the overall cost of solar installation.

In most cases you dont have to worry about the angle of installation but the direction in which your solar panels face is important.

What Is A Roof

Solar roofing is a final product, which integrates solar panels with the roofing material suitable for either a sloped or a flat roof. The solar panels used in solar roofing are usually thin-film photovoltaic laminates. Most popular Solar PV laminates commercially used today, are the Unisolar thin-film PV panels.

Unisolar thin-film PV laminates were originally designed to fit into and be integrated with standing seam metal roof panels. Unisolar panels are 15.5 inches wide and fit perfectly into a 16 standing seam panels, and are attached or laminated with special butyl adhesive that is on the back of each Uni-solar PV panel.

However, unlike with metal roofs, solar integrators were having flat roof leak repair issues with solar systems they installed on flat commercial roofs. After they installed solar mounting racks and attached them to the roof deck, the fasteners would start leaking after a while.

Roofing manufacturers adressed this issue with different versions of flat roofing materials that integrated Unisolar PV panels one such system is IB Solar Roof. There are many types of both solar metal roofs and solar flat roofs, using solar PV panels from various manufacturers .

What Is A Rail

This type of system is based on aluminum rails that are attached in rows to your roof. The rails are secured to the roof with footings . You can see an example in the photo at the top of this article.

Rail-based solar mounting systems are strong and are the most common type in use. This popularity is advantageous because installation crews have a lot of experience with them.

Their strength can be an important factor in regions where a solar array can be subjected to strong forces, such as hurricanes. Because the rails provide rigidity, they are a good choice when high winds or heavy snow loads are a possibility.

Another benefit of rails is they provide a convenient mounting point for wiring and inverter components. Good wire management is a particularly underappreciated part of a solar installation. Poor wire management can be ugly, but can also lead to electrical problems down the road. Loose wires can flap around in the wind, eventually causing insulation to wear away, exposing the wire underneath.

On the other hand, rail-based systems may have higher costs and take longer to install than railless systems.

Heres an overview of some roofs that do and dont work with solar panels:

Metal Shingle Roofs Yes, but only if they are asphalt shingles and not galvanized steel .

Standing Seam Metal Roofs Yes, as long as they are not painted.

Corrugated Metal Panels Only if the roof is a standing seam roof and you have enough space for insulation below it .

Flat Exposed Fasteners Metal Panel Roofing Systems No because there isnt any room on top of them for wiring and you cant insulate them.

Metal Tile Roofs No because they are not flat enough.

Asphalt Shingle Roofs: As mentioned above, asphalt shingle roofs work fine as long as the metal isnt galvanized steel. In other words, if your home has a prefabricated standing seam metal roof, it is not compatible with solar panels.

Galvanized Steel Roofs: Galvanized steel roofs are composed of a thin sheet of metal that has zinc coating on the outside to protect against corrosion and rusting. These types of roofs cant be used for solar panel installation because they dont have enough space between the metal sheets for insulation and wiring.

Insulation: To hold up a solar panel, there needs to be enough room between the metal roofing surface and whatever is underneath it for a mounting bar or bracket.

Weight of one 330 watt polycrstalline solar panel is around 25 kg hence for a 5 kW system which has 16 such panels the overall weight of solar panels and mounting structure would be around 450 kg. Since the weight is distributed most roof can accommodate this much weight but it is also good to take a professionals opinion.
  • Old metal roof If you have a 10 15 year old metal roof, then chances are it wont last another 25 years, which we want since our solar panels life is well over 25 years. If your roof is old you should get it replaced with a new one before installing solar panels.
