Solar power is a clean and renewable energy source. The demand for solar power has been growing as it is an affordable, safe and sustainable way to generate electricity. Solar panels are now being installed on rooftops all over the world. Installing a solar panel roof mount using glue isn’t difficult, but there are a few things you should consider before you start the installation, so make sure you read all the way to the end.
3 steps to gluing your solar panel to your roof
The following tips are general guidelines for when you need to glue solar panel to roof. For the specific, step-by-step process, you need to consult the instruction manual for the glue that you’ll be using (the 3M is especially popular, and by following the link, you can see an example of an instruction manual that has been made for solar panel glue).
Here are the general guidelines:
- Use a rubber roof coating to help solar panels adhere to your roof.
- Choose the right type of solar panel for the roof you have. If you have a metal roof, choose metal solar panels. If you have asphalt shingles, choose an asphalt solar panel.
- Install the panels in an orientation that will get them the most exposure to direct sunlight – preferably south or southwest facing roofs for Northern hemisphere locations, or north or northwest facing roofs for Southern hemisphere locations.
Is glue strong enough to mount a solar panel to your roof?
The strength of the adhesive is critical to the long-term performance of solar panels. Glue can be used to mount solar panels on roofs. However, there are many factors that affect the ability of a glue to have an effective bond, including the type of roof, substrate, and the adhesive’s viscosity.
To glue solar panel to roof is usually possible for houses (unless you live in an area that is oft-stricken by tempests), but glue is not strong enough to mount a solar panel onto the top of your vehicle. If you were to use glue, the solar panel would fall off after some time. This is because glue does not provide much structural support and it would be difficult to apply the needed pressure that would keep the panel in place.
How long does glue for solar panels last?
There are several factors that affect the life of the glue on solar panels. The main factor is temperature. The hotter it gets, the faster the adhesive will deteriorate. Moisture can also cause problems for solar panel glue.
The type of glue used on solar panels also has an impact on how long they last. For example, epoxy adhesives are more suitable for humid environments than polyurethanes.
Are there other better installation methods than to glue solar panel to roof?
That depends on where you’re going to mount a solar panel. The best way to mount a solar panel on the top of your car, for example, is with bolts and brackets. This will ensure that the panel stays in place for as long as you need it there.
