Silicone sealant for solar panels plays a major part in keeping solar PV performing effectively.
Although the process of manufacturing solar modules seems fairly straightforward, their effectiveness and lifespan are determined by the performance of their components, which, when coordinated efficiently, is expected to lead to solar modules lasting 25 years or longer.
Photovoltaic panels must be efficient and durable enough to be able to withstand adverse weather conditions for at least 20 years. These solar modules ought to be assembled & put together with high-quality components in order to meet the ever-growing market demands in order to guarantee effective operation and safety.
Components of Solar Photovoltaic Modules
In general, solar photovoltaic modules are made up of seven components, including tempered glass, solar cells, aluminium alloy frames, EVA film, back sheets, connection boxes, and solar sealant.
The main parts of the solar photovoltaic power generation system among them are solar cells. Silicone sealant for solar panels plays an essential role in safeguarding those precision pieces since solar cells are thin, brittle, and easily oxidised.
For a solar panel to perform at its best for a long period, solar sealants are essential. These solar photovoltaic modules are majorly installed outside- for example, on the roof of a building.
Hence, these photovoltaic modules must be able to adjust to varied climatic conditions, including high temperatures, high humidity, high and low temperatures, intense UV rays, ozone, wind, and rain.
So, in this blog, we'll take a closer look at solar sealant, a material that may remain overlooked but is nonetheless essential to the reliable and long-term operation of solar modules.
Why are silicone sealants used for Solar PV Modules?
Synthetic chemicals known as silicones (polysiloxanes) are polymers composed of siloxane repeating units. Typically heat-resistant, silicone comes in a liquid or rubber form.
Silicones have several uses, but they are majorly utilised in adhesives, sealants, lubricants, and electrical and thermal insulation.
Since it has such strong adhesion, impact resistance, and superior mechanical qualities, silicone is frequently employed as a sealant.
During the manufacturing of solar panels, weatherproof silicone sealants are used to maintain the solar modules' perfect structure and weatherproof them.
Advantages of Using Silicone as Edge Sealant
The PV module manufacturing industry is constantly seeking ways to reduce production costs without compromising component reliability or efficiency.
Sealants can be used for a range of purposes, including securing frames, joining junction boxes, and sealing ribbons. PV modules are shielded from the effects of the outside world by silicone sealants, which maintain long-term durability.
There are several key benefits of using silicone sealants for solar panels such as their dependability, exceptional fluidity and gap-filling properties, outstanding thermal conductivity, good dielectric characteristics, flame retardancy, strong adhesion, and good resistance to environmental effects.
Additionally, silicone sealant for solar panels can offer a dependable and strong bond in applications that require flexibility or resistance to high temperatures and moisture.
Things you need to know about PV/solar silicone sealants before installation
Understanding the materials to be bonded
In order to identify the best adhesive for your project, you need to understand the materials to be bonded, or substrates, as well as the roof and solar mounting systems.
Silicone Sealant for waterproofing solar PV roof
Waterproofing the roof is arguably the primary function of silicone sealants, which is essential for guaranteeing a tidy installation and a sturdy bond.
Form a thick bond line to hold off the water that is at least 2 to 3 mm thick to provide a robust hold. You must make sure the sealant line isn't too thick because it could lead to cohesion problems.
It is also important to consider the environment's temperature when installing. In order to ensure that the sealant cures properly, you should apply it at room temperature because freezing temperatures can encourage condensation, and high temperatures can interfere with it.
Although some high-quality silicone sealants, such as Bondzil weatherproof sealants, are suitable for temperatures ranging from -20 to 180 degrees Celsius.
As one of the best silicone sealant manufacturers in India, Bondzil is known for its uncompromising quality and reliable performance.
Extreme conditions and temperatures
No matter where in the world solar modules are installed, they will be subject to challenging weather and system circumstances.
Understanding different weather patterns and project conditions are crucial for effective installations.
There are many circumstances to take into consideration, however, the following are a few to bear in mind:
Project Conditions
The cure may be impacted by the local weather. Although heat plays a part, the main factor influencing how quickly a cure takes place is humidity.
Tidiness
Better adherence is the result of greater cleanliness. Remember that rooftops might be dusty, so try to have a tidy spotless, dry surface.
Load carrying capacity
Although the main load-bearing element will be bolts and fasteners, adhesives and sealants have a place in this. They may also assist in damping wind loads on the equipment.
