As the world seeks to reduce its carbon footprint, solar power is becoming increasingly popular. Photovoltaic (PV) roofs, in particular, are gaining traction due to their ability to generate electricity while also protecting the building from the elements. However, there is one issue that can impact the efficiency of PV roofs: reflection. That's where high-reflective POE film comes in. In this article, we'll explore the benefits of using high-reflective POE film on PV roofs and how it can enhance their performance.
Different from EVA film, which is made by the EVA extrusion process, high-reflective POE film is a specially designed film that can be applied to the surface of a PV roof. This film is made from a type of plastic called polyolefin elastomer (POE) that is highly reflective. When sunlight hits the surface of the film, instead of being absorbed or transmitted, it is reflected back into the atmosphere.
By using high-reflective POE film on a PV roof, the amount of reflection can be greatly reduced. This means that more sunlight is absorbed by the PV cells, resulting in a higher efficiency for the PV roof. In fact, studies have shown that the use of high-reflective POE film can increase the efficiency of a PV roof by up to 5%.
There are several benefits to using high-reflective POE film made by the film extruder on a PV roof. Let's take a look at some of the most significant benefits.
Increased Efficiency
As we've already mentioned, using high-reflective POE film can increase the efficiency of a PV roof by up to 5%. This means that more sunlight is absorbed by the PV cells, resulting in a higher output of electricity. This is particularly beneficial for buildings that rely on solar power as their primary source of electricity.
Reduced Heat Build-Up
Another benefit of using high-reflective POE film is that it can reduce heat build-up on the roof. When sunlight hits a roof, it can cause the temperature to rise, which can lead to heat build-up inside the building. This can make the building uncomfortable for occupants, and it can also put a strain on air conditioning systems. By reflecting more sunlight back into the atmosphere, high-reflective POE film can help to reduce heat build-up on the roof.
Longer Lifespan
High-reflective POE film can also help to extend the lifespan of a PV roof. When sunlight is reflected back into the atmosphere, it reduces the amount of wear and tear on the roof. This means that the roof will last longer and require less maintenance over its lifespan.
Environmentally Friendly
Finally, using high-reflective POE film is an environmentally friendly option. High-reflective POE film can reflect up to 80% of solar energy, reducing the amount of heat entering a building. This can help to reduce the need for air conditioning and lower energy costs.
