Solar power generation reflective film

What is reflectech® mirror film?

ReflecTech® Mirror Film is a highly reflective, flexible polymer film for concentrating solar energy applications. Developed specifically for concentrating solar power applications, this reflective film is used in many solar concentrators that leverage this polymer film’s low cost, light weight, and flexible properties.

What is reflective polymer film technology?

With performance at the level of silvered glass mirrors, reflective polymer film technology offers This polymer mirror film has a solar-weighted hemispherical reflectance of 94% and a specular reflectance of 94% at a 25-mrad (1.4°) full acceptance angle at 660 nm (Table 1).

Are solar reflectors a good choice for a concentrated solar collector?

High reflective and durable mirrors are required for the viability of a concentrated solar collector. This paper is aimed to present the up to date progress in the solar reflector material and their performance testing. Thick glass mirrors with a protective coating against the weathering have made the place in the solar thermal power plant.

Which material should be used for a solar reflector?

The glass mirror and aluminium are the main candidate material for the solar reflector. Reflectivity, durability and cost are the major parameters considered during the performance testing of the reflector material. In this article, studies on reflective surface preparation techniques and their durability analysis are also discussed.

What is reflectech® film?

ReflecTech® film is easily manufactured at high volume in rolls containing up to several hundred meters of material. This allows for greater production efficiency and design flexibility in reflector aperture widths. The polymer film has an adhesive backing to enable easy application to a rigid substrate material such as aluminum.

Are silver-coated glass and silver-polymer film a good reflector material?

Silver-coated glass and silvered-polymer film observed to be effective than other tested reflector materials. Sulphur dioxide is the major component, which causes a strong reduction in the reflectivity of the mirror when exposed to the acid rain atmosphere.
