Alubond Solar Collector Mirror

Alubond Solar Collector Mirror (ASCM) is a result of pioneering research in metal composite technology. Alubond USA brings this innovation to CSP and CPV systems that is superior to the conventional glass mirror technology being currently used which is heavy, expensive and highly breakable.

The ASCM is a unique worldwide patented composite panel, sandwiching a high durable exterior grade core between two layers of metal skin. the ASCM is light weight, features phenomenal flatness which retains its shape and comes with low maintenance. This translates in to easier handling, packaging and shipping.

The ASCM requires minimum support structure assembly thereby maximizing ease of installation and fabrication. This results in cost saving in assembly of solar units.

ASCM is designed to provide high reflectivity along with rigidity to take and retain parabolic shapes. ASCM’s have high reflectance ranging from 91% to 95%, strong weather and corrosion resistance, longevity and adhesion properties that provide an advanced alternative to the glass mirror technology.


Alubond Solar Collector Mirrors (ASCM) are the new generation multilayered metal and plastic composite panels.


  • Parabolic Trough System.
  • Heliostat System.
  • Fresnel CSP Systems.
  • CSP Dish Systems.


  • Unbreakable.
  • Mass Production.
  • On Site Curvature.

Alubond Solar Collector Mirror vs Glass Mirror


Southwest Research Institute Certification

The Alubond Solar Collector Panel was submitted to the Southwest Research Institute for certification as a solar panel material and was labeled as simple “B” for evaluation of its reflectance (%R) properties of its anodized mirror surface. Below are the findings:

Reflectance analysis of sample “B” consisted of the following determinations:

  • Total reflectance.
  • Specular reflectance.
  • Visible reflectance.
  • Solar reflectance.

Curve Smoothed Spectra: The total, specular, visible, and solar reflectance spectrums were curve smoothed using a IS- point moving average.

Figure 1 shows the total reflectance spectrum after curve smoothing.

Figure 2. Shows the sample “B” corrected specular reflectance spectrum after curve smoothing.

The visible reflectance spectrum of Sample “B” taken from the corrected total reflectance spectrum after curve smoothing is shown in Figure 2.
Figure3. shows the total reflectance spectrum for Sample “B” when using the uncertified mirror as the background scan.

The 50 selected ordinate solar reflectance spectrum after spectral on correction is shown in Figure 4.

The calculated direct normal irradiance solar reflectance from the integral equation is 91.4 %R
