    Test results to date for several candidate solar reflector materials will be presented. These include the optical durability of thin glass, thick glass, aluminized reflectors, front-surface mirrors, and silvered polymer mirrors. The development, performance, and durability of these materials will be by: A heliostat (from helios, the Greek word for sun, and stat, as in stationary) is a device that includes a mirror, usually a plane mirror, which turns so as to keep reflecting sunlight toward a predetermined target, compensating for the sun's apparent motions in the target may be a physical object, distant from the heliostat, or a direction in space.

Walker’s glass facet reflector’s gave about two thirds of the power of an equal diameter silvered metal reflector, and were estimated at about candlepower.

In this article, the most significant durability studies performed on the three main types of solar reflectors (glass-based, aluminum and silvered-polymer) .

This reflector provides the ultimate photo solution for all your photographic needs, it includes reflectors you need for most conditions.

The present state of the art in reflector materials for solar concentration includes back-silver-coated low-iron glass and silvered polymer films. These materials meet the past programmatic performance goals of maintaining greater than 90% specular reflectance for at least 5.

years in outdoor service (2). This is just a cheap 3" reflector like you would attach to a trailer, and by visual inspection it is obvious that some areas of the reflector are internally damaged and/or not as reflective as they should be.

It will probably work for what you need, but I found better 3" reflectors at a lower price in the automotive section of my local grocery/5(23). Following outdoor weathering, data Low-cost silvered polymer reflectors.

book obtained from several sample types as the performance of the silvered acrylic materials has been progressively improved. Silvered polymer reflectors o.o Angle (mrad) Fig. A radial distribution function of the reflected beam from ECP silvered acrylic film mounted on a glass by: 7.

A low iron glass mirror or very thin glass mirror of 1 mm or less in thickness has low absorption. The concentrator needs curved reflectors, and making the glass into the curved shape is cost intensive because the glass is fragile and rigid.

We, therefore, tried mirror facets to simulate the paraboloid by: The economic viability of these systems depends on developing a durable, low-cost reflector.

The goals for such a reflector are specular reflectance above 90% for at least 10 years under outdoor service conditions and a large-volume manufacturing cost of less than US$/m 2 (US$/ft 2).Cited by: Unweathered silvered-PMMA reflectors have a solar reflectance at least as high as glass reflectors, but their environmental durability needs to be demonstrated.

ECP, a silvered-PMMA film available commercially from the 3M Company and developed in collaboration with the National Renewable Energy Laboratory, is the current state of the by: polymer mirrors have advantages of being flexible, lightweight, and less expensive, but they have lower durability and shorter lifetimes than glass mirrors.

Recent improvements have been made in the performance and durability of silvered-polymer reflector materials [1,2].File Size: KB. The corrosion of the reflective layer is one of the main degradation mechanisms of solar reflectors. However, the appropriate assessment of the corroded reflector samples is not accomplished by the current analysis techniques.

The breakthrough goals that will be achieved in the development of the proposed low cost, Ultra-Specular Advanced (USA) mirror film are: 1) solar weighted hemispherical reflectance (SWHR) above 95%, 2) improved reflector specularity, with a beam spread below 1 mrad, 3) a service lifetime of 30+ years, without reflectance loss, even with direct.

Until a few years ago highly reflective aluminized sheet materials were predominantly used as reflectors for lamps in office and industrial buildings.

Because of their good mechanical properties and low cost compared to silvered glass mirrors, aluminized reflectors are finding applicability to high temperature solar concentrating by: Permatex Electrically Conductive Rear Window Defogger Tab Adhesive, Single Unit.

State-of-the-art low-cost solar reflector materials. Currently, the best candidate materials for solar mirrors are silver-coated low-iron glass and silvered polymer films. Polymer reflectors are lighter in weight, offer greater flexibility in system design, and have the potential for lower cost than glass mirrors.

Aluminized reflectors from other manufacturers exhibit similar performance. Recently, Alanod stopped selling this material for outdoor use because of problems associated with the delamination of the overcoat. The company is working to find a solution and to improve the abrasion resistance of the reflector [3].
