Weathering Fresnel reflector

The effects of weathering at locations such as Florida and Arizona can be accelerated by using panel mountings that track the sun, combined with metal Fresnel reflectors to concentrate the rays of the sun, water sprays and cooling devices. This method is known by the initials EMMAQUA which stand for equatorial mounted mirrors with water spray (AQUA). By such means, one year of normal Florida weathering can be achieved in approximately 40 to 45 days [4] and this is therefore a very cost-effective method for materials needing a long service life.
