NOVELTY - The sealed solar energy equipment e.g. solar concentrators comprises an outer surface having a transparent side, inner elements, and a layer of sealant on the outer surface for forming a bond to the outer surface. The sealant layer is optically transparent on a portion of the outer side having an optical transparent surface. The optical transparency of the sealant is in the wavelength of 2000-7500 Angstrom . One of the sealant layers is a hard sealant, a high index of refraction sealant, a hydrophobic sealant or a binder layer, and is bonded to an inner element.    USE - Used as a sealed solar energy equipment such as solar concentrators, optical switches and reflection, illumination and projection equipment.    ADVANTAGE - The sealed solar energy equipment has improved abrasion resistance, static dust attraction and weatherability thus reducing its damage during normal usage, and prevents the scratching and egress of the lubricant or ingress of undesirable fluids using the sealant layer thus increasing its longevity and performance.    DETAILED DESCRIPTION - The sealed solar energy equipment e.g. solar concentrators comprises an outer surface having a transparent side, inner elements, and a layer of sealant on the outer surface for forming a bond to the outer surface. The sealant layer is optically transparent on a portion of the outer side having an optical transparent surface. The optical transparency of the sealant is in the wavelength of 2000-7500 Angstrom . One of the sealant layers is a hard sealant, a high index of refraction sealant, a hydrophobic sealant or a binder layer, and is bonded to an inner element. The hard sealant layer is placed on a surface of the equipment. The hydrophobic layer is placed on the hard sealant layer. An INDEPENDENT CLAIM is included for a method for maintaining the integrity of solar energy equipment.
