A glass concentrator for manufacture of solar energy conversion module is provided including a webbing that has a load sustenance characteristic and a hail impact resistance characteristic based on a first thickness of the webbing. The concentrator also includes a plurality of elongated concentrating elements integrally formed with the webbing. Each of the elongated concentrating elements has an aperture region, an exit region and two side regions, which bears a geometric concentration characteristic provided by a highly reflective side regions and an aperture-to-exit scale ratio in a range from about 1.8 to about 4.5. The glass concentrator can be attached with a plurality of photovoltaic strips cumulatively on each and every exit regions and clamped with a rigid or flexible back cover member to form a solar concentrator module for converting sunlight to electric energy. The solar concentrator module based on certain embodiments meets the industrial qualification standards.
