Rioglass Solar is a global leader in designing and manufacturing optical CSP and CPV components. Founded in 2007, Rioglass Solar is now the largest supplier of CSP HCE tubes and concentrating mirrors in the world.

Capitalizing on its extensive knowledge and experience, Rioglass has created a turn-key solar solution to generate process heat for industrial applications. Our Engineers have developed a Fresnel system not seen before generating process heat at a much lower cost while at the same time eliminating fossil fuels and therefore reducing the customers carbon foot print. This Rioglass breakthrough design enables us to manufacture, assemble and calibrate these amazing modules at our facilities worldwide so the equipment is ready to be installed when it arrives at the customer’ site. These “Plug and Play” systems are designed to work with a variety of heat transfer fluids.

The world class staff at our glass fabrication facilities designed a Fresnel system using very precise and accurate TEMPERED CURVED lenses with 6 different curvature radios within each module, making it the most efficient solar collector system in the market today to produce industrial process heat. Rioglass’ Clients can be Environmentally conscious while reducing cost at the same time.

Rioglass is the only Manufacturer that has complete control over the entire supply chain. All major components are produced within the Rioglass Group guaranteeing consistent quality and timely deliveries.
