Concentrating Solar Power (CSP) is used to generate clean electricity from the sun, normally at utility scale. It is particularly suitable for areas with high Direct Normal Solar Irradiance (such as Spain, California and the Middle East). In CSP, a set of mirrors is used to concentrate the sun’s rays on a central receiver. This heats up a liquid which is then used to generate electricity in a conventional thermodynamic cycle.
AGC's solar glass range includes high reflectivity solar mirrors as well as high transmission solar glass substrates (Sunmax) to be used for solar concentrators and solar receivers.

AGC solar mirrors for the Ashalim Solar Thermal Power Station
At the Ashalim Solar Power Station in the Negev desert in Israël, more than 50,000 computer-controlled heliostats, each made of 4 solar mirrors, track the sun and reflect sunlight onto a boiler (the solar receiver) on top of a 240-meter tower. The boiler heats up a liquid and converts it into steam. The steam powers a turbine to produce electricity. The heliostats are equipped with 750.000 m² of AGC’s Sunmax Premium Reflect (4mm), a highly reflective mirror that is extremely resistant to withstand outside conditions (sand, wind, sun) of the desert. The 121 MW Ashalim Plot-B solar-thermal project supplies 320 GWh of electricity annually into Israel’s grid. The electricity generated by the whole Ashalim solar complex is enough to supply 120,000 homes with clean energy. The complex will avoid 110,000 tons of CO2 emissions each year over the course of its life.
