A non-tracking solar thermal system with low concentration and a simple receiver at a reasonable cost, can have a positive disruptive effect on the Indian process heat sector. The present project proposes to develop a low concentrating compound parabolic concentrator (CPC) based non-tracking solar thermal system with a simple copper-finned tube absorber, having a selective coating typically used for flat plate water heaters, but with low conductivity glazing made of aerogel with high transmissivity for optical wavelengths and low transmissivity for thermal (infrared) wavelengths. The research on such a material with good insulating properties and excellent greenhouse properties was attempted in the past but not taken up further due to cost limitations. This kind of aerogel is presently developed and tested at MIT Boston which seems to be a suitable solution, at an affordable cost. However, the development and the testing of suitable modules and integration with thermal storage systems appropriate for process heat requirements for different sectors of Indian industry is needed. The proposed design can easily be fabricated (and eventually manufactured) in India.
