Abstract
A solar system comprising a reflector and a heat collecting element (HCE) received at the focus of the reflector. The HCE comprises a coated tube received within a coaxial evacuated enveloping glass tube. The enveloping glass tube is secured at respective ends thereof to the coated tube by a coaxially deformable connector element having a distal end thereof sealingly secured to the coated tube and a proximal end thereof sealingly attached to a respective end of the enveloping glass tube by a glass to metal connection (GMC). A radiation shield assembly is provided over the connector element and over the GMC and is secured to the connector element by support legs engaging the connector element adjacent the proximal end.
