The research team performed a detailed bottom-up manufacturing cost estimate for an advanced parabolic trough design — the Solar Dynamics Sunbeam-MT (Sunbeam Mid-Term). This includes all components and assembly in facility (e.g. space frame arms), purchased parts mirrors receiver tubes). Estimates of construction activities have been made to then determine estimated installed cost. Prior analys...

Parabolic concentrator mirrors are an important component of many solar energy systems, particularly solar mirror collectors. Precision parabolic mirrors are expensive to fabricate and to transport. Here, a new concept for designing and fabricating precision parabolic mirrors is presented. The mirror is formed from a thin flat very flexible metal sheet with a highly reflective surface. Attached...

Parabolic trough[1] is the most mature technology for large scale exploitation of solar energy. Several power plants based on this technology have been operational for years, and more are being built. However, the current technology suffers from a too high installation cost. This high cost makes it very hard to compete economically with fossil energy without government subsidies, compromising t...
