The Jet Propulsion Laboratory (JPL), with funding from the 2012 SunShot Concentrating Solar Power (CSP) R&D FOA, is designing an optimized solar thermal collector structure using a lightweight collector structure capable of lowering structural costs, simplifying installation, and leading to mass-manufacturability.
The JPL project seeks to achieve the SunShot Initiative installed cost target of $75/m2 for a solar thermal collector system, as well as SunShot performance targets for optical errors, operations during windy conditions, and lifetime.
The specific project objectives are to:
- Design and develop a mirror module using an inexpensive reflective film bonded onto a lightweight structural rigid foam support
- Design and develop a low-cost, non-traditional mirror-module support structure
- Select low-cost drive components and associated control system
- Design, integrate, and test a low-cost concentrator
- Analyze the system's cost to demonstrate achieving the $75/m2 collector system target.
The cost of current concentrators can reach between 40% and 50% of the total installed costs for a CSP plant. The reflector module represents a key cost driver, which JPL's foam-based facet seeks to reduce significantly.
Optimized for cost, performance, and lifetime, the innovative JPL solar concentrator features:
- Durable thin-film mirrors (instead of mirrored glass) with high reflectivity for concentrating solar energy
- A mirror support structure that is 40% less expensive and reduces the weight of the system by more than 50%
- A mirror module that contains several facets and/or gores that facilitate simple transportation, installation, maintenance, and repair.
In addition, JPL's technology offers ease of manufacturability and can be modified easily for multiple types of CSP collectors.
