BrightSource Energy, under the 2012 SunShot Concentrating Solar Power (CSP) R&D FOA, is designing and deploying an automated collector-assembly platform. The researchers are also developing a more efficient installation process that has the potential to drastically reduce construction time and cost for utility-scale CSP facilities.
BrightSource's research objective is to design, build, and demonstrate a Flexible Assembly Solar Technology (FAST) system that can substantially reduce the cost and time associated with solar-field construction. FAST accelerates the heliostat assembly and field installation processes by combining elements of both functions on a single platform with direct access to the solar collector field. The system incorporates:
- Preliminary, partial assembly of the mirror units at a centralized offsite facility capable of supplying multiple CSP projects
- An automated, transportable FAST platform for assembly completion
- Delivery of the fully completed assemblies into the solar field for final installation.
By eliminating the conventional heliostat assembly building (HAB), FAST substantially reduces solar-field construction time and cost, reduces the need for onsite storage, and avoids costs related to permitting, construction, maintenance, operation, and demolition of the HAB. The FAST process also allows for flexible deployment to multiple power tower sites in accordance with project design and schedules. In addition, FAST will complement and enable a next-generation heliostat design, thereby leveraging further cost reductions.
The novelty of the project is in the application of automation processes to solar project sites. The system is integrated with the design of the new, low-cost heliostat, which is modified to facilitate FAST assembly. The system enables deployment of collectors that lend themselves to automated manufacturing, minimal site preparation, and rapid installation. This project addresses crucial barriers to cost and risk reduction to meet the SunShot Initiative's target installed solar-field cost of $75 per square meter.
