Quantifying the Value of Foam-Based Flexible Floating Solar Photovoltaic Systems

This thesis investigates using a flexible crystalline silicon-based FPV module backed with foam, which is less expensive than conventional pontoon-based FPV. This novel form of FPV is tested experimentally for operating temperature and performance and is analyzed for water-savings using an evaporation calculation. The results show that the foam-backed FPV had a lower operating temperature than conventional pontoon-based FPV, and thus a 3.5% higher energy output per unit power. A case study of Lake Mead found that if 10% of the lake was covered with foam-backed FPV, there would be enough water conserved and electricity generated to service Las Vegas and Reno combined. At 50% coverage, the foam-backed FPV would provide over 127 TWh of clean solar electricity and 633.22 million m3 of water savings.

Potential of Floating Photovoltaic Plant in a Tropical Reservoir in Brazil

This article reports findings of a simulation performed to assess the potential of floating photovoltaic power generation in the tropical Gavião reservoir, located in the Northeast of Brazil. The payback analysis indicates that the investment for construction of the system is fully recovered in 8 years, and that water losses due to evaporation can be reduced by approximately 2.6 x 106 m³/year, enough to supply roughly 50,000 persons.

Made in the Shade: Promoting Solar Over Water Projects

This Idaho Law Review publication discusses existing policies in many jurisdictions that create unjustifiable obstacles to solar over water development. It uses the ongoing effort to install solar panels above portions of the Central Arizona Project’s canal system as a case study to highlight the significant potential benefits of solar over water development. The article then identifies specific policy changes capable of better facilitating and promoting these innovative and uniquely valuable renewable energy projects.

Powering the Blue Economy: Exploring Opportunities for Marine Renewable Energy in Maritime Markets

This U.S. Department of Energy’s Water Power Technologies Office report describes marine and coastal opportunities for which marine energy could fulfill those energy needs. The major finding is that there are more markets with potential than anticipated, both for Power at Sea (including ocean observation and navigation, underwater vehicle charging, marine aquaculture, marine algae, and seawater mining), and Resilient Coastal Communities (including desalination, coastal resiliency and disaster recovery, and community-scale isolated power systems).

Distributed Manufacturing of After Market Flexible Floating Photovoltaic Modules

In this study, an open-source, after-market distributed manufacturing method is proposed to be applied to large flexible PV modules to make flexible FPV systems. The results of this preliminary study indicate that foam-backed FPV is exceptionally promising and should be further investigated with different foams, larger systems and more diverse deployments for longer periods to increase PV deployments.
