The broader impact/commercial potential of this Small Business Innovation Research (SBIR) project is to bring to market a novel self-buoyant panel that will enable floating photovoltaics (FPV) to play an important role in achieving the Nation’s clean energy goals. The Federal Solar Futures Study describes a goal to generate over 40% of the nation’s electricity using solar, which would require a 10x increase. However, this would require 10 million acres by 2050 – an area larger than New Jersey. FPV systems can directly mitigate land displacement. According to NREL, the 24,419 US bodies of water have a technical potential of over 300 GW. The barrier to scaling deployments is the cost premium of the artificial island needed to support panels, which can increase system costs by 30% compared to ground-mounted utility scale solar arrays. The proposed solar panel design floats uses sealed photovoltaic (PV) glass tubes and no mounting hardware to solve the cost premium. Further, the PV tubes track the sun like 1-axis trackers, but with no moving parts, to increase energy yield by 10-20%. These systems could become the cheapest form of solar. This SBIR Phase I project proposes to address the key barriers to commercialization of the proposed FPV technology. Realizing the market and impact potential of this solution requires retiring multiple risks and achieving several milestones that are address in the proposed project. The company will refine and test functional tubes that are hermetically sealed at the ends to maintain floatation and protect the solar cells. The company will team with one of the premier US marine renewable energy research institutions, to study multiple aspects of the design. First, the project will focus on a robust structural system that meets operating requirements. The project will research using simulation tools the mooring system and panel configurations needed for a range of wave and wind conditions. Additionally, a key element of a self-buoyant approach requires knowledge of potential biological factors that can impact solar production and panel performance. Accordingly, this investigation will also study the potential effects of biofilms and other environmental factors on PV tubes.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个小型企业创新研究(SBIR)项目的更广泛的影响/商业潜力是将一种新型的自浮式电池板推向市场，该电池板将使浮动光伏(FPV)在实现国家清洁能源目标方面发挥重要作用。联邦太阳能期货公司的研究描述了一个目标，即使用太阳能发电占全国发电量的40%以上，这将需要增加10倍。然而，到2050年，这将需要1000万英亩--这个面积比新泽西州还大。FPV系统可以直接缓解土地位移。根据NREL的数据，美国24419个水体的技术潜力超过300千兆瓦。扩展部署的障碍是支持电池板所需的人工岛的成本溢价，与地面安装的公用事业规模太阳能电池板相比，这可能会使系统成本增加30%。拟议的太阳能电池板设计浮动使用密封的光伏玻璃管，没有安装硬件，以解决成本溢价。此外，光伏管像1轴跟踪器一样跟踪太阳，但没有移动部件，将能量产量提高了10%-20%。这些系统可能成为最便宜的太阳能形式。该SBIR第一阶段项目建议解决拟议的FPV技术商业化的主要障碍。实现此解决方案的市场和影响潜力需要消除多个风险，并实现拟议项目中涉及的几个里程碑。该公司将改进和测试末端密封的功能管，以保持漂浮并保护太阳能电池。该公司将与美国一流的海洋可再生能源研究机构合作，研究设计的多个方面。首先，该项目将重点放在满足运营要求的强健结构系统上。该项目将使用模拟工具研究各种海浪和风力条件下所需的系泊系统和面板配置。此外，自浮式方法的一个关键要素需要了解可能影响太阳能生产和电池板性能的潜在生物因素。因此，这项调查还将研究生物膜和其他环境因素对光伏管的潜在影响。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
