摘要

太阳能光伏(PV)技术为减轻加密货币矿工的环境和电力成本挑战提供了一种有前途的手段。为了分析这一前景,本研究调查了使用单独优化的光伏系统供电的可行性:1)个人比特币矿工,2)拥有50个矿工的DIY多式联运集装箱,以及3)拥有408个矿工的商业采矿农场集装箱。在一个受控的实验室环境中,矿工的用电情况受到监控。然后利用这些值,研究了基于比特币价格、比特币减半事件和矿工硬件的光伏系统收益率和灵敏度范围的数值模拟,以进行明智的财务规划。此外,还分析了北美地理位置、公用事业电价和光伏资本成本的敏感性。盈利能力和投资回报率(ROI)因地点而异,主要是因为太阳通量和利用率的地理分布。由于电力成本低,多伦多和蒙特利尔使用光伏与比特币挖矿的投资回报率为负,而卡尔加里的投资回报率为8%。在被评估的美国城市中,投资回报率相当可观,从纽约的34%到博尔德的64%,再到洛杉矶的104%。虽然这项研究是在北美进行的,涉及能源价格、气候和能源法,但分析方法在全球范围内是通用的,并为普通加密货币企业提供了从财务和环境角度做出明智决定的知识。这项研究通过为加密货币矿工提供可再生太阳能,为保护环境提供了一种经济手段,从而为加密货币挖矿的知识体系做出了贡献。

Economics of Open-Source Solar Photovoltaic Powered Cryptocurrency Mining
Solar photovoltaic (PV) technology offers a promising means to alleviate environmental and electricity costs challenges for cryptocurrency miners. To analyze this promise, this study investigated the feasibility of using electricity from individually optimized PV systems to power: 1) an individual Bitcoin miner, 2) a DIY intermodal shipping container holding 50 miners, and 3) a commercial mining farm container holding 408 miners. In a controlled lab environment, miners were monitored for electricity use. Then using these values, numerical simulations of both the PV system yield and sensitivity ranges based on the Bitcoin price, Bitcoin halving events, and miner hardware were investigated for informed financial planning. In addition, sensitivity for geographic locations in North America, utility electric rates and PV capital costs were analyzed. The profitability and return on investment (ROI) varied by location primarily because of the geographic distribution of solar flux and utility rates. The ROI for using PV with Bitcoin mining was found to be negative for Toronto and Montreal because of low-cost electricity, while it was 8% for Calgary. In the U.S. cities evaluated, the ROIs were substantial and ranged from 34% in New York, to 64% in Boulder, and up to 104% in Los Angeles. Although the study is based in North America regarding energy rates, climate, and energy laws, the analysis methodology is generalizable globally and grants the average cryptocurrency business the knowledge to make an informed decision on whether to pursue this venture from a financial and environmental perspective. This study contributes to the body of knowledge in cryptocurrency mining by providing an economic means of environmental preservation by powering cryptocurrency miners with renewable solar energy.
