对化石燃料驱动的能源供应的依赖是全球排放的一个主要因素。为了保持在《巴黎协定》的温度上升限制范围内，目前和不断增长的能源消费将需要通过部署低碳/无碳发电来大力支持。这项工作促进了部署在未开发停车场的太阳能光伏（PV）系统的兆瓦级发电，据估计，这些停车场占城市内城市足迹的6.6%。开发的方法是全球适用于支持光伏开发，包括选址和光伏阵列配置。它得到了一个大学校园案例研究的支持，该大学校园的占地面积与城市停车场的占地面积相似。该方法表明，只有不到1%的可用停车位受到周围建筑物或植被阴影的影响。这项工作表明，通过在选定的校园内利用这样的停车场，一个容量为36.4兆瓦的光伏装置是可行的，每年可以产生66.2吉瓦时的电力。基于多种情景的财务分析表明，在出口电价为4.5美元/千瓦时的情况下，25年内可实现50%的投资回报率，这与最近批准的类似出口电价投标相当。
Reliance on fossil fuel-driven energy supply is a major contributor to global emissions. In order to stay within the Paris Agreement's temperature rise limits, current and growing energy consumption will need to be significantly underpinned by deployment of low/non-carbon power generation. This work promotes power generation at the megawatt scale from solar photovoltaics (PV) systems deployed in untapped car parking areas, which are estimated to represent up to -6.6% of the urban footprint within cities. The methodology developed is globally applicable to support PV development, including site selection and PV array configuration. It is underpinned by a case study in a university campus, which has a similar footprint as assigned in cities for vehicle parking. The methodology demonstrates that less than 1% of the available parking spaces are affected by shadows from surrounding buildings or vegetation. The work shows that by utilising such parking areas within the selected campus a PV installation with a capacity of 36.4 MWp, which can generate -66.2 GWh of electricity annually, would be feasible. Financial analysis based on multiple scenarios indicates that a 50% return on investment is achievable over 25 years at an export tariff of USD phi 4.5/kWh, which is commensurate with the latest granted bids for a similar export tariff.
