Abstract Solar inverter providers optionally offer plant operators online access to their installed photovoltaic (PV) systems. Benefits consist of better system monitoring, faster response to maintenance needs, and a more comfortable data acquisition. Data mining from an online database enables a comparative statistical analysis for a large number of plants about specific productivity parameters, emission reductions and monetary savings. Restriction of information usually confines the progress of PV systems. Due to this situation, the Sunnyportal website managed by one of the most important world provider of solar inverters does not delimit the visualization of their own systems. In addition, there is unrestricted access to their available plants in cases where the owners set the status of their plants as “public”. This study gathered and analyzed information on photovoltaic installations in Mexico with free access to production data. The results show an increase of almost 700% in the number of registered plants in Mexico with exponential growth since 2012. Mexico still shows a lack of studies regarding the monitoring of PV systems because available data are scarce. The specific productivity rate of the PV systems primarily depends on solar irradiation on-site, weather conditions, air contamination, the technology employed, correct engineering and plant maintenance. Based on data obtained, conclusions are drawn concerning preferences and performance of Mexican PV plants. The most both surprising as well as important result is that there is no correlation between specific productivity and average daily on-site irradiation.

墨西哥光伏电站现状——基于在线监测的分析

摘要 太阳能逆变器供应商可选择为工厂运营商提供对其安装的光伏 (PV) 系统的在线访问。好处包括更好的系统监控、对维护需求的更快响应以及更舒适的数据采集。从在线数据库中挖掘数据可以对大量工厂进行关于特定生产力参数、减排量和资金节省的比较统计分析。信息的限制通常会限制光伏系统的进展。由于这种情况，由世界上最重要的太阳能逆变器供应商之一管理的 Sunnyportal 网站没有限制他们自己系统的可视化。此外，如果所有者将其工厂的状态设置为“公共”，则可以不受限制地访问其可用工厂。本研究收集并分析了墨西哥光伏装置的信息，可免费获取生产数据。结果显示，自 2012 年以来，墨西哥注册的工厂数量增加了近 700%，呈指数增长。由于可用数据稀缺，墨西哥仍然缺乏关于光伏系统监测的研究。光伏系统的特定生产率主要取决于现场太阳辐射、天气条件、空气污染、所采用的技术、正确的工程设计和工厂维护。根据获得的数据，得出关于墨西哥光伏电站的偏好和性能的结论。最令人惊讶和重要的结果是比生产率和平均每日现场辐照之间没有相关性。
