Photovoltaic Generation Dataset from the Federal Institute of Espírito Santo, Serra, Brazil

This dataset comprises historical records of photovoltaic generation in the city of Serra, ES, Brazil, obtained through automated web-scraping scripts from two distinct sources: KSTAR (referring to the Laboratório Espaço Energia — Casa Solar — 3.0 kWp) and SolarPortal (referring to the main generation panels of the Ifes Campus Serra photovoltaic plant — 119.0 kWp).

For the Ifes plant panels, the raw data covers the period from January 2023 to July 2025, whereas for the Casa Solar, the available records span from September 2023 to July 2025. Additionally, a set of processed data was produced, also through automated scripts, covering the period from December 2024 to July 2025. In the case of the Ifes plant solar modules, raw measurements were provided on a weekly basis from January 2023 until November 2024, after which they were made available exclusively in daily format.

A unified version of the processed data is also available, consolidated into a single .csv file for each source. This collection constitutes an essential foundation for analyses and diagnostics of the performance and operation of photovoltaic devices, as well as for assessing their impacts on the campus. Furthermore, it represents a valuable resource for teaching, research, and outreach activities within the academic community.

本数据集包含巴西圣埃斯皮里图州（ES）塞尔拉市的光伏发电（Photovoltaic Generation）历史运行数据，通过自动化网络爬虫脚本采集自两个独立数据源：KSTAR（对应空间能源实验室——卡萨太阳能（Casa Solar），装机容量3.0 kWp）以及SolarPortal（对应伊费斯（Ifes）塞尔拉校区光伏发电站的主发电面板，装机容量119.0 kWp）。
针对伊费斯校区光伏电站的光伏组件，原始数据覆盖时段为2023年1月至2025年7月；而卡萨太阳能的可用记录时间跨度为2023年9月至2025年7月。此外，通过自动化脚本还生成了一套处理后数据集，覆盖时段为2024年12月至2025年7月。就伊费斯校区光伏电站的光伏组件而言，原始测量数据在2023年1月至2024年11月期间按周频次发布，2024年11月之后仅提供日度格式数据。
此外还提供了处理后数据的统一版本，每个数据源均整合为单个.csv文件。该数据集可为光伏发电设备的性能与运行分析诊断、评估其对校区的影响提供核心基础，同时也为学术共同体的教学、科研及科普推广活动提供了宝贵资源。
