本文主要讨论了光伏系统中的设备与设计适用性。关键点如下: 1. 严格审查:IE(可能指独立工程师)在审查设计时关注项目的适宜性,包括设备是否符合相关UL标准,以及是否适合特定地点。 2. 项目风险评估:文章提供了表5.4,列出了地点的适宜性特征,如环境、极端温度、冰雹和洪水风险等,以及相关的风险量化。 3. 设备适宜性:考虑模块、跟踪器、逆变器、电池储能系统(BESS)和其他平衡设施的适宜性,包括认证、环境适应性、操作温度范围等。 4. 新模块的挑战:新模块由于缺乏性能数据,需要关注制造商、技术、认证、耐用性测试和退化验证。 5. 重要性:强调了银行性报告、设计基础、完整的测试报告和工厂审计报告对于简化IE工作的重要性。 核心数据引用: - HOMER Energy软件在超过190个国家使用,拥有超过25万用户。 - 现场条件量化了各种风险,例如,强风的中等风险,闪电密度为42.9 events/km²/年。 - 新模块的评估关键点包括制造商、技术、认证和耐用性测试。 总结:文章强调了在光伏系统中,设备和设计的适宜性是动态的,需要全面的评估和严格的标准遵守,以确保项目的成功和可持续性。
