据风险专家VDE Americas称，冰雹可对太阳能装置造成严重损坏，是造成一半投保项目损失的根本原因。虽然冰雹无法避免，但可通过倾斜跟踪器上的太阳能组件（即“收起”）来防止在雹灾中受损。
总部位于得克萨斯州的太阳能跟踪器专家FTC Solar推出了“防雹自动收起解决方案”，利用气象数据，在冰雹即将来临时自动收起太阳能组件。
在与VDE Americas合作研究雹灾对太阳能装置的影响后，FTC Solar开发出防雹收起策略，通过太阳能组件定位来最大限度地减少冰雹和大风的直接影响。
该自动防雹收起解决方案与FTC Solar的Sunops集成，后者是一个基于云的光伏资产监控解决方案，旨在管理和改善太阳能资产性能。FTC报告称，该软件考虑了先进的跟踪算法和适当的跟踪器收起方式等因素，以应对极端天气事件。
FTC Solar首席营销官Ken Kozizki告诉《光伏》杂志美国版，跟踪器可根据气象预测数据，迅速移动到大于50度的防雹收起位置，使组件朝向避风方向。该防雹算法由FTC从行业领先的第三方供应商处获得的气象数据驱动，通过多个雷达对天气状况加以分析，从而形成对单个地点的准确预测。
Kozizki说，还有一项功能允许发电站经理手动移动到最近的高角度收起位置，以进一步减少收起时间，还可根据风险偏好和现场位置，包括冰雹大小、概率和半径等因素，定制收起阈值。
