guides or consult a reputable Solar installer or systems integrator. Dust building up on the surface of the
modules can impair module performance.YuHuan Sunpro Solar recommends installing the modules with a tilt
angle of at least 10°, making it easier for dust to be washed off by rain. Any faults caused by and/or attributable to
tilt angle less than 10 degrees are not covered by manufacturer's warranty. It is roughly equal to the latitude of the
project site as a rule of thumb, facing toward the equator. Optimized system designs must incorporate other local
requirements.
建议通过优化的倾斜角安装太阳能组件以达到能量输出最大化。对于详细的安装角度，请依据标准组件安装指
南或者有经验的光伏组件安装商给出的建议。玉环尚博建议组件安装的时候安装夹角不小于10°，这样组件在下雨
的时候表面灰尘容易被雨水带走，从而减小组件清洗次数，同时利于组件表面的积水流走，避免长期大量积水在玻
璃上留下痕迹，进而影响组件外观性能。任何由倾斜角度小于10度引起的故障不包括在制造商的保修范围内。一般
来说它大致等同于项目所在地的纬度，面向赤道方向。但在实际的设计中还是按照当地具体情况设计并找出最佳倾
斜角。
Installation inclination refers to the Angle between the PV module and the ground plane, as shown in Figure
5-1.
安装倾角是指太阳能光伏组件与水平面之间的角度，如图5-1所示。
