The largest power will be generated When direct sunlight on Solar PV module. For modules which are installed
on the fixed brackets, the best installation angle should be selected to ensure the maximum power output can be
generated at winter time, if the angle can guarantee enough power output during the winter, it will make the whole
Solar PV system in the rest of the year can have enough power output also.
当阳光直射到太阳能光伏组件上时产生的功率最大，对于那些安装在固定支架上的太阳能光伏组件，选择最佳
的安装倾角时应考虑冬季的太阳能光伏组件的功率产出，如果该角度能保证光伏组件在冬季有足够的功率输出，那
将会使整个太阳能光伏组件体系在一年中的余下时间里也能有足够的功率产出。
Solar modules are recommended to be installed at an optimized tilt angle to maximize the energy output. For
detailed information on the best installation angle, please refer to standard Solar photovoltaic installation 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。赛拉弗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

所示。
