太阳能路灯工程设计的关键是太阳能电池组件、蓄电池、照明光源的配置组合达到最优。照明光源功率确定后较易匹配蓄电池容量。由于光照受气候环境、地理位置的影响较大，因此选择合适功率的太阳能电池组件非常关键。依据理论计算或气象资料设计方法确定的太阳能电池组件容量偏差较大。在常规设计方法基础之上，将计算出的145 W 太阳能电池组件容量调整为80 W，通过连续实时跟踪监测，结果表明：该设计降低了系统成本，节省了使用空间。

The key to solar street lighting project design is the best combination of solar module, storage battery and lighting configuration. After the determination of lighting power, the battery capacity can be easily matched. Since light is impacted greatly by climate and geography, choosing a suitable power solar module is very important. Based on theoretical calculation or meteorological data design method, the calculated capacity of the solar module has large deviation. Based on conventional design methods, the solar module capacity is adjusted to 80 W from calculated 145 W. After continuous real- time tracking and monitoring, the results show that the design meets the design requirements, reduces system cost and saves the use of space.
