1、太阳能节能楼宇直流供电系统设计摘要太阳能光伏发电系统由住宅小区负荷、太阳能电池方阵、检测系统、太阳能控制系统（单片机控制器）、DC-DC变换器、蓄电池组组成。白天，太阳能电池组件接收太阳输出电能，向蓄电池组充电；夜晚，直流系统经过控制器将蓄电池组输出的直流电供直流负载使用。系统中，太阳能电池组的功能是将太阳辐射能转换为电能；蓄电池的功能是将太阳能电池组输出的直流电加以贮存；防反充二极管的功能是用以阻止蓄电池组通过太阳能电池组件放电；检测系统的功能是检测各功能模块的信息，通过控制系统处理，实现控制保护功能；控制

2、系统的功能是主要对DC-DC变换器的通断和蓄电池组的过充电和过放电进行保护。本设计针对太阳能电池最大功率点的跟踪加以分析，设计中利用登山法解决太阳能电池最大功率点跟踪问题，此最大功率控制法对于日射量和温度大范围地变化具有高速、稳定跟踪特性，可以始终向系统的阻性负载提供最大功率。因此，可以确认此控制法是能够同时满足高速和高精度的最大功率控制法。太阳光发电作为洁净的和未来最有希望发光电方式之一，越来越受到人们的重视。光伏发电系统各个方面的研究都在不断地深入进行着。关键词太阳能电池；太阳光伏发电系统；最大功率点跟踪
