class="relatedlink">太阳能</a>光伏发电不消耗燃料、无噪声、无污染、没有地域限制等优势明显。同时，在政府推动下，光伏产业发展速度逐渐加快，十三五规划中制定了新目标，至2020年全国光伏装机总量将达到105GW以上，相比2015年的累计装机总量约43GW仍有超过62GW的增长空间。</div><div><br></div><div><p style="text-align:

例如，在光伏发电设备应用中，电流传感器的应用非常广泛，例如随着越来越多的分布式光伏发电系统接入到配电网中，常需要选取相应的电流传感器，来对电流直流分量进行检测，以将光伏电源对配电网的不利影响减到最小。<span style="line-height: 1.8em;">目前，直流分量的检测一般选用闭环电流传感器，闭环电流传感器具有精度高，线性误差小受外界干扰小的特点。对于直流分量的检测与一般的电流检测不同，叠加在交流信号的的直流分量幅值都很小，对传感器的要求也会更高。</span></div><div><br></div><div> 另一方面，在光伏产业的发展中，太阳能电池板表面落尘影响发电效率的问题也越发显现出来。相关数据<a href="http://display.oecr.com" target="_blank" class="relatedlink">显示</a>，在太阳能光伏发电领域，当光伏电池板表面积灰时，将造成5％到15％的发电量损失。而目前的人工擦洗方式，仍是国内光伏项目电池板主要清洁方法，耗时、费力、效率低。<span style="line-height: 1.8em;">近日，国内相关电气公司自主开发出了一款新型太阳能电池板清洁机器人。该机器人可全自动检测、清洁电池板，保持良好发电状态。据了解，该机器人可实现自动监测和启动，在轮子的带动下，沿着电池板两端的轨道滚动，缓缓向前爬行，其内部有螺旋式的毛刷转动，不用洒水就能将灰尘扫净。</span><span style="line-height: 1.8em;">据了解，该机器人便搭载有传感器，可对电池板表面进行检测，发现热板报警。同时，通过多种传感器及控制器的配合，还能实时检测并调整清洁功能部件的位置和姿态，进而适应颠簸不平的路面和参差不齐的光伏面板。研发方表示，该机器人经半年实验数据测算，使用该机器人及时清洁的太阳能电池板，发电量提升8％以上。</span></div><div><span style="line-height:
