据BSW-Solar称，德国本周将其第300万个光伏系统接入电网。德国太阳能行业协会预计，该国最早将在明年突破400万大关，仅今年就新增了近35万套光伏系统。目前，德国的太阳能总装机容量已超过70 GW。
房主们正在对太阳能进行大量投资，2023年第一季度安装的新光伏系统数量是去年同期的两倍多。BSW Solar总经理Carsten Körnig将这129%的增长归因于能源危机和改善的框架条件下对太阳能技术的需求增加。
部署于阳台的插入式太阳能组件的普及程度也在上升，超过500万户家庭已使用自家屋顶的太阳能系统进行供电和供热。此外，德国大约有260万个太阳能供热系统，主要用于私人家庭的热水供应和空间供暖。
德国去年超额完成了7 GW的光伏扩张目标，如此看来，该国今年设定的9 GW目标也将有望实现。然而，联邦政府的目标是到2030年实现215 GW的光伏装机容量。
联邦网络局（Bundesnetzagentur）表示，根据线性外推法测算，要实现这一目标，每月需要增加约1.56 GW的光伏发电产能。Körnig强调，为了达到理想的太阳能利用率，在接下来的四年里，每年需要比前一年多安装大约30%的太阳能发电系统。
该协会的评估显示，德国三分之一的光伏发电容量安装于私人和商业建筑，以及开阔的土地。联邦政府计划将215 GW总目标的一半部署于屋顶和开放空间。
