自2022年冬季开始以来，受俄罗斯和乌克兰战争的影响，欧洲的能源短缺问题逐渐出现，太阳能已经成为热能源。
最近，有一个热潮阳台太阳能系统在德国。这个简单plug-and-play solar systemrequires only an AC power outlet, without a distribution box, and can be installed by non-professionals, so it has attracted much attention.同时，微型逆变器已成为许多人的首选。
什么是balcony solar? Why invest in balcony solar? How to choose a balcony microinverter? Details are as follows.
具有成本效益的初始投资。只有一个或两个太阳能电池板和一个通常具有5-10米长的电缆长度的微型逆变器可以构建阳台太阳系。
Referring to the general price in the Europe, a solar panel is 200-400 Euros, and a microinverter is 100 Euros. If you buy two panels, you can realize your solar energy investment plan for less than 1,000 Euros.
准备工作：首先观察阳台栏杆的状况以检查稳定性，然后检查阳台的方向。以北半球为例，最好将面向南方的太阳能电池板放置。
太阳能电池板：根据安装手册安装固定零件，然后小心地将太阳能电池板悬挂在栏杆上或准备好的支架上以检查稳定性。支架更安全，因为它们安装在斜坡上的地板上。面板的比例由阳台区域确定。
微型逆变器：在适当位置的微型逆转录AC总线预先安装AC总线，将微量逆变器安装在括号or on the frame of the solar panel, closely connect the AC port with the AC bus connector. Finally insert the plug into the AC outlet to power on.
After powering on, the solar panel on the balcony generates direct current after being irradiated by sunlight. The microinverter converts direct current into alternating current, and then supplies it to household loads such as washing machines, refrigerators, and air conditioners. Excess electricity will be sent to the public grid.
In the northern hemisphere, for example, the panels are placed on balconies facing south, and in the southern hemisphere facing north.
According to the survey, placing the panels at a 45-degree angle to the horizontal line, and placing them at different directions in the morning and evening, can effectively increase the power generation.
随着温度的升高,最大输出功率of the solar panel will decrease, and the conversion efficiency of the microinverter will also decrease. In order to avoid the influence of temperature on the power generation, the panel should be kept in good ventilation conditions.
面板放置在户外，其灰尘将导致生产能力损失，约为4-6％。阳台面板比屋顶更容易清洁，应经常擦除以减少灰尘对发电的影响。
最大功率点跟踪（MPPT）是可变电源的一种技术，可跟踪太阳能电池板的最大输出功率点。The MPPT function of the on-grid system will be completed in the inverter, so it is important to select a suitable one.
太阳激励措施非常重要。您可以根据购买费用获得50％的税收减免，这可以在10年内通过纳税申报表收回，或者通过将50％的信贷转移给安装面板的人，从发票中扣除。
与屋顶PV阵列相比，阳台太阳能系统的前期成本较低，可以节省您的电费，该电源无法存储，并且大部分将用于您的房屋设备中。合理的电力消耗时间分配可以有效节省电费。
移动或露营时可以携带。小型太阳能电池板和微型逆变器都是便携式的，您可以将它们放在汽车的后备箱中并与您一起旅行。
不需要自建筑物的大屋顶，只有一个宽敞的阳台，充足的光；无需雇用专业人员即可安装，但要自己实现插件，从而节省了安装成本。
