    • The invention relates to a method for producing solar powered screening devices (192) or windows (191) which comprise a motor for operating the device. The motor is powered via a battery and the battery is charged by a solar panel (104). In order to ensure that the solar panel is capable of producing sufficient energy, particularly when the screening device or window is installed at a location where the available solar energy is low, the solar panel is selected according to a test procedure. According to the test procedure at test voltage is applied to the solar panel and the resulting current is compared with the reference in order to find solar panels having sufficient conversion efficiency. The amplitude of the measured current depends on the efficiency, particularly in low light conditions.
    • 本发明涉及一种用于生产太阳能屏蔽装置(192)或窗口(191)的方法,所述屏蔽装置或窗口(191)包括用于操作所述装置的电机。 电动机通过电池供电并且电池由太阳能电池板(104)充电。 为了确保太阳能电池板能够产生足够的能量,特别是当屏蔽装置或窗口安装在可用太阳能低的位置时,根据测试程序来选择太阳能电池板。 根据测试过程中的测试电压施加到太阳能电池板上,并将所得到的电流与参考值进行比较,以便找到具有足够转换效率的太阳能电池板。 测量电流的幅度取决于效率,特别是在低光照条件下。
