Quality control
In contrast to conventional solar panels, the SUNPOWER cells installed at SUNNYBAG have a significantly higher efficiency - namely 22.4%. To guarantee this, we test each panel for performance before shipping. The test certificate is enclosed with every SUNNYBAG and shows not only the achieved performance but also the day and time of the test. This way you can be sure that your SUNNYBAG delivers what it promises and that your devices are reliably supplied with renewable energy.
Optionally with POWERBANK
Our powerbanks are specially designed for charging with solar energy. They are the perfect temporary storage for the clean solar energy. The optimized power management (OPF technology) allows simultaneous charging and discharging. The powerbank stores the fluctuating solar energy efficiently and delivers it evenly to your smartphone. This is the most efficient way to use your SUNNYBAG.
