Frequent questions

Are Portable Solar Panels Effective?

Portable solar panels are an extremely efficient, clean and renewable way to charge a portable power station. The EcoFlow 400W portable solar panels have a higher electrical output than traditional solar panels and are more efficient thanks to monocrystalline cells. Up to three 400W portable solar panels can be connected and used with a DELTA Pro portable power station to achieve a power output of 1200W. In addition, EcoFlow portable power stations use an MPPT algorithm that ensures a constant supply of energy. Unlike static models, portable solar panels can be easily moved and adjusted depending on the position of the sun in the sky.
