Frequently Asked Questions

Are portable solar panels effective?

Portable solar panels are an extremely effective, clean, and renewable way to charge a portable power station. EcoFlow 400W portable solar panels have a larger wattage than typical solar panels and are more efficient due to their monocrystalline cells. String up to three 400W portable solar panels and use with a DELTA Pro portable power station for an input of 1200W. Additionally, EcoFlow portable power stations use an MPPT algorithm to ensure a constant energy supply. Unlike static solar panels, portable solar panels are easily moved and adjusted depending on where the sun is in the sky.

Where do you place portable solar panels?

Positioning portable solar panels at an angle between 30-45 degrees, facing the sun's direction, is best. EcoFlow portable solar panels have a built-in stand that can be adjusted depending on the time of day.

Which solar panels are best for camping?

Solar panels that are portable, foldable, and lightweight are the best kind for camping. Pair with a portable power station for immediate power that is clean, green, and renewable.
