The EcoFlow 4 × 250W Solar Panel set is a complete four-panel kit built around TOPCon monocrystalline modules delivering 250 W (±5 W) each and a peak conversion efficiency of up to 23%. Each panel weighs 10 kg and measures 115.7 × 116.5 × 2 cm, and the set ships with cables to connect the panels to the STREAM micro-inverter along with velcro straps and metal straps for hanging the modules through their mounting holes on a balcony railing or similar structure.

• Set of four rigid 250 W (±5 W) TOPCon monocrystalline solar panels with a peak conversion efficiency of up to 23%.
• Includes the connection cables needed to hook the panels up to an EcoFlow STREAM micro-inverter.
• Velcro straps and metal straps included to attach the panels through their mounting holes to a balcony railing or comparable structure.
• Maximum system voltage of 150 V per panel keeps the wiring window compatible with residential balcony solar setups.
• Low temperature coefficient of −0.30 %/°C on rated power for consistent summer output on a sun-facing balcony.
• 5-year manufacturer warranty on the panels.
