All EcoFlow solar panels are designed to work seamlessly with the full EcoFlow ecosystem:

• RIVER Series (RIVER 3, RIVER 3 Plus) — Compatible with 45W, 60W, and 110W portable panels for fast and efficient solar charging.
• DELTA Series (DELTA 3, DELTA 3 Plus, DELTA 2 Max) — Compatible with 160W, 220W, and 400W panels for maximum solar input.
• Connection type: All panels use standard MC4 connectors, compatible with EcoFlow stations out of the box.
• Third-party panels also work as long as they use MC4 connectors and stay within the station's maximum solar input voltage and wattage.

It depends on the station capacity and available sunlight.

• RIVER 3 (245 Wh) — 1x 45W panel: approximately 6–7 hours. 1x 110W panel: approximately 2.5–3 hours.
• RIVER 3 Plus (600 Wh) — 1x 110W panel: approximately 6–7 hours. 1x 220W panel: approximately 3–4 hours.
• DELTA 3 Plus (1024 Wh) — 1x 220W panel: approximately 5–6 hours. 2x 220W panels: approximately 2.5–3 hours.
• DELTA 2 Max (2048 Wh) — 2x 220W panels: approximately 5–6 hours. 1x 400W panel: approximately 5–7 hours.
• Factors that affect charging time: Panel wattage, angle to the sun, cloud cover, shading, and ambient temperature.

Pro tip: Combining multiple panels in parallel significantly reduces charging time and maximizes daily energy harvest — especially useful for larger DELTA stations.

Yes, EcoFlow panels are not limited to EcoFlow stations only.

• MC4 Standard Connectors: All EcoFlow panels use industry-standard MC4 connectors — compatible with most portable power stations on the market.
• Check Input Voltage: Make sure your power station's maximum solar input voltage matches the panel's output voltage before connecting.
• Check Input Wattage: Stay within your station's maximum solar input wattage to ensure safe and efficient charging.
• Best Performance: EcoFlow panels are optimized and tested specifically with EcoFlow stations — pairing them together guarantees maximum efficiency and reliability.
• Universal Use: From Jackery to Bluetti and beyond — as long as your station accepts MC4 input within the right voltage range, EcoFlow panels will work.

Yes, but with reduced output.

• Light cloud cover: Output typically drops to 50–70% of rated wattage — still enough to meaningfully charge your station throughout the day.
• Heavy overcast: Output may drop to 10–25% — charging will be slower but still occurring.
• Rain and storms: Minimal output, but panels continue to generate small amounts of power even in poor conditions.
• Best practice: On cloudy days, keep panels angled toward the brightest part of the sky and avoid shading from trees or buildings.
• Bottom line: Solar panels are not dependent on direct sunlight — daylight is enough to generate power year-round.

With proper care, EcoFlow solar panels can last 10+ years.

• Cleaning: Wipe panels with a soft damp cloth regularly — dust, dirt, and bird droppings can reduce output by up to 25%.
• Storage: Store portable panels folded in a dry, cool place away from direct sunlight when not in use. Avoid bending or creasing the panel surface.
• Avoid shading: Even partial shading of one cell can significantly reduce the output of the entire panel — always position panels in full daylight.
• Cable care: Inspect MC4 connectors and cables regularly for damage or corrosion. Replace damaged cables immediately to avoid efficiency loss.
• Temperature: Panels perform best in cool, sunny conditions. Extreme heat can slightly reduce output — ensure good airflow underneath rigid panels when mounted.
• Long-term storage: If storing for several months, keep panels in their original case or a protective bag to prevent scratches and moisture damage.
