Does rain affect solar panels?

Yes, rain reduces solar panel output significantly, but Sokiovola portable solar panels are built to handle wet conditions — the panel surface carries an IP68 rating, meaning it can withstand rain without damage.

Rain affects solar panels in two ways: physically and electrically. On the electrical side, heavy cloud cover accompanying rain typically drops output to 10–25% of rated wattage; light drizzle under bright cloud cover may still deliver 40–60%. On the physical side, Sokiovola's ETFE-laminated panel surface and waterproof dragon dance cloth backing handle rain exposure reliably — but the junction box and output ports are not IP68-rated and should be kept dry during heavy rain to prevent connector damage.

• Sokiovola panel surface and backing carry an IP68 rating; junction box and ports do not.
• Heavy overcast or rainstorm conditions typically yield 10–25% of a solar panel's rated STC wattage.
• Light cloud cover with drizzle typically yields 40–60% of rated wattage on N-type 16BB panels.
• Sokiovola's ETFE coating transmits up to 95% of incoming light, outperforming PET-coated panels in diffuse light conditions.
• N-type 16BB cells perform better than P-type cells in indirect or diffuse light, but rain-related cloud cover still substantially reduces output.
