❓ How many watts do I need in a portable solar panel?
Phone charging: 10-21W. Multiple devices: 28-60W. Power station charging: 100-200W. Running a campsite: 200-400W. Start small and add panels as needed.
❓ Can solar panels charge in cloudy weather?
Yes, but at reduced efficiency (10-30% of rated output). MPPT charge controllers help maximize output in low-light conditions. Plan for extra charging time on overcast days.
❓ What is the difference between mono and polycrystalline panels?
Monocrystalline panels are more efficient (20-23%) and compact. Polycrystalline panels are cheaper but less efficient (15-17%) and larger. Mono is better for portable use.
❓ How do I connect a solar panel to a power station?
Most portable power stations have an XT60 or Anderson input for solar. Match the panel voltage and amperage output to the station input specs. Use compatible cables.
