Frequently Asked Questions
Can I use a 350W solar panel with a 200W power station?
Yes you can use a higher wattage panel with a smaller station but the charging speed will be limited by the station's max input. The extra power is simply ignored so ensure the voltage matches.
Are these panels waterproof?
Most models come with IP65 IP67 or IP68 ratings. IP68 is fully waterproof while IP65 handles rain. Always check the specific rating before exposure.
How long does it take to charge a generator?
Charging time depends on the generator size and sunlight intensity. A 350W panel can charge a 1kWh battery in 3-5 hours of direct sun.
Do I need a solar charge controller?
Most portable panels have built-in regulators. However rigid modules often require an external MPPT controller for best performance.
Can I connect two 350W panels together?
Yes many panels support series or parallel connections. You will need Y-cables to combine outputs effectively.
What is the lifespan of a portable solar panel?
Quality panels last over 25 years with proper care. ETFE coatings help extend this by resisting degradation.
Do I need to clean the panel regularly?
Cleaning every few weeks ensures peak efficiency. Use mild soap and water to remove dust or debris.
Is N-Type better than P-Type?
N-Type cells are more efficient and resistant to degradation. They perform better in heat and low light.
