Review about the Eco-worthy 10W solar panel bought from Aliexpress (also available on Ebay).
Link to item: http://www.aliexpress.com/item/10W-So…
Specified parameters:
Model: Eco-worthy ICO-SPB-10W
Maximum power voltage: 17.3V
Maximum power current: 0.54A
Actual parameters:
Maximum power voltage: 20.7V
Maximum power current: 0.40A
Temperature 50 degrees Celcius
(The lower the temperature the greater the efficiency)
Conclusion:
Item only delivers 82% of its described wattage (P=U*I=8.28W).
(Note that a PWM DC converter brings the wattage down by another factor of about 0.85 or in the case of a MPPT converter 0.95. A MPPT converter is better, but a bit more expensive and there a lot of fake ones).
