Hello,
I was looking for garden light for my mom's house. I found this product. http://www.brightnightsolar.com/list...i-solar-light/
they are energize 30 watt led with 22.7 solar panel and 3.7 volt 39 Ah Li-ion battery according to data sheet. Is it posibble?
According to my calculation:
consumption: 30 watt x 11 hours x 1.5 (for mppt) = 495 watt.hour
size of solar panel: 666 watt.hour / 3.8 lowest sun hours = 130 watt solar module
size of battery: 495 /( 0.5 x 0.85 x 12 volt) = 97 Ah minimum
size of charge controller = 130 watt / 12 volt = 10.83 amp
my calculations are correct ?
Thank you
