Hello all .
Do you like to open a conversation about solar and wind energy ?
I found out it, for to have free power for a laptop 24/24 at day.

But i saw the cost is very high : 2 solar panels total 160 watts ,batterie one 200 mAh ,inverter 12 volt -220 volt ac 300 watts ,and one regulator charge ,total cost here to Greece 1100-1300 euro

for to have 60-70 watts 24 hours a day .
