I would like to know if that size panel could power a small MP3 player? Could it power a laptop?
I doubt it!
I have a portable 240watt Monocrystalline Solar panel thath I run an 32" LCD TV, Notebook, 80 LItre Fridge Freezer and battery chargers, phones and a
few other rechargable devices.
To run this I have a 120ah Deep Cycle Battery with a 3000 watt pure sine wave inverter - I've been told not to go for a modified sine...
Expensive set up but worth it - All I need is a big "h" to go on top of my tent - "h" is for Hilton...
Avoid car batteries as they are designed for a short sharp high burst of energy as apposed to a deep cycle that is designed to run these types of
things for longer periods and last alot longer as well. Never drain your battery by more than 50% as that will shorten their life. To get a meter to
measure battery power will set you back big bickies...
You could use a 40 watt panel to charge a laptop but its gonna take a while.
Calculate total Wh - Convert to Ah
Capacity Ah (Battery) = Power Consumption (Wh) / Total Battery Voltage = wh / (12 x Battery Voltage) = Ah Battery Required.
Hope this helps.
