To get the most effective charging by a solar panel you have to maximize the amount of current by keeping the board pointed directly to the sun.
How long to charge 1 2w mon solar panel batter.
The solar battery maintainer is not meant to charge 12v batteries it is designed to maintain an existing charge and offset the natural voltage loss of the battery.
10 watt 18 volt solar panel charging a 12v 10 amp hour lead acid battery 120 wh from 50 full to full time 60wh x 2 10 watts 12 hours.
In one week you want to run a 65w television for 4 hours and an 8w light for 5 hours.
How long does it take to charge a 12v battery.
So if you have a solar panel that with a 10 watts power rating and it is exposed to sunlight for at least 6 hours.
The short answer is in most cases depending on the size of the battery it will take around 5 8 hours to fully charge a 12 volt car battery with a solar panel that can produce 1 amp of current.
Eco worthy 100w 200w solar panel system kit for 12v battery power charge controller home rv.
Some correction i make to improve charging during winter solar cell should be 6 v and current or power can be variable like 500 mah or 1ah diode to protect tp4056 f.
Some quick rules for estimation.
You can get the amount of energy it will provide the battery by multiplying 10 watts by 6 hours which will give you 60 wh.
Then run wires from the battery to the charge connector making sure to match the positive and negative poles.
