The laptop would most likely charge from the 16v setting on the v60 and the 9v battery from the 12v source.
How does a solar panel charge a battery.
It safeguards the deep cycle batteries from being overcharged during the day.
This means that on that scenario the solar panel delivered 60 watts of power to charge the battery.
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.
In general we recommend using the panels to charge our v60 battery and then set the output on the battery to charge your devices.
For an effective charge you need to make sure that the panel is directly facing the sun and no obstacles in between.
How to charge 12 volt battery with solar panel.
To charge a battery with a solar panel connect a charge connector to the solar panel.
Divide the wattage of the solar panel by the voltage of the battery to get the number of amps your charge connector needs to handle.
When sunlight shines directs on a panel the charging speed gets a boost and charging cycles slow down on a cloudy day.
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.
If a battery is totally drained a solar panel can energize the cells within five to eight hours.
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.
The position of the sun in the sky can impact a panel s charging speed.
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.
