For an effective charge you need to make sure that the panel is directly facing the sun and no obstacles in between.
I am looking to mount one or two solar panels on my cargo bike long john for bicycle touring.
Then take the battery capacity which measured in ah and divide it by the amp rating the result from prior computation of the solar panel and then adding 10 of the charging time to it.
Then run wires from the battery to the charge connector making sure to match the positive and negative poles.
Can a 200 watt solar panel charge a 100 amper hour deep cycle battery short answer.
To charge a battery with a solar panel connect a charge connector to the solar panel.
Accepted practice is to.
Typically in direct unobstructed sunlight you should allow up to 50 hours to charge the battery on a standard 25 000mah power bank fully.
Now on the voltage of the panel you need a panel capable of up to 14 5 volts to fully charge the battery even when it starts charging at.
Any rating of solar panel can charge the battery the panel only has to be at higher voltage than your battery which can be tricky.
I ll assume that you are asking.
As such i wonder if i can charge my thinkpad it has a 20v input but the battery itself is a mere 10 8v 7 8ah with one or two of your panels and how i would go about setting it up.
