Just hook up the panel with the battery and it can charge once the panel begins getting dazzling sunshine - offering the panel a voltage of minimum 30% to 50% more than battery power you might be charging. The voltage from the solar panel is not important and the voltage of the battery really does not make a difference.
To be able to control the voltage from the solar panel usually a voltage regulator circuit is employed relating to the solar panel output and the battery input. This circuit ensures that the voltage from the solar panel by no means surpasses the safe value needed by the battery for charging.
For any 12v 4.5AHr battery, the charging current is going to be 375mA for Half of the day and a bigger solar panel is going to be necessary. Some solar panels may discharge the battery (a touch) while it isn't obtaining sunlight and a diode is usually included with to protect against self discharge.
For this reason a 10 watt solar panel could be directly attached to a group of (practically fully discharged) 2,000mAhr cells. For a 12v 1.2AHr battery, the charging current is going to be 100mA for 12 hours or 330mA for 4 hours along with a regulator circuit is going to be necessary to protect against overcharging.
To avoid an excessive amount of mis-match, it is strongly recommended you keep the panel voltage to inside 150% of the battery voltage. (6v battery - 9v utmost solar panel, 12v battery - 18v optimum panel, 24v battery - 36v spork panel).
When the light hit them, they collectively produce voltage. Voltage production depends on environmental factors and various things. Anyway on average your panel would produce slightly half of your panel’s cell count. For example. You have your standard 32-Cell panel. It’ll be outputting 14V to 15V.
