Battery Capacity (in Watt hours) X 2 / Rated Panel Power (in Watts) Example: 10 Watt, 18 Volt Solar Panel charging a 12V, 10 Amp hour Lead Acid Battery (120Wh) from 50% full to Full – Time = 60Wh x 2 / 10 Watts = 12 hours The solar charge times above assume a 25 degree Celsius day with the panel pointed directly at the sun.
Example: 10 Watt, 18 Volt Solar Panel charging a 12V, 10 Amp hour Lead Acid Battery (120Wh) from 50% full to Full – Time = 60Wh x 2 / 10 Watts = 12 hours The solar charge times above assume a 25 degree Celsius day with the panel pointed directly at the sun. Some quick rules for estimation:
Example: 6 Watt Solar Panel charging a 4,000mAh, 3.7V Battery – Time = 14.8Wh / 6 Watts X 2 = 4.9 hours Tip: Get a “ USB Multimeter ” from Amazon to verify your charge rate. If you are connecting to an off the shelf battery pack, there are a number of reasons that the charge rate could be worse.
Output power (W) = total watts (W) x conversion efficiency of the solar system x (1 – charge controller’s power consumption rate) Substitute the data to get the output power of your solar panel is 1615W, and then finally divide the solar battery charge by the output power of the solar panel to get the charging time, i.e.:
