Now divide the battery capacity after DoD by the solar panel output (after taking into account the losses). Turns out, 100 watt solar panel will take about 9 peak sun hours to fully charge a 12v 100ah lead acid battery from 50% depth of discharge. how fast should you charge your battery?
The duration to charge a 12V battery with 300W solar panels depends on the battery capacity and the solar panel current. For instance, at 6 peak hours and 25% system losses (efficiency is 75%), a single 300W solar panel can fully charge a 12V 50Ah battery in roughly 10 hours and 40 minutes. Let’s understand it in detail,
The Battery Charging Time Calculator is a web-based tool that estimates how long it takes a solar panel to charge a battery completely. Users can enter the size of the solar panel (in watts), the size of the battery (in ampere-hours), the voltage of the battery, and the peak sun hours in their area into this calculator.
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.:
Assume you are using a 200W solar panel and an MPPT charge controller. Solar output = 200W ×— 95% = 190W 4. Divide the discharged battery capacity by the solar output to get your estimated charge time. Charge time = 960Wh ×· 190W = 5.1 hours
First of all, you need to start by converting the battery capacity of your solar battery from Ampere hours to Watt hours, ie: Watt-hours (Wh) = Amp-hours (Ah) x Voltage (V) Substituting the data gives you 960Wh for your solar battery. Then, you need to know how much you need to charge your solar battery, i.e.:
