How much watts of solar panel need to charge 70Ah battery?
You would need a solar panel that can output at least 50watt with 13.5 volt to charge 70Ah battery. Low watts for a very time will still do the job but it will take more sun hours.
There will be no charging at all if the volts are lower than the battery voltage.
What size solar panel to charge 70ah battery?
A 50 Watt solar panel size 22.9 x 20.0 x 1.18 inch 12 Volt can generate a maximum current of approximately 2.5-2.8A in direct sunlight can charge 70ah battery. However, it is wise to assume some energy losses in cables or solar controllers, as well as sun or weather conditions. Therefore the charging current for a leisure battery might be lower, about 2.0A each hour.
As a result, a 4 amps charge at 13.8 volts (50 watts) will take at least 18 hours to fully charge 70ah battery. A 50 watt single solar panel with the ability to deliver at least a voltage of 12 to 18 volts.
Can an 80 watt solar panel charge a 70Ahr battery in 5 hours?
An 80 Watt solar panel can optimally deliver 80 x 5 = 400Wh of energy in direct 5 sun hours. Typically that would be enough to fully charge a discharged 12 battery.
But A 12V battery would need 840Wh (12V x 70Ah) to charge a depleted battery. There are significant losses to take into account when charging a battery, and therefore you would need at least a 200W panel to charge a 12V, 70Ah battery in 5 hours.
