How many solar panel required to charge 150ah battery?

Answered by admin @ 06/08/2021

Hi,

I’ll presuppose: 80% solar efficiency, 12V lead acid battery, solar charge controller (for more fun use MPPTs)

First, to correctly charging a 12V, 150Ah lead battery we need max 10% input current from 150Ah capacity, meaning max 15A.

In 5 h with 15A available you will get from 50% to 99.9% with a brand new battery.
In 5 h with 10A available you will get from 66% to 99.9% with a brand new battery.
In 5 h with 5A available you will get from 84% to 99.9% with a brand new battery.

Second, with a top notch MPPT 20A solar controller your answer is:
1x270W STC solar panel, preferably sun-oriented...

Hope it helps u.... :))
Plz mark it as brainliest.... ;))
