I will also share a few tips you need to know along the way.
Can you charge 24v battery with 12v solar panel.
So just use the solar to charge the 12v battery instead of charging 24v and then use a boost converter to power the rest.
Let s say you want to compute for the average charging time of a system with a 12v battery with 50 ah capacity and a 15 watts solar panel.
Connect battery to charge controller.
If it is 72 cells and voc of around 44v then it is a 24v solar panel and can charge a 24v battery.
An important point to be noted here is that a 24v rating battery is not available in the market but you can create one by joining two 12v batteries in a series connection.

These panels are great for charging your 12 or 24 volt batteries.
Solar panels are ideal for use in off grid applications.
However since you have 12v loads it makes sense to have a 12v battery bank with the 2 batteries wired in parallel.
In this article i will explain how to connect a solar panel to a battery step by step.
The first thing you have to do it to compute for the ampere rating of the solar panel by following the equation below.
I could use a zener diode or 7612 to keep the solar charge voltage at 12v constant unless sun is down.
