What size battery you need, will depend on the total power production of your solar panels. And the power output of the solar panels will depend on how many peak sun hoursyour location receives. Which I'll explain in a moment. Generally, for a 200 watt solar panel, you need 12v 100Ah. .
You might be wondering, which type of battery you should go for. Here are some key points that will help to make the decision easy for you. .
You need batteries to store the DC power output from solar panels or later use or in case of an emergency. But, for a 200w solar panel system, I would recommend buying a portable solar power station. Especially, if you need power on the go. Which is easy. When using a solar panel 200 watt 12 volt, the perfect match of battery you can use is a 12-volt 40Ah 500-watt-hours battery. That said, when it comes to the number of battery storage for your requirements, you need to determine your power consumption, which is gauged in kWh. [pdf]
