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. You can use a single 100ah lithium-ion battery or two 100ah lead-acid batteries wired in parallel with a 200W solar panel. The best battery for a 200W solar panel would be a 100ah lithium-iron battery. Lithium-ion batteries would be superior in terms of lifespan and performance. [pdf]
