Customer ServiceLet’s look at how to choose the battery for a solar panel. A good general rule of thumb for most applications is a 1:1 ratio of batteries and watts, or slightly more if you live near the poles.
But before doing this, one has to understand the basics of battery Voltage matching with the Solar Panel Voltages. As Solar panels are being made for higher wattages, the solar panel voltage is also increasing as the number of cells increases in any given Solar Panel.
The appropriate solar charge controller does the matching. There ARE boosting ones (for battery V > solar V), but rare and expensive last time I looked, unless you build your own. Just FYI if your solar panel is rated at 100W, you can usually look up the actual output voltage and current at that power rating for your panel.
I read somewhere that the solar panel should have a 40% to 80% higher voltage than the battery. That means that a 12V battery pack should be logical. And in between the solar panels and the battery pack we'll put an MPPT charge controller. My question is; does all this make sense?
A solar panel is a constant-current source, not a constant-voltage source. The voltage indicated in the specifications are therefore only (more-or-less) the maximum and rather irrelevant. What you need is a charge controller that matches your battery voltage (12V in that case), the rest is regulated by that controller.
You can charge a 12V battery with 50V PV while keeping the PV voltage at the maximum power point. There are some boost MPPTs that can charge batteries at higher voltages than the PV but they don't seem to be the norm and you have to check to make sure this feature is on the charge controller you choose if you want to go that way.
