Technically, all you need to charge a 12v battery is a solar panel with a 12v rating. This can be any solar panel, although the bigger it's, the quicker your battery will charge.
Key specifications to consider when evaluating solar panels are the wattage or power rating, efficiency percentage, operating voltage, current output, and the temperature coefficient that indicates how the panel's performance is affected by temperature changes.
I've tested dozens of models from top brands like Bluetti, Jackery, Anker, Goal Zero, EcoFlow, and BioLite, and have come away impressed with their power generation potential.
This guide walks you through everything you need to know about non-standard solar panel design. You'll learn what's possible, what affects performance, how much customization costs, and how to specify exactly what you need.
