You can see the limitations of this solar panel, but it is still useful for small appliances, batteries and devices. It has no problems charging a 25ah battery for instance, and you can charge

You are placing the charging battery solar panel set up under perfect sunlight conditions. Then via MPPT solar panel charge converter, it will hardly take 5–6 hours to charge the battery properly. Whereas under the same conditions, the PWM charge controller would take 7–8 hours to charge the battery to its utmost level.
Number of solar panels x wattage of individual solar panels = total wattage of solar panels For example, assuming you have 20 units 200w solar panels in your solar system, according to the above formula, you can enter 4000 into the solar panel wattage column of the calculator. 2. Solar battery Capacity (Ah)
First up, solar panel wattage. Bigger wattage = more juice, faster charge. A 200W panel charges quicker than a 100W one, simple math. Then there's sunlight hours. Full sun? You’re golden.
Here’s the cheat code: Charging Time = Battery Capacity (Wh) ÷ Solar Panel Output (W) Start with your battery’s capacity in watt-hours (Wh). If it’s in amp-hours (Ah), just multiply by the voltage. Example: A 12V, 100Ah battery = 1200Wh. Next, look at your panel’s output in watts. But don’t just take the panel’s sticker number.
