If you are connecting to an off the shelf battery pack there are a number of reasons that the charge rate could be worse.

Calculate recharge rate with 100 watt solar panel.

But clearly a 200 watt solar panel can charge at a rate of roughly 15 17 amps per hour. Most crucially 100 watt solar panels provide you less bang for buck i e. Solar panels usually range in wattage output from around 250 watts to 400 watts but some panels exceed the 400 watt mark. Amps 16 2 3 amps.

This means that on that scenario the solar panel delivered 60 watts of power to charge the battery. You can get the amount of energy it will provide the battery by multiplying 10 watts by 6 hours which will give you 60 wh. 6 watt solar panel charging a 4 000mah 3 7v battery time 14 8wh 6 watts x 2 4 9 hours. You get less watt per dollar when compared to larger panels.

200 watts 12 volts x. Get a usb multimeter from amazon to verify your charge rate. So solar panel must be rated at 10 amps so that at peak sunlight it gives 10 amps and gradually becomes lower until it drops at 2 amps by evening. 8 76 kw grid tied solar system with solaredge and 24 astronergy solar 365 watt panels wss solaredge gridtie system for 24 astronergy 72 cell modules 12 406 00.

If your system is 12 volts nominal this is what i recommend you do. Again assuming a fully depleted battery you would need 20 amps average charging current 100 ah 5 hours. The solar panel with the highest watt is the sunpower e series a commercial solar panel line. Or you can use a 12 x 5 60 watt panel if you can keep its direction continuously angled towards the sun.

All of these factors mean that a home solar system built with 100 watt solar panels simply isn t worth it. So if you have a solar panel that with a 10 watts power rating and it is exposed to sunlight for at least 6 hours. Amps 200 watts 12 volts. Solar pcu is a device through which you can directly connect your solar panel and your battery charging will start without any solar charge controller because it has a inbuild charge controller.

The top panel in the e series comes out at a whopping 435 watts. And if you want to continue with your existing inverter then you can buy smarten 24v 50amp. For example if the solar panel is rated at 175 watts and the maximum power voltage vmp is given as 23 6 volts then calculate the current as 175 watts divided by 23 6 volts which is equal to 7. Say you use a 200 watt solar panel.
