Operating the 125 watt solar panel

To get the 125 watt solar module in operation we must have  controller,  inverter 

 and battery. 

Size the charge controller by dividing max  watts into total volts.

This is 125/12 = 10.4 Ampere

Add 25% to be safe and you have a 13 Ampere charger.

A twenty  Amp charge controller will work well.

Size the battery;  Divide total watts into the volts.

Use a 110 Ah battery.

To size the inverter by deciding the maximum watts you will use at a specific instance in time.

The max output watts is  125. 

Use an  inverter between one and a quarter and one and a half times more than max output.

We can choose a 250 watt inverter. It gives a very flexible system.


  • The 125 watt solar module is easy to customize.

  • The pre-drilled holes in the frame make it easy to mount on a variety of ground support or solar pole structures.
  • The polycrystalline module is efficient. It produces reasonable output in lower light conditions.
  • The modules are reliable with a long lifespan.

  • It comes with an anodized aluminum alloy frame. The frame is sturdy. It has high corrosion resistance with high strength and durability.
  • They seal the module with low iron high transmission tempered glass 3, 2 mm thick. It is impact resistant and the light transmission is of very high quality.
  • The 125 watt solar panel has a weather proof junction box. It allows for connection with a waterproof strain relief connector. 
  • This ensures easy connection to a charge controller.
  • Performance and reliability are far above the average in this field..
