Connection Mode

Arbitrarily change the output power and voltage through different connect ways in series or in parallel, to meet your needs!

Connection way:

The blue side connects “-” (negative), white side connect “+”(positive).

In order to ensure enough power, Suggest using solder strips or copper strips to connect.

Note:

1. Because the output power of solar panels depends on solar irradiance and solar panel temperature and other factors

Therefore, the measurement of solar panels needs under standard conditions (STC).

The standard conditions are defined as air quality AM1.5, light intensity 1000W/m2, and temperature 25′.

2. Under this condition, the maximum output power by the solar panel is called peak power.

In many cases, the peak power of the module is usually measured by a solar simulator.

The main factors affecting the output performance of the solar panel are as follows:

a. Load impedance

b. sunshine intensity

c. Temperature

d. Shadow

 

 

Attention

There may be some solar panels have a small spot on the side

Please don’t worry, it’s a normal phenomenon and will not affect the function of the solar panels

Please choose the cells carefully, it’s micro and super thin

The color is blue, because of Production process reasons, Unavoidable color
depth is different, some panels are deep, and some panels are pale.

But it has the same function. (you can see it in the following image)

On the use and testing:

The product can only be used in the sun, the nominal power is noon sun
peak, morning and evening sun and not strong sunlight is not up to the
nominal, which is the buyer’s attention!

And in the light Inside the room, the solar panel is almost impossible to detect what value!

This is ordinary light and the sun light caused by very different! So be sure to test under the great sun!
