1, why use a multimeter test current does not reach the nominal current?


A: Because the short-circuit current parameter is a measure of the quality of solar cells, this parameter only with the component tester can test it out, and load meter itself, so the current parameters of the test is working, do not misunderstand. And solar panel test conditions of 1000 W / m illumination 25 degrees Celsius AM1.5 (atmospheric transparency) Our solar panels are light intensity on standardized tests, are theoretical concepts, the solar panels will vary according to regional buyers, good or bad weather And the degree of pollution will be moderate decline.


2, solar panels can drive much power appliances?


A: It depends on the size and capacity of the battery power inverter customer terminal, which has nothing to do with our solar panels, solar panels we are only responsible for your battery charge, which itself does not store electricity, solar energy is responsible to the battery charge, Battery discharge to the electrical equipment, which is a charge and discharge process. Customers must understand some basic knowledge of the electrical system, so as to go back and do DIY, if these principles can not understand inquiries about more than Baidu, Taobao heart again and a framework concept, or it may be a waste of valuable time.


3, solar panels can use it?


A: The concept is very vague, cloudy depends on the intensity of light, if the light will have a weak current and voltage, but this and the sunny light than a few hundred to several hundred times! In short, the stronger the light, the better the power generation, the weaker the light, the worse the effect.


5, solar panels do not use the controller ok?


A: Yes to use the controller! Not the words, but also can, but it is to see how you use, the role of the controller is intelligent control of solar energy and battery and load the relationship between the protection of the battery to prevent overcharge and over discharge, short circuit protection, and intelligent control load work Time status, etc., refer to the controller manual. If you do not use the controller, there may be overcharge to the battery may be, this will damage the battery, while over the battery life will have an impact. In addition, the controller load on the current requirements, 10A controller generally its load does not exceed more than 12A of the current, if the protection is no output. Correspondingly, 10A can bring 120W the following appliances, 20A can bring 240W the following appliances, 30A can bring 360W the following electrical appliances. Buyers can choose their own.


[Single polycrystalline difference]

Single crystal panel relative conversion efficiency is higher, polycrystalline low light better, so single crystal in the sunny day when the conversion efficiency is higher, polycrystalline in the cloudy day when the performance is better. The price is slightly higher than the polycrystalline crystal, the current and voltage will be a single crystal is good.

First, the principle and composition of solar photovoltaic power supply system:
Solar cell power generation system is the use of photovoltaic effect of the principle of solar cells can be made of solar radiation can be directly converted into electrical power generation system. It consists of solar cell matrix, controller, battery, DC / AC inverter and other components, the system composition shown in the figure.
1 · Solar panels:

The core part of the solar power system is also part of the value comparison of solar power generation systems.

The role is to convert solar energy into electricity, or sent to the battery stored, or to promote the load work.

2. Solar controller:
The role is to control the working state of the entire system, and the battery played a charge protection, over discharge protection role.

3 · Battery:
Its role is in the light when the solar panels issued by the energy stored in the need to release when needed.

4 · Inverter:
As the direct output of solar energy is generally direct current, in order to be able to AC220V electrical appliances to provide electricity, the need for solar power generation system issued by the DC power into AC power, so the need to use DC-AC inverter.


The use of time must be 12 o'clock in the direction of the sun facing the battery panel and the ground was 30 - 45 degrees angle, should not be the board square on the ground, so that the power generation is very low
