What are the ways to judge the quality of solar panels?

Solar panel, also known as photovoltaic panel, is a medium that converts light energy into electrical energy and is one of the important components of solar street lights. Its application fields are very wide, not only used in road lighting, but also widely used in photovoltaic power generation projects. The quality of solar panels directly affects its power generation efficiency. Now that the market is becoming more and more competitive, more and more manufacturers are producing solar panels. Many manufacturers mix inferior products under the guise of low-price promotions in order to obtain greater profits. Therefore, we must master the method when we choose, and avoid buying poor-quality solar panels. The following lighting will tell you how to judge the quality of solar panels.

.The level of silicon wafers in the solar panel.

A-level wafers are the silicon wafers with the highest conversion rate. A-level wafers have better appearance than B-level wafers. B-level wafers may appear to be slicked. Of course, B-level wafers are still the mainstream in the market now, and B-level wafers There are also good quality.

.Look at the surface

Look at whether there is silica gel on the tempered glass of the solar panel. Some small manufacturers are pursuing the speed of production and often drop the silica gel on the tempered glass inadvertently. If there is silica gel, it will affect the power generation efficiency of the solar panel. If it has been found, it must be cleared in time.

.Look at the cell splicing

In order to gain profits, many manufacturers splice the damaged cells together, and no traces can be seen on the surface. However, long-term use may cause the cell panels to rupture and affect the overall power generation efficiency. In severe cases, the battery may be caused by high summer temperatures. Spontaneous combustion!

.Look at silica gel

Check whether the silica gel on the four sides is even and whether it penetrates.

.Look at the border

See if the strength of the frame is even and the tightness is different.

.Look at welding

Observe whether there is any missing solder. See if the cell is regular.

.Look at the junction box

Whether it is close, choose to transfer freely.

The quality of solar panels is directly related to the overall performance and use effect of solar street lights, so when we buy solar panels, we must carefully judge and purchase according to the above methods. It will be safer and more assured to use in this way.
