60 watt solar led street light solar knowledge:

The use of quality solar cell materials is the ultimate solution to reduce the cost of materials and products. In the thin system, a thin film solar cell is prepared by depositing a battery material on a glass or a substrate made of Kang price by using techniques such as sputtering, vacuum evaporation, and CVD. The CIGS solar cell is produced by a method of preparing a metal alloy film on a glass of a priced glass in a vacuum chamber, thereby achieving cost reduction. In both the thin film silicon system and the C1GS system, high speed preparation can be carried out on the film substrate by the double wave method (Fig. 3). In order to realize the preparation of solar cell thin films at a lower cost in the future, various new methods such as coating methods and electrical practices are being studied.

The production cost of batteries, components, etc., will gradually decrease as the scale of production increases. In addition, reducing the use of transparent conductive and rare metals in the wiring can also effectively reduce costs.
