What is the proportion of material cost to total production cost for commercial solar panels?
The proportion of materials cost to total production cost for commercial solar panels may vary from different manufacturers, but it should be controlled within a certain range. The material cost includes the direct materials consumed in the manufacturing process, auxiliary materials, purchased semi-finished products, and others. Generally, the material cost should account for 1/3 or 1/4 of the total cost because the quality of the materials determines the quality of the finished products to some extent, and to get high-quality and certified products, it requires a company adhering to integrity and honesty to put a certain amount of investment in purchasing reliable raw materials.
