Start-up stage: Technology exploration and R&D: During this period, solar cell technology was in the early exploration stage. Some companies began to invest in R&D, trying to find more efficient and stable solar cell materials and manufacturing processes. For example, some companies and research institutions in the United States took the lead in conducting relevant research. For example, Hoffman Electronics achieved 10% efficient commercial photovoltaic cells in 1959, which was an important breakthrough at the time. Market cultivation: Due to the very high cost and relatively low efficiency of solar panels, market demand mainly comes from some special fields, such as aerospace. For example, in 1964, NASA launched the first Nimbus spacecraft powered by a 470-watt photovoltaic array. At this stage, solar panel equipment companies mainly provide customized products for these special customers, and the market size is very small.

Slow development stage: Technology improvement: With the continuous development of material science and electronic technology, the efficiency of solar cells has gradually increased and the cost has also decreased. For example, the continuous improvement of polycrystalline silicon and monocrystalline silicon cell technology has improved the performance of solar panels to a certain extent. Some companies have begun to focus on improving the conversion efficiency of solar panels, and achieve this goal by improving production processes and material formulations. Market expansion: Solar panels have begun to be used in communication base stations, lighthouses and other places in some remote areas, and market demand has gradually expanded. At the same time, some European countries and Japan have begun to introduce policies to support solar power generation, which has also provided certain opportunities for the development of solar panel equipment companies. Some companies have begun to try to enter the international market and establish cooperative relationships with foreign customers.

Rapid development stage: Policy promotion: Countries around the world are paying more and more attention to clean energy and have introduced policies to support the development of the solar power industry. For example, Germany took the lead in launching photovoltaic incentive policies in 2004. China also began to vigorously support the development of the photovoltaic industry during this period and introduced a series of subsidy policies and industrial plans. This has caused the market demand for solar panels to grow rapidly, and solar panel equipment companies have ushered in opportunities for rapid development. Technological innovation: During this period, solar panel equipment companies have made significant progress in technological innovation. For example, thin-film solar cell technology has gradually matured, has advantages such as low cost and flexibility, and has begun to be applied in some specific fields. At the same time, the efficiency of crystalline silicon solar cells continues to improve and the cost continues to decrease, making solar panels increasingly more cost-effective. Industrial integration: With the growth of market demand, competition in the solar panel equipment industry has become increasingly fierce. Some large companies have integrated their industrial chains through mergers, acquisitions, reorganizations, etc. to improve their competitiveness. For example, some companies not only produce solar panels, but are also involved in upstream silicon material production and downstream photovoltaic power station construction, forming a complete industrial chain.

Stable development stage: Market maturity: After years of development, the solar panel market has gradually matured, and the growth rate of market demand has stabilized. Photovoltaic power generation in various countries has gradually achieved grid parity, and the industry has reversed from the past subsidy thinking to market-oriented profit thinking. Solar panel equipment companies need to continuously improve product quality and service levels to meet customer needs. Technology upgrade: With the development of technologies such as artificial intelligence and big data, solar panel equipment companies have begun to apply these technologies to the production process to improve production efficiency and product quality. For example, through intelligent production equipment and management systems, precise control and optimization of the production process can be achieved. At the same time, new solar cell technologies such as perovskite solar cells continue to emerge, and some companies have begun to increase their investment in the research and development of these new technologies to lay the foundation for future development. Global competition: In the context of globalization, solar panel equipment companies face competition from all over the world. Some Chinese solar panel equipment companies have occupied an important position in the international market with their cost advantages and technological advantages. At the same time, some large international companies have also continuously increased their investment in the Chinese market, and market competition is becoming increasingly fierce.
