The world's photovoltaic power generation is developing rapidly. The output of photovoltaic cells continued to grow. The photovoltaic industry has been one of the fastest-growing and most stable fields in the world for many years. The production scale of photovoltaic cells continues to expand. The photovoltaic market is expanding rapidly.
Since 2000, the global photovoltaic industry has grown at a rate of 30%~~60% for 6 consecutive years. In 2002, the global output of photovoltaic cells was 560MW/a. By 2003, it had reached 750MW/a, an increase of 34%. Since 2004, Germany has revised the Renewable Energy Law. The new subsidy bill contributed to the subsequent outbreak of the German photovoltaic market. What followed was a new round of policy boom among developed countries and a faster expansion of the global photovoltaic market. With the globalization of the economy and the development of the world's population, more energy is required to meet the needs of economic and population development. However, the reserves of non-renewable energy sources such as oil and coal are declining, and new energy sources are still in the exploration stage. The oil crisis in 1973 and environmental pollution in the 1990s greatly promoted the development of solar photovoltaic power generation. With the continuous improvement of people's awareness of energy and environmental issues, photovoltaic power generation has received more and more attention from governments of all countries, and scientific research investment has been increasing. Policies to encourage and support the development of the photovoltaic industry are also constantly being introduced.
Photovoltaic power generation can provide energy. Solar photovoltaic has many special advantages, especially that it can supply power to remote areas and special occasions.
Distributed photovoltaic power generation has been used in home power supply, road lighting, landscape lighting, traffic monitoring, large billboards, power stations, etc. The market scale is gradually expanding, showing a broad market prospect. Solar photovoltaic lighting includes solar street lights, garden lights, lawn lights, solar landscape lighting, solar road signs and signs, signal instructions, advertising lightbox lighting, etc. There are also household lighting lamps and portable lamps, camping lamps, climbing lamps, fishing lamps, tapping lamps, energy-saving lamps, flashlights, and so on. The distributed photovoltaic power generation system represents the future development direction of photovoltaic power generation and has broad development prospects. It will become the most important application form in the development of new energy.
Taking into account the added value of solar photovoltaic, the comprehensive economic benefits of photovoltaic power generation have been greatly improved. Therefore, it is not possible to simply compare the unit power generation cost with the traditional power generation mode. Solar photovoltaic can reduce greenhouse gas and pollutant emissions, create employment opportunities, ensure energy security and promote the development of remote areas. In short, the development of solar photovoltaic has many positive economic, social and environmental protection significance.
The prospect of solar photovoltaic power generation is infinitely bright. New technologies continue to emerge, and battery efficiency continues to increase. Solar power generation is the cutting-edge technology in the world today. It will completely solve the three major world problems of "energy crisis", "environmental pollution" and "sustainable development" for all mankind. It will make a great historical and cross-generational contribution. Mankind has entered a brand-new era in the use of new energy and new technology, triggering a world scientific and technological revolution, and allowing all mankind to lead a healthy, happy and harmonious life.
