Currently, global warming continues to intensify, prompting countries around the world to increasingly prioritize and deeply discuss this issue. There is a strong push toward vigorously developing renewable energy sources and eco-friendly products, with solar power generation occupying a particularly important position. This distributed photovoltaic power generation approach not only provides green electricity for businesses but also significantly reduces emissions of various pollutants. As a result, it serves as a model for accelerating the launch of China's chemical industry in the PV market and for optimizing the structure of energy production and consumption.

　　A rooftop photovoltaic power station is a distributed generation system that uses photovoltaic modules to directly convert solar energy into electricity. It represents a new, innovative approach to power generation and comprehensive energy utilization, with vast potential for future development. The benefits of generating electricity from solar energy include: first, on-site consumption of power, ensuring full utilization of the generated electricity; second, eliminating the need for long-distance transmission, thereby significantly reducing investment costs and minimizing transmission losses; third, decentralized power sources that connect to the grid at very low voltage levels; and fourth, minimal environmental impact—this method produces no air or water pollution, delivering outstanding eco-friendly advantages. In many European and American countries, the model of decentralized development combined with local power supply has already gained widespread acceptance among both households and businesses.

　　Chemical enterprises are major energy consumers. For some chemical projects that require relatively low electricity usage, leveraging underutilized rooftop resources to build photovoltaic solar power plants could be a viable option. This approach offers advantages such as efficient energy utilization, minimal energy loss, reduced pollution, and flexible operation—while also delivering significant economic, energy-saving, and emission-reduction benefits.

　　To encourage the development of new energy sources such as solar power, State Grid Corporation issued the "Opinions on Doing a Good Job in Grid Connection Services for Distributed Power Sources" in February 2013, clearly stating its commitment to creating a streamlined pathway for distributed energy and providing a range of free grid connection services. Hopefully, as policies, technologies, and markets continue to mature, more chemical enterprises will soon adopt distributed photovoltaic power generation.
