With the deepening of the "double carbon" strategy, the revitalization of smart cities and rural areas continues to accelerate, and the outdoor lighting field is welcoming a green change. The traditional spotlight, which used to rely on the power grid and had high energy consumption, is gradually being replaced by more environmentally-friendly, efficient and flexible solar projection products. The industry is facing explosive development opportunities, and green, efficient, intelligent and scene-oriented has become the core development direction.

The continuous release of policy dividends has injected strong impetus into the development of solar energy projection industry. The Ministry of Ecology and Environment's "peak carbon dioxide emissions Implementation Plan for Urban and Rural Construction" clearly requires that in 2025, the photovoltaic coverage rate of new public institutions' buildings and workshops will reach 50%, and the penetration rate of solar lighting systems in the industrial and commercial fields will be increased to 38%; The Action Plan for Innovation and Development of Smart Photovoltaic Industry (2025-2030) further includes outdoor smart lighting in key development areas, and it is clear that the photovoltaic coverage rate of new public lighting facilities will reach 60% in 2027 and achieve full coverage in 2030. At the same time, under the rural revitalization strategy, the rural road lighting renovation project has covered more than 280,000 administrative villages, and the construction of smart cities has promoted the intelligent upgrading of landscape lighting, which together contributed about 55% of the market increase. According to the forecast of the National Renewable Energy Center, the market scale of solar floodlights in China will exceed 12 billion yuan in 2025, and it is expected to exceed 20 billion yuan in 2030, and the compound annual growth rate will remain high.

Iterative upgrading of technology is the core competitiveness of solar projection products based on the market. In recent years, the three core technologies of photovoltaic module, energy storage battery and intelligent control have achieved double breakthroughs, completely getting rid of the old label of "insufficient brightness, unstable battery life and easy damage" of solar projection lights. In terms of photovoltaic modules, the photoelectric conversion efficiency of monocrystalline silicon modules has exceeded 23.5%. With the technical breakthrough of increasing the energy density of lithium iron phosphate batteries to 180Wh/kg, the comprehensive energy efficiency ratio of the system has been improved by more than 40%, and the construction cost per tile has been reduced to 2.1 yuan /W, realizing "low power can have bright battery life" and stable lighting even in rainy days. In terms of durability, the split design is matched with ABS engineering material shell and explosion-proof toughened glass mask, so that the waterproof, rain-proof, lightning-proof and sun-proof performance of the product can be fully upgraded, the protection level can reach IP68, it can adapt to the extreme environment from -40℃ to 65℃, and its service life can be extended to 8-10 years, which perfectly adapts to complex outdoor scenes such as rural areas, mining areas and ports.

Intelligent fusion and scene subdivision further expand the application boundary of solar light projection. Nowadays, the solar spotlight is no longer a simple "lighting tool", but an intelligent terminal with "intelligent control and remote operation and maintenance". Products with intelligent light control, time control and remote control functions have become the mainstream, and the brightness can be adjusted remotely, the switching time can be set, and even the automatic alarm and remote diagnosis of faults can be realized, which greatly reduces the operation and maintenance cost. It is predicted by the industry that by 2030, the proportion of smart solar spotlights with remote control and fault diagnosis functions will exceed 70%. At the same time, the integrated optical storage and charging solution began to be applied in industrial parks on a large scale, realizing the multi-purpose of "lighting+energy storage+charging". It is estimated that the related derivative market will reach 8.5 billion yuan in 2030.

In terms of application scenarios, solar lighting has extended from traditional roads and courtyards to industrial parks, mining areas, ports, commercial complexes and other fields, and scene customization has become a new trend in the industry. For example, the solar-related lighting project recently put into use in Zhangjiagang Free Trade Zone adopts high-quality materials to adapt to the highly corrosive coastal environment, which is both energy-saving and beautiful, and has been highly recognized by the project party; In rural reconstruction and event lighting projects in Henan, Guizhou and other places, solar floodlights have effectively solved the pain point of outdoor lighting with the advantages of no wiring, zero electricity fee and convenient installation. Based on the advantages of original production, many enterprises can customize products with different power, brightness and installation methods according to different scene requirements, and provide one-stop service from scheme design to after-sales maintenance.

According to industry insiders, although the current solar energy projection industry has ushered in rapid development, it still faces problems such as low-cost involution, virtual parameters and uneven quality control. In the future, with the continuous development of policies and technology, the industry will gradually move towards standardization and high-quality development. As a green and low-carbon outdoor lighting solution, solar energy projection will play a more important role in the construction of a new energy system and inject new kinetic energy into urban green development and rural revitalization.
