Policy Research Observation | Photovoltaic + Building: Jointly Painting a New Green Picture

Energy issues and environmental protection are currently the focus of global attention. Recently, Guangdong and other places have actively deployed and promoted pilot projects for county-level "photovoltaic + building" applications. The perfect combination of photovoltaics and buildings, like a magnificent picture, is slowly unfolding, outlining a sustainable green future. "The river flowers are redder than fire at sunrise, and the river water is as green as blue in spring." When people look up at the blue sky and bathe in the warm sunshine, they can't help but marvel at the endless treasures bestowed by nature. Solar energy, as a clean and renewable energy source, is changing people's lives with its unique charm. The integration of photovoltaics and buildings is like a beautiful encounter, perfectly combining technology and art, environmental protection and practicality.

Building-integrated photovoltaics (BIPV) involves installing solar photovoltaic arrays on the exterior surfaces of a building's envelope to provide electricity. This innovative design concept not only achieves self-sufficient energy supply for buildings but also reduces reliance on traditional energy sources, lowers carbon emissions, and makes a positive contribution to environmental protection. "The lotus leaves are infinitely green, and the lotus flowers are exceptionally red in the sun." Photovoltaic panels, like lotus leaves, cover the roofs and walls of buildings, absorbing solar energy and converting it into clean electricity, injecting green vitality into the buildings.

In terms of aesthetics, photovoltaic buildings are uniquely charming. The color and shape of the photovoltaic panels can be customized according to the design needs of the building, complementing the overall style of the building. Whether minimalist and modern or simple and elegant, photovoltaic buildings can complement modern high-rise buildings and add a touch of fashion to traditional buildings. "If I were to compare West Lake to Xizi, light or heavy makeup would suit her." Whether it's a city skyscraper or a quiet country cottage, photovoltaic buildings can showcase different styles in different environments. They can become iconic city buildings or blend into the natural scenery of the countryside, adding a touch of brilliance to the earth.

In terms of functionality, photovoltaic buildings demonstrate excellence. First, the solar photovoltaic power generation system can provide buildings with a clean and stable power supply to meet the operational needs of equipment such as lighting, air conditioning, and elevators. During the day, photovoltaic panels absorb solar energy and convert it into electricity for storage; at night or on cloudy and rainy days, the stored electricity can continue to power the building, achieving energy self-sufficiency. "Stealthily entering the night with the wind, moisturizing things silently." Photovoltaic buildings are like silent guardians, providing people with a comfortable living environment without producing any noise or pollution. Second, photovoltaic buildings have good heat insulation performance. Photovoltaic panels can block some solar radiation, reducing the increase in indoor temperature and lowering the air conditioning load. In winter, photovoltaic panels can also provide a certain degree of insulation, reducing heat loss. "Plum blossoms must yield to snow in whiteness, but snow yields to plum blossoms in fragrance." Compared with traditional buildings, photovoltaic buildings have unique advantages in terms of heat insulation. They can save energy and improve indoor comfort, bringing people a healthier and more comfortable living experience.

The combination of photovoltaics and buildings not only brings practical economic benefits but also has profound social significance. On the one hand, photovoltaic buildings can reduce the operating costs of buildings and improve energy efficiency. Through solar photovoltaic power generation, buildings can reduce their reliance on the traditional power grid and lower electricity costs. At the same time, photovoltaic buildings can also enjoy government subsidies and preferential policies, further improving economic efficiency. "Spring sowing of a grain of millet, autumn harvest of ten thousand grains." Photovoltaic buildings are like seeds of hope, sown on the earth, bringing people the joy of harvest. On the other hand, the promotion and application of photovoltaic buildings can promote the development of renewable energy and drive the adjustment of the energy structure. With the increasing global emphasis on environmental protection and the growing demand for renewable energy, photovoltaic buildings, as a green and environmentally friendly building form, will play an increasingly important role. It can provide people with a comfortable and healthy living environment, and also leave a clear sky and blue water for future generations. It can provide reference for renewable energy applications in other fields, driving the entire society towards a green and low-carbon direction. "Thousands of sails pass by the sunken boat, and ten thousand trees spring up before the diseased tree." In the wave of energy revolution, photovoltaic buildings are leading the future development direction of buildings with their vigorous vitality.

The integration of photovoltaics and buildings is not without its challenges; some issues need to be addressed in practical applications. In terms of technology, the efficiency and lifespan of photovoltaic panels need to be improved, and the stability and reliability of photovoltaic systems need to be further enhanced. In terms of cost, the initial investment of photovoltaic buildings is relatively high, which to some extent limits their large-scale promotion and application. With continuous technological advancements and policy improvements, these issues will gradually be resolved. "There will be times when the strong wind breaks the waves, and the sails will be hoisted to cross the ocean." On the path of future development, photovoltaic buildings will usher in a broader development prospect.
