Now, green and energy-saving are the main themes of development. Energy has always been an important source of empowerment for social development. At the same time, green, and environmentally friendly clean energy is gradually infiltrating into social life. Various industries are also seeking new development paths that integrate with photovoltaic technology. According to data from the National Energy Administration, as of the end of April this year, China's installed capacity of solar power generation is about 440 million kilowatts, a year-on-year increase of 36.6%. Experts predict that in 2023, China's cumulative installed capacity of photovoltaic power will surpass that of hydro-power for the first time, becoming the first non-fossil energy source of power generation.
The Ministry of Housing and Urban Rural Development approved the "General Specification for Building Energy Conservation and Renewable Energy Utilization" and implemented it from April 1, 2022. Solar roof tile is an important energy-saving building system and is expected to become the preferred choice for renewable energy systems under the requirements of the new regulations. The new regulations require that new buildings should be equipped with solar energy power and retrofit solar energy systems on existing buildings. In addition, the document "Action Plan for Carbon Peak before 2030" requires that by 2025, the photovoltaic coverage rate on the roofs of new public institution buildings and new factory buildings should strive to reach 50%. This has prompted photovoltaic buildings to further open up the market.
Under the energy crisis, European electricity prices were out of control, with the highest price exceeding ten times the previous level. Before 2021, electricity prices in European countries were generally stable at 40-50 euros/MWh. In 2022, gas prices surged, leading to three increases in electricity prices. At the same time, the proportion of carbon prices in coal and gas power generation costs decreased, and the impact on electricity prices weakened. From July 10th to 21st, 2022, the Beixi pipeline underwent maintenance. In August, after a brief resumption of gas supply, Beixi stopped gas indefinitely again. At this time, multiple problems such as Russia's gas supply interruption, low gas storage rate, and winter demand growth were concentrated, resulting in electricity prices hitting new highs. Countries with natural gas as their main power source, such as Italy Dali and the Netherlands, have seen the highest electricity price increases, rising nearly ten times from previous levels.
Sangobuild innovatively designs crystalline silicon photovoltaic technology and roof tile structures, producing solar roof tiles that integrate photovoltaic and building properties. This not only replaces cement and traditional roof tiles, but also provides a continuous source of green energy for buildings.
