  • Solar roof photovoltaic tiles: The green revolution for future building rooftops!
    In today's pursuit of sustainable development and environmental protection, new energy technologies are emerging like mushrooms after rain. Among them, "photovoltaic tiles" are a new type of building material that integrates efficient power generation and aesthetic design. They are quietly leading a green revolution on rooftops. Photovoltaic tiles, as the name suggests, combine photovoltaic power generation technology with traditional roof tiles. They not only fulfill the function of protecting buildings from wind and rain but also silently convert into clean electricity, providing continuous green energy for households and the entire society. Traditional roofing materials such as ceramic tiles and cement tiles, although having their own merits in durability and aesthetics, are less efficient in energy utilization. With the increasingly severe global climate change issues, reducing reliance on fossil fuels and promoting the use of renewable energy has become an international consensus. Photovoltaic technology, as an important form of solar energy utilization, its efficient and clean characteristics align with the integrated demand for buildings. Photovoltaic tiles emerged as a result. From an environmental perspective, the use of photovoltaic tiles significantly reduces carbon emissions. Once installed, it can continuously convert solar energy into electricity, reducing reliance on fossil fuels and contributing to the mitigation of global warming. For household users, the electricity generated by photovoltaic tiles can not only be self-sufficient but also the surplus electricity can be sold to power companies through the smart grid, achieving economic benefits. In the long run, the return on investment of photovoltaic tiles is quite considerable, especially with the support of government subsidies and tax incentives, its economic viability is even more prominent. Although photovoltaic tiles show great potential for development, their popularization path is not smooth. High initial costs, technological maturity.

  • Industrial and commercial photovoltaic solar shade | A green solution that combines aesthetics and practicality
    With the gradual promotion of the "green concept", energy-saving and consumption-reducing production methods have gradually gained popularity. Solar photovoltaic power generation, as an important part of the new energy field, is experiencing a golden period. Traditional photovoltaic technology has developed for nearly 10 years and has relatively high technical levels and market acceptance; however, it still falls short in terms of waterproof performance and aesthetic appeal.  Building-integrated photovoltaics (BIPV) is emerging as a new energy solution, gradually gaining popularity among the public. While emphasizing the high integration of photovoltaics with buildings, it also takes into account performance requirements such as waterproofing, fire resistance, wind resistance, and aesthetics. Industrial and commercial photovoltaic solar sheds, as a form of integrating photovoltaic power generation systems into buildings, are becoming a new choice for many enterprises and bringing new opportunities to the photovoltaic industry. I. Application Scenarios of Industrial and Commercial Photovoltaic Solar Sheds Industrial and commercial photovoltaic solar sheds refer to fully integrating photovoltaic power generation systems in the form of BIPV (building-integrated photovoltaics) into buildings to generate electricity. This form not only leaves more space while retaining the practical functions of traditional solar sheds, but also enables self-generation and self-consumption of electricity as well as grid-connected surplus power generation. It is environmentally friendly, aesthetically pleasing, and highly functional, truly achieving green and energy-efficient goals. Currently, the application scenarios of industrial and commercial photovoltaic solar sheds are diverse. Whether it is commercial buildings, industrial parks, or industrial plant roofs, as long as the lighting conditions are good and there is sufficient installation space, industrial and commercial photovoltaic solar sheds can be installed. At the same time, the appearance can be customized according to the individualized needs of the owners to meet multiple requirements. II. Market Analysis of Industrial and Commercial Photovoltaic Solar Sheds  With the increasing global demand for renewable energy and the support from countries for the new energy industry, the market for industrial and commercial photovoltaic solar sheds is expanding rapidly. At the same time, with the continuous advancement of technology, industrial and commercial photovoltaic solar sheds are being applied in more fields.  After calculation, based on the installation ratio of 30% for industrial, commercial and office building rooftops, and 50% for public building rooftops, the remaining installation space for rooftop photovoltaic systems on existing industrial and commercial flat roofs is approximately 262.74 GW. If the penetration rate of solar shade structures reaches 10%, the installed capacity of rooftop photovoltaic systems on industrial and commercial rooftops will reach 26.3 GW. If the penetration rate reaches 30%, the installed space will reach 78.9 GW.

  • The ultimate guide to the types of roofs suitable for installing household photovoltaic systems!
     What kind of roof is suitable for installing photovoltaic panels?  In China, the roofs of buildings are classified based on their appearance into two types: flat roofs and pitched roofs. Each type has its own advantages in terms of photovoltaic installation conditions.  The pitched roof has a large slope, which ensures smooth drainage during rainfalls. Moreover, its construction is simple and it is easy to maintain. Installing a photovoltaic power station on a pitched roof does not require the installation of supports; instead, the photovoltaic panels are laid according to the inclination angle of the roof. Since there is no need to consider the shading between the components, the components can completely cover the roof and are very aesthetically pleasing.  In China, pitched roofs are generally divided into single-pitched and double-pitched types. TCL Photovoltaic Technology has developed two household photovoltaic solutions, namely "Minghui Dian" and "Shuanghui Dian". Among them, "Minghui Dian" has strong power generation capacity and combines aesthetics with benefits; "Shuanghui Dian" can fully utilize the characteristics of double-pitched roofs and does not depend on the orientation of the roof, allowing users to enjoy double power generation benefits. In addition, if users want to use their own courtyard for photovoltaic power generation, they can adopt the "Huxue Yu" solution. The photovoltaic power station in the courtyard can be used as a car shelter, and chickens and vegetables can be raised under the photovoltaic panels, and one can receive "pension" while enjoying the sunshine. The special solution in the courtyard house - "Garden Truss House" is suitable for users who pursue maximum power generation benefits. In this solution, the photovoltaic panels cover the entire roof from the top to the courtyard, which not only increases the area of the photovoltaic components to improve power generation efficiency, but also provides shade for the courtyard and does not occupy the activity space of the courtyard. It can be said to achieve three benefits at once. To fully leverage the aesthetic advantages of pitched roof photovoltaic power stations, TCL Photovoltaic Technology has created the "Zero Carbon Villa" solution. Professional designers are responsible for the design of the power station, allowing the blue photovoltaic panels to perfectly blend with the roof, presenting a technological aesthetic with care. At the same time, "Zero Carbon Villa" is equipped with an energy storage system and charging piles, ensuring that the villa is self-sufficient in electricity, ensuring worry-free charging for the car, and creating a green, low-carbon, and intelligent high-quality life for villa owners. Flat roofs usually adopt the form of cement blocks + photovoltaic supports. The investment cost is not high, and the economic performance is relatively good. On flat roofs, the photovoltaic array can be installed at the optimal angle to maximize the power generation efficiency. Another advantage of installing a photovoltaic power station on a flat roof is that it can provide insulation and cooling for the house. The engineers of TCL Photovoltaic Technology once tested the cooling effect of photovoltaic roofs in Haikou, Hainan Province. The results showed that at 15 o'clock, the hottest time of the day, the temperature of the roof with the installed photovoltaic power station was on average about 6 degrees lower than that of the empty roof without installation.
