In 2017, home photovoltaics experienced explosive development, and the demand for crosslinking agent TAIC will also show a leap in growth. The quality of TAIC will also become increasingly strict, and various problems will gradually emerge with the hot market.
The structure of China's photovoltaic market is gradually shifting from ground power stations to distributed photovoltaic power generation, and chemical enterprises are also showing a reshuffle phenomenon. Similarly, the crosslinking agent TAIC used in photovoltaic grade will be gradually eliminated, and TAIC manufacturers with poor production quality will be phased out.

The structure of China's photovoltaic market is gradually shifting from ground power stations to distributed photovoltaic power generation, and chemical enterprises are also showing a reshuffle phenomenon. Similarly, the crosslinking agent TAIC used in photovoltaic grade will be gradually eliminated, and TAIC manufacturers with poor production quality will be phased out.
The home photovoltaic market is developing rapidly, but there is generally a lack of unified product quality standards and service standards. There are many participants in the home photovoltaic industry, especially numerous distributors and integrators emerging in various regions. The quality standard of photovoltaic TAIC is generally 99% or above.
A reporter from Energy magazine found in an interview that the home photovoltaic industry is currently uneven in quality, with a lack of technology and admission standards. Some distributors or integrators pass off inferior products as good, and their installation operations are not standardized. They take advantage of residents' lack of understanding of home photovoltaic installation and after-sales service, attract residents with low prices, and it is difficult to guarantee the quality and safety of power plants. At the same time, the "630" rush to install also lays hidden dangers for the quality of photovoltaic products and the industry.
At present, although there are some regulatory documents in some places, the actual strength is still limited, and phenomena such as vicious competition in the market have also occurred. The main battlefield of household photovoltaics is in rural areas, which mainly rely on "word of mouth" to establish a good brand reputation. Residents' lack of trust in household photovoltaics will severely impact the public opinion environment and social perception of the entire photovoltaic industry.
And the industry has also recognized this issue and begun to promote industry self-discipline. At the 2017 National Household Survey Report Conference and Household Photovoltaic Experience Exchange Conference, many enterprises reached a consensus on the development status of household photovoltaics, including establishing standards, strengthening self-discipline, avoiding price wars, and avoiding vicious competition. The industry generally believes that establishing a strong and implementable standard is also an effort that the home photovoltaic industry needs to make after implementation.
The operation and maintenance system needs to be improved
Home photovoltaics is a system engineering, and everything doesn't go smoothly after installation. The operation and maintenance of household photovoltaics require technical and professional knowledge, but in rural areas, there is a lack of such technical support, and some short-term training programs have poor results. Many homeowners do not attach importance to operation and maintenance, or are still unclear about how to operate and maintain them. Some have not been cleaned since installing their home photovoltaic power plants, resulting in a lot of surface stains on the components.
Yingli launched the overall system brand of Yineng to emphasize quality and service. "Ren Xiaokun introduced Yineng's operation and maintenance system to the reporter of" Energy ". Basic maintenance such as photovoltaic panel cleaning is completed by the homeowner themselves. Yineng adopts a combination of online and offline methods, with real-time tracking of dynamics through an after-sales monitoring platform online and regular maintenance by professional personnel offline. It has its own service standard to ensure 24-hour response and 48 hour solution. Whether the entire industry can have its own comprehensive operation and maintenance system requires more practice in the future.
In addition, Energy reporters learned during on-site inspections that some rural areas have the problem of small transformer capacity. If the difficulty of developing household photovoltaics in 2016 was that the general public did not understand the policies and did not want to install photovoltaics, then the problem in 2017 was that residents wanted to install photovoltaics but could not.
How to throw the subsidy crutch?
The rapid development of home photovoltaics in 2017 is largely attributed to policy subsidies, but relying on subsidy advantages is not a long-term solution, and the future development of home photovoltaics will gradually move away from subsidies.
Kou Fenghai, Chief Engineer of Hebei Electric Power Survey and Design Institute of China Power Construction Corporation, expressed a very optimistic attitude towards the future development situation from an economic perspective at the "Rooftop Photovoltaic Power Generation (Hebei) Lecture Hall": "Farmers spend tens of thousands of yuan to build a photovoltaic power station. With various access conditions and support policies, achieving a return of 10% or more throughout the entire life cycle is very good for increasing farmers' income. Developing distributed photovoltaic village level power stations is a good form
Industry insiders optimistically believe that photovoltaics are an important aspect of energy transformation, and the shift from ground-based photovoltaics to rooftop photovoltaics is a major direction. The development of home photovoltaics is a trend with enormous potential. Similarly, the photovoltaic market is huge, and the demand for TAIC crosslinking agents is naturally increasing. Shanghai Dunmei specializes in producing crosslinking agent TAIC and is committed to becoming a professional supplier of solar film additives. Currently, Dunmei maintains long-term cooperation with many domestic solar film factories and has a good reputation.
