The roof has completed a large sweep, and the distributed development is faced with kinetic energy conversion. Investing in the roof of a commercial power plant owner to build a distributed photovoltaic power station and obtaining a certain return on investment is one of the major modes of business and industrial roof development in 2017. However, the relationship between the method and the owner of the property is fragile, and it is necessary to ensure the existence of stable business for 20 years. Many uncertainties. Cooperation with industrial and commercial owners in the form of electricity tariff discounts is better than pure leasing. After all, they also maintain a common interest with the owners. Driven by a large number of companies with investment and rewards, a nationwide industrial and commercial household has completed a major sweep with a roof, which can be said to be a scientific knowledge of photovoltaic science; in the case of mutual recognition, it will be low by 2017. Clean energy companies that invest in leases or electricity discounts will face the bottleneck of development. It can be said that this development model will gradually lose its business development market in 2018. From the second half of 2016 to the 2017 Photovoltaic Science Popularization, the roof owner not only understands the basic economic characteristics of photovoltaic power generation but also invests in distributed photovoltaic power plants during the communication between the wheel and many photovoltaic investment institutions. The benefits have deepened the understanding that the “fat and water will not leave outside people's fields†and the supporting financial environment are maturing. Some large enterprises with high-quality roofs will increasingly establish their own clean energy to invest in their own roofs. Clean energy investment companies can not ignore this phenomenon and information, "do not forget the initial heart" to jointly promote the application of clean energy to the entire society is the key to supporting the sustainable development of enterprises. Transformation services The professional talents of the distributed investment companies that have already operated are one of the advantages of stocks. The new clean energy investment company needs professionals to control the characteristics of photovoltaic power plants and the construction management of the projects. This situation is the transformation of investment-oriented companies into system integration. Service companies have an opportunity, such as the company can not face changes in the market, will face business stoppages and brain drain. The use of distributed photovoltaics by industrial and commercial households is still the development climax in 2018 and 2019, but owner-occupiers will become the main trend. The transformation of large-scale rooftop PV investors will be jointly developed with large-area enterprise groups or the system integration service model will be transformed. The epc companies have more job opportunities, and the winning companies use the joint venture + system integration services + EPC. The most important test is the cross-border and enterprise group's cooperation and communication capabilities and sincerity of cooperation. In fact, over-emphasizing the economic value of photovoltaics and ignoring the contribution of photovoltaics to low-carbon development have not been successful in promoting distributed photovoltaics business. Most companies are not for that point of rental and limited electricity charges. (JHC International New Energy Power, author: Yin Qi deposit)
