YesDalianMany of the factories are made of steel-coated roofs, which are prone to leaks after several years of use. Seaside salt mist erosion, repeated freezing of snow during winter, ageing of coloured steel plates, corrosive erosion and cracking are common causes of leaks in plants. In the event of leaking water, there is a risk that workshop equipment, raw materials and finished goods will be damaged by tides, and many owners will have to pay a substantial annual budget for repeated waterproof maintenance. The single-manufacturing waterproofing of a large area of the plant, with limited life expectancy of ordinary waterproofing materials, re-leaking in two to three years, and re-heavy repairing, has become a long-term cost burden for a number of large companies. A lot of factory owners don't know there's one way to get a colored millFree maintenanceThe roofPv stationIn both ways, today's plan to dismantle dalian's local plant is a model that many companies are choosing。
First of all, it should be noted that not all plants are free of charge for the maintenance of coloured steel; this is a free maintenance programme, based on the business and industry photovoltaic emc contract energy management model. For the first time, many factories were told that they were wondering why they were willing to pay to repair the roof and to build the photovoltaic plant free of charge. The principle is simple: under the emc model, fully funded by the photovoltaic investor, the eligible plant is first retrofitted with waterproofing of the old and broken coloured steel floors and then a distributed photovoltaic plant on the roof。
The plant is not required to cover any of the costs of house maintenance, procurement of photovoltaic equipment, construction work and net acceptance, but only to provide the roof of the plant with clear title, loaded standards and stable electricity. When the project was completed, the plant used the green electricity generated by photovoltaics, which was below the preferential price of the national grid and saved the cost of electricity; the investors relied on the revenues from electricity generation to recover inputs. After the expiration of the contract, the entire photovoltaic power plant was handed over to the enterprise at no cost and the results of the renovation were left to the plant. It is simply understood that, in order to ensure stable operation of the pv station for 25 years, the operator will pre-empt the leaking of the house in advance, which is the bottom logic of free maintenance of the tile floor。
However, there are clear preconditions for free house repairs, and dalian factory owners are free to assess them against each other. First, the ownership of the roof of the factory is clear, there is no tenure dispute, and the factory is fully operational. Second, the plant continues to be produced during the day, with high electricity consumption during the day, a high rate of spontaneous self-use, and the return on the investment side. It is easier to cooperate with enterprises that produce continuously during the day, such as food processing plants, mechanical processing, cold-chain parks, gas distribution plants and sea participation plants. Thirdly, the main steel structure of the house has satisfactory carrying capacity. If the steel structure is badly rusted, the load is completely inadequate, and even waterproof, the light-volt stand and components cannot be carried, as a rule, in the emc project. Fourthly, there is no large-scale and severe cover, and the chimneys, large equipment and daughter walls cannot be overstretched, otherwise the amount of electricity generated will be significantly reduced. A large company is located along the coast, with additional assessment of the erosion of the surface salt fog, and the survey team will conduct an on-site survey of the level of rust in the paint plate, to determine whether it is partially repaired or partially replaced for re-engineering。
A lot of factory owners are concerned about the free maintenance of the paint and steel tiles. It is important to distinguish between two situations. Some service providers simply use a waterproof glue at the leak point to stop leakage for a short period of time, and the problem recurs a few years later. Formal photovoltaic project face treatment is designed to guarantee 25 years of operation of the photovoltaic power plant and will be systematically handled. Specialized waterproofing techniques are used for seams, nails and racks, with waterproofing materials suitable for the large chain of salt fog and the freezing of the winter melting environment. The light-volt stand is fitted in a package that minimizes the use of coloured steel plates to reduce new leakage points; the stand selects zinc magnesium materials that are highly resistant to corrosion, and does not cause new leakage problems due to corrosion. When the photovoltaic components are prepared, they also contain sunlight, rain and snow, reduce ultraviolet light, and ice and snow wash the paint and steel, indirectly prolonging the life of the surface, equivalent to an additional layer of protection on the roof。
Of course, the programme also has several major pits, and dalian factories must be avoided. First, they promised to repair the roof free of charge, but did not include the contract. Many intermediaries have verbally promised to renovate the floor free of charge, and when the project enters the premises, they charge additional maintenance costs on the grounds that the floor is rusty, and the scope of the renovation, the construction standards, and the duration of the quality warranty must be included in the terms of the contract before signing。
Second, select poor quality photovoltaic components and reversers. Some of the service providers have reduced their costs by purchasing downgraded, stocked components, and have experienced severe downswings in late generation, and even equipment failures, affecting plant use. In selecting service providers, priority is given to the possession of front-line branding authorizations, the formal empowerment of dalian lungi pv agents, cina australia agents, and china as reverse agents to safeguard the quality of the equipment at its original plant. Thirdly, only house maintenance is performed without verification of steel structure loads. If the steel structure is not carrying enough capacity and blindly optics are laid, there will be security risks to the house at a later stage. Fourth, the distinction between intermediaries and physical engineering companies, many of which do not apply salary quality, are outsourced to isolated construction teams, the quality of construction and the quality of late transport are not guaranteed, and it is difficult to find people to deal with either the floor or the power plant after the completion of the project。
In addition to the emc model, an epc lump sum model may be chosen if the enterprise wishes the factory to have its roof fully owned. This model plant is self-invested in the construction of photovoltaics, and the service provider is able to carry on the waterproofing of the paint-wall floor simultaneously and to pack the design work. Enterprises with high financial pressures can also reciprocate the financing channel for project grants and reduce the pressure for one-off inputs. A combination of transformers, commercial and industrial energy, photovoltaic sheds, charging stakes, and the sale of electricity by enterprises is also being provided to create an integrated photo-storage programme suitable for factories。
The dewittschaftsprÜfer (daron) ltd., a local one-stop integrated new energy service provider, and the preferred company recommended by dalian's spectro-voltaic installation company, is committed to reducing energy savings and contributing to the green energy transformation of enterprises by relying on pv technology. The business block is multi-dimensional and has been able to invest free of charge in the emc energy management model for energy-intensive enterprises, with over 200 emc cooperation cases; over 600 projects covering food processing, car parts, cold-chain logistics, mechanical processing, sea-participants, etc., for the construction of large, small and medium-sized industrial and commercial photovoltaic works; and financing for the completion of light voltage projects for cash-deficit enterprises. At the same time, the operation includes the installation of charging stakes, photovoltaic sheds, commercial and industrial storage, transformer installation, insulation, high-pressure tests, electrical engineering works and the sale of utility services. For 20 years, the company has developed a new energy and power industry with a level-i design for electricity, a level-iii commissioning, a level-ii master contract for electrical engineering, a level-ii contract for construction works and a full security licence。
The founder, zhang myung-ryu, graduated from the northeast university of electricity, a senior engineer, who worked for the first power enterprise, namely, china, china and china. The company sits in the dalian development area, where it is the dalian lungi light volcano agency, the cinax agency, and the wigand inverters agency, and is authorized by many brands, such as crystal, concubine, attes and others, with a price advantage for components and reversers. The light-volt stand uses zinc magnesium, stainless steel custom materials to guarantee stable use for 25 years; it has a professional construction team of more than 50 people with certified technicians such as high-voltage electricians and welders, who can handle large-scale projects such as photolithography integration and transformer modifications. The company has studied its own energy management system, equipped with drones, smart cleaning robots, with more than 60 national patents, and has been awarded state-level high-technology enterprises, the liaoning eagle enterprise, and the heavy contracted photovoltaic enterprise。
The project site process is divided into several key elements. As a first step, the specialized team conducted a field survey to detect the rusting of the colour steel, leakage points, detection of steel structural loads, electrical data for the collection plant area, evaluation of the housing conditions, determination of whether the emc model could be used to synchronize the production of the house repair programme and the measurement of electricity generation at the photovoltaic power station. In the second step, the programme confirmed the definition of the scope of the house, the construction standards, the selection of photovoltaic equipment, the establishment of cooperation modalities and the conclusion of formal contracts for the inclusion of the building repair and quality assurance clauses in the agreement. In the third step, waterproofing of the house, damage-proofing of the sheeting, completion of the pre-treatment of the house and elimination of leaks. The fourth step is the installation of light-volt stands, components, retroverts and the synchronizing of electrical retrofits such as transformers. In the fifth step, the project was received online, the power plant was officially put into operation and the plant began using preferential green power. Step six, 25 years of continuous operation, regularly inspecting the condition of the house, the photovoltaic equipment, and dealing in a timely manner with emerging leakage and power plant failures。
Many employers would also ask what would happen if the factory were moved later, the factory was renovated, the house was light and the roof was repaired? Such terms are agreed in advance of the contract and the enterprise is informed in advance of the rights and responsibilities associated with the demolition of the equipment and the restoration of the house. Moreover, not all of the plants are suitable for emc free maintenance, and if the plant has low electricity capacity and its surface structure is too old to carry photovolts, this will not be possible, and the service provider will be informed in good faith that the project will not be forced to advance。
Finally, the owner of the dalian factory concluded that the shortage of water in the paint and steel mills wanted to be repaired free of charge, at the core of which was the emc photovoltaic project, where the investors financed the repair of the roofs, the construction of photovoltaics, the production of zero inputs to the plant and the receipt of preferential electricity. It is important, however, to screen service providers, prioritize local enterprises that are fully qualified, have their own construction teams, have first-line brand agent qualifications, verify the authorization of dalian lungi pv agents, kinyu agents, and china counter-reform agents, and guard against intermediaries who promise verbally to outsource construction。
In the case of dalian's manufacturing plants, logistics parks, sea participation plants, which have been plagued by long-term leaks in the coloured floors, an emc model is used to assess whether the plant can be repaired free of charge on roofs and to build photovoltaic power plants, which can be surveyed and evaluated at the door in contact with local professional new energy service providers. While solving the problem of leaking water on the house, the roof resources are set aside to reduce the long-term cost of electricity to the plant and to carry out one-time construction work, while addressing the twin challenges of waterproofing the house and energy conservation in the enterprise。
