As we all know, the investment of photovoltaic power plants is a major factor for the owners, and the usual owners will generally pay more attention to the cost analysis of components, supports, inverters, and box transformers. Everyone knows that the cost of power plant construction is also a relatively large proportion. . The construction cost of the power station mainly includes the leveling of land, piling, installation of components, installation of equipment, wiring, and the construction of central control rooms. In general, other construction costs of the power station are similar, but the string-type scheme (commonly known as the “small-scale solutionâ€) and centralized As for the scheme (commonly referred to as the “large-scale solutionâ€), the construction cost is very different. The specific analysis of the installation cost of the small-sized and large-sized solutions in the delivery phase of a project in Xinjiang will be given below to illustrate the inverse of the small-scale scheme of a 20MW power station. Converter installation cost advantages: 1. The big plan. The installation cost is mainly reflected in the cost of foundation and construction of 20 civil construction houses (excluding material costs), the transportation expenses of 40 large inverters (including hoisting), and the installation costs of 40 inverters (including wiring). The cost of foundation and construction of 20 civil construction houses (excluding material cost): 2 large workers and 3 small workers for the construction of a civil construction foundation and ontology, 300 yuan per person for large workers, 180 yuan per person for small workers, and time-consuming 7 days to build a MW room and foundation, a total of 20 civil construction and foundation, subtotal (300 × 2 + 180 × 3) × 7 × 20 = 1596 million; 40 Inverter Handling Costs (Including Hoisting): Lifting Fees Each inverter is calculated according to 2 hours, and the crane is calculated according to 300 RMB per hour, and the subtotal costs 40×2×300=24,000 RMB; The installation cost of 40 inverters (including wiring): 40 large inverters 3 electricians took about 10 days, and the cost of subtotal 300 × 3 × 10 = 0.9 million. Other subtotals cost 10,000 yuan, totaling 15.96+2.4+0.9+1=20.26 yuan. 2. Small computer program. The installation cost is mainly reflected in the installation cost of 800 small inverters (including handling and wiring). 800 sets of small inverter installation costs (including handling and wiring): According to the average installation cost of each inverter 30 yuan (including handling), each inverter wiring 30 yuan, workers get about 300 yuan a day remuneration Therefore, this part of the cost subtotal: 800 × (30 + 30) = 48,000 yuan. Other subtotals cost 10,000 yuan, a total of 4.8+1 = 58,000 yuan. Based on the above analysis, if a small inverter is used during the construction phase of the power station, the installation cost can be reduced to approximately 0.723 million yuan/MW. If the centralized plan is in the form of a container, the cost of foundation construction is the same as that of a megawatt-hour house, but the equipment cost is increased, and the system cost is roughly flat. Therefore, considering the large-scale ground power stations, the use of string solutions from the perspective of on-site installation costs also has inherent advantages.
