Distributed solar PV systems have long been an important part of the clean energy mix. Most solar projects are 1100V and 1000V, but with the adjustment of guidelines around the world, grid parity, cost reduction and increased efficiency have become the main considerations of the distributed power plant developers. Under this new green power ecology, the 1500V system is gradually becoming mainstream in large-scale projects like ground power plants. With its high-voltage array, low line loss, high efficiency, high power density, and easy installation and maintenance, a 1500 V system is a logical choice.
Can C&I rooftop projects, which have an important position in distributed power plants, also use 1500 V systems? In this seminar we will introduce you to the application challenges of the 1500V system in C&I projects with an actual green power project at a competitive price.
In order to actively react to the national strategy for energy saving and emission reduction and to lower the company’s electricity costs, Hai Dexin Automotive Appliances in China decided for Solis for a PV solar system on the production site and on the roofs of the office building.
The preliminary study of the site by the designers found that the total capacity can reach 1.5 MW. According to the comprehensive analysis of the project capacity and current electricity supply and consumption of the company, the Power Supply Bureau recommended the solar installation to use a 10 kV high voltage network and classify it as a self-generated and self-generated surplus electricity project and prepare a project grid connection report.
Plan & design comparison
The project is connected to a high voltage network, the roof environment is good, the space is large, and it is easy to align. The project capacity is expected to reach 1.5 MW. In summary, all conditions are suitable for Solis high-performance inverter solutions. The Solis design team has therefore provided two sets of solutions for the successful implementation of the project.
