Promote a revolution in energy production and consumption, and build a clean, low-carbon, safe, and efficient energy system
At present, China is in the early stages of the energy transition, aiming to establish a clean, low-carbon, safe, and efficient energy system, as well as a sustainable energy system to ensure energy security. The new energy industry possesses advantages such as low resource consumption, high cleanliness, vast market potential, strong driving capacity, and comprehensive benefits. The development and utilization of new energy play a significant role in adjusting the energy structure, promoting the revolution in energy production and consumption, and advancing the construction of ecological civilization.

Beijing Kongsang Technology Park B Zone Standard Factory Roof Distributed PV Project Overview
The Beijing Kongsang Technology Park B Zone Standard Factory Roof Distributed PV Project utilizes the available roof space of 11 buildings within the park to install photovoltaic (PV) systems. The project employs polycrystalline PV modules with a capacity of 320 W per unit, model 1960 × 992 mm, achieving a total installed capacity of 1,186.56 kW.
The rooftop modules are all installed using fixed mounting brackets, with a tilt angle of 10°/20°. Inverters and combiner boxes are placed on the respective rooftops. The direct current (DC) generated by the modules is converted to alternating current (AC) by the inverters and then connected to the low-voltage power grid system on the user side of the first-floor electrical room of each building. The project uses a 0.4 kV grid connection.
Providing comprehensive solutions through extension based on advanced technology
Langsung Electric, as the EPC general contracting unit of the project, successfully completed the project construction and grid connection while actively ensuring the operation and maintenance of the photovoltaic power generation. The project's power generation in 2019 was 1,632,517 kW·h.
