On 9th February, in the two industrial parks of Suzhou, a RENAC self-invested 1MW commercial roof-top PV plant was successfully connected to the grid. So far, a PV-Storage-Charging Smart Energy Park (Phase I) PV grid-connected project has been successfully completed, marking a new beginning for the transformation and upgrading of traditional industrial parks into green, low-carbon, smart digital parks.
This project was invested by RENAC POWER. The project integrates the multi-energy source including “industrial and commercial outdoor all-in-one ESS + three-phase grid-connected inverter + AC EV Charger + smart energy management platform developed by RENAC POWER”. The 1000KW rooftop PV system is composed of 18 units of R3-50K string inverters independently developed and produced by RENAC. The main working mode of this plant is for SELF-USE, while the surplus electricity generated will connect to the grid. In addition, several 7kW AC charging piles and a number of charging parking spaces for cars are installed in the park, and the “surplus power” part is given priority to supply new energy electric vehicles through RENAC’s RENA200 series industrial and commercial outdoor energy storage all-in-one machine and smart energy management platform (EMS energy management system) Charging, there is still “surplus power” stored in the lithium battery pack of the energy storage all-in-one machine, which meets the charging and high-efficiency energy storage needs of various new energy vehicles.
The estimated annual power generation of the project is about 1.168 million kWh, and the average annual utilization hours are 1,460 hours. It can save about 356.24 tons of standard coal, reduce about 1,019.66 tons of carbon dioxide emissions, about 2.88 tons of nitrogen oxides, and about 3.31 tons of sulfur dioxide. Good economic benefits, social benefits, environmental benefits and development benefits.
In view of the complex roof conditions of the park, and the fact that there are many fire water tanks, air-conditioning units and supporting pipelines, RENAC uses the self-developed smart energy management platform to carry out flexible and efficient design through drone site survey and 3D modeling. It can not only effectively eliminate the influence of occlusion sources, but also highly matches the load-bearing performance of different areas of the roof, realizing the perfect integration of safety, reliability and efficient power generation. This project can not only help the industrial park optimize the energy structure and further save operating costs, but also is another achievement of RENAC to promote the green transformation and upgrading of the industry and build a high-level green technology innovation ecology.
