Chinese module manufacturer Astronergy has designed a solar PV, battery storage and building integrated photovoltaics (BIPV) micro-grid system for the Haining Zhengtai Industrial Park.

Located between the eastern Chinese cities of Hangzhou and Jiaxing, the park is home to high-end equipment manufacturing and advanced information technology companies.

Astronergy said industrial parks’ demand for energy security is “booming” amid a climate of rising costs and needs.

Its solution has been to create a 5.9MW distributed solar power system built within the factory alongside a DC coupling micro-grid system. The micro-grid integrates an 8.83kW BIPV PV hut, a 50kW BIPV PV parking shed, a 4.5kW PV road and ribbon-shaped PV corridor, a 35kW PV lab and a 5kW vertical axis wind turbine.

Astronergy said developing low-carbon and zero-carbon buildings is important for energy conservation, emission reduction and environmental protection. “Every year, there are about 4 billion square meters of housing area being constructed, among which 5% uses BIPV,” the company claimed, adding the BIPV market will soon be worth RMB100 billion (US$14.6 billion).

The energy generation technologies are connected to the micro-grid through intelligent power electronic conversion equipment, Astronergy said. There is also a 50kW/100kWh energy storage system to support generation fluctuation smoothing, system load shifting and uninterrupted voltage support for sustained power supply to the companies within the park.

Established in 2006, Astronergy has manufacturing bases in the Chinese provinces of Zhejiang, Jiangsu and Gansu as well as Thailand. By the end of 2022, Astronergy said its solar cell production capacity will reach 13GW, while its module production capacity will reach 18GW.

In April, Astronergy announced its plans to launch its first TOPCon n-type modules under its ASTRO series that contains three new n-type products covering M10 and G12 cells, catering for different markets from residential to utility-scale and commercial & industrial (C&I).

FREE WEBINAR -This special webinar will take a deep dive into the latest PV ModuleTech Bankability Ratings pyramid, capturing the relative bankability status of the top 70-80 PV module suppliers globally. In addition to revealing the latest ranking of global PV module suppliers, PV Tech’s Head of Research, Finlay Colville, will show the depth of analysis and commentary included within the report for module suppliers. A key output from the webinar will be to learn which PV module suppliers have moved up the rankings pyramid in recent years and why this growth has been achieved. Conversely, some of the companies that have fallen down the rankings will be discussed, in particular those suffering from market-share losses and financial problems.
