On Friday 6 November the Indian solar industry witnessed GoodWe’s nationwide launch of the much anticipated HT Series. The Suzhou-based multinational is widely recognized as a global leader in Commercial & Industrial projects but has recently been adding to its Utility portfolio with larger and more powerful solutions. The event, held at the Pullman resort in New Delhi, was attended by prominent figures of the Indian solar industry and offered an insight into what other projects GoodWe might set its sight on.
During the panel discussion, Mr. YBK Reddy, DGM – Solar (SECI) highlighted that demand for power is projected to reach 300GW in India and that the government has plans for hybrid tenders involving solar and other sources of renewable energy in its energy matrix. It is expected that more efficient component products and more reliable system solutions will be required to meet the demand.
GoodWe seems to have anticipated many of these demands and the success of its launch of the 1500V String Inverter was seen by many as the moment of truth. The new HT series is said to provide the lowest levelized cost of electricity (LCOE) and the industry’s most advanced safety features.
The debate at the Pullman resort touched on various trending topics including the long-standing Central vs String inverter comparison and the challenges and opportunities presented by the “600+ wafer era”.
String Inverters VS Central Inverters
Mr. Gaurav Wadhwa stressed that string inverters are the better choice and present advantages related to BoS costs. Adding to the point, Mr. Sudhir Pathak mentioned how less space is now being used with increased block sizes in the latest PV project designs. Pathak also added that this the logical pathway for string inverters to follow; to be more compact and more intelligent than ever for utility projects.
The Era of High-Power PV Modules
In terms of technological trends, the “Big” Era is now here with PV modules’ power moving from 500W to 600W+. At the HT product launch in New Delhi, Mr. Syed Naqvi agreed that increasing wafer sizes and number of wafers in PV modules represents a challenge for inverter manufacturers and increasing the current rating of PV module also requires inverter technology to go up one gear. In this aspect GoodWe also seems to have anticipated this trend, as reflected in its new product offering. The 1500V 250kW is said to be highly compatible with the latest high-power PV modules and bi-facial modules, allowing DC input currents of 15A.
GoodWe received congratulatory wishes from industry leaders and GoodWe’s vision for 2021 already presents sizeable investment opportunities and will likely play a key role in the country’s additional installed capacity targets for the 2021-2025 period.
