Boviet Solar wins 138 MW module order from US developer – pv magazine USA

The supplier of PERC PV cells, monofacial and bifacial solar modules will supply its Vega series modules for a US project.

Boviet Solar, a cell and module manufacturer based in Vietnam and operating in the United States, announced that it has secured an order for 138 MW solar modules with a major US project developer. The developer has chosen Boviet’s Vega Series 550 W PERC (passivated emitter and back cell) bifacial monocrystalline PV modules. The name of the developer has not yet been disclosed.

Vega Series panels feature high-purity monocrystalline wafer technology combined with PERC, half-cut, multi-busbar, and large-cell design modules. The 550W module includes 10 busbars, 144 cells, a silver frame and a transparent backsheet. It holds a module efficiency of 21.1% and a system voltage of 1000/1500 V DC. It has a maximum output power of 433W and is rated to operate between -40 degrees F and 185 degrees F.

Each module measures 90.40 x 44.65 x 1.38 inches and weighs just under 64 pounds. It has a 25-year linear output warranty with 2.5% degradation in the first year and less than 0.6% from the second year until the end of the warranty. It also comes with a standard 12-year product warranty.

Solar modules have been one of the top performing PVEL products on its dashboard since 2019 and BloombergNEF Tier 1 status since 2017. BloombergNEF’s tiering system for PV module manufacturers is primarily based on bankability, characteristic most important utility scale solar module for most developers.

In May, the company was listed as “Top Performer” in the PV Evolutions Labs (PVEL) 2022 PV Module Reliability Scorecard for the fourth consecutive time.

“We congratulate Boviet Solar for listing the modules in all Top Performer Scorecard categories,” said Tristan Erion-Lorico PVEL, Vice President of Sales and Marketing. “PVEL congratulates Boviet on the excellent results they have demonstrated throughout our rigorous testing.”

“Boviet Solar continues to be a reliable source of high quality photovoltaic modules for the US market. This ability to deliver modules despite the uncertainties affecting the US solar industry is essential for our customers and their projects, and it remains a priority for Boviet Solar,” said Sienna Cen, President of Boviet Solar USA.

Switch to new technologies

Last April, Boviet announced that it was developing new module technologies to meet the changing needs of project developers. He is working on a new N-tunnel oxide passivated contact cell (TOPCon) technology, which he says is more efficient and stable. He is also working on a second R&D project to integrate N-TOPCon cells into 600W+ modules. The modules will feature an advanced package and benefit from a low temperature coefficient, low attenuation and higher double-sided ratios, Boviet said.

Additionally, Boviet Solar said it is targeting heterojunction cell technology (HJT). He said he expects HJT to become the next-generation mainstream technology, with an efficiency rate of 27.5%.

Boviet is not the only company to switch to TOPCon. The world’s major solar manufacturers can be expected to switch from standard PERC products to TOPCon technology “in the next few years”, according to a US analyst.

The technological change caused by manufacturers approaching PERC’s conversion efficiency threshold of 23.7% – for commercially manufactured products – is one of the predictions made by Denver-based Clean Energy Associates (CEA) in its survey of the solar manufacturing industry in the last three months of 2021.
