Silevo advised that it had exited its stealth mode with its new proprietary Triex technology. The hybrid solar solution is said to combine high-performance crystalline silicon N-type substrates, thin-film passivation layers and a tunneling oxide layer in one solar module. The solar module is powered by the company’s tunneling junction, which it states allows for the three materials to cohesively work together and produce high-efficiency, competitive module costs with optimum energy yield.

Silevo’s corporate headquarters in California’s Silicon Valley are supported by its R&D and manufacturing operation base in Asia. The company recently finalized US$33 million in financing with New Margin, a new lead investor, which was joined by GSR & DT Capital. The company intends to use the financing to develop a high-volume manufacturing facility in Hangzhou, China and explore advanced research to bring Triex to 24% conversion efficiency.

“Since our collaboration started in 2009, Silevo has matured their cell technology from R&D cells of ~13% efficiency to pilot production cells of ~21% efficiency-an impressive 60% improvement. They have achieved these gains by rethinking conventional silicon cells and taking innovative approaches to optimize all aspects of device performance rather than focusing on incremental improvements to efficiency,” said Dr. Bruce King, PV performance team lead at Sandia National Laboratories.

The company has modules in pilot production with the Triex cells said to be showing between a 20% and 21% conversion efficiency on full-size substrates with proven production materials. Customer qualification samples were shipped today from its pilot production center in Fremont, California with high-volume commercial production slated to begin in the first half of 2012.

As New South Wales is gearing up to become a renewable energy superpower, an exciting clean energy event is coming to Sydney. Energy Next is a free-to-attend industry event focusing on the latest renewable energy and energy management technologies, which will be held from 19-20 July 2022 at the ICC Sydney in Darling Harbour. Organised by the same people behind the country’s largest clean energy event, All-Energy Australia, Energy Next will bring a quality exhibition and technical session series to NSW. Energy Next will also host the Clean Energy Council’s Solar Masterclass with a program developed for solar designers and installers. Across two days, Energy Next will provide an extensive exhibition, workshops and networking opportunities for those working in the renewable energy industry to meet with leading suppliers, discover the latest technologies and gain an understanding of how to successfully launch new clean energy projects.

Join us for this free webinar on 20th July as Finlay Colville, Head of Research at Solar Media, provides a detailed update on the UK's solar industry today: Where is growth coming from, how much deployment is likely over the next 12-18 months? The large-scale solar farm pipeline at 40 GW and still going up – how much is getting built today? Commercial rooftops - the big story of UK solar in 2022; but is this just the tip of the iceberg? Why are PV module prices going up? What will happen in the next couple of years? The era of PV modules at 500 Watts and above: what is driving this?

The rooftop solar PV market is set for significant growth, but installers are being held back by complicated design software that is slow, cumbersome and fails to take into account rooftop shading, module compatibility and energy storage. Huawei’s SmartDesign 2.0 is a web-based PV and energy storage system tool that promises to solve all of those issues, and much more. This webinar will provide a live demonstration of the SmartDeisgn 2.0 tool, showing how installers can quickly complete Huawei PV & ESS system designs and assemble a professional report with 3D site view for potential customers, streamlining the design and sales service.

The corporate renewable market is growing rapidly driven by increasing focus on decarbonisation and sustainability. There are several procurement options already popular today – open access, rooftop solar, RECs and green tariffs. Some new procurement routes as well as technologies are emerging – VPPA, storage, round-the-clock PPAs etc. Each procurement option comes with unique benefits and challenges related to policy and regulatory framework, commercial feasibility, contractual terms, execution and operational aspects. This programme is designed to empower business managers with adequate knowledge and skills to analyse different procurement options and develop an optimal roadmap based on their individual needs. The programme will be conducted by BRIDGE TO INDIA team supported by leading experts from the renewable energy industry.

As solar PV projects embrace large-format and bifacial PV modules, inverters are evolving to deliver benefits across all three main LCOE variables, namely Capex, Opex and yield. However, asset operators are also demanding more oversight of the health of their projects, in turn demanding even more from modern inverter technology. This webinar will discuss how modern solar inverters have evolved to keep pace with PV module technology, providing real-life examples of how GoodWe has solved challenges for solar project developers and asset managers.
