Trina solar leading the compatibility charge in the ultra-high power era

Trina Solar continues to drive collaboration across the entire value chain to achieve full compatibility with Vertex 210mm silicon wafer modules, designed to enable 600W+ output. Since the launch of Vertex modules a year ago, the range of 210 Vertex compatible solar PV system components continues to expand. Numerous market tests have been completed with compatibility approvals from leading solar inverter and tracker manufacturers, enabling the upgrade in power.

In the race towards a climate-neutral economy in Europe, as set out in the EU Green Deal, Ultra High-Power solar energy systems play a vital role. The market is maturing fast, with Trina Solar at the forefront of production and open, collaborative innovation across the industry chain.

Trina Solar’s creation of three new 210 Vertex super factories in 2020 secures consistent product supply, projected to reach over 50GW globally at the end of 2021. This brings new-found confidence in high-energy solutions to the solar market, and more importantly, strengthens the value proposition of solar energy across utility sector.

The 600W+ Photovoltaic Open Innovation Ecological Alliance

One of Trina Solar’s first initiatives after launching 210mm technology helped to bring together influential solar companies and pledge a commitment to drive ultra-high power capabilities in the industry. The 600W+ Photovoltaic Open Innovation Ecological Alliance, announced in July 2020, is now made up of 66 companies spanning the industry in Europe and globally, across silicon, wafers, batteries, modules, inverters, tracker systems, materials, EPC, design institutes, professional research institutions and owners.

This Alliance aims to create a new collaborative and innovative ecosystem through open collaboration, synergizing the industry chain’s primary resources and integrating core processes such as R and D, manufacturing, and applications.

Member companies adopted a declaration stating they will work together to build products, systems, and standards for a next-generation technology platform, committing to maximizing the customer values of 600W+ Ultra-High Power modules and other related solutions at the application end.

Driving value in the Ultra-High Power Industry chain

Prior to March 2021, leading brands such as Huawei, Sungrow, SMA and Sineng announced the availability or launch timeline of 210 Vertex compatible central and string inverters.

We have also seen eight of the world’s leading photovoltaic tracker makers, Arctech Solar, Array Technologies, GameChange Solar, IDEEMATEC, Nextracker, PVH, Soltec, TrinaTracker, successively issue compatibility approvals for 210 Vertex modules.

These continuous compatibility advances with inverters, trackers and 210 modules raise the total system value and reduce costs in various scenarios. Specifically, low-voltage, high-current Vertex modules can realize a longer string, thereby reducing the number of strings, leading to reduction of BOS components, land and labor used, lowering overall EPC cost and LCOE, highlighting the power generation gain and cost advantages of ultra-high power modules.

An independent DNV GL assessment published in December 2020 calculated significant system advantages of Trina Solar’s bifacial dual-glass 210 Vertex modules. The report showed a reduction of BOS by 6.2% compared with conventional 166mm-450W and 182mm-535W modules in terms of BOS costs and LCOE by 3.72%.

This proactivity within the industry is paying off, demonstrating smooth chain collaboration and proven LCOE reductions, accelerating the entering grid parity era.

Researchers improve efficiency of next-generation solar cell material

Boston MA (SPX) Feb 25, 2021

Perovskites are a leading candidate for eventually replacing silicon as the material of choice for solar panels. They offer the potential for low-cost, low-temperature manufacturing of ultrathin, lightweight flexible cells, but so far their efficiency at converting sunlight to electricity has lagged behind that of silicon and some other alternatives.

Now, a new approach to the design of perovskite cells has pushed the material to match or exceed the efficiency of today’s typical silicon cell, whic … read more
