APVIA-LONGi Solar Intersolar Europe Side Event in Munich/Germany was a success!

Time: 7/11/2018 2:15:10 PM                       Publisher: Staff

Next Generation Solutions for Solar, Renewables and Energy Storage

This event was held at the Icm , Munich, where APVIA presented a one-day event on 21 June 2018 starting at 9:00am and finishing at 17:30pm.

For attendees, APVIA also provide a free three-day exhibition ticket!

The programme started with short welcome addresses by Prof. Eicke R. WeberProf. emerit., Dept. of Materials Science, UC Berkeley, Vice-President, International Solar Energy Society ISES; Burkhard Holder,managing direcor, VDE renewables; Gerald Müller, VP Sales Europe LONGI Solar.

This was followed by a Keynote Presentation on the subject of High efficiency and power output - new generation module” introduced by Dr.Fang Hongbin, Director of Product Marketing, LONGi Solar, who also made a presentation during the session three.

Dr. Fang

At session 1 on ‘Storage: Empowering the Sustainable Energy Infrastructure of the Future’, Julian Jansen, Senior Market Analyst, from IHS Markit made a presentation on ‘What’s in store for energy storage? Progress update on the global ESS market’, saying that Markets tend to evolve from single applications – to a wider range of stackable values. And panel discussion mainly discussing ‘Evaluating energy storage technologies, applications and business models’was followed then.

At session 3, TaiyangNews moderated during the Next Generation Solution of Solar Renewables and Energy Storage a panel on Mono PERC & Bifacial The Next Big Thing in Solar.

In his keynote presentation, TaiyangNews managing director Michael Schmela tried to answer Why Mono Bifacial Module Technology is the Next Big Thing in Solar? His answer was pretty clear, when he pointed to the newly released TaiyangNews Bifacial Solar Technology Report 2018. Advanced high-efficiency solar cell technologies are basically all naturally bifacial, which allows power generation on both sides of the solar cell at almost no extra cost, he said, adding A 5 to 30% gain in output promises a step change in LCOE reduction, which will result in a much faster adoption of bifacial technology than most people think.

While Schmela discussed the pros & cons for the different cell technologies, he concluded, With PERC having already conquered the mono space, going bifacial is not a big deal on cell and module level and it is happening.

 LONGi Solars director of product marketing Hongbin Fang, explained why he believes that Mono PERC is the Better LCOE Solution. First of all, Fang emphasized that a mono wafer simply offers the better quality material than multi, which results in higher cell efficiencies. Combined with drastically reduced mono wafer manufacturing costs in the last few years there is only upside using mono PERC, he added. Higher power densities lead to balance-of-system and total system cost savings, the technology shows better energy yields and slower power degradation, which results in what everyone is looking for lower LCOEs.

 

LONGis April 2017 Hi-MO2 bifacial mono PERC module series with over 300W for a 60-cell panel has shown in a field test a 14.3% higher yield compared to standard multi modules with both crystalline varieties being mounted on trackers. This year, LONGi has introduced its new Hi-MO3 bifacial mono PERC module, which is based on half-cut cells that due to reduced resistivity losses increase module power ratings by 5-10 W. The new 60-cell equivalent panel (120 half cells) has a power rating of 320 W and a bifaciality of over 75%.

Half cells are one way to improve module power ratings, but there are many more methods to tweak the cell-to-module efficiency, as presented by Harry Wirth, division head PV modules and power plants at Fraunhofer ISE. With the module cost share in total system cost having dramatically declined, a strong lever has been created to improve efficiencies on the cell and module level as well as performance ratio. And thats why today the proper focus must be system yield and not module STC power anymore, Wirth emphasized, which in return means a move to bifacial technology.

There are, however, some teething troubles that need to be overcome before bifacial can fully tap its potential. A missing common testing standard is one of these issues. Markus Schweiger, team leader performance and analytics at TÜV Rheinland noted in his presentation that the stated power rating of bifacial PV modules on the market is often inconsistent, while bifacial coefficients of PV manufacturers vary significantly. Moreover, the advantage in energy yield performance depends strongly on site-specific conditions. Schweiger asked for stabilization procedures, reliability and qualification testing to be adopted. While an IEC testing standard is anticipated to be published in 2019, TÜV Rheinland has its bifacial standard test conditions up and running and will even issue a first energy yield rating label this summer.
