Modules & Upstream Manufacturing

Product piracy is a well-known threat in many industries, and in solar the risk posed by poor quality products from disreputable manufacturers making their way onto rooftops and other PV installations should not be underestimated. With manufacturers investing in solutions to protect against inferior products bearing their logo, pv magazine looks at the size of the problem.

Seven PV module manufacturers – including JinkoSolar, Longi and JA Solar – won supply contracts this week in a 3 GW procurement round held by China National Nuclear Corp. Flat Glass revealed plans to raise $282.6 million to expand production, while the National Energy Administration reported growth in the residential PV segment.

Through a CHF165 million capital increase, the Swiss company intends to finance the expansion of capacities for highly efficient solar cells and solar modules in Germany. Production is scheduled to start next year. The strategic partnership with REC Group has been discontinued.

National Taiwan University and Taiwanese PV production equipment provider E-Sun Precision Industrial Co. have developed equipment to produce different kinds of perovskite cells with varying chemical compositions. The first trials achieved 14.3% conversion efficiency rates.

As the solar industry starts to embrace ultra-high-efficiency modules, the Chinese PV heavyweight has unveiled TrinaPro Mega, the first integrated solar system in the world that incorporates 500 W+ modules.

The spherical 3D cells can reportedly generate around 101% more power than conventional flat solar cells. Measurements have also shown that the spherical cells provide a 10% lower maximum temperature compared to flat cells, while accumulating less dust.

Manufacturers shipped about 2.05 GW of PV modules in March, before plummeting to 1.24 GW in April. But while shipments slowed, the cost per watt peak reached a record low.

The Düsseldorf Regional Court has agreed rivals of the Korean manufacturer illegally used its patented passivation technology. The judges granted Hanwha Q-Cells an injunction which requires Jinko, REC and Longi to retrieve all modules featuring the patented technology distributed in Germany since late January last year. Hanwha can also opt to have the offending products destroyed.

A team of researchers led by Nanchang University in China trialed a polymer based hole transport layer to flexible perovskite solar cells, using a glue to attach it to the active perovskite. The team was able to assemble the 19.87%-efficient cells into a small flexible module suitable for wearable solar applications, and says its design was inspired by the structure and movements of human vertebrae.

Despite the challenges to both the manufacturing and shipment of its products during the period, JinkoSolar today reported that it shipped 3.4 GW of modules in the first quarter of 2020, bringing its revenue for the quarter just over the billion dollar mark.
