Intersolar Europe is always a key date in the solar calendar but this year’s show had it all, including three panel-smuggling arrests. Elsewhere, wafers were getting bigger, efficiency records were tumbling and new technologies were emerging. There was also more news on the solar car ports fad and Hanwha’s ongoing legal tussle.

The PV manufacturer announced the development of the new solar panels, which feature new M12 series monocrystalline wafers, at a conference on Thursday in the Chinese city of Ningbo. The 50-cell modules are actually slightly bigger than 72-cell designs with 156.75 mm wafers, it said.

Eleven U.S. Senators have signed a letter to the Federal Energy Regulatory Commission about the threat that Huawei’s equipment poses to the nation’s energy infrastructure.

The court has deferred a hearing of the second case, with Huawei claiming that was due to insufficient evidence of patent infringement. The European Patent Office has revoked SolarEdge’s inverter multi-level topology patent and the Israeli company said it intends to challenge both decisions.

Complaints about sub-standard, cheap PV imports from China – and notably, India – have been heeded by Dhaka, which has issued a requirement for modules, inverters, charge controllers and batteries to attain IEC electrical standards.

Italy’s main solar event, the Key Energy fair held in Rimini, demonstrated the continuing importance of rooftop PV for Italian renewables but also promised a gradual return for large scale solar. Industry insiders are hoping for at least one gigawatt of solar next year, on top of a projected 600 MW this year.

Inverter manufacturer Solaredge has filed three additional patent infringement lawsuits against its competitor, Huawei, in China. This comes after three similar legal actions against Huawei that had been undertaken by Solaredge in Germany last summer. While Huawei has decided not to comment on the matter, the Chinese manufacturer revealed that it had filed three patent litigation claims against Solaredge at a Chinese court this May.

The Emirati utility and the Chinese communications giant and inverter maker have discussed how they can work together to roll out solar and storage in Dubai as well as collaborating on cyber security and the use of AI to analyze cyber threats.

Roth Capital Partners has reported the inverter maker ceased U.S. sales on Friday, laying off all its U.S. citizen staff amid rising tensions between the Trump administration and China.

The Chinese string inverter giant was the world’s biggest supplier for the fourth year in a row, in spite of having lost 4% in global market shares, according to analyst Wood Mackenzie. Asia-Pacific was again the largest inverter market last year, accounting for 64% of global shipments. Sungrow and SMA were, respectively, the second and third largest providers.
