Manufacturing

As part of a focus on PV module and system quality in preparation for our Quality Roundtable at the Solar Power International Trade show in Las Vegas, pv magazine brings you an interview with DuPont Research Fellow Bill Gambogi and Director of Corporate Marketing Bob Olsen.

Quality control campaign: PV panel manufacturers selling plug connectors as MC4 compatible is nothing unusual. Two operators who have installed such modules are now struggling with lost insurance coverage and fires.

Changing technology, pressure to cut costs, dizzying price slumps and a number of other issues make solar module quality control as relevant as ever. The danger that modules could fail outright remains slim, so module reliability is still decisive for the success of the investment, explains George Touloupas, Director of Technology and Quality at CEA, in preparation of the 4th pv magazine Quality roundtable at SPI.

Quality roundtable preparation: A case of compromised quality. An operator claims nearly 17% of the modules in his array displayed significant damage after three years. The EPC company concealed the damage from the investor until the warranty had expired. The module manufacturer responded slowly and only out of goodwill.

An installation company in the Midwest reports how blame was laid at their door for defective PV panels. The actual cause of the defects probably lie elsewhere.

Failures in residential solar systems can be the bane of an installer, who is often paid merely to install the system, not necessarily to back the various component warranties.

SunLink has launched TechTrack Distributed, its distributed single-axis tracker, featuring dynamic design, site flexibility and total cost reduction.

U.S. tracker manufacturer NEXTracker has purchased software firm BrightBox Technologies in a move it says will augment its predictive modeling capabilities and expedite the commissioning process.

The Chinese polysilicon and PV maker will buy three of SunEdison’s manufacturing businesses involved in polysilicon production up until cell production, amid rumors that it is also planning to make a bid for SunEdison’s controlling stake in TerraForm Power.

A revision request has now been received by the appropriate court in Michigan. SolarWorld has meanwhile filled further protective letters against Hemlock to various courts in Germany, as a precaution to prevent possible enforcement of any penalty in Germany. SolarWorld CEO Frank Asbeck is confident that the U.S. silicon manufacturer will not receive recognition of any judgements in German courts.
