Refining the process

CdTe modules: At its production facility in Germany’s ‘Solar Valley,’ Calyxo is producing CdTe modules at production costs moving towards $0.20/W, many of which are destined for repowering PV plants across Europe. pv magazine caught up with Calyxo CTO and COO Michael Bauer, to discuss the company’s latest developments.

Troubleshooting efforts in PV plants

Plant maintenance: Troubleshooting in solar plants requires not only trying to find a diagnosis of why the performance ratio is reduced, but also to localize faulty modules. John Davies, Operations Director – Solar and Energy Storage at operations and maintenance firm Cobalt Energy, shares with pv magazine his thoughts on fault detection, troubleshooting, and thermography in the field.

Big energy steps in

Off-grid electrification: The International Energy Agency estimates that off-grid energy systems will receive 70% of the nearly $400 billion in investments required to provide energy access to the 1.1 billion people living without electricity. Utilities, oil, and gas firms and other large energy companies are increasingly taking notice of the opportunities in off-grid electrification through investments and acquisitions.

Two sides to tracking

Bifacial trackers: Solar tracker makers are bringing specially designed models to the market in order to embrace the coming wave of bifacial panels. While bifacial panels may capture up to 10% more light than monofacial panels, single-axis trackers typically add 25% to that bifacial gain, resulting in a roughly estimated 12.5% gain from the two technologies combined, compared with fixed installs using monofacial panels.
