PV Tech Power Papers

Datasets from multiple sources allow PV power plants to be monitored more closely than ever before, but how best to use this data is another ball game. Edmée Kelsey and Gwendalyn Bender look at how data should best be stored, managed and mined for effective solar asset management.

With either newly built PV plants or plants in operation for a couple of years, an O&M contractor may face a series of issues related to the plant’s design and construction, the quality of the equipment and parts, and warranty claims. Vicente Parra and Gorka Oña highlight some of these issues and recommend how O&M contractors can address them.

The renewable energy market is currently booming, with large numbers of PV systems being installed throughout the world. However, a primary objective of any PV power system is to ensure that the system operates continuously and reliably. As Vicente Salas from the Universidad Carlos III de Madrid (UC3M) explains, this aspect takes on special relevance in the case of utility-scale PV projects.

PV modules are subjected to various loads during installation handling. Research teams from the Institute for Solar Energy Research Hamelin (ISFH) and Hanwha Q CELLS attended the installations of PV modules in order to develop various test sequences for quantifying the effects of handling loads on the modules. As a result of these observations, lab tests have been designed to evaluate the impact of module-handling loads on cell cracking in the modules. Some rules for module handling are subsequently proposed.

Accurate forecasting is becoming increasingly important as PV penetration grows. Jan Remund of Meteotest looks at some of the recent developments in forecasting science and the work going on to improve this vital aspect of solar’s interaction with the grid.

It was a turbulent year for solar finance in 2015 with big successes, more innovation and a few nasty surprises too. Mercom Capital’s Raj Prabhu takes a forensic look at solar finance in the last 12 months and the clues offered for the year ahead.

Solar’s widely heralded shift to self-consumption models has failed to happen to any meaningful degree. But as it remains PV’s only viable future business model, it’s time to get the project back on track, writes Gaëtan Masson.

As the economics of solar improve, merchant projects are already in place in Chile and various parts of the US. However, as lawyers from Chadbourne explain, financing them is not a straightforward business.

An eight-page special report on the growth of solar in the MENA region, focusing on market opportunities, policy, technology, and operations and maintenance.

Securitisation is emerging as a promising new source of finance for the solar industry. Raymond Hudson looks at its potential for future growth and some of the considerations for developers looking to go down the securitisation route.
