Soiling and solar: No two solar plants are ever the same, and the conditions that can impact energy yield can literally change with the wind. Soiled solar modules had long been considered a minor nuisance for the sector, but as understanding of how soiling affects output improves, so have techniques and technologies to tackle the persistent problem of dirty modules.
Series troubleshooting: Individual insulation failures are often difficult to detect in monitoring. And when such problems are suspected, it is an additional challenge to pinpoint them precisely. In this series of realistic cases, pv magazine aims to make the estimation of troubleshooting efforts more concrete and to stimulate a discussion on today’s troubleshooting efficiency.
Toshiba has posted a group net loss of JPY 49.8 billion ($439.5 million) for the first half of the current Japanese fiscal year, but the bleak outlook for its solar operations is the least of its concerns, as it struggles to cover losses from its bankrupt U.S. nuclear business and avoid being delisted from the Tokyo Stock Exchange (TSE).
Series troubleshooting: Bypass diodes fail regularly, either because they do not have a high enough power rating or because they are overloaded due to nearby lightning strikes. With the following hypothetical, but realistic case pv magazine starts a series which aims to make the estimation of troubleshooting efforts more concrete and to stimulate a discussion on todays troubleshooting efficiency.
There is a solid business case to combine PV plants with electrolyzers, as generation costs are low enough to competitively produce hydrogen as a fuel, says Bjørn Simonsen of NEL Hydrogen. He will speak at pv magazine’s Future PV event at SPI in Las Vegas.
Country’s Directorate General of Anti-Dumping states that it has identified a causal link between dumping and injury of Indian firms, enough to warrant the initiation of the investigation.
