A new report published by the European Technology and Innovation Platform outlines the need for continuing research into the reliability of PV systems and components, and for the collection and sharing of performance data. The report recommends a holistic approach to reliability, going beyond current testing standards to identify new degradation mechanisms, and making use of sensors and drone imaging to monitor systems in the field to prevent and report on system failures.
International researchers have developed data quality routines to ensure data fidelity in O&M practices. They reconstructed invalid data through a sequence of filtering stages and inference techniques.
U.S.-owned business intelligence firm Wood Mackenzie has attempted to evaluate the market opportunities offered by the repowering of solar projects around the world which feature inverters which are 10 years old – as well as those which will expire ahead of time.
In a recent interview with pv magazine, Supreeth Srinivasa Rao – associate director of the industrial practice at Frost & Sullivan – explained how drones can minimize the need to send employees to project sites, as they can be deployed for monitoring, operations, and maintenance purposes.
Amid the current disruption impacting renewable energy markets worldwide, solar power is proving to be a robust energy source. In China earlier this year, solar was the only form of energy generation that saw an increase in production from the previous year – rising by 12%. In this context, it’s becoming more important now than ever before for solar asset owners to recognize and take advantage of specialized solar software which can help mitigate business disruption in unexpected events and optimize long-term returns.
The US National Renewable Energy Laboratory examined five-year data to observe the most common system failure points and how to prevent them. Researchers considered residential, commercial and utility scale plants and found interesting results. While failures cannot be avoided completely, a key takeaway was that close monitoring and timely repair can effectively mitigate the financial effects of failures.
This year will see strong growth for the global PV market, to 114 GW, and that pattern will continue in the years ahead, according to analyst Wood Mackenzie. a report has highlighted soaring inverter replacement costs for PV project owners as a side-effect of the solar success story.
