Digital tool to monitor PV plant construction

U.K.-based Above has developed a digital approach to unifying PV plant testing and inspection data. The company said the new tool can create a permanent digital record for the future.

Study of 100,000 arrays finds proactive O&M preferable

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.

Nextracker unveils new software for solar park monitoring

The U.S. tracker provider has launched NX Navigator, a control system it says offers improved monitoring across a range of weather conditions. The company claims the software enables PV plant operators to schedule maintenance operations such as cleaning and mowing.

Canadian researchers have done the math on optimizing PV output

Mathematicians at Canada’s University of Waterloo who turned their attention to solar power have developed an algorithm they say offers better control over PV plant output. The researchers estimate the algorithm could improve the output of a 100 MW power plant by almost a million kilowatt-hours per year.

Troubleshooting efforts in PV plants: follow up Q&A from the recent pv magazine webinar

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. In a recent pv magazine webinar, experts discussed four troubleshooting cases and explored whether module-resolved monitoring would help reduce the effort, and thereby decrease LCOE.
