Plant Performance

With solar operations and maintenance experiencing significant price pressure, adequate fault detection that occurs as quickly as possible has become increasingly important for asset operators. Here, 3E’s Julien Deckx explores early fault detection strategies for solar PV plants.

Last year analysis by renewables performance aggregator and insurance provider kWh Analytics highlighted the extent of solar asset underperformance against P50 estimates in the US. Here, the company’s Sarath Srinivasan details some of the reasons behind that underperformance.

As operational solar assets mature, news of repowering projects is steadily ramping up. Alice Grundy takes a look at what’s influencing decisions and just when the right time to repower is.

As solar finds itself deployed in more exotic climes, it is also having to operate in increasingly harsher environments. Ulrike Jahn of VDE Renewables and Dr. Bert Herteleer of KU Leuven assess how such climates affect PV performance and what must be taken into consideration when formulating O&M strategies.

The 2021 edition of PV Evolutions Labs’ Module Scorecard saw a record number of module manufacturers recognised, but equally highlighted a growing incidence of module failure rates. Liam Stoker unpicks some of the key trends from this year’s edition of the scorecard.

Pressures on PV plant performance have led the solar industry to be more demanding and forensic of the data operational projects generate, as well as the power. Jules Scully explores the growing role software is playing in the utility-scale solar arena and how it must evolve further still to meet expectations.

As solar finds itself installed in further flung climes, so it must operate in harsher conditions. PV CAMPER, a collaborative effort including some of the world’s leading academic and research institutes, has set itself the aim of uncovering data to help drive the industry forward. Here, members of PV CAMPER discuss some of their preliminary findings.

With extreme weather events becoming increasingly common, Molly Lempriere takes a look at how to ensure a solar installation is prepared to manage wind, hail, heat and anything else nature has in store.

The cost of insuring operational solar farms has skyrocketed over the course of the year, triggered by carriers rethinking their approaches to natural catastrophes and other extreme weather events. This has placed additional importance on mitigation strategies. Kevin Christy, COO for North America at Lightsource bp, details how the solar developer has adapted its strategy in the field.

As it matures, the solar industry is moving beyond the use of Performance Ratios (PR) as the go-to performance metric for operational sites. Christopher West, head of central engineering - solar PV delivery unit at Statkraft, argues the case for PRs to be replaced by alternative, more evolved methods of assessment.
