Intertek CEA's Joerg Althaus examines some of the most commonly found tracking and racking defects in PV power plants.

Statkraft and 3E analysed 64 utility-scale PV plants, representing 2.1GWp DC capacity, with datasets spanning six months to five years.

'Advanced forecasting tools are already improving solar and demand predictions by over 30%,' writes Schneider Electric's Frédéric Godemel.

Without quality control, even expensive, high-precision radiometers can generate misleading data, according to Solargis' Marcel Suri.

PV projects operate close to technical and financial limits, meaning that inaccurate inputs can have performance and profitability impacts.

New data suggests the traditional assumptions behind hail stow modelling may be underestimating the likelihood of damage to a PV system.

Brett Beattie of Castillo Engineering looks at some of the key land grading work that can make multimillion-dollar differences to projects.

Marco Zaniboni and Juanma Fernandez of Sonnedix examine the key considerations in deciding whether to revamp, repower or retrofit.

US solar tracker manufacturer Array Technologies has announced that two of its tracking systems are compatible with 2,000V solar systems.

US tracker manufacturer FTC Solar has launched an automated 80 degree hail stow angle for its flagship 1P Pioneer tracker.
