Power to the people

By Liam Stoker, Solar Media

The UK’s energy retail market is witnessing an exodus of customers leaving the so-called Big Six for independent suppliers, who are attracting them with home solar systems and a battery to match. Liam Stoker uncovers what’s behind the trend for new energy suppliers taking to domestic PV.

Corporate takeover: the end of independence?

By Andy Colthorpe, Solar Media

The growth potential of energy storage has drawn interest from some of the biggest names in the power business and beyond. With the trend set to continue, Andy Colthorpe explores how three of the recent targets are faring under new ownership.

Easing the risks of battery investment

By Dr. Davion Hill, DNV GL

As the building blocks of energy storage systems, batteries have a key role in influencing system design and economics. Davion Hill of DNV GL explores the importance of testing the performance of individual battery cells in minimising the exposure of battery buyers to technical risks.

Solar asset management: why it needs to evolve

By Ypatios Moysiadis

Asset management practices must mature and standardise to keep pace with the rapidly accelerating deployment of solar. Ypatios Moysiadis, vice-chair of an industry group tasked with drawing up new best practice guidelines, explains how.

Reflecting on ways to boost module output

By Sara Verbruggen

Anti-reflective coatings have been a standard technology on solar modules for some time, but several companies are now targeting the market for older solar farms. Sara Verbruggen reports on the promising early results from trials of these performance-boosting technologies.

Project briefing - Europe’s flagship post-subsidy project up close

By Tom Kenning, Solar Media

It is ironic that Spain, whose government is infamous for its history of damaging PV policy U-turns, is also now home to the figurehead project of large-scale solar’s return in Europe after years of hiatus. The Don Rodrigo project in the southern region of Andalusia is the first mega-scale PV system to go without subsidies on the continent, standing at 175MW capacity.

Bifacial can smash its own glass ceiling

By John Parnell, Solar Media

Having suffered from a chicken and egg status, bifacial solar is making ground and the advent of single-glass modules could lower costs and tip the odds in 2019. John Parnell reports.

A tested and proven wind mitigation strategy to minimise risk

By Todd Andersen, Chief engineer, Array Technologies.

Ensuring the stability of solar tracking systems and modules during wind events is one of the top concerns of solar site owners, project developers and EPC contractors. A poorly designed single-axis tracker can result in damage to solar trackers and modules, leading to costly downtime, insurance claims, or even possible injury. Todd Andersen outlines the innovative methods that engineers at Array Technologies have uncovered and use to address this major potential setback for solar projects.

Weathering the storm

By Joseph Goodman; Frank Oudheusden

Hurricane-strength winds are a clear threat to solar installations in island nations, where PV is becoming an increasingly popular solution to climate change-related issues. Joseph Goodman and Frank Oudheusden, co-authors of a recent study on designing hurricane-ready solar systems, offer an insider’s view of how the challenge is being met.

The changing face of European solar

By PV Tech Power staff

Recent signs suggest that after several quiet years, large-scale solar is once again showing strong growth in Europe in spite of the steady withdrawal of subsidies. PV Tech Power caught up with six energy finance experts from the law firm Norton Rose Fulbright for the their take on some of the market and financing trends that will shape European solar in the years to come.

Achieving 100% renewables: supply-shaping through curtailment

By Karl A. Rábago; Marc Perez; Morgan Putnam; Richard Perez

How best to bridge the gap between the production of renewables such as solar and demand is the subject of much debate. Marc Perez, Richard Perez, Karl R. Rabago and Morgan Putnam argue the case for curtailment combined with storage as a cost-effective solution.

Financing emerging solar: A-listers speak up

By José Rojo, Solar Media

Development and private capital is fuelling a solar boom across the Earth’s four corners, from India to South Africa and Mexico. Five finance heavyweights walk José Rojo through their learnings so far and their future plans to tap into an industry they see as key to a better world.

Colombia at the crossroads

By José Rojo, Solar Media

Bogotá seems ready to kickstart its dormant renewable sector to bolster a hydroreliant power mix but auction delays suggest the road may be bumpy. José Rojo explores the factors behind the country’s slower PV awakening as Brazil, Mexico and other neighbours surged ahead.
