Project briefing

By Tom Kenning

While Filipino policymakers pondered a controversial bill that would allow a solar company to set up a micro-grid and transmission franchise aiming to improve power supply across the country, a small town on the island of Mindoro was already enjoying round-the-clock electricity for the first time ever. The town of Paluan, situated in the northwest corner of Mindoro, the seventh largest island in the Philippines, dominated by an agricultural society and dubbed ‘the brownout capital of the Philippines’, is receiving power from Southeast Asia’s largest micro-grid, combining solar PV, energy storage and diesel technology.

Power plant wire management

By Samuel Truthseeker

Effective management of cabling in a PV system can greatly impact its lifetime maintenance requirements and thus profitability. Samuel Truthseeker of TECSI Solar looks in detail at the latest developments in wire management and highlights several reliability considerations.

Project briefing: Building Benban: Inside Egypt’s 1.6GW Solar Park

By Ben Willis

Amid reports of logistical and bureaucratic difficulties, Germany’s IB Vogt earlier this year became the first company to complete and energise one of the multiple projects that will eventually make up Benban, Egypt’s gargantuan solar park in the western desert governorate of Aswan.

Analysis of bifacial PV systems in the Middle East

By Dr. Chen Zhu; Dr. Songming Liu; Zhichao Wang; Dr. Qiangzhong ZHU; Dr. Jun Lv

PV systems incorporating bifacial modules require careful design and integration to maximise the additional yield they offer. Drawing on extensive field studies, researchers from LONGi Solar describe the optimum design of bifacial systems in the desert conditions of the Middle East, to which bifacial technology is especially well suited

Hurdles to widespread bifacial PV adoption

By Jenya Meydbray

Bifacial technology is seen by many as the shape of things to come for the solar industry. But how is it regarded by those on the frontline of choosing equipment that will result in the most profitable projects? Jenya Meydbray, VP of solar technology at Cypress Creek Renewables, offers an insider’s view

Both sides of the story

By Javier Guerrero

As described in the previous pages, tracking and bifacial technologies combined offer the prospect of higher energy outputs. Javier Guerrero, R&D manager at Soltec, one of the pioneers of bifacial tracking, explains some of the lessons the company has learned about optimising tracker design for bifacial modules

State-of-the-art bifacial module technology

By Dr. Hartmut Nussbaumer; Markus Klenk; Andreas Halm; Prof. Dr. Andreas Schneider

Bifacial technology promises significant reductions in the levelised cost of electricity for PV systems, and almost all major PV suppliers are already producing or planning bifacial modules. Hartmut Nussbaumer, Markus Klenk, Andreas Halm & Andreas Schneider give an overview of the currently available bifacial modules and cell technologies and adapted mounting solutions

Project briefing

By Tom Kenning, Solar Media

In April of this year, the Indian Prime Minister, Narendra Modi, drew scorn when he announced that every village across India had access to electricity. The reality that ‘electrification’ in government terminology meant that a mere 10% of households in any one village had power, was not made clear in the initial announcements.

Project briefing - Hero Launches India’s First Solar-Wind Hybrid Project

By Tom Kenning, Solar Media

Delhi-headquartered renewable energy firm Hero Future Energies has completed India’s first largescale solar and wind energy hybrid project in the state of Karnataka. The project at Kavithal, Raichur District, which included an existing 50MW wind farm, now has a neighbouring 28.8MW solar PV site to form a hybrid system.

The Most Efficient and Adaptable Solution Design for Bifacial Modules

Leading PV inverter manufacturer Huawei discusses recent technical developments to a better understanding of bifacial solar module PV power plants, using three recent case studies. These efficient PV modules need to be used with devices such as inverters to maximize value. Recently, many inverters and solutions that match bifacial modules have appeared in the industry. Which solution is the best match for bifacial modules? Based on a large amount of experimental data, this article describes the solution needed for bifacial modules.

Bifacial PV: comparing apples with apples sometimes does not make sense

By Dr. Radovan Kopecek; Dr. Joris Libal

Bifaciality is a complex area of PV technology and currently there is some confusion over what bifacial gains can be expected and how these transfer to system cost reductions. Radovan Kopecek and Joris Libal describe how bifacial gains are defined, what bifacial gains can be expected and what this means for real applications

Track to the future

By Ben Willis,

Technology | Falling prices have seen single-axis trackers become standard issue in utility PV plants in many parts of the world. As the tracker market becomes more crowded, manufacturers are developing increasingly sophisticated technologies to stay ahead of the game and support wider PV power plant innovation. Ben Willis reports

Module technology under the microscope

By Finlay Colville

Modules | PV module technology is more advanced and more varied than at any other time. Having pulled together a throng of senior PV technology experts for our PV CellTech conference, PV Tech’s head of market research, Finlay Colville, discusses with John Parnell the need to match these advances with a dedicated event this November.

Light-induced degradation newly addressed – predicting long-term yield loss

By Dr. Marko Turek, Dr. Marko Turek studied physics at the Dresden University and received his PhD in the field of condensed matter theory at the University of Regensburg. At Fraunhofer Center for Silicon Photovoltaics (CSP) he leads the team for the electrical characterisation of solar cells.

Module degradation | Light-induced degradation has long been recognised for its negative effects on the performance of crystalline silicon solar cells. Researchers from Fraunhofer CSP explain how with the advent of advanced materials and cell technologies such as PERC, new tests and standards are required to minimise the impact of the phenomenon on plant reliability.
