Extreme wind events are the biggest cause of failure and insurance claims for any PV plant, according to Thorsten Kray, Head of the Building Aerodynamics Department at Institut für Industrieaerodynamik GmbH, Aachen. For structural reasons, single-axis trackers are more prone to the issues than fixed-tilt structures. In this two-part series, pv magazine will examine the ways that wind impacts trackers and what EPCs and investors need to look out for, in addition to outlining a range of approaches from big tracker suppliers that were designed to mitigate wind-related damage.

According to the latest market forecast published by Wood Mackenzie, it seems that global PV installation figures will rise to 125 GW per year from 2020. Continued global capacity expansion will come in through a growing gigawatts-club.

With PV’s cost declines, the growing question is: where to put it all, particularly in densely populated areas. Ingenuity to the rescue – a technology that took its first steps in 2007 is entering full market maturity. And its potential is rather impressive.

The German giant – which manufactures central inverters near Mumbai – announced plans last week to acquire Kaco and start a new smart infrastructure business from April 1. In light of those moves, pv magazine spoke to IHS Markit’s Cormac Gilligan about the new kid, albeit huge, on the block.

The French power electronics specialist is pulling out of the utility-scale segment to strengthen its profile in the residential and C&I space.

The amount and nature of desert dust determines whether daily cleaning of solar modules is a favorable option. However, frequent and water-intensive cleaning, as well as the amount of labor required, can be costly in desert installations. But the ingenuity of automation is on its way to help.

A new approach could extract carbon from polyethylenes in a cost-competitive way, that could be scaled up. Researchers have also performed electric testing with the extracted carbon and found it suitable for use as anodes in Li-ion batteries, among multiple other uses.

High solar irradiance and few cloudy days are ideal for solar. Fine dust and extreme heat is not – particularly when it comes to power electronics. As the distributed generation market segment emerges across hot climates, extreme conditions are a challenge inverter suppliers are grappling with.

The 95 MW project is part of a broader 260 MW generation capacity allocation the IPP received from Gujarat Urja Vikas Nigam Ltd. Generated electricity will be sold through a PPA between Azure Power and Gujarat Urja Vikas Nigam Ltd., at a rate of INR 2.67, for a 25-year duration.

The programme allows the installation of solar roof atop apartment blocks, which otherwise could not install such systems. Potential in the area is around 15 MW, of which 6 MW have been signed up for already. Another 5 MW should be developed in this second phase of the project.
