If solar-powered irrigation pumps can be rolled out in a responsible manner at scale, the impact on agriculture in sub-Saharan Africa could be transformational.

As the world becomes increasingly roiled by extreme weather, drone-based electroluminescence (EL) mapping can be a key weapon in the arsenal of solar investors.

In a new weekly update for pv magazine, Solcast, a DNV company, reports that a significant high-pressure anomaly in the Pacific fostered more settled conditions and pushed a deep layer of dryer air over the Western United States, resulting in clearer skies. Whilst coastal regions saw average to slightly more irradiance than normal, Midwestern states including Iowa, Nebraska, Kansas, and Wyoming, received up to 110% normal levels.

In another article of a series, Women in Solar Europe (WiSEu) gives voice to Angelika Möbius, the founder of the startup Solar AI Twin. She says addressing the gender gap in the solar industry is a complex task that requires a deep understanding of the unique challenges women face. Key barriers include a lack of mentorship opportunities and the absence of professional networks.

In a new weekly update for pv magazine, OPIS, a Dow Jones company, offers bite-sized analysis on solar PV module supply and price trends.

Prices in the majority of major European electricity markets fell during the first week of May, according to analysis from AleaSoft Energy Forecasting. The exception was in the Iberian market of Portugal and Spain, but prices remain lower there than anywhere else.

Spanish developer Solaria says it bought 435 MW of solar modules from an undisclosed supplier for €0.917 ($0.99)/W. Kiwa PI Berlin confirms that average solar module prices for large-scale PV projects in Spain are now around €0.10/W.

The Ministry of Energy Transition and Water Transformation in Malaysia is teaming up with private and public partners in the country to offer citizens financial incentives and discounts when adopting solar. It follows a government rebate scheme introduced in April.

The new MLPE from Tigo is designed to support commercial and industrial as well as utility-scale solar projects.

Researchers at the Wuhan University of Technology in China               The system was described in the paper “Performance analysis of radiative cooling combined with photovoltaic-driven thermoelectric cooling system in practical application,” published in Energy.

Modeling shows that shifting just one-third of the electricity consumption of commercial and institutional buildings in Australia to the middle of the day, coinciding with peak solar supply, would create almost 12 GW of new peak capacity in the National Electricity Market.

State-owned utility Egyptian Electricity Holding Company is requesting expressions of interest for the design, building and operation of a 8.2 MW solar plant and 2 MW/4MWh battery energy storage system, located at the site of an existing microgrid in western Egypt.

Tests conducted by Canadian researchers at the NREL’s testing field in Colorado have shown that ground reflectors based on high-density polyethylene can significantly increase bifacial PV plant performance. They stressed the profitability of this technology is strictly dependent on the location and warned avoiding to combine it with inverter clipping.

The Chinese module manufacturer said the new efficiency record was confirmed by Germany’s Institute for Solar Energy Research (ISFH).

BSES Rajdhani Power’s new 20 MW/ 40 MWh project is India’s first utility-scale, standalone battery energy storage system to secure regulatory approval under Section 63 of the Indian Electricity Act, 2003. The project is supported by a concessional loan from the Global Energy Alliance for People and Planet (GEAPP).

A 4.4 MW solar project featuring modular PV technology from 5B has commenced operations in Australia. The project includes 2 MW/1 MWh of battery storage systems from UK supplier Aggreko.

A new mobile power generator that combines solar and renewable hydrogen to provide zero-emissions power for remote and off-grid applications has been unveiled by Australian startup H2PowerBox.

Researchers at Karlsruhe Institute of Technology (KIT) have developed a scalable two-step evaporation and inkjet process for perovskite thin-film solar cells. The new technique reportedly enables to build champion cells with the same efficiencies as those made with the spin coating process.

Solar panels are often tilted to a stowed position to prevent wind damage to utility-scale assets. Array Technologies introduced a passive stowing strategy that reportedly prevents unnecessary production losses.

The International Energy Agency (IEA) says that global solar cell and module manufacturing capacity grew by around 550 GW in 2023. It reports that around 80% of the global PV manufacturing industry is currently concentrated in China, while India and the United States each hold a 5% share. Europe accounts for a mere 1%.

Tongwei, Canadian Solar, TCL Zhonghuan and JA Solar all reported significantly higher profits in 2023.

Austrian manufacturer Sonnenkraft has developed a terracotta glass-glass module that aesthetically blends in with tiled roofs. It has an efficiency rating of 20.02%.

Scientists in Japan have investigated the impact of seasonal, metereological factors on solar plant performance and have found the average power generation inefficiency reached significant levels. The findings suggest that optimal site for power plants requires careful consideration of meteorological and geographical data.

A group of Chinese researchers has made a first attempt to integrate pumped hydro with compressed air storage and has found the latter may help the former to better deal with large head variations.

The US Department of Energy says it is aiming for “clean” hydrogen production costs of $2/kg by 2026 and $1/kg by 2031.

An “Australian first” demonstration of aggregated flexible demand in residential settings will be rolled out in South Australia, with the state’s principle electricity distributor to deliver smart energy upgrades for 500 households as part of a pilot program to coordinate power usage and support the grid.

A study led by Russia’s Skoltech and China’s HPSTAR suggests that rubidium and cesium additives could improve the efficiency of hydrogen batteries. Researcher Dmitrii Semenok tells pv magazine that “it is a question of changing the approach to the search for promising hydrogen storage materials.”

Sunrun, a US-based residential solar installer, says nearly 1,800 customers have already signed up to its PowerOn Puerto Rico virtual power plant (VPP). The program deploys stored solar energy from customers’ batteries to the grid, preventing power supply shortfalls on the island.
