Germany recorded 141 hours of negative day-ahead electricity prices in June, just below the record set in May, bringing the first-half total close to the full-year figure for 2023.

Yang Bao, Trinasolar’s president of global sales and marketing, recently spoke with pv magazine about the company’s strategy for the solar and energy storage business.

Guyana has introduced a net billing program for rooftop PV systems up to 100 kW and for larger systems based on a customer’s maximum demand. It aims to expand distributed generation and reduce grid dependency.

Researchers in France have investigated how photovoltaic power generation can be combined with the growth of hyperaccumulating plants in disused, contaminated brownfield land and have found this combination could help increase the profitability of the so-called agromining – a plant-based approach to cleaning up contaminated environments.

China plans to install 253 GW of solar capacity and restore more than 670,000 hectares of degraded land by 2030 under a large-scale desert PV program in its northern and northwestern regions. It aims to curb desertification and expand renewable energy deployment.

Oversupply of lithium-ion battery precursor and active materials – and of lithium iron-phosphate (LFP) batteries, especially in China – has driven energy storage system costs down, fueling a record 330 GWh of battery energy storage system (BESS) shipments in 2024. Edward Rackley, head of the energy storage team at Business intelligence specialist CRU, shares his analysis.

10 kWh sodium-metal-chloride batteries will be build at new site in Lancaster, England. Start-up LiNa is targeting markets with harsh climates during initial rollout and intends to produce 100 kWh systems following 10 kWh trial projects.

While Brazil wastes billions of real on curtailment, the electricity sector is demanding urgent action on an energy storage capacity reserve auction which is now not expected until 2026. ‘What is missing is the courage to unlock the market,’ said Greener CEO Marcio Takata.

Sunkind Energy has signed a strategic technical partnership with JA Solar to support its upcoming 2.4 GW solar cell and 4 GW module manufacturing facilities in India.

Researchers have simulated 160 cases of PV rooftop installation in southern and northern Italy. Among changing parameters were size and type of the panels, as well as their roof cover rate. The considered albedos were 20%, 40%, 60%, and 80%, representing different types of roof materials.
