This week, Women in Solar Europe (WiSEu) gives voice to María del Puy Ayerra, Head of Business Development Iberia at Spain’s Zelestra. She encountered isolated experiences that reflected subtle gender bias – particularly the assumption that women in leadership must adopt a “tough” character to survive in a male-dominated environment. “These stereotypes can be limiting and disheartening, especially for women who lead with empathy, collaboration, and strength of vision,” she states.

Guatemala has launched a 1.4 GW energy auction for renewable and low-emission projects to secure 15-year capacity contracts starting in 2030.

The Germany manufacturer said its new heat pump systems use propane (R290) as the refrigerant and are able to provide a maximum flow temperature of 70 C. Their coefficient of performance ranges from 4.7 to 5.1.

The off-grid solution includes module optimizers, an inverter, a battery, and an automatic transfer switch.

Spain now has 65.8 GW of solar projects with grid-connection permits, says the country’s energy agency. Total renewable energy installations with grid permits hit 129.5 GW by the end of March, up 15.5% from February.

Scientists have developed a system that harvests rainwater running off PV panels for household use or hydrogen production. Their analysis showed that, in the southern Sahel, the system can meet both the energy and water requirements for electrolysis, with surplus rainwater covering up to 50% of a household’s daily water demand.

Off-grid solar investment fell 30% in 2024, with early-stage firms and productive-use tech hit hardest, says Gogla. The global association for the off-grid solar energy industry adds that scale-ups attracted 77% of the nearly $300 million invested, signaling stronger commercial viability among mature players.

Austria has opened applications for its €60 million ($68.3 million) rooftop PV rebate program for 2025, with a second-round “Made in Europe” bonus offering 20% more funding for projects using European-made components, says OeMAG.

Wood Mackenzie warns that policy uncertainty could significantly alter its projections for US solar industry growth. The research firm says the US solar industry will add 502 GW (DC) of capacity over the next decade, with annual installations surpassing 40 GWdc through 2035.

GoodWe BIPV has identified new applications for its Vela residential solar carport. The modular unit is gaining traction in rural and small commercial settings in Australia as an alternative to ground-mounted and rooftop PV systems.

The tandem device is based on a bottom thin-film heterojunction cell that can bend and a top perovskite cell that can be manufactured with a low-temperature process to prevent damage. It achieved the highest efficiency ever recorded to date for a flexible perovskite-silicon tandem solar cell.

Sunwoda’s MESS 2000 mobile energy storage vehicle redefines the role of mobile power—evolving from a tool for emergencies to a key player in everyday energy supply.

Chinese manufacturer Das Solar says it will open its first European PV panel assembly plant in Mandeure, eastern France, by the end of 2025.

The Spanish manufacturer will exhibit the E/Xpand HV battery at the upcoming Smarter E show in Munich next month. It will showcase racks for commercial and industrial (C&I) and large-scale systems of up to 5 MWh.

Researchers in Italy have designed a novel carbon dioxide heat pump that can work with photovoltaic-thermal energy, a finned coil heat exchanger and a U-tube borehole heat exchanger. Their experiment has shown that the simultaneous use of at least two energy sources always results in improved system performance even with limited heat transfer areas.

Enphase Energy has posted $356.1 million in revenue for the first quarter of 2025, falling short of expectations. The solar microinverter and battery storage provider says it has lowered its margin outlook due to rising tariff pressures.

The Japanese automotive components and systems manufacturer began testing its proprietary organic perovskite solar modules in what will be a 30 kW outdoor field trial at one of its facilities in Anjo.

The Indian manufacturer said its new n-type TOPCon bifacial solar module has a a power output of 585 W to 620 W and the same compact dimensions as a traditional 550 W panel.

Toyo Co. has started production at its 2 GW solar cell facility in Ethiopia, with plans to deliver more than 80 MW of tunnel oxide passivated contact (TOPCon) cells by the end of April before scaling capacity to 4 GW.

Researchers at the Delft University of Technology have developed a top-down processing method localized the front contact in heterojunction solar cells. The new technique reportedly improves a cell’s short-circuit current density enabling higher power conversion efficiency.

Dutch energy storage firm Return has started construction on the 100 MW/200 MWh battery energy storage system in Waddinxveen, which will be the first project of the size to connect to the TenneT Netherlands high-voltage network in 2026. Vattenfall will manage and optimize half of the system’s capacity under an eight-year contract.

The Trump administration’s China tariffs have piled atop existing and developing trade barriers on battery energy storage systems, components, and materials – destabilizing the US energy storage industry. While existing inventories will allow project development to move forward in the short term, uncertainty extends across the supply chain, including to prospective manufacturers.

Aurora Energy Research says the global electrolyzer pipeline now totals around 1.3 TW, with 114 GW in development and 32% expected online by the end of 2026. The firm cites stronger EU policy support and growing momentum in hybrid power purchase agreements (PPAs).

New research from Germany shows that home batteries have much lower chances of being hit by fire than electric vehicles and most home appliances. The researchers warned, however, that fires in residential storage systems can be more dangerous than those of burning tumble dryers.

Adani Green Energy has signed an agreement with Uttar Pradesh Power Corp. Ltd (UPPCL) to deliver 1,250 MW of energy storage capacity from pumped hydro storage projects.
