Brazilian energy storage hampered by technical challenges, lack of regulation
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.
How albedo interacts with different rooftop PV system patterns
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.

Sierra Space adds production capacity for solar power systems for satellites
The U.S.-based commercial aerospace and defense technology company, announced a new $45 million facility in Colorado to manufacture solar array systems to serve the growing satellite market.
‘It’s not enough to open doors, we must ensure women are supported once they’re inside’
This week Women in Solar+ Europe gives voice to Yana Hryshko, Managing Consultant, APAC, Head of Global Solar Supply Chain Research at Wood Mackenzie. She says that PV industry in China the gender divide, while still present, feels less rigid than in Europe. “Women are active across various departments, including engineering, manufacturing, QA, sales, and research,” she states. “Although men remain the majority, the gap feels narrower than in Europe.”
Solar records in UK and Germany as cold snap hits Eastern Europe
In a new weekly update for pv magazine, Solcast, a DNV company, reports that record irradiance in western Europe boosted solar output in May, while low pressure and Arctic air suppressed irradiance and temperatures in the east.
Wafer producers scramble to stay afloat despite hydropower advantage
In a new weekly update for pv magazine, OPIS, a Dow Jones company, reports that FOB China wafer prices remained stable this week amid weak demand and low production. It says manufacturers continue to face margin pressure despite seasonal hydropower cost relief and traceability documentation premiums.
French company offers router capable of redirecting surplus solar to water heating
French energy cooperative Solarcoop has launched a solar router that redirects surplus photovoltaic power from self-consumption systems to electric water heaters or other resistive loads, and can also control additional devices such as heat pumps.
