France’s collective solar self-consumption model hits regulatory wall
A roundtable recently held by solar panel manufacturer Dualsun and the GoodPlanet Foundation in Paris highlighted the organizational and regulatory barriers holding back collective solar self-consumption in France, a model its proponents say is technically ready to scale.
Solar industry faces rising risks from fires and battery faults
The 8th annual Solar Risk Assessment from kWh Analytics identifies equipment-driven fires, regulator fines, and battery inaccuracies as the latest threats to renewable asset returns.
The impact of fly ash-induced soiling on PV panel performance
Scientists in Morocco have conceived an experimental–numerical model to quantify how fly ash soiling affects photovoltaic (PV) modules, capturing both optical losses and thermal effects. Their findings show that while dust layers can reduce panel temperature, fly ash significantly degrades efficiency in a non-linear way, highlighting the need for predictive models for real-world solar performance.
Assessment of Nigeria’s agrivoltaic potential identifies northern states as optimal areas
A geospatial assessment of agrivoltaic potential in Nigeria finds greatest opportunity in the country’s northern regions with plentiful cropland, high solar irradiance and low electricity access rates. It calculated that meeting projected mid-century solar demand in the states of Kano, Katsina and Jigawa could be achieved by installing agrivoltaics on less than 1.5% of cropland.
Palestine launches program for local authority solar projects
A program designed to finance solar projects for local authorities in Palestine has opened with an initial $25 million investment from the Palestine Monetary Authority in collaboration with Austria, Finland and Norway.
Bhutan tenders solar projects for healthcare facilities
Bhutan has kicked off a tender to develop 12.1 MW of rooftop solar across 73 public healthcare facilities in the country. The initial deadline to submit expressions of interest is May 29.
K2 Systems releases new mounting systems for ground-mounted PV
The German manufacturer launched two mounting systems for utility-scale solar projects and small- and medium-scale installations, respectively. Both are designed to streamline installation with simplified components and modular layouts.
Angola switches on Africa’s largest off-grid solar-plus-storage park
The off-grid solar project, encompassing 31.85 MW of solar connected to 75.26 MWh of battery energy storage, will supply energy to over 90,000 people in eastern Angola.
Solar panels reduce thermal stress in dairy barns during critical afternoon hours
A study from China shows rooftop PV systems on dairy barns can significantly reduce roof heat flux and improve indoor thermal conditions. Field measurements and simulations found up to a 2.3 C reduction in indoor temperature during peak afternoon heat stress periods.
EU solar and storage push could cut power system costs by nearly half
A scenario analysis by SolarPower Europe, modeled by Rystad Energy, finds that accelerating PV and battery storage deployment could save the European Union €223 billion ($260.7 billion) in gas imports between 2026 and 2030 and reduce wholesale electricity prices by 14% compared with 2025 levels.
