Ghana, Switzerland partner on $200 million rooftop solar rollout
Ghana’s new clean energy program, backed by Switzerland’s Klik Foundation, will install 4,000 rooftop systems totaling 137 MW to expand renewable capacity and cut emissions.
China’s new auction system drives steep solar price declines
Wood Mackenzie says first provincial auctions under China’s new pricing rules pushed solar bids up to 32% below settlement, signaling tighter margins and a shift to slower, more sustainable growth.
French startup launches cleaning robots for solar PV shade structures
Solar panel cleaning equipment company Objectif Drone has launched a new 7 kg dual-brush cleaning robot with a speed of 5 km/h made for small and medium-sized PV installations.
Europe faces surge in negative power prices as solar output grows
Sweden, the Netherlands, Germany, Spain, and France have each logged more than 500 hours of negative electricity prices this year, driven by excess renewable generation and volatile weather.
Bahrain to host world’s largest single-site rooftop solar power plant
A power purchase agreement is in place for a 123 MW solar project in Bahrain that will span 14 sites including the world’s largest rooftop solar installation, a 50 MW system on top of a 262,000 m2 stockyard shed.
GoodWe debuts PV-driven heat pump water heaters
The Chinese manufacturer said their new residential heat pump water heaters deliver a coefficient of performance of up to 4.2, with a heating capacity ranging from 4.5 kW to 5 kW. The units are available with water tanks in 200 L, 300 L, and 500 L sizes.
France revises off-peak hours to match solar generation patterns
French grid operator Enedis will shift off-peak hours to daytime periods to align power demand with rising solar output and reduce evening consumption peaks.
Crystalline silicon vs. thin film at high latitudes
A four-year analysis conducted at a testing field in eastern Poland has shown that crystalline solar panels offer a stronger performance than thin-film panels at high latitudes. The tests revealed pronounced seasonal variability across all technologies, with thin-film modules showing markedly lower capacity factors than crystalline silicon, particularly in winter.
Italy seizes solar investment portal over €80 million scam
The Italian authorities have frozen bank accounts and seized assets linked to a transnational network accused of defrauding about 6,000 investors through a fake PV investment scheme.
US rooftop solar’s climate gains shrink as grids grow cleaner
