Colombia’s new government puts $1.35 billion solar program for low-income households under review

Colombia’s new energy minister has placed the Colombia Solar program under review, citing a lack of progress on a COP 4.2 trillion ($1.35 billion) agreement that currently has “zero connected users.” The review comes as Colombia and the United States deepen energy cooperation through new agreements on strategic minerals and civil nuclear technology.

From more than 50 GW to under 10 GW: Ukraine doesn’t need its old energy system back

Six air-raid alerts on the first day, backup generators on almost every street corner, and discussions about the rapid reconstruction of severely damaged energy infrastructure: my trip to Kyiv and Lviv showed me why decentralized solar and energy storage are far more than climate technologies for Ukraine. They are part of the country’s security architecture. They also underscore why German solar companies should be engaging with Ukraine today.

Italian solar redrew the day, but gas still sets the price

Solar growth softened Italy’s midday power squeeze in summer 2026, but higher heat-driven demand and weaker hydro and wind left gas to cover most of the 7.9 TWh supply gap. The result was a sharper evening exposure: gas generation surged, prices rose most after sunset, and solar-heavy southern zones increasingly faced midday oversupply and weaker capture rates.

Reliability risks emerge across BIPV, floating PV and agrivoltaics

A new IEA PVPS Task 13 report identifies distinct reliability risks across BIPV, floating PV and agrivoltaics, from heat and partial shading to wave loads, ammonia exposure and soiling. It argues that existing PV qualification standards do not fully capture these application-specific stresses, requiring adapted testing, design practices and performance metrics.

Fighting coastal corrosion

Salt in the air can wreak havoc with projects that lack the necessary corrosion resistance, proving costly for asset owners or the engineering, procurement and construction (EPC) companies that built them. Alexander Gebert, sales director at Tobsteel, argues that quality stainless steel fasteners can save costs for solar investors and engineering, procurement and construction (EPC) contractors in the long run.

Heterojunction’s long road to the US solar factory

For a cell technology that has spent much of the past three decades on the verge of a breakthrough, heterojunction (HJT) is enjoying another moment in the spotlight. This time, however, the setting is somewhat unexpected – rather than the established manufacturing centers of China and Southeast Asia, some of the most significant new commitments to HJT are emerging in the United States, Finlay Colville reports.

Ireland’s leap of faith to power data centers

Under Ireland’s Large Energy User Action Plan (LEAP), 10 MW-plus data centers must provide at least 80% of their energy demand through new onsite renewable energy generation and storage. But whether data centers can meaningfully contribute to Ireland’s decarbonization depends on the success of its grid buildout, reports Blathnaid O’Dea.

France connected 3 GW of new solar capacity in the first half of 2026, slightly above the 2.9 GW deployed in the same period of 2025. Large-scale installations above 500 kW accounted for 28% of newly connected capacity, despite representing just 0.3% of new connections. Systems below 9 kW dominated installation numbers, accounting for 78% of new connections but only 8% of added capacity.
