Module cooling: too hot to handle
Even after the record-breaking heat waves of this summer and associated performance losses at PV plants across the northern hemisphere, active cooling for solar arrays remains a difficult market prospect. Developers might be a bit more interested in preventing temperature-related losses, but in most cases, the numbers still don’t quite add up.

Sodium-ion batteries: the next frontier or the next risk?
While sodium-ion offers a compelling long-term solution to flattening LFP cost curves and tight supply chains, its lack of field-validated performance data transfers significant technology and bankability risks directly onto developer balance sheets.

The case for vertical BIPV
A major IEA PVPS Task 15 study finds that vertical BIPV façades can complement rooftop solar with minimal yield penalties, smoothing generation across the day while offering greater design flexibility. Across 357 configurations in 44 cities, the research also shows BIPV economics improve substantially when avoided building-material costs are counted, with long-term viability shaped by electricity prices, financing, installation costs, and application type.

Weaker monsoon lifts irradiance in western India as August storms dim the east
In a new weekly update for pv magazine, Solcast, a DNV company, reports that northwestern and southern India and Pakistan recorded above-average solar irradiance during the 2026 summer monsoon, benefiting major PV-producing regions, while tropical depressions drove irradiance sharply below average across eastern and central India. Favorable solar conditions helped support Indian PV generation and electricity exports to Nepal after late-August floods damaged hydropower plants and other energy infrastructure there.

Everything’s bigger in Texas
By almost any measure, the story of solar power in Texas has been one of astounding success. The state is by far the country’s fastest-growing solar market. The Solar Energy Industries Association (SEIA) records nearly 54 GW of solar and more than 29 GWh of batteries have been installed, while Texas is also growing into a vital hub for the US solar manufacturing industry, as Ben Zientara reports.

Peeling back the layers
As part of a PV module’s construction, front and rear encapsulants are used to bond solar cells to the front (typically glass) and rear (glass or polymer backsheet) surfaces. When these components degrade, delamination or bubbles can occur, opening new channels for moisture and oxygen ingress, drastically accelerating other failure mechanisms such as cell metallization corrosion.
