The decision points that make or break solar projects
An IEA-PVPS report warns that treating technical and economic solar project decisions separately poses financial risks, advocating instead for cost-effective “quality gates” during early development. Through a structured decision matrix and real-world case studies, the report highlights how proactive planning—such as utilizing mobile testing labs and defensive weather strategies—prevents downstream failures and operational budget strains.

Blocking, El Niño and extreme events redistribute solar resource in 2026 so far
In a new weekly update for pv magazine, Solcast, a DNV company, reports that, in the first half of 2026, solar irradiance was broadly above average across Europe, the United States, Southeast Asia, South America, and Central Africa, driven by shifting atmospheric patterns transitioning from early-year blocking and polar vortex disruption to developing El Niño conditions. Elsewhere, conditions were more mixed: Canada, Mexico, South Africa, North Africa, parts of Western Russia and Central Asia saw 5–10% deficits, while Asia, Australia, and parts of the Americas experienced strong regional variability influenced by cloud, rainfall, cyclones, dust, and smoke events.

Who maintains Europe’s orphaned rooftop solar?
Europe added 65.1 GW of solar capacity in 2025. It also lost 40,000 solar jobs – the first workforce contraction in nearly a decade, according to SolarPower Europe. Behind those job losses is a wave of installer insolvencies that is creating a problem the industry has been slow to acknowledge: a growing population of residential solar systems with no warranty support, no maintenance provider, and no monitoring.

Documenting risk
PV projects rarely fail because of vision, permitting or demand issues. They fail because of missing proof. Documentation gaps are becoming a key source of financing and execution risk. Intertek CEA Chief operating officer Jeffrey Burkett sees a clear pattern across the market: technically sound and commercially viable projects are still unable to close financing. Not due to fundamental flaws, but because critical documentation was not built up along the way.

TÜV NORD study finds back-contact advantage over TOPCon is limited to mild shading conditions
A TÜV NORD study found that back-contact (BC) modules outperform TOPCon modules under mild partial shading, particularly when three or fewer cells are shaded across different substrings within a string. However, once shading exceeds four cells, the performance advantage disappears, with both technologies experiencing similar power losses of around 50%.
