Trina Solar unveils 485 W TOPCon PV panel with 24.3% efficiency
The Chinese manufacturer has launched its third-generation Vertex S+ G3 dual-glass TOPCon modules for residential and commercial applications. The new products feature upgraded module architecture and a temperature coefficient if -0.26% per C.
From panels to complete energy systems: The evolution of India’s rooftop solar market
Rooftop solar is moving from being a supplementary solution to becoming a central component of India’s energy architecture. The next phase of growth will not be defined by panel installations alone but by how effectively generation is integrated with storage, digital intelligence, and grid infrastructure.
DAS Solar unveils new method to identify hot-spots in TOPCon back-contact solar modules
The Chinese manufacturer said it developed a new circuit-model–based method to accurately detect hot-spot risks in TOPCon back-contact modules, overcoming limitations of the IEC 61215 approach caused by low shunt resistance. Validated through indoor and outdoor tests, the method predicts temperature rise under shading and reportedly enables faster, more accurate hot-spot risk assessment.

The real question for India: Should we chase the next technology or optimize global best practices?
By combining proven global practices with solutions designed for Indian conditions, offering choices for different customer needs, and continuing to invest in meaningful innovation, India can build a solar ecosystem that is resilient and inclusive.
The sustainability advantage: Why HJT’s low-temperature manufacturing process matters?
As adoption accelerates, the critical question is no longer simply how much solar capacity can be installed, but how clean and sustainable the manufacturing process behind it truly is. Heterojunction Technology (HJT) has become one of the most compelling answers to that challenge.
