Modules & Upstream Manufacturing

UNSW researchers have investigated the impact of two types of soldering fluxes on TOPCon solar modules under damp heat conditions and have found that “no-clean” soldering fluxes can cause severe corrosion of front silver-aluminum contacts. The researchers have also found that denser metallisation structures and lower aluminium content improve corrosion resistance.

Entrepreneur and investor Nikhil Kamath has invested INR 137.5 crore in Goldi Solar, a Gujarat-based solar PV module manufacturing company. The investment will enable Goldi Solar to expand its production.

The revised timeline for the implementation of the Approved List of Models and Manufacturers for Solar Cells (ALMM-II) offers temporary relief to solar developers amid persistent domestic cell supply constraints. However, it also introduces fresh regulatory challenges, particularly around tariff renegotiations for recently awarded projects, according to analysts at CareEdge Ratings.

In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.

Researchers in South Korea have demonstrated a lower temperature process for bifacial copper, indium, selenium (CuInSe₂) solar cells with a rear-side efficiency of 8.44% and 15.30% on the front. The device has been developed for applications in tandem solar cells.

ReNew Energy Global has reported a net profit of INR 5,131 million for the first quarter of fiscal year 2026 (Q1 FY26), marking a 13-fold increase from INR 394 million in Q1 FY25. A significant portion of the profit—INR 3,562 million—was contributed by external sales from the company’s solar module and cell manufacturing business.

The Chinese manufacturer said its new IEC 61215-certified rooftop PV module relies on a 30 mm aluminum frame and dual-glass construction that reportedly help it withstand extreme snow loads and wind pressure.

Ember Energy says China’s solar export market is shifting as more diverse global supply chains drive higher cell and wafer shipments, lifting combined solar product capacity 11% this year despite lower panel exports.

The investment package features a $200 million loan for the implementation of the project and a $50 million preferred equity investment. The approval is said to have been opposed by several members of IFC’s board of executive directors.

RenewSys has secured a seven-month supply agreement with Kosol Energie to deliver high-performance POE [polyolefin elastomer] encapsulants for 700 MW of solar panels.
