Solar solutions company Onix Solar Energy, a subsidiary of Onix Renewable, has received an order worth ₹1.48 billion (~$16.54 million), from Vikran Engineering to supply 193,550 of 620 Wp non-Domestic Content Requirement (DCR) TOPCon solar modules.

Onix Solar will execute the order within three months of the receipt of the date of manufacturing clearance from Vikran Engineering.

In June this year, Onix Renewable offered ₹264 (~$3) per share to acquire 1.6 million equity shares of Onix Solar Energy for approximately ₹429 million (~$5 million).

Onix Renewable has delivered over 500 MW of projects, including wind, solar, storage, and hybrid systems. The company currently has a solar module capacity of 100 MW.

Many developers are opting for non-DCR components, stating that they will need the same amount of investment, or sometimes, even less, when compared to DCR modules.

As of May 2025, solar installers reported that DCR modules carry a premium of up to ₹12 (~$0.14) per watt over non-DCR modules. Many choose to proceed with non-DCR systems instead, accepting the loss of subsidy in exchange for quicker installations.

The average system cost of large-scale solar projects remained low in the third quarter of 2025, with cost reductions seen across all module technologies. Projects equipped with mono PERC DCR modules required roughly 24% more capital than those using non-DCR mono PERC modules.

In March this year, the Ministry of New and Renewable Energy issued the updated DCR norms for solar cells.

According to the revised guidelines, a solar cell based on crystalline-silicon technology will be considered domestically manufactured only if produced in India using an undiffused silicon wafer, commonly known as a black wafer. These wafers fall under Customs Tariff Head 3818, and all manufacturing processes used to convert them into solar cells must be carried out in India.

However, cells manufactured in India from an imported diffused silicon wafer, commonly called a blue wafer, will not qualify as domestically manufactured under MNRE programs.
