Published January 5, 2026. The Indian solar power industry is confronting a significant cost challenge as prices for critical raw materials like silver, copper, and aluminium have surged dramatically. This escalation in metal prices directly impacts the manufacturing of solar panels, wiring, and inverters, leading to higher production expenses for companies nationwide.
Metal Price Surge Hits Solar Costs
Silver prices have risen by one-and-a-half times over the past year, while copper has seen a 40% increase and aluminium prices have climbed by more than 20%. These global market-driven price hikes translate into increased input costs for solar component manufacturers. An executive from a solar power firm noted that these increases have impacted transformers, cables, and conductors, resulting in a 3-15% rise on end products.
Manufacturers Face Margin Squeeze
Gujarat-based Kosol Energie Pvt Ltd reported an 8-10% increase in solar module production costs over the last five to six months, with expectations of further hikes as Chinese suppliers also raise prices. Kalpesh Kalthia, CMD of Kosol Energie, stated that solar modules constitute approximately 50% of a project's cost. Vinay Thadani, Director & CEO of GREW Solar, highlighted that rising metal prices are tightening margins for manufacturers, compelling closer cost control and sourcing efficiency. Inverter prices are also slated to rise by 3-4%.
Mitigation Strategies Emerge
Industry players are actively seeking ways to counter the escalating material costs. Manufacturers are reducing silver intensity through advanced printing techniques, multi-busbar designs, and transitioning to newer technologies like hetero junction. Lighter frames and alternative structural designs are being deployed for aluminium components. Companies are also pursuing longer-term procurement contracts and exploring strategic sourcing options.
Future Outlook for Industry
While short-term margin pressures persist, and some manufacturers may absorb rising module costs, the industry anticipates a moderation in metal prices medium-term as supply chains stabilize. Vinay Rustagi, Chief Business Officer at Premier Energies Ltd, noted that improving technology and scale can help offset negative impacts, and solar power's overall cost advantage over other generation methods provides a buffer. The push for localized manufacturing also contributes to insulating the Indian market.
