Why India’s 300GW Solar Target Needs Secondary Copper — And Why Every Solar Panel Is a Future Copper Bank

Solar energy produces clean electricity. It is also built with copper — and more of it than most discussions of the energy transition acknowledge. A typical solar installation requires 5–6 tonnes of copper per megawatt — in wiring, inverters, earthing systems, and grid connections.
