there are two and a half million of these panels at kamuthi. estimated to make enough power for three quarters of a million people. they are squeezing every last drop of energy out of whatever sun is available. bi—facial panels even generate power from light that bounces back from the ground. or, even better, snow! not that there's much snow in southern india, nor reliable all year round rain. where water is scarce, washing dust covered panels can be impossible. an israeli company has developed a robot which dry—cleans the panels so they get a regular dusting. as the light fades, so does the power generated. until they've got the batteries to store something like the 648 megawatts kamuthi produces, solar in india will not replace dirty coal, the noxious gases from which pollute the country and the rest of the world. it's certainly getting cheaper, this week, wholesale prices of solar dropped below coal for the first time. india is aiming to get it solar capacity up from 12 to 100 gigawatts in five years. bids are in to construct a bigger plant
