TOPCon cells lose less output in heat than older PERC cells, which matters on Indian rooftops in summer. This panel’s -0.31% per °C temperature coefficient and 22.4% efficiency mean more power from the same roof area.
It suits small roofs and business rooftops where every square foot counts. It usually costs a little more per panel than PERC, so compare the cost per watt, not the price per panel.
