The Elan Shine 540 W is a mainstream choice for rooftops that need the PM Surya Ghar subsidy. It uses Mono PERC half-cut cells with a dual-glass bifacial build, so the back of the panel adds a little extra output on reflective roofs.
At 540 W, a 3 kW home system needs six panels, which fits most terraces. Ask the installer for the DCR certificate and check the model on the current ALMM list before you pay, because the subsidy depends on both.
