Planning tips for Visakhapatnam

Size panels for December, not for the yearly average. A system sized on the average falls short in the dullest weeks, which is when you most need it.
Dust, heat and shade cut output. Keep panels clean, leave air space under them, and avoid anything that shades them between mid-morning and mid-afternoon.
Ask installers for the inverter's continuous and surge ratings, the battery's usable capacity and chemistry, and the panels' total watts. Compare those numbers with your plan rather than the package name.
