Kilowatts describe capacity; kilowatt-hours describe what you get. A 3 kW array in Delhi generates around 12 units on a good day, 4 on a heavily overcast one, and about 360 in an average month across the year.
Against a typical three-bedroom load of 500 to 600 units a month, that covers roughly two-thirds of consumption — but only if the timing lines up. Generation peaks between 10am and 3pm. Household demand peaks after 7pm.

Moving load into the sun
The washing machine, the dishwasher, the water pump and the EV charger are all schedulable. Running them at noon instead of at night converts export credits into avoided tariff, which is worth substantially more per unit. Households that make that change routinely see another five to eight percent come off the bill without spending anything.
Size to the year, not the summer
A system sized for peak May consumption over-generates for eight months. We size against twelve-month consumption and let banked credits handle the peaks.
