Correct.... On average, a household consumes around 800 to 1,000 kWh of electricity per month. This is to penalise those energy hogs and wasting electricity.
With solar, even hard to go above 500 as consumption is usually only after sun set.

Domestic consumers with a monthly electricity consumption of 1,500 kWh or below will not experience an increase in electricity tariff. This accounts for 99% of domestic consumers in Peninsular Malaysia.
