A sense of units and scale for electrical energy production and consumption …
Energy is a measure of power output over time (energy = power x time). So to calculate energy output in watt-hours we have to multiply our power rating by the number of hours our plant is running. For example, if we have a 1000MW plant, its maximum energy output in a day would be 24,000MWh (1000MW x 24 hours).

Solar Integration: Solar Energy and Storage Basics
Temperatures can be hottest during these times, and people who work daytime hours get home and begin using electricity to cool their homes, cook, and run appliances. Storage helps solar contribute to the electricity supply even when the sun isn''t shining. It can also help smooth out variations in how solar energy flows on the grid.
Storage, self-consumption and energy balance
Even with 100% self consumption, the customer may still draw some power from the grid. This can be avoided by adding more solar and storage to make sure all night-time load is covered. An oversized solar system may have less than 100% self consumption, even if the customer is not drawing any power from the utility.
