What is solar energy storage?
What are the main battery storage applications?
Battery storage can be used in many ways that go beyond the simple emergency backup in the event of an energy shortage or blackout. Applications differ depending on whether the storage is being used for a business or a home.
For commercial and industrial users, there are several applications:
- Peak shaving, or the ability to manage energy demand to avoid a sudden short term spike in consumption
- Load shifting, which allows businesses to shift their energy consumption from one time period to another, by tapping the battery when energy costs more
- Flexibility, whereby customers can reduce their site’s grid demand at critical times – without changing their electricity consumption. Energy storage therefore makes it a lot easier to participate in a Demand Response program and save on energy costs
- Microgrids rely on batteries as a key component, because these grids need energy storage to enable them to disconnect from the main electricity grid when needed
- Integration with renewable energy sources, since batteries guarantee a smooth and continuous electricity flow in the absence of the availability of power from renewable.
Residential users benefit from battery storage applications by:
- Self consumption, since residential users can produce solar energy during the daylight hours and then run their appliances at home at night
- Emergency backup in the event of a blackout
- Going off the grid, or detaching completely from an electrical or energy utility
What are the battery energy storage benefits?
- Environmental gains
Installing a battery storage system in a home or businesses powered by renewable energy reduces pollution, thereby contributing to the energy transition and combating the effects of global warming.
- Lower energy costs
Storing low-cost energy and consuming it during peak periods when electricity rates are higher allows a user to shift consumption and avoid higher charges, saving money. The savings are magnified when combined with solar power, which is free.
- Less dependent on the grid
Battery storage systems guarantee a continuous energy supply, even at times when the energy grid is unstable due to peaks in demand or extreme weather.
- “Always on” supply
The sun is not always “on.” A battery storage system works round the clock, and therefore compensates for any fluctuations in solar energy supply by storing any excess power in the system.
A battery storage system provides emergency backup in the event of a power outage, guaranteeing business continuity.
