Battery ESS (Solar Panel Battery Storage)

A battery (Electrical Energy Storage System) works hand in hand with your solar PV system to store any excess solar instead of putting it back into the grid.

Battery ESS  

When the sun goes down, it’ll supply power to the house and eliminate the need to draw electricity from the grid. 

A solar PV installation is not required to maximise the benefits of a battery storage system. 
With the use of an off-peak tariff, a huge saving can be achieved.

What are the benefits to having battery storage?

Battery storage, in the context of energy systems, refers to the use of batteries to store electrical energy for later use. There are several benefits associated with battery storage: 


  • Energy Storage and Grid Stability: 

Load Balancing: Batteries can store excess energy during periods of low demand and release it during peak demand, helping to balance the load on the electrical grid. 

  • Grid Stability: Batteries can provide rapid response and support to the grid by stabilising frequency and voltage fluctuations. 

Renewable Energy Integration: 

Intermittency Smoothing: Renewable energy sources like solar and wind are intermittent. Battery storage helps smooth out the fluctuations in power generation, making it more reliable and consistent. 

  • Energy Independence: 

Backup Power: Battery storage systems can serve as backup power during grid outages, ensuring a continuous power supply for critical applications or in areas with unreliable grid infrastructure. 

  • Peak Shaving and Demand Management: 

Reducing Peak Demand Charges: Businesses and utilities can use battery storage to reduce peak demand charges by drawing stored energy during periods of high demand instead of purchasing expensive electricity from the grid. 

  • Time-of-Use Savings: 

Optimising Energy Costs: Battery systems can be used to store energy during low-cost periods (e.g., at night) and discharge during high-cost periods, allowing consumers to optimise their energy expenses. 

  • Grid Infrastructure Optimisation: 

Reducing Transmission and Distribution Constraints: Batteries strategically placed in the grid can alleviate congestion in transmission and distribution systems, reducing the need for expensive infrastructure upgrades. 

  • Emissions Reduction: 

Clean Energy Storage: Pairing batteries with renewable energy sources contributes to reducing greenhouse gas emissions, as stored energy can be utilised when renewable generation is low. 

  • Voltage and Frequency Regulation: 

Fast Response: Batteries can provide rapid and precise response to changes in voltage and frequency, contributing to the stability of the electrical grid. 

  • Remote and Off-Grid Power Supply: 

Islanded Systems: Battery storage is crucial in remote areas or off-grid locations, providing a reliable power supply without the need for extensive transmission lines.
