HOME BATTERY STORAGE WITH EXISTING SOLAR PANELS
How Does a Home Battery Storage Work With Solar?
Home/Residential battery storage systems work by storing excess electricity generated by renewable energy sources (like solar panels) or purchased from the grid during off-peak hours. This stored energy can then be used later when demand is higher, during power outages, or when energy costs are higher.
Home battery storage systems work alongside solar panels to help homeowners maximize the use of the solar energy they generate. Here's an overview of how the system works with solar panels:
1. Solar Panel Energy Generation
Solar panels convert sunlight into electricity, producing direct current (DC) power.
An inverter converts the DC power into alternating current (AC), which is used by household appliances.
Real-Time Usage vs. Surplus
During the day, if your solar panels generate more electricity than your home uses, the excess energy is typically sent back to the electrical grid.
Without battery storage, you might not use this surplus directly, and its monetary value depends on feed-in tariffs offered by your utility.
3. Battery Storage System
A solar battery stores the surplus electricity generated by the solar panels instead of sending it to the grid.
This stored energy can be used later when the panels are not producing enough electricity, such as during the night or on cloudy days.
Energy Flow
Daytime (Surplus Production): Excess solar energy charges the battery after meeting the home's immediate needs.
Evening/Night (Demand Exceeds Production): Stored energy in the battery supplies the home when solar panels are inactive.
Grid Backup (Optional): If the battery depletes, electricity is drawn from the grid.
What are the components of a home battery storage system?
Battery Bank: Stores electricity in chemical form (e.g., lithium-ion batteries are common).
Battery Inverter (if required): Converts AC electricity back to DC for storage and then reconverts DC to AC for home use.
Charge Controller: Regulates the flow of electricity into and out of the battery to prevent overcharging or deep discharging.
What are the benefits of a home battery storage system with solar?
Energy Independence: Reduce reliance on the grid and save on electricity bills.
Backup Power: Provides electricity during power outages.
Maximized Solar Use: Store and use more of your solar energy instead of exporting it to the grid.
Cost Savings: Helps avoid high peak-rate electricity prices.
Can I add home battery storage to an existing solar panel system?
Yes, you can add domestic battery storage to an existing solar array, and it’s a great way to enhance the efficiency and usability of your solar energy system. Here's an overview of how to do it:
1. Assess Your Current Solar System
Inverter Type: Check if your current solar system uses a string inverter or microinverters.
System Size and Output: Ensure your solar system generates enough surplus energy to justify adding storage.
2. Choose a Compatible Battery System
AC-Coupled Systems: These connect to the AC side of your system (after the inverter). They are easier to retrofit and are compatible with most existing solar setups.
DC-Coupled Systems: These connect on the DC side (before the inverter). They are more efficient but may require replacing your current inverter with a hybrid model.
3. Install the Battery System
Hire a licensed solar installer or electrician to:
Install the battery and any required additional equipment, like a hybrid inverter or charge controller.
Integrate the battery into your home’s electrical system.
Update monitoring systems to include the battery.
