Battery storage systems, or battery backups, store excess energy generated by your solar panels for later use instead of sending it back to the grid. The larger the battery’s capacity, the more energy it can store.
When your solar panels produce more electricity than you need, the surplus energy charges the battery. Later, when your solar panels aren’t generating electricity, you can use the stored energy from the battery, day or night. Electricity is only sent back to the grid once the battery is fully charged, and you’ll only draw from the grid when the battery is depleted.

Reasons Why You Should Consider Battery Back-Up For Your Home
Self-Generation Incentive Program (SGIP)
This program provides cash rebates for installing energy storage technology at both residential and commercial properties
Solar Panel Stability
When the power goes out due to technical issues or weather conditions, solar panels with energy storage ensure your property always has a reliable power source
Investment Tax Credit (ITC)
As a taxpayer, you qualify for a 30% investment tax credit (ITC). However, note that a standalone battery is not considered renewable energy, as it can also be charged by grid electricity
EV Charging Impact
As a potential EV owner, it's important to consider that electric vehicles increase electricity demand during peak times when you plug them in to recharge
Factors to Consider When Choosing the Best Storage Option
Capacity refers to the total amount of electricity a solar battery can store, measured in kilowatt-hours (kWh). Power rating, measured in kilowatts (kW), indicates how much electricity the battery can supply at once.
A higher Depth of Discharge (DoD) allows you to use more of your battery’s capacity before recharging. This maximizes energy storage efficiency, providing more usable power and potentially reducing the frequency of recharging cycles.
Higher round-trip efficiency means less energy is lost during storage and retrieval, providing greater economic value from your battery. This improved efficiency lowers energy costs and maximizes your return on investment.
The typical lifespan of a solar battery is 10 to 15 years. Most solar batteries come with a warranty that covers a specified number of cycles or years of operation.
