Keep Your Power On With Solar Battery Storage
A solar battery stores the extra power your panels make during the day. You use that stored power at night or during an outage. In Orlando, where summer storms knock out power every year, a battery turns your solar system into a backup plan.

How Solar Batteries Work
During the day, your panels often make more power than your home uses. Without a battery, that extra power goes to the grid for net metering credit. With a battery, the extra power charges the battery first.
At night, your home pulls from the battery instead of the grid. If the grid goes down, the battery and panels power your home on their own. When the battery runs low and the sun is up, the panels recharge it.
Most home batteries today use lithium iron phosphate chemistry. They are safe, long-lasting, and need no maintenance. Popular sizes store between 10 and 15 kilowatt-hours each. Bigger homes often use two or more.
Whole-Home vs Critical-Loads Backup: An Honest Look
This is the most important choice in battery design. Here is the honest breakdown.
Critical-Loads Backup
A critical-loads setup backs up only the circuits that matter most. Fridge, some lights, internet router, a few outlets, maybe a bedroom fan. This costs less because the battery and inverter are smaller. It covers the essentials for hours or even a day.
Most Orlando homeowners pick this option. It keeps food cold and phones charged through a typical outage.
Whole-Home Backup
A whole-home setup backs up every circuit, including the air conditioner. This needs a much bigger battery bank and a larger inverter. It costs a lot more. A central AC unit pulls a huge surge of power when it starts.
Be honest about expectations. Running full AC through a multi-day outage takes a very large system. Many homeowners find a smaller backup plus a portable plan works better for the budget.
The Middle Path
Some homes back up critical loads plus one mini-split AC for a single cool room. This is a smart compromise in Florida heat. You get real comfort without the cost of whole-home backup.
Who Is Battery Storage For?
Battery storage fits homeowners who already have solar or are getting solar now. It also fits anyone who loses power often. Orlando gets strong summer storms, tropical systems, and the odd hurricane. If outages stress you out, a battery brings peace of mind.
It also fits homes on time-of-use thinking. You store cheap daytime solar and use it during expensive evening hours. Florida net metering is already 1-to-1, so the money math is softer than in some states. The main value here is backup and control.
What Affects the Cost
Battery Size
More storage costs more. A single 10 to 13 kilowatt-hour battery is the common starting point. Stacking two or three doubles or triples the storage and the price.
Backup Scope
Critical-loads panels and wiring cost less. Whole-home backup needs bigger inverters, more batteries, and often an electrical panel upgrade.
New vs Retrofit
Adding a battery at the same time as new solar is cheaper. The crew is already there and the inverter can be sized for both. Adding a battery to an existing system later is still very doable but takes a separate install visit.
Inverter Type
Some batteries pair with your existing solar inverter. Others need a hybrid inverter that manages panels, battery, and grid together. Hybrid inverters cost more but give the cleanest backup switch.
A Note on Incentives
The 30 percent federal residential credit under Section 25D ended December 31, 2025. Standalone batteries installed in 2026 do not get it. Florida sales tax exemption applies to solar equipment, which helps on the battery and related gear.
Florida-Specific Notes
Heat is the enemy of batteries. A garage in Orlando can top 100 degrees in August. Batteries last longer in a cool, shaded spot like a laundry room wall or a covered patio area. Good installers plan placement around Florida heat.
Florida building code requires proper clearances, ventilation, and disconnects for battery systems. Local fire code rules apply too. Permits and inspections are part of every install.
During hurricane season, a charged battery is real security. Charge it full when a storm is forecast. After the storm, panels recharge it each sunny day even if the grid stays down.
Frequently Asked Questions
How long will a battery power my home in an outage?
It depends on the battery size and what you run. A single 13 kilowatt-hour battery running a fridge, lights, and phones can last a full day or more. Add an AC unit and it may last only a few hours. Your installer should model this for your home.
Can I add a battery to my existing solar system?
Usually yes. AC-coupled batteries work with most existing systems without changing your panels or inverter. The install takes a day or two.
Do batteries need maintenance?
No. Modern lithium batteries are sealed and maintenance-free. The monitoring app shows charge level and health. Most carry a 10-year manufacturer warranty.
Will a battery lower my electric bill?
A little. You use more of your own solar instead of buying grid power at night. But Florida already has 1-to-1 net metering, so the bill savings are modest. Buy a battery mainly for backup, not for bill math.
What happens when the battery is full and the sun is still shining?
The extra power flows to the grid for net metering credit, just like a system with no battery. Nothing is wasted.
Is it safe to have a big battery in my home?
Yes, when installed to code. Lithium iron phosphate batteries are very stable. The install includes disconnects, proper wiring, and clearances that meet Florida fire and electrical codes.
