How Many Watts Do Home Appliances Use? Complete Florida Guide
Wattage, daily kWh and real monthly cost for 40 common household appliances — priced at Florida’s average 14.5¢/kWh rate. Sorted by what actually costs you the most.
The short version: the six loads at the top of this table — EV charging, air conditioning, heat pumps, hot tubs, water heating and pool pumps — account for the overwhelming majority of a typical Florida electric bill. Everything below them is rounding error by comparison.
Most people guess wrong about where their electricity goes. They worry about leaving a phone charger plugged in (26¢ a month) while a pool pump quietly burns $53 a month in the background. This table sorts every common household appliance by what it actually costs to run in Florida, so you can see where the money really is.
Every figure assumes Florida’s average residential rate of 14.5¢ per kWh and typical daily usage. Click any appliance for the full breakdown — including startup surge, amps, how many solar panels it takes to cover, and how long a home battery will run it during an outage.

What this tells you about cutting your bill
Three things jump out of the table.
First, wattage alone is meaningless. A toaster (1,200W) draws more than a refrigerator (350W), but the fridge costs 23 times more per month because it runs around the clock. Watts × hours is what matters, which is why the table sorts on monthly cost rather than nameplate rating.
Second, cooling dominates. Central air conditioning, heat pumps, mini splits, window units and dehumidifiers together make up the biggest single category on the list. In Florida that is not surprising, but it does mean efficiency work on your HVAC system and ductwork has more leverage than anything else you can do. Our airflow and duct sealing service routinely finds 20–30% of conditioned air leaking out before it reaches a living space.
Third, the top of the list is exactly what solar is good at. Air conditioning and pool pumps run hardest during daylight, which is when a rooftop system is producing. That overlap is why Florida solar tends to offset a larger share of the bill than the raw production numbers suggest.
Turning wattage into a system size
Florida averages about 5.5 peak-sun hours per day. After real-world losses, every kilowatt of installed solar produces roughly 4.4 kWh per day. So:
- Covering a pool pump (12 kWh/day) takes about 2.7 kW — roughly 7 panels.
- Covering central air (17.3 kWh/day) takes about 3.9 kW — roughly 9 panels.
- Covering a whole typical Florida home (~36 kWh/day) takes about 8 kW — roughly 19 panels.
Every one of our Florida city pages has a live savings calculator built on that city’s actual utility rate and sun hours, so you can run your own numbers in about ten seconds.
Sizing a battery instead
If your goal is hurricane resilience rather than bill reduction, the numbers you care about are different: continuous watts, startup surge, and total kWh. A 13.5 kWh battery holds about 12 kWh usable. Backing up the essentials — refrigerator, a few fans, lights, internet, phone charging, and a well pump if you have one — usually lands around 4–6 kWh per day, which is two to three days of runtime.
Add air conditioning and that drops to a handful of hours, which is why most critical-load panels leave central air off and use a mini split or fans instead. Our battery storage page covers how that panel gets designed.

Frequently asked questions
How many watts does the average home use?
A typical Florida home uses about 1,100 kWh per month, which averages out to roughly 1,500 watts of continuous draw. Peak demand on a hot afternoon with the air conditioner, pool pump and dryer running can easily exceed 8,000 watts.
What uses the most electricity in a Florida home?
Air conditioning is far and away the largest load, typically 40-50% of a Florida electric bill. Water heating and pool pumps usually take second and third place, followed by EV charging for households that have an electric vehicle.
How do I calculate what an appliance costs to run?
Multiply the appliance wattage by the hours you use it per day, divide by 1,000 to get kWh, then multiply by your electricity rate. At Florida average of 14.5 cents per kWh: a 1,500W space heater running 6 hours a day costs about 1,500 x 6 / 1000 x 0.145 = $1.31 per day.
How many watts of solar do I need for my whole house?
A Florida home using 1,100 kWh per month needs roughly 8-9 kW of solar to offset it fully, which is about 18-20 modern 440-watt panels. Your exact number depends on roof orientation, shading, and how much of your bill you want to offset.
How many watts can a home battery deliver?
Most residential batteries deliver 5,000 to 11,500 watts continuous with a higher short-term surge rating. That is enough to run a refrigerator, fans, lights, internet, and often a mini split or well pump at the same time during an outage.
