If you’re tired of hearing all those easy-to-say but hard-to-prove statements like “Save money with solar power for home energy!” that don’t have any hard numbers to back them up, you’ve come to the right place. Show
How much energy do the various energy systems in your home actually use? How much can solar power offset them? Now’s your chance to dive into some real numbers. So, let’s get to it! Disclaimer: This Is the Internet, Not Stone Tablets The following information has to make a number of assumptions. It’s impossible to avoid, because every appliance and home energy system is different. They have different efficiencies to begin with, but also different ages, different quality, and all the rest. So don’t take this as truth from on high and then get upset if your numbers turn out a bit different. But what you’re about to see are real numbers. Most come from various pages on Mr. Electricity’s website, an extremely well-researched and well-respected website for all things electricity. We’re also assuming you have a solar power home energy system that produces 50 kWh per day. Our example does not include a solar power battery system. This too varies depending on the size of the solar array you’ve installed on your home, where you live, the weather, and many other factors. But since most homes are comparable enough in size and we can’t control the weather, 50 kWh per day is a good number to use, though maybe a bit on the high end for some homes. So: What Can You Power in Your Home’s Energy System With 50 kWh of Solar?With 50 kWh of solar piping into your home each day, you could run your desktop computer all day for 13 days. You could run a 2.5-ton central AC system for 14.3 hours (yes, AC is an energy hog). So, assuming you aren’t running air conditioning all day long, solar can power your home’s AC energy needs. 50 kWh per day of solar power also allows you to bake at 350oF in your electric oven for 25 hours, though that might overcook your ham just a bit. A typical 50 gallon electric water heater uses 385 kWh per month, which is about 12.8 per day, well under the 50 kWh produced daily by your hypothetical home solar energy system. And now, for the number you’ve all been waiting for: You could run 26 loads of laundry on the warm/cold setting in a top loading washing machine. Use hot water, and it’s a lot less. Use cold/cold, and you can do even more. Remember – these are all based on a solar energy production rate of 50 kWh per day, which is 1500 per month. We can keep going. But to make it fun, and a little more true to life, here are three scenarios that show what 50kWh per day of solar power makes possible for your home energy needs. Power Your Home’s Energy with Solar: 3 ScenariosHere’s what you can do with 50 kWh of solar power in one day. Scenario 1: Sitting on the computer all day in May instead of being outside like you should be
Scenario 2: Big family laundry day in the hot summer
Scenario 3: March Madness – Day 1. 16 games on the 65 inch plasma
Of course, your home uses electricity for many other things besides these, but you can see here that a good-sized solar power system can supply many of your home’s energy needs. Most systems that provide solar energy for homes don’t completely offset your power bill, and that’s not usually the goal. A good target goal is to offset 70% of your average monthly power needs. Some months it will be more, others less. But now you have some examples of what you can do with solar power. Home energy systems that use consistent amounts of power, like refrigerators and hot water heaters, are the easiest to make predictions about. Figure out your actual numbers, and then see how much solar power you’d need to offset them. How many kW of energy does a house use per day?That means that the average kW used in U.S. households is 30kW per day, which averages at around 900kW per month. As a disclaimer, these figures are calculated from the U.S. home average of kilowatt-hours per day.
How many kilowatts of electricity does it take to run a house?In 2021, the average annual electricity consumption for a U.S. residential utility customer was 10,632 kilowatthours (kWh), an average of about 886 kWh per month.
How many kilowatts a day does a house use UK?What is the average electricity usage per day in the UK? The average UK household will use between 8.5kWh and 10 kWh of energy. This is only a guideline figure as there are many influencing factors that affect this figure.
How many watts does a normal house use per day?How many watts does an average home use? According to the Energy Information Agency (EIA), the average American home uses an average of 10,715 kilowatt-hours (kWh) of electricity per year. That's 29,360 watts (W) per day, which can be divided by 24 hours to get an average of 1,223 W to power a home throughout the day.
