Can a House Run on Solar Power Alone?
One of the most common questions we hear from homeowners who are thinking about going solar is whether solar panels can really power their entire home. The answer is a resounding yes. With a high-quality solar energy system that includes battery storage, you can absolutely run your whole house on solar power.
Boston Solar installs custom residential solar energy systems that are designed to match your home’s energy consumption so that your whole house can run on solar. Keep reading to learn more about what we consider when designing a whole-home solar energy system.
How to Run Your Whole House on Solar Energy
Size Position Your Solar Panels for Optimal Energy Production
Solar panels work by converting sunlight into electricity and distributing it throughout your home via your electrical panel. In order to power your entire home with solar energy, your PV system needs to be able to produce at least as much electricity as you consume.
To make this happen, you need to:
- Know how much electricity you use on a monthly basis
- Install enough solar panels to meet your electricity needs
- Make sure your panels receive adequate sunlight throughout the day
A custom solar panel system design will ensure that your PV panels are optimally sized and positioned to meet or exceed your home’s energy consumption.
When you go solar with Boston Solar, we’ll analyze the past 12 months of your electric bills to determine how many solar panels you need to run your house, while accounting for future expansions like an EV charger installation. We’ll also consider factors like daily sunlight hours, roof space, and more to design a custom solar system that can produce enough power to run your whole home.
Install Solar Battery Storage
Because solar panels use sunlight to generate electricity, they can’t power your home at night. To use solar power when there isn’t enough sunlight, you need solar battery storage, which allows you to store the excess electricity your PV panels generate during the day.
To run your entire house on solar power alone, you will need a large battery bank to keep your home running at night. If you maintain a grid connection, you’ll still be able to use the electric grid as a backup option should you run out of stored solar energy. If you decide to go fully off grid with solar panels in Massachusetts, you will need to make sure you have plenty of battery backup.
Switch to All-Electric Appliances
Many of the appliances we rely on, like furnaces, water heaters, and gas stoves, run on gas—not electricity. If you want to run your entire home on solar power, you’ll need to replace your gas appliances with all-electric appliances that can run entirely on solar power:
Electrifying your home allows you to cut fossil fuels out completely and run your home entirely on solar energy. By switching to all-electric appliances, you can save money on energy costs, reduce your carbon footprint, and even improve your home’s indoor air quality.

Can I run my whole house on solar power?
With the sun delivering an awe-inspiring amount of energy to the earth on an almost hourly basis, it stands to reason that solar energy can indeed power an entire house. Let’s take a deep dive into how exactly this happens and how you can make estimated solar calculations at home.
Owning a house that runs entirely on solar power is most definitely a possibility! With the help of solar panels and solar batteries, making your home a solar-powered property has never been cheaper. The cost of installing a solar energy system has dropped drastically in the past 20 years because of the fast improvements in technology. Even though it may be cheaper than ever, there are still a few necessities to make this dream of running your home on solar power alone, a reality.
First, you will need to understand how much energy you use on average per month.
This will allow you and your contractor to know how much energy your panels may need to generate to keep your home powered throughout the month. When considering the amount of energy generated by your panels, it is also Smart to understand that some months may be better than others for generating power. This is where solar batteries can play a crucial role.
When the sun doesn’t shine as bright or as long as usual, it is good to utilize your solar batteries. Solar batteries allow users to store excess energy gained on those long sunny days to be used later. This is key because if you have no energy stored, you will be required to use energy from the grid to power your home.
Secondly, the climate you reside in also plays a crucial role in making this dream a reality. If you live in a cold, cloudy place, it may be more challenging to run your home entirely on solar.
Third, the surrounding trees and houses located near your home. These can hinder the amount of energy that your solar panels can generate throughout the day. If you have a huge tree blocking your panels for a third of the day, this can drastically change the amount of energy stored.
Don’t let any of these three factors scare you away because running your home on solar alone has never been easier. With the help of solar estimators and countless numbers of installations in your general area, solar contractors understand the ins and outs of what may be needed to allow you to make this leap to solar energy.
The key to this possibility is the number of panels and solar batteries installed on your home. The critical part is the use of solar batteries; without a battery, no excess energy can be stored to use later.
For many homeowners, 100% coverage using solar energy is a reasonable goal. As long as your property is suitable for the size solar system you need, you should be able to completely offset your energy usage with solar.
If you want to power your home with only solar panels, you need to plan it through. Do a power audit for your home to determine your consumption. Once you have an idea of your usage, find the best solar power system, and invest in a solar battery. Looking for an expert solar installation for your home? Let Aztek Solar do it for you.

How Many Solar Panels Are Needed to Run a House? (The Answer Will Surprise You!)
Are you thinking about adding solar to your home? With over 2 million homes in the United States with solar now, many homeowners are recognizing how beneficial they are. If you’re considering having solar panels installed in your home and not sure where to start, then you’ve come to the right place.
We’re going to go over the details of how solar panels work and how many you might need for your home.
How Do Solar Panels Work?
Simply put, solar panels absorb photons that then tap electrons free. Once they’re free from the atoms, it creates electricity! Solar panels take in light and directly turns it into a flow of electricity to use.
- Solar panel cells absorb sunlight
- They convert the light into DC power.
- All systems need some type of inverter (string, Micro or hybrid) to convert that power to AC power.
- The electricity is then sent through wires into your home
- That powers everything connected to it
- Any excess of electricity produced is then fed into the electric grid
Solar systems are not complicated and easy to understand once you have the basics down. Now that you understand how they work, let’s take a look at how long they last –
How Long Do Solar Panels Last?
In short, a quality solar panel can last up to 25 years or even longer. Solar panels are designed to live a long life in the elements outside.
Your typical solar panels come with a warranty that lasts 25 years, so you are guaranteed to reap the benefits for quite a long time.
According to a study conducted by the National Renewable Energy Laboratory, solar panels last 80% longer than their warranty.
This can save you thousands on utility bills down the road!
How many Solar Panels Do You Need?
To find out how many solar panels you’ll need for your home, you need to consider everything that uses power. Taking a look at your utility bill can also give you a good idea of how many you might need.
How Many Watts Do You Use?
When looking at your utility bill, you should be able to see kilowatt-hours (KWH). KWH for homes can vary greatly depending on location. A home in the south is more likely to draw massive amounts of energy from air conditioner units.
Finding the average daily energy usage will help you calculate your solar needs. Once you have your usage you can look at how much wattage you’ll need to be able to run everything.
Peak Sunlight Hours
Keep in mind that solar panels only work when they are in direct sunlight. After the sun is no longer shining down on them, they aren’t producing energy. Peak sunlight hours are when your panels are in direct sunlight.
Depending on your location, your peak sunlight hours can vary.
Multiply your home’s hourly energy usage by the peak sunlight hours your home has and then divide that by a solar panel’s wattage. You can do this both high and low wattage panels to find a range of what you might need.
Most reputable solar companies can also help you determine this by providing them with this basic information as well!
Solar Panels For a 1500 Square Foot House
The average home in the United States is roughly 1500 square feet. With a home of this size, the typical electric bill comes in around 100 month. In order to cover the electricity for this home, you would need an estimated 15-18 solar panels.
For example, a typical fridge may be rated for 250 watts and runs for 4 hours a day. 250 watts X 4 = 1000W. A 1k watt is equal to 1 kWh of energy in a day.
This, of course, is a general estimate and eclectic usage, sunlight hours, location, and the type of panels can change this amount.
Types of Solar Panel Systems
When it comes to solar panel systems, there are three different types. Gid-tied, grid-tied with battery backup, and off-grid. Let’s take a look at each one.
The most popular type of system used by residential houses is the grid-tied system. This type of system is tired directly to your home and the utility grid. This allows homeowners to seamless switch between power from either the solar system or the utility system.
If the system produces more power then the house needs, the excess power will be sold back to the utility company or it will be used to prorate your bill.
These are generally the cheaper systems out of the three.
Grid-Tied With Battery Backup
Similar to the grid-tied system, this solar power system is also connected to both your house and the utility grid. However, it also comes equipped with a battery bank.
When the panels produce electricity while in direct sun, it stores any excess power in its battery banks. This power can then be used at a later time after the sun has gone down and the panels are no longer producing power.
The power can also be sold back to the utility companies as well – This system is much more expensive though because of the expensive price of batteries.
Unlike the other two, the off-grid system is not connected to the utility grid at all. This system is only connected to your home and a battery bank. The battery bank is essential in this setup in order to continue producing power for your home 24 hours a day.
This tends to be the most expensive system because you need an excessive amount of battery in order to store the amount of energy your house will need.
How Much Do Solar Panels Cost?
Solar energy has become cost-effective most recently. The have gone down and they are much more available to the public. The average cost of a solar panel is almost less then half it was a decade ago.
A typical solar panel can run between 50 cents to 70 cents per watt. At 50 cents a watt, a 350W panel would cost 175. In a typical home needing 15 solar panels, the total cost for panels would be 2,625.
That is for the panels alone though, the cost of installation needs to be considered as well. It takes professional that know what they are doing to properly install a solar system in your home.
How Much Does a Solar Installation Cost?
This can vary depending on the company, but for an average installation, it can run you between 15,000 and 30,000.
Many solar companies offer incentives and financing. There are a ton of other financial benefits that come along with installing your home:
- Electricity rates have risen across the nation and are higher now than they have ever been
- You can save thousands on electricity bills and will only continue to save more over time
- The resale value of your home skyrockets. Many home buyers now are searching for homes that come with a solar system already installed
- The government offers a massive tax credit when it comes to solar systems. Some states also offer a rebate program
- The systems come with a warranty that secures your investment for at least 25 years
How Much Does it Cost Total For a 1500 Square Foot House?
The typical 1500 square foot house can use around a 6kw solar panel system. The total cost of the panels and full installation can be estimated at about 18000.
To get an estimate for your home and how much you can save, contact a local energy consultant. They can provide you with an installation quote and answer any questions you have about solar systems for your home.
Things to Keep In Mind

How Many Solar Panels Do You Need to Run a House Off the Grid?
Going off-grid with solar in Arizona is more complicated than installing a grid-tied home solar energy system. You’ll need more solar panels than a grid-tied system as well as plenty of backup power. While we can’t pinpoint exactly how many solar panels and batteries you’ll need to go off grid without discussing your specific energy needs and location, we can give you a better idea of what it takes to run an Arizona off-grid solar home.
According to the EIA, American utility users consume an average of 893 kWh of electricity per month. That’s about 29.33 kWh per day. Most residential solar panels can produce between 250 and 400 watts per hour, depending on their size.
For simplicity’s sake, let’s say you decide to install 300-watt solar panels and your solar panels receive 6 hours of sunlight per day. You’ll be generating 1.8 kWh per panel per day. To meet the average requirement of 29.33 kWh of electricity per day for your household, then, you’ll need 17 solar panels.
Of course, this is just one example. To find out how many solar panels it would take to power your off-grid system, schedule a consultation with SouthFace Solar Electric.
Backup Batteries Generators for Off-Grid Solar
Because they are not connected to the electric grid, off-grid solar systems must meet the home’s electricity needs completely. This means they need to have backup power for use at night, on overcast days, and to maintain power if the solar panels malfunction or become damaged.
It’s best to have multiple sources of backup power for your off-grid home. A combination of solar batteries and generators will give you plenty of reliable backup power and the peace of mind that comes with it.
How much backup power you need for off-grid solar depends heavily on the amount of power you use and the amount of electricity your solar panels generate. SouthFace Solar Electric can help you make the right solar battery and generator choice for your home.
