How to Run Your House Solely on Solar Power  | Starter Guide

Around the world, solar electricity has been able to sustain entire towns on its own. That being said, you can certainly run your house solely on solar power. 

With the ability to power everything from pocket calculators to large cities, it is the most versatile power source the world has ever seen.

And it’s clear that a single house can be powered by solar when you take into account that enough sunshine strikes the Earth every hour to power everyone on the planet for a complete year. 

Why wouldn’t anybody want to turn their ancestral homestead into a solar-powered machine? It seems like the recipe for success, doesn’t it? Going solar can have a number of very significant advantages. 

However, exercise caution: Before you sever the connection with your local utility supplier, there are many things to consider.

After the initial cost of system setup and ongoing maintenance, solar electricity is free. 

Solar energy is efficient, yet various experts disagree on how efficient it is. Not to mention that solar energy produces no pollution, which is important to many of us in this day of climate change.

The more important question, however, is “how to run your house solely on solar power”. We have compiled everything you need to know in this article. 

What is the Solar Panel System Size?

Appropriate system size is the first, and most likely, most significant, need for using solar power to power your entire home.

Your home won’t have enough power if you have fewer panels than what’s needed, and you’ll spend more money if you have more panels than what’s needed.

So, a system design is used to determine the system size. Your system design determines how many solar panels you will require based on your past energy consumption.

Therefore, to get a ballpark idea of how many solar panels you could require, utilize a solar calculator. This will also help you estimate the possible savings that your system might produce.

Can I Run My Whole House on Solar Energy?

You can certainly run an entire house entirely on solar energy with a sophisticated solar energy system that includes power storage.

The cost of powering a whole house entirely with solar energy has never been lower thanks to today’s highly efficient solar panels and solar batteries.

Since the general introduction of solar energy use for home and commercial purposes twenty years ago, the costs of solar panel systems and installation have continued to decline.

So, this is true even when utility company incentives, state and local government tax breaks and rebates, and federal tax credits are decreasing year.

The significant decline in solar costs can be attributed in part to the growing use of solar energy on a national and international level as well as to the quick development of solar energy system technology.

Furthermore, start with these initial fundamental assessments to ascertain the viability and cost-effectiveness of running a totally solar-powered house:

Calculate how much electricity you use per month.

To power your entire home with solar energy, first calculate how much solar energy you will need to create. You’ll need to know your typical monthly electricity consumption in order to do that.

Also, your solar contractor will be able to determine how much electricity your panels must produce each month to power your entire house thanks to this.

Naturally, variations in monthly usage and solar power generation potential are to be expected throughout the year.

Modern household solar battery storage systems have reserve capacity that can help you guarantee a consistent power supply for your house.

The extra power your solar panels generate on longer, sunnier days can be stored in your solar batteries for use whenever you need it during less sunny times.

Solar batteries make sure you have all the power you need to run your complete house during times when there isn’t as much direct, bright sunlight. Without them, the system will automatically start drawing electricity from the public grid.

Evaluate your climate region’s solar energy production capacity.

How much solar energy you may anticipate to generate to power your entire house year-round depends entirely on the environment where you reside. 

Assess whether the environment in your area can support the production of solar energy sufficient to power your entire home on a continual basis.

It might be more difficult for homeowners to run a house completely on solar power throughout the winter for those who live in colder, cloudier climates, such those near the northwest Pacific coast. 

People who live in southern states might not experience a cloudy day for weeks, while residents might not see direct sunlight for weeks at a time.

These climate variations, in addition to elements unique to your house and way of life, can mean the difference between being able to run your entire household completely off the public power grid and still need at least some electricity from your utility provider.

Assess your solar production environment based on your home’s surroundings.

Take into account the height of the surrounding homes and other structures, as well as the quantity and vicinity of huge trees that are growing around and near your property.

Large trees and tall buildings that are close enough to your house to shade your roof heavily for more than a third of the day can significantly lower the efficiency of your solar energy system.

What are the Factors that Impact The Ability to Reach 100% Coverage with Solar Energy?

How Much Energy You Use

In order to completely satisfy your house’s energy requirements, your solar installation must first ascertain the average amount of energy consumed by your house.

Examining your historical electricity usage—which is included in your electricity bills—is the most popular method.

It will go beyond simply reading the most recent bill, though. When creating a system that satisfies all of your energy requirements, a solar installation must consider a great deal of elements.

You’ll probably use different amounts of electricity in different months and during different seasons.

Spring and fall milder temperatures could result in cheaper electricity costs than summer’s scorching heat and running air conditioners nonstop. Wintertime electricity usage may increase due to longer days and more time spent inside.

Therefore, for a complete understanding of the size of the system you will require, your solar installer must average out how much electricity you use on a regular basis.

The local climate and weather are additional variables to consider. A solar system in Florida will generate less electricity annually than one in Washington, even though solar energy has shown to be viable in even the most overcast or rainy of conditions.

Your system will produce a lot more electricity in the summer than it will in the winter, no matter where you reside.

Also, installers will use local average weather patterns to determine an accurate estimate of the amount of electricity you can reasonably produce year-round.

Your Available Space

Installing solar panels in a bright, sunny location that won’t obstruct your daily activities is necessary.

The roof is often the most sensible location for solar panels on a property, but if ground-mounted solar systems are more appropriate for your needs, solar panels can also be erected on land.

Roof-Mounted You’ll need the area necessary to install a solar system that can supply all of the electricity needed for your home. A 330W solar panel occupies around 19.5 square feet. 

A normal home’s solar system capacity will be between 5 and 20 kW. Therefore, to build a system that will suit your needs, you’ll need between 312 and 1,189 square feet of sunny space with few obstacles.

Roofs are not made equally. Roofs that face northward receive less sunlight throughout the day, so you might need to install more panels to make up for the production loss. 

It could be necessary to prune or remove any trees that provide shade to your roof throughout the day. Additional hindrances such as adjacent structures, chimneys, and exhaust fans may further affect output.

The ability to tilt and position a ground-mounted system to maximize solar production is one of its key advantages. A roof mount might not be able to accomplish this.

Deciding Between Off-Grid vs Grid-Tied

You can use an off-grid or grid-tied solar system to power your home entirely with solar energy if that is your objective. What happens to your extra electricity and how you get electricity when your system isn’t producing power are the differences between these two.

You will still need to use your system even though it won’t produce as much electricity on cloudy or wet days or at night. So, by producing more electricity during the sunny hours, solar power may still give you electricity during these times.

Furthermore, if you choose a grid-tied system, the extra electricity is either transmitted to the electrical grid in exchange for a credit, or it is stored in batteries in the case of off-grid systems.

A solar system that is fully independent of the electric utility is known as an off-grid system. This implies that the utility won’t be able to supply power to your house.

Going off the grid, meanwhile, can be costly and call for certain adjustments to one’s way of life. 

Even though battery prices are still dropping, it can add up to buy enough to last you through a few cloudy days and dark nights. You will need to be aware of the difference between the amount of electricity your system can store and the amount you use.

You won’t need to buy batteries to store surplus energy if your system is grid-tied, allowing you to produce all the electricity your house needs.

FAQs – Run Your House Solely on Solar Power

Is a house able to function only on solar power?

A house can be powered exclusively by solar energy. Going totally off the grid, however, necessitates a significant time and money commitment. You’ll need more solar panels the more electricity you consume.

What drawbacks are there to solar energy?

Weather dependence is the biggest disadvantage of solar energy since cloudy, gloomy, and wet weather prevents the panels from gathering energy. The high upfront cost is another significant drawback, particularly if you’re going fully off the grid.
Although solar energy is the least priced renewable energy source, it is still four times more expensive than conventional energy sources.

What is the price of solar panels for a 1000 square foot home?

Calculating your solar panel requirements based on the location and monthly cost of your electricity bill is simpler. 
According to general criteria, a 1,000 square foot home with an average monthly power expenditure of $50–60 should have at least a 5-kilowatt system installed by the homeowners. A 5,000-watt solar power system will set you back about $15,000.
This is because the average cost per watt in the United States is $3. This ignores crucial elements like your unique location (and weather), the orientation of your roof, the kind of home you own, and the state and federal funding that are available.

Why is solar power important?

Investing in solar power is important because it can reduce or eliminate the need for fossil fuels to produce electricity and power our homes.


Solar energy is an amazing source of power. The sun is the source of energy for everything on Earth, including a single house. All you have to do is make sure your system is installed and sized correctly to accomplish that.

In the past, homes could not have been successfully and efficiently powered through the evenings or darker days due to the intermittent nature of solar electricity. 

Customers may now select from a variety of backup systems that guarantee that a portion of the house or the entire structure can function solely on solar power thanks to advancements in smart technologies and sophisticated batteries. 

In the end, it’s up to you how and to what extent you want to rely on solar and grid power to power your appliances.
