How Many Solar Panels Do You Need to Power Your Home?

It’s 2021, and almost everyone is switching over to green energy rather than using direct electricity. If you want to make use of this, having solar panels in your home or commercial place could bring in a massive change.

Don’t worry much about the costs because solar panel installation is a one-time investment, and it could save you money for years. Of course, with an advanced solar panel system and equipment, you’ll be able to switch on multiple electrical units in your home and end up saving your money.

But if you’re confused about how many solar panels your install, this guide should is exactly for you. Without any further delay, let’ get started to work on this.

How to calculate your own solar panel estimate?

Using solar panels is always a big thing, but if you wish to use one of them, it is always important to know about the costs and estimations of using one. Here is a quick guide on solar panel cost and an estimation of your solar panel purchase.

Of course, every home has different requirements for solar panel installation. Some of them happen to provide you with decent productivity, while some of them might provide lower. The first thing you need to do is get a clear estimation of the number of electrical units running your home.

Any average home all over the USA consumes around 867 kWh, which will help you to get. To make it around 1000 kWh of power, your home must have at least 20 bulbs running with every 50 Watts. The average consumption of electricity requirements in a home is around 11000 kWh. This will also mean that you will require multiple solar power panels.

The solar panel estimate completely depends on the power requirements you have and the specifications you require. A panel production ratio of 1.61 is resembled to be good enough.

How many solar panels do I need for 1000 kWh per month?

If you look closely, a 1000 kWh power requirements in your home means that you have a large family. If you do not have a large family, you’re looking for requirements about a commercial place. So let’s get down straight to calculations.

The number of solar panels you need to include will completely depend on the electricity requirements. Let’s consider you consume around 1000 kWh, which means that it will be around $200 of electricity charges. To get accurate measurements, you will have to first think about the number of appliances being used and the average daily consumption. If you want to get a clear idea, a total of 1000 kWh in a month earns that your solar panels will have to generate around 33.33 kWh per day.

Let’s now view the average daily production rate for any single solar panel that might provide you around 5 to 6 kilowatts. This will be calculated if the panel receives around 6 peak hours of sunlight.

No energy conversion system sits perfectly. There might always be a deflection of 20% when providing a higher level of electricity. So let us calculate the number of panels that you will need.

Every solar panel produces a range of 5 kW in a charging time of 6 hours. So you can expect that every solar panel will at least have a capacity of 8 kW in a full day. Please take out a 20% deflection, and it cuts down to 7 kW.

Now the total number of solar panels you need is roughly around 5 to deliver you a total power capacity of 35 kW. In a month, this will accumulate to a total of 1050 kWh. Simultaneously, if your solar panel productivity is much lower, you will need more panels. For 250 watt panels, you will need at least 30, while for 500 Watt panels, you will need at least 15.

What is the exact Solar Panel power Requirement?

The commercial solar cells available today probably speak to state of the art for quite a long time to come. Great solar panels made out of monocrystalline silicon cells generate about 100 milliwatts per square inch (6.45 square cm). Commercial panels arrive in various sizes, 100 watts and up; be that as it may, the power generated per square inch remains about 100 milliwatts. The number of panels required can decrease, however, not the area.

Average Home

How much electricity does an average 2-story 3-room house use per day, per month, or year? The US Energy Information Agency has estimated that the average U.S. home uses 8,900 kWh (kilowatt-hours) per year or about 24 kWh per day. If this average home is in a climate that will create an average of 6 hours of daylight for maximum power generation, each square inch of optimally situated panels can deliver 600 milliwatts per day.

Thus, about 40,000 square inches (24000 watts per day/0.6 watt-hours per inch) or 278 square feet of solar paneling would address the family unit issue. If purchasing a 100-watt panel measuring about 6 square feet, an average home would require 46 panels.

Your Home

These calculations are for a fictional system; however, they fill in as a rule. Your energy necessities may be substantially more or less than the average value utilized above. If your goal is to diminish your electricity bill to zero, you basically need to know your home’s normal requirements to advise you if it is conceivable and practical.

Electrical company solicitations regularly show flow months usage, yet earlier months as well. On solicitation, the company may have the option to give a year total. Alternatively, one can take meter readings each day longer than a week or even a month to incorporate a couple of ends of the week when power use is typically higher.

Since usage typically is seasonable, this ought to be taken into account. For the greater part of the U.S., winter usually speaks to the most noteworthy period of usage; however, in certain areas of the nation, summers requiring maximum utilization of AC may speak to peak usage.

For example, if your energy bills or meter readings show that your yearly usage is 12000 kWh per year, a solar power system would require a 63-panel array (47 x 12000/8900 = 63) of 100-watt panels. The rooftop space required would be 375 square feet.


Switching over to the use of solar panels could make this world and your environment a happy place. I’m sure you would never want to miss out on this. To make it more comfortable to use, always do calculate the number of solar panels. Overloading on the number of electrical units will always be dangerous. Having an adequate number of solar panels is the only way to go forward. Do let us know if you have any problems while installing solar panels.
