Deciding to install solar panels in your home means one thing – eliminating the electricity bill forever. Honestly, we understand, but it is not that easy. When determining the number of solar panels needed to power your home, there are many factors involved.
To calculate the number of solar panels, it will take to power your home depends on the following factors.
- The size and location of the house
- Your electricity usage and habits
- The number of people in the house
- The type of solar panels
- Installation position
How many solar panels will power a house?
Before you decide on the number of solar panels that your house needs, you have to determine the energy consumption for the house. This is crucial as different solar panels produce a definitive amount of energy for the home.
Furthermore, you need to know exactly how many people live in the house, what their electricity habit is, and appliances that will use the power generated. Adding to the above is the location of the house – areas with more sun will enjoy more power than regions without.
Over the years, the electricity consumption per household in the United States has increased tremendously in the last decade; this is due to houses and commercial establishment having more appliances that need the power to function. Read up on how many solar panels run an air-conditioner in a home.
The average American house consumes about 10, 972 KWh every year, which is about 914 kWh per month. This is for a regular house, add the computers and other large appliances, you are almost at 1000kWh per month.
So if your house consumes 1000kWh per month, in a day, we will have 1000/30 day = 34kWh per day.
Will the amount of sunlight affect the number of solar panels?
Now that you know the average monthly and daily consumption for a house that uses 1000kWh, the number of sunlight will also influence the number of panels. Areas like California, Arizona, and Nevada get up to 9 hours of hot sunlight in a day.
Now divide the consumption per day by the hours of sunlight, in this case
34 / 9 = approx. 4 kWh
Solar panels come in watts, so to know how we have 4000 watts in 4 kWh.
4 * 1000 = 4000 watts
That means for a house that uses 1000 kWh per month with 9 hours of sunlight will need solar panels that can produce 4000 watts of energy daily to power the house.
Now this average will be different and panels more if you reside in states like Arkansas and Washington with less than 5 hours of sunlight in a day.
Using the breakdown, you will need almost 6000watts daily to power your house.
What are the right solar panels to power a home?
For residential use, the photovoltaic solar panels are the most used. They are reliable because they absorb every drop of sunray and use cell technology to quickly convert sunlight into energy. This means no wastage and longer hours with power even in dark nights.
These panels are available in different wattages from 150 to 370 watts per panel. Now the math continues.
If you opt for a PV solar panel of 250 watts, for example, this means you will need
4000/250 = 16 solar panels for a place that gets 9 hours of sunlight.
For areas like WA with 5 hours of sunlight, 6000/ 250 = 24 solar panels
Now when you contract a solar panel service to install the panels, you will get more than the number of panels stated here.
Let’s explain because the electricity in your house will fluctuate or you might buy more appliances in the future, a good technician will install 16 to 20 panels to cover for the lags. These extra panels will also save you a lot on days when the panels do not get up to 9 hours of sunlight.
Is there a better option for your house?
Now, there is a kicker to solar panels. If you do not have the space to mount such huge rectangular panels that is problem number one. Secondly, they are too expensive and powering a home that consumes 1000Kwh of electricity means up to 20 – 30 solar panels that will cover your entire yard space. If you decide on a rooftop installation, you will have to ensure that the structural integrity of the building can sustain the weight over time.
All these hiccups just to cut electricity bills or have uninterrupted power
Is it even worth it?
Yes, solar panels are worth the hassle, but you have to make proper research into innovative brands. They will provide power, save you money, and make a decent utilization of ground space.
