How Many Solar Panels Do I Need in Chicago?
Homes in Chicago, Illinois, are well-suited for solar energy use. On the real estate website Zillow, many of them have a SunNumber rating above 90. Redfin has recognized Chicago as the second-best city in the Midwest for solar energy potential.
According to the U.S. Energy Information Administration, the average American home consumes about 886 kWh of electricity per month. This means that the average monthly electricity bill is approximately $135.

Understanding Solar in Chicago
Solar panels in Chicago convert sunlight into electricity through a phenomenon known as the photovoltaic effect. This process is based on the interaction of sunlight with semiconductor materials in solar cells, leading to the generation of electrical power.
As inflation continues to erode the value of the dollar, harnessing solar energy and converting it into electricity is becoming increasingly important. Installing solar panels in Chicago can improve your family’s financial situation and help you contribute to a more sustainable future in a safe environment.
The Efficiency of Solar Panels in Chicago and Cost Considerations
The presence of solar panels does not automatically mean that your home is off the grid. An off-grid solar system is a self-contained energy system that generates and stores electricity independently.
Such systems use Chicago solar panels to generate electricity, which is then stored in batteries. When you need power for your appliances, an inverter converts the stored energy from the batteries into alternating current for use.
In grid-tied systems, the electricity is not only used by the homeowner. They are connected to the centralized grid and can send excess energy generated by the solar panels back to the grid. This often results in receiving credits on your energy bill through net metering.
The main advantage of these systems is higher efficiency relative to cost, as you do not need additional expenses for expensive energy storage batteries.
How Many Solar Panels Do I Need for My House?
The number of solar panels needed depends on many factors and can vary significantly from one household to another. Here are some key factors that affect the number of panels required:
- Power rating of each panel
- Efficiency of the panels
- Amount of energy the solar panels can generate
- Energy consumption of your household
- Size of the panels
- Number of peak sunlight hours you receive
- Condition and shading of your roof
- Your personal energy needs and goals.
How do I calculate how many solar panels I need? Here is a formula to help you determine how many Chicago solar panels you will need: Desired energy output (kW) / Power of one solar panel (kW) = Number of required solar panels.
To use this formula, you first need to know:
- Your home’s monthly energy consumption
- The power rating of the solar panels you choose
- The daily number of peak sunlight hours your home receives
Before proceeding with solar panel installation in Chicago, consider taking the following steps:
- Review your monthly electricity bill to determine how many kilowatt-hours of electricity you consume each month. Annual electricity consumption provides a more accurate estimate. How many solar panels do you need? Bills from the past 12 months can help you understand this better. Energy consumption varies throughout the year (e.g., using air conditioning in the summer), so your last bill may not reflect your peak consumption. For example, let’s use 1500 kWh per month as an average.
- Convert monthly energy consumption to daily by dividing by the average number of days in a month, which is approximately 30.42 days (365 days per year divided by 12 months). So, average daily consumption = 1500 kWh / 30.42 ≈ 49.3 kWh per day.
- Determine peak sunlight hours. Assume your home receives an average of 5 peak sunlight hours per day. To calculate total daily energy production, divide daily energy consumption by the number of peak sunlight hours. This gives the amount of energy your solar panels need to produce daily. Required energy production = 49.3 kWh per day / 5 hours ≈ 9.86 kW.
- Calculate the number of panels needed, considering the power rating of the solar panels you plan to install. The average power rating of solar panels in the U.S. ranges from 250 to 400 watts. For this example, use a power rating of 350 watts. Convert the panel’s power to kilowatts: 350 watts = 0.35 kW. Divide the required daily energy production by the output of one solar panel. Number of required solar panels = 9.86 kW / 0.35 kW per panel ≈ 28.17 panels.
Thus, this hypothetical homeowner would need approximately 29 solar panels to generate enough electricity to cover their current consumption. Note that this calculation is simplified. Many factors can affect solar panel efficiency, such as shading, roof orientation, and seasonal variations in sunlight intensity. For more information, you can consult solar panel companies in Chicago.
How many solar panels do I need to power my house? To understand this, it is advisable to consult with professional solar installers in Chicago, who can assess your conditions and offer a customized solution tailored to your needs. They should be certified by the North American Board of Certified Energy Practitioners, which is a standard in the solar industry, and work with reliable solar energy companies in Chicago. Always choose verified Chicago solar installers.
Choosing the Right Solar Panel System Size
How many panels do I need for solar? Solar panels with higher power ratings can generate more energy than those with lower power ratings. Therefore, if you choose a panel with a higher power rating, you will need to install fewer panels!
How many solar panels are needed to cover the average household energy consumption, depending on the panel’s power rating? Let’s explore further.
| Panel Power Rating | Number of Panels Needed for Average Energy Consumption |
| 250 W | 26 |
| 300 W | 22 |
| 350 W | 19 |
| 400 W | 17 |
| 450 W | 15 |
250-watt panels are rarely used in new rooftop solar installations in 2024. It is worth considering solar panels with higher power ratings to meet primary energy needs. Panels rated at 250 and 300 watts are useful for small solar projects. Popular panel sizes typically range from 400 to 430 watts.
Environmental Benefits of Solar Power Chicago
Solar panels generate solar energy from renewable sources, which is better for the environment compared to energy from fossil fuels. During the conversion of sunlight into energy, no harmful substances are released into the atmosphere.
However, solar panels are not completely clean. The production and disposal of solar panels have their own environmental impacts. With industry advancements and improvements in solar panel recycling, we hope for the development of even more eco-friendly solar technologies!

There is also the option of financing solar panels in Chicago, which allows you to avoid significant upfront costs (free solar panels in Chicago) and instead pay for solar energy through monthly payments that better fit your lifestyle. For more details, you can check out the article "Solar Panel Lease in Chicago".
Are solar panels worth it in Chicago?
Chicago is indeed great for solar energy! It averages 135 peak sunlight hours per month. Considering that sunny states have about 210 hours (Arizona) and gloomy ones have 90 hours (Alaska), this city has an average rating and is favorable for installing solar panels.
What kind of rebates and incentives does Chicago offer for solar?
Illinois does not offer local tax exemptions for solar energy. However, residents can take advantage of the federal investment tax credit, which provides a 30% discount on your solar panel installation costs.

The "Solar Chicago" bulk purchasing program was launched in July through an initiative by the City of Chicago and partners Cook County, the World Wildlife Fund, the Environmental Law and Policy Center, and the Vote Solar Initiative.
This program is designed to make rooftop solar energy more accessible than ever for Chicago residents. The launch of this program was made possible after Mayor Emanuel announced on March 17, 2014, that Chicago became the Earth Hour Capital, winning a grant to promote the city's solar market development.
