Factors that Affect Solar Panel Costs in Mount Prospect
There are several criteria that can determine your solar system installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that performs the installation.
Solar Equipment
The cost of solar panel systems varies by thousands of dollars due to a few different factors. One of the main factors is the system size, which is measured in kilowatts (kW). Solar power systems that have better efficiency or power production require better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $2,730. There are many different solar panel brands and the one you pick also changes the cost. Usually, the brands that offer higher efficiency tend to also cost more. Additionally, the type of equipment you're looking to get can affect your total cost. If you only need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
Many homeowners find the average cost of solar in Mount Prospect to be prohibitively costly, even if the investment pays off over time. Thankfully, nearly every solar installer in the area provides financing options. Solar loans greatly decrease upfront costs in most cases, but they also result in paying more over time due to interest. You'll have to consider the long-term cost of financing options, including the total interest you'll pay over the length of the loan. If you can only get a high-interest loan, then your total can be hundreds or even thousands of dollars more than the original cost. Making a larger down payment or getting a solar loan with a low interest rate could reduce your costs significantly.
Solar Panel Installation Company
The last significant cost factor you should take into consideration is the installer you choose. Given the booming popularity of green energy solutions in Mount Prospect, you'll have plenty of options to choose from, but each comes at different price points for labor and equipment. Companies that only sell high-quality, high-efficiency and high-price products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come at a higher cost. It's best to do some research and decide on the company that has the products, warranties and services you're looking for and also fits within your budget.

How to Save on Solar Panels
The company that does your solar panel installation will affect the warranties and brands you have access to, and it will also have an impact on your total cost. Since choosing a company can be a challenge, we have some tips to help you, such as:
- Solar Panel Brands: Homeowners will have different preferences for panels based on their roof configurations and energy needs. While there are many options for which brand of solar panel you can get, not every company will have the exact one you may want or need, so make sure you ask for their list of options before deciding.
- Warranty: Many companies offer different kinds of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.
- Contract: When reading through your solar company's contract, ask questions about any terms you're not sure of and be sure you understand what happens in scenarios like a system part breaking or if the company goes out of business.
- Reputation: Solar companies that have great reviews from their customers and that have been in business for many years most likely provide good-quality solar panel installation and expertise.

EcoWatch's Mount Prospect, IL Solar Cost FAQs
What is the average cost of installing solar panels in Mount Prospect?
The average cost of solar panels in Mount Prospect is about $13,650 for a 5-kW system and $27,300 for a 10-kW system before the ITC, but the actual cost will depend on stuff such as the kind of solar panels you want, what size system you need and how much energy you use.
Is it better to lease or buy solar panels in Mount Prospect?
Leasing solar panels can be an attractive choice, because it commonly comes with low or $0 upfront payments. The downside is that you won't be able to save as much. If you lease, you don't own the system, so you can't claim any tax rebates and credits and your home value won't increase. Buying solar panels is a better way to go if you want to maximize your savings.
How much can I save on energy bills after switching to solar?
It is possible to eradicate your electricity bills with solar panels, but for most homeowners throughout Mount Prospect, that will require at least a 10-kW system. Not all homes can accommodate that size system, so you'll want to check with a local solar installer to see how many panels can fit on your roof.
How many solar panels should I get to power my home?
The exact number of solar panels you need depends on your household energy consumption and the average daily sunlight your roof gets. You can take a look at your energy bills for the past year to get an idea of the solar system size you'll need. The average household has to install between 20 and 35 panels to account for their typical energy usage.
