There are a number of factors that significantly influence the price you’ll pay, which we'll go over below.
Solar Equipment
One of the most important factors to consider when it comes to the cost of going solar is the size of the solar system, which is measured in kilowatts (kW). The more electricity your household consumes, the larger your system will likely need to be. You can expect to spend about $3,760 per kilowatt in Waterloo.The solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you get the most efficient solar panel brands, you’ll end up paying more upfront than if you opted for the most affordable panels. On the other hand, more efficient panels could save you more in the long run on your electric bills. In addition, extra products, such as solar batteries, can bump up your total well above the Waterloo average.
Solar Financing Terms
Solar panels can save you money on energy bills over many years, but they can also be a big investment. That’s why many Waterloo homeowners choose to finance their solar panel systems to make paying for solar more affordable.You’ll have to consider the long-term cost of loans, including the amount of interest you’ll pay over the length of the loan. If you’re only able to 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 finding a solar loan with a low interest rate could reduce your costs significantly.
Solar Panel Installation Company
The solar panel installation company you select will affect your total cost to adopt solar energy. Different companies will charge different amounts for the equipment and labor.Companies that only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come with an above-average cost. It’s best to do some research and go with the company that has the products, warranties and services you’re looking for and also fit into your budget.

EcoWatch's Waterloo, IL Solar Cost FAQs
What is the average cost of installing solar panels in Waterloo?
The average cost of solar panels in Waterloo is about $18,800 for a 5-kW system and $37,600 for a 10-kW system before the ITC, but the real cost will depend on things such as the type of solar panels you want, what size system you need and how much energy you use.
Should I lease or buy solar panels in Waterloo?
Leasing solar panels can be an attractive choice, because it often comes with low or $0 upfront payments. The drawback 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 power bills after installing solar panels?
It is possible to eliminate your electricity bills with solar panels, but for most homeowners in Waterloo, that will require at least a 10-kW system. Not all homes will have the roof space for 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 usage and how much sunlight your roof gets. You can 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 buy between 20 and 35 panels to cover their typical energy usage.
