Factors that Affect Solar Panel Costs in Dekalb

There are many criteria that can play into your solar panel installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar system.

Solar Equipment

Solar system size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of installing solar panels. Because of that, it's important to accurately gauge the size of the solar energy system needed for your home by figuring out your energy needs. Some solar brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer higher efficiency. In a city like Dekalb, where sunlight is relatively abundant, efficiency can quickly pay off. Also, if you have a small roof or you don't have a lot of space for your panels, higher efficiency options will be more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

For some homeowners, paying for a solar system out of pocket can be a challenge. Solar loans are offered by most installers in Dekalb, which can lower, or in some cases totally eliminate, your upfront costs to make solar more affordable. 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 principal cost. Making a larger down payment or securing a solar loan with a low interest rate could reduce your costs significantly.

Solar Panel Installation Company

A final factor to keep in mind when trying to estimate the cost of solar for your home or business in Dekalb is the company you choose to install your solar panel system. As with choosing a company to install new cabinets, for example, there are plenty of solar installers that provide a range of services at different price points. You may come across national solar installers that have lower prices because of their bigger brand name and access to bulk pricing, or you might see small, local installation companies offering deals or promotions to compete with those major players.

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. Because selecting a company can be a tough decision, we have some tips to help you, such as:

  • Warranty: Each company may offer different kinds of warranties that provide different kinds of coverage. A 25-year, all-inclusive warranty is the gold standard.
  • Reputation: Your solar installer should have a good reputation as a company and have proven expertise in the field. A couple of ways to check this are to look for whether a company has technicians that hold a certification from the North American Board of Certified Energy Practitioners (NABCEP) and if it has good reviews from past customers.
  • Solar Panel Brands: Different companies have different brands and kinds of panels. If you want a specific brand, make sure the solar panel installer you're considering has it.
  • Contract: It's important to read through your solar installer's contract closely to understand what services they will provide, what the warranty covers and what you can expect about the cost.

EcoWatch's Dekalb, IL Solar Cost FAQs

What is the average cost of installing solar panels in Dekalb?

This is a tough question to answer exactly, because the cost depends on a few different factors. Generally speaking, it costs about $13,650 for a 5-kW system and $27,300 for a 10-kW system after the ITC is applied. You can expect to pay more if you want additional solar equipment or higher quality panels, or if you have higher-than-average energy needs. On the other hand, you can spend less if you choose a smaller solar panel system or cheaper solar panels.

Should I lease or buy solar panels in Dekalb?

Leasing solar panels can be an appealing choice, because it usually 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 get the most savings.

Is it worth going solar in Dekalb?

Whether or not solar panels are worth it depends on a variety of factors like how much you pay for electricity and the amount of direct sunlight your roof gets.

How often do you have to replace solar panels?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely at that time. What this means is how much energy they produce will have decreased significantly after that point. You can opt to replace them after having them for that long or you can keep using them at a lower efficiency.
