Factors that Affect Solar Panel Costs in Johnsburg
Cost is typically one of the most important factors for homeowners who want to invest in solar. There are a few major factors that affect your total cost in Johnsburg: solar equipment and system size, financing options and the solar installation company you choose. We’ll go over each of these briefly below.
Solar Equipment
When it comes to estimating the cost of solar panels in Johnsburg, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are largely based on your home’s energy usage, which you can figure out by looking at past power bills. Your total cost can increase by around $3,760 for each additional kilowatt you need.There are many different solar panel brands and the one you pick also changes the cost. Generally, the brands that are more efficient tend to also cost more. Plus, the type of equipment you’re looking to install can affect your total cost. If you just 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 Johnsburg to be prohibitively steep, even if the investment pays off over time. Fortunately, nearly every solar company in the area offers financing options. Solar loans greatly decrease upfront costs in most cases, but they also result in higher prices over time because of interest.However, the interest on solar loans also increases your total costs, so it’s vital to include that in your estimate as well. You can always bring down the total you pay in interest and possibly even your APR by making a larger down payment.
Solar Panel Installation Company
A final consideration when trying to figure out the cost of solar for your home or business in Johnsburg is the company you get to install your solar panel system. As with choosing a company to renovate your kitchen, for example, there’s no shortage of solar installers that provide a range of services for different budgets.The size of the company sometimes plays the most considerable role in the cost of installation. Larger national companies, like SunPro and Sunrun, often have lower pricing because of more resources and bulk pricing. Smaller local companies might be more costly, but they can sometimes have better customer service and more customization options, and the occasional sale or promotion can bring their pricing lower to compete with bigger names.

How to Save on Solar Panels
There are numerous companies to choose from in Johnsburg, and some homeowners feel overwhelmed considering their options. Choosing the right company for you can be challenging, so here are some tips to help you decide:
- Reputation: Companies that have been in business for many years likely have a high reputation. This is important because it ensures that it will not only see your solar project through, but will also provide quality aftercare and customer support, such as part repairs and replacements.
- Installation Process: Get details from your solar company about the installation process and what to expect, such as when the site survey will be completed and how long it will take.
- Warranty: Warranties that cover replacement parts and repairs over a long period of time such as 25 years are the best you can get in the business, and offering that kind of warranty is one sign of a good company.
- Solar Panel Brands: Different companies will carry different brands and kinds of panels. If you know you want a specific brand, make sure the solar installer you’re considering has it.
EcoWatch's Johnsburg, IL Solar Cost FAQs
What is the average cost of installing solar panels in Johnsburg?
This is a tough question to answer precisely, because the cost depends on a variety of factors. Broadly speaking, it costs about $18,800 for a 5-kW system and $37,600 for a 10-kW system after the ITC is applied. You can expect to pay more if you want extra solar equipment or higher quality panels, or if you have above-average energy needs. Conversely, you can spend less if you want a smaller solar panel system or cheaper solar panels.
Are solar panels free in Johnsburg?
Solar panels aren’t free in Johnsburg, but there are some options that can make getting them more feasible, such as leasing solar panels or getting a solar loan. There may also be local programs or incentives that can further reduce the cost.
Can solar panels eliminate my power bills?
It is possible to erase your electricity bills with solar panels, but for most homeowners in Johnsburg, 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 contact a local solar installer to see how many panels can fit on your roof.
How long do solar panels last in Johnsburg?
Although 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 their energy production 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.
