Factors that Affect Solar Panel Costs in LaSalle
There are many criteria that can play into your total installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar panels.
Solar Equipment
Solar system size, which is measured in kilowatts, is one of the largest factors that influences the overall cost of installing solar panels. For that reason, it’s crucial to accurately assess the size of the solar energy system needed for your home by figuring out your typical energy use.The kind of solar panels and equipment you want is another factor that will greatly affect costs. Solar panels that are more efficient, like monocrystalline panels, tend to come at a higher price. Moreover, solar equipment is more than just the solar panels themselves. You’ll also need to consider the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when looking for a solar system that falls within your budget.
Solar Financing Terms
Many homeowners find the average cost of solar in LaSalle to be prohibitively steep, even if the investment pays off over time. Thankfully, almost every solar company in the area offers financing options. Solar loans drastically decrease upfront costs in most cases, but they also lead to paying more over time because of interest.While solar loans make going solar more accessible for LaSalle homeowners, they can also increase the total you pay for your system due to interest. If you put down a larger down payment, though, you can avoid paying as much in interest.
Solar Panel Installation Company
A final consideration when trying to evaluate the cost of solar for your home or business in LaSalle is the company you choose to install your PV system. As with choosing a company to renovate your kitchen, for example, there are plenty of solar installers that provide a range of services for different budgets.The size of the company can sometimes play the most considerable role in your costs. Larger national companies, like SunPro and Sunrun, often have lower pricing due to access to greater resources and better 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 discount can bring their pricing lower to compete with bigger names.

How to Save on Solar Panels
The solar installer you opt for will be a major factor in determining not only your total costs, but also the kinds of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are a few important things you should consider, including:
- Contract: It’s important to read through your solar installer’s contract fully to understand what services they will provide, what the warranty covers and what expectations you should have about your solar system’s energy production.
- Solar Panel Brands: Not all solar installers carry the same brands of solar panels, so the brand and type of panel you want can play a large role in the company you go with.
- Reputation: Your solar installer should have a good reputation as a company and have demonstrated expertise in the field. Two ways to check this are to look for whether a company has technicians certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it has good reviews from previous customers.
- Installation Process: Get details from your solar company about the installation process and what to expect, including when the site survey will be done and what the project timeline is.
EcoWatch's LaSalle, IL Solar Cost FAQs
What is the average cost of installing solar panels in LaSalle?
This is a tough question to answer precisely, because the cost depends on a few different 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. It will cost more if you want additional solar equipment or higher quality panels, or if you have above-average energy usage. On the flip side, you can spend less if you go with a smaller solar panel system or less efficient solar panels.
Can you get solar panels for free in LaSalle?
A solar panel system isn’t free in LaSalle, 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 help lower the cost.
Can solar panels completely eradicate my power bills?
It is possible to eliminate your electricity bills with solar panels, but for most homeowners in LaSalle, that will require at least a 10-kW system. Not all homes will have roofs that 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 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 their energy production will have decreased significantly after that point. You can replace them once you've had them for that long or you can continue to use them at a lower efficiency.
