Factors that Affect Solar Panel Costs in Romeoville
Although the average cost of a solar system in Romeoville is $16,997, your final cost may be above or below the average. There are many factors that can have a major impact on the cost of a solar panel installation. Below are some of the more crucial things to consider.
Solar Equipment
When it comes to estimating the price of a solar system in Romeoville, one of the most important 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 consumption, which you can determine by looking at past electricity bills. Your total cost can increase by about $3,760 for each additional kilowatt you need.The brand and type of equipment you get for your solar system can increase or decrease the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these are often more expensive than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have a small roof or just want maximum energy production, you can expect a higher equipment cost, but this can typically lead to greater savings over time. Plus, if you want add-ons like an electric vehicle charger or solar batteries, this will also increase the cost.
Solar Financing Terms
Many homeowners find the average cost of solar in Romeoville to be too expensive, even if the investment pays off over time. Fortunately, almost every solar installer in the area provides financing options. Solar loans substantially decrease upfront costs in most cases, but they also lead to higher prices over time because of interest.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 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 finding a solar loan with a low APR could reduce your costs remarkably.
Solar Panel Installation Company
The solar panel installer you select will affect your total cost to adopt solar energy. Different companies will bill different amounts for the equipment and labor.The company’s size can sometimes play the most considerable role in the cost. Larger national companies, like SunPro and Sunrun, often have lower pricing because they have access to more 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 down to compete with bigger companies.

How to Save on Solar Panels
The solar panel company you opt for will impact not only your overall costs, but also the types of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are a few important things you should keep in mind, such as:
- Warranty: Many companies offer different kinds of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.
- Contract: Before you sign a contract with a solar installer, be sure to look it over fully so you understand the terms. Also, ask questions if you’re unsure about some of the terms, such as what the warranty covers and if there are any guarantees about energy production.
- Reputation: Your solar installer should have a sound reputation as a company and have verifiable 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 satisfied reviews from previous customers.
- Solar Panel Brands: The model of solar panel you’d like to get plays a role in which installer you should go with, since different companies have different panels.

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 extra solar equipment or higher quality panels, or if you have higher-than-average energy usage. On the other hand, you can spend less if you go with a smaller solar panel system or cheaper solar panels.

How often do you have to replace solar panels?
