Factors that Affect Solar Panel Costs in Chester

There are several 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 does the installation.

Solar Equipment

One of the most significant factors to consider when it comes to the cost of adopting solar energy is the size of the solar system, which is measured in kilowatts (kW). The more energy your household uses, the larger your system will likely need to be. You can expect to pay around $3,760 per kilowatt in Chester.Some solar panel brands — like Maxeon from SunPower — cost more upfront but also tend to offer higher efficiency. In a city like Chester, where sunlight is relatively abundant, efficiency can quickly pay off. Plus, 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

Many homeowners find the average cost of solar in Chester to be too expensive, even if the investment pays off over time. Thankfully, almost every solar company in the area provides access to financing options. Solar loans substantially decrease upfront costs in most cases, but they also result in paying more over time due to interest.When figuring out your overall cost, you should also calculate the interest you’ll pay if you decide on a solar loan. Also, paying more upfront can reduce the total interest paid over time.

Solar Panel Installation Company

Lastly, the company you get to install your solar panels can influence your pricing. Chester’s solar companies all have different labor costs and add varying upcharges to equipment. Larger national companies typically have lower costs, but some local companies undercut them by promoting sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or extra services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels

Since the model of solar panels and the installer you choose has an impact on your costs and your system’s durability and efficiency, it’s important to select the right ones for you. Here are some tips to keep in mind to help with your decision:

  • Solar Panel Brands: Each solar panel brand and model has varying levels of quality, durability and efficiency. They will come at different costs as well. The company you choose plays a role in which solar panel brands you have access to.
  • Installation Process: When going solar, it’s crucial to maintain an open line of communication with your solar panel company. See to it that you understand how the installation process works and the project completion timeline.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for sustainable energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a solid reputation and is qualified to install your solar system. Another way you can look into your installer’s reputation is by reading reviews.
  • Warranty: A comprehensive, 25-year warranty can help keep your solar system running for a long time and save you money on part replacement and repairs.

EcoWatch's Chester, IL Solar Cost FAQs

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

The average cost of solar panels in Chester 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 certain factors like the type of solar panels you want, what size system you need and how much energy you consume.

Is it better to lease or buy solar panels in Chester?

Leasing solar panels can be an option if you can’t pay upfront or get a solar loan, but since you don’t own the system, you don’t have access to many solar incentives. Also your property value won’t increase, so you’ll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most financial benefits from going solar.

Does Chester have a net metering program?

Most states have net metering programs of some kind. Through these, you can get paid for the extra power your system generates or or receive credits to put toward future utility bills. Currently there are just three states that don’t have any net metering laws: Alabama, Tennessee and South Dakota.

What solar power system size is right for my home?

To figure out how many solar panels you need, you should find out how much energy your home requires and how much sunlight your home gets. For a general estimate, however, since each panel can usually produce about 250 to 400 watt-hours per hour, the average household will need 20 to 35 panels.
