Factors that Affect Solar Panel Costs in St Clair

Cost is usually one of the most important factors for homeowners who want to invest in solar. There are a few primary factors that will push your cost above or below the average in St Clair: solar equipment and system size, financing options and the solar installation company you choose. We'll discuss each of these briefly below.

Solar Equipment Size

One of the most significant factors to consider when it comes to the cost of installing solar panels is the size of the solar system, which is measured in kilowatts (kW). The more electricity your household consumes, the larger your system will likely need to be. You can expect to pay about $2,730 per kilowatt in St Clair. There are a lot of different solar panel brands and the one you pick also affects the cost. In many cases, the brands that offer higher efficiency tend to also be more expensive. Plus, the type of equipment you choose 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

Most solar companies in St Clair offer solar loans, which reduce the initial cost of installing solar. Although solar loans make adopting solar energy more accessible for St Clair homeowners, they can also increase the total you pay for your system, depending on your interest rate and how long you take to pay off the loan. If you make a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

The remaining significant cost factor you should take into consideration is the installer you choose. Given the booming popularity of renewable energy solutions in St Clair, you'll have lots of options to choose from, but each comes at varying price points for labor and equipment. You may see national solar installers that have lower prices because of their bigger brand name and access to bulk equipment prices, or you might see small, local installation companies offering deals or promotions to compete with those larger companies.

How to Save on Solar Panels

Since the type of solar panels and the installer you choose significantly impacts your costs and your system's durability and efficiency, it's important to select the right ones for you. Here are some things to keep in mind to help with your decision:

  • Solar Panel Brands: Homeowners will have different preferences for panels depending on their roof configurations and how much efficiency they need. Even though there are many options for which brand of solar panel you can get, not every company will have the exact one you may want or need, so make sure you take a look at their list of options before making your decision.
  • Warranty: An all-inclusive, 25-year warranty can help keep your solar panels running for a long time and save you money on part replacement and repairs.
  • Reputation: Companies that have been operating for many years likely have a high reputation. This is important because it ensures that it will not only see your solar installation through, but will also provide adequate aftercare and customer support, such as part repairs and replacements.
  • Contract: When looking over your solar installer's contract, ask questions about any terms you're not sure of and make sure you understand what happens in scenarios such as a system component breaking or the company going out of business.

EcoWatch's St Clair, IL Solar Cost FAQs

How much does it cost to install solar panels in St Clair?

The average cost of solar panels in St Clair is about $13,650 for a 5-kW system and $27,300 for a 10-kW system before the ITC, but the real cost will depend on things like the type of solar panels you want, what size system you need and how much energy you use.

What other factors should I consider other than cost when buying solar panels?

The upfront cost is a very important factor to consider, but whether it's the most important for you depends on why you decided to go solar. In places where rooftop space is limited, efficiency can trump the cost. Other factors that are important to consider are the quality and durability of your solar panels.

Is switching to solar power worth it?

Solar panels can be a fruitful investment for many homeowners, but they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight and/or your power bills are already reasonably low, solar panels might not be for you.

What solar power system size is right for my home?

The exact number of solar panels you need depends on your household energy needs and the amount of sunlight your roof gets. You can take a look at your energy bills for the past year to get an idea of the solar system size you'll need. The average household has to install between 20 and 35 panels to account for their typical energy usage.
