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

When it comes to estimating the price of solar panels in St Clair, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are mainly based on your home's energy usage, which you can gauge by looking at past electricity bills. Your overall cost can increase by about $2,730 for each additional kilowatt you need. The solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you opt for the most efficient solar panel brands, you'll end up paying more upfront than if you opted for the most affordable panels. However, more efficient panels could save you more over time on your electric bills. Additionally, extra products, like solar batteries, can bring your total well above the St Clair average.

Solar Financing Terms

For some homeowners, paying for solar out of pocket can be difficult. Solar loans are provided by most installers in St Clair, which can lower, or in some cases totally eliminate, your upfront costs to make solar more affordable. Though solar loans make going solar more accessible for St Clair homeowners, they can also add to the total you pay for your system due to interest. If you make a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

The solar installation company you select will impact your total cost to adopt solar power. Different companies will charge different amounts for the equipment and labor. Additionally, some companies in St Clair have more knowledge about local solar incentives and can help you learn about additional rebates or tax exemptions. However, they may charge more for walking you through the whole process. Even if they cost more upfront, they could end up saving you more money in the long run.

How to Save on Solar Panels

The company that does your solar panel installation will affect the warranties and brands you have access to, and it will also have an impact on your total cost. Since choosing a company can be a tough decision, we have some tips to help you, such as:

  • Solar Panel Brands: Not all solar companies offer the same brands of solar panels, so the brand and type of panel you want can play a substantial role in the company you opt for.
  • Warranty: Warranties that cover panel repairs and maintenance over around 25 years are the best you can get in the business, and offering such a warranty is one sign of a good company.
  • Contract: Even though reading through a contract can be tedious, it's important to do it carefully so you can be sure you understand what services your solar company will provide and the terms of the warranty.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a good reputation and is qualified to do the job well. Another way you can research your installer's reputation is by reading reviews.

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 actual cost will depend on things such as the type of solar panels you want, what size system you need and how much energy you consume.

Should I lease or buy solar panels in St Clair?

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 savings from going solar.

Can you sell solar power back to the grid in St Clair?

Most states offer net metering programs of some kind. Through these, you can be compensated 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.

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 how much energy they produce 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.
