There are many criteria that can influence your solar panel 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
When it comes to estimating the price of a solar panel system in Carol Stream, 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 energy bills. Your overall cost can increase by around $3,760 for each additional kilowatt you need.The solar equipment you choose can increase or decrease your cost by thousands or even tens of thousands of dollars. If you choose the most efficient solar panel brands, you’ll end up paying more upfront than if you opted for the most affordable panels. However, higher efficiency could save you more in the long run on your electric bills. Additionally, add-on products, such as solar batteries, can bump up your total well above the Carol Stream average.
Solar Financing Terms
Many homeowners find the average cost of solar in Carol Stream to be prohibitively costly, even if the investment pays off over time. Fortunately, almost every solar company in the area offers financing options. Solar loans substantially decrease upfront costs in most cases, but they also result in a higher cost over time due to interest.When trying to figure out your overall cost, you should also calculate the interest you’ll pay if you go with a solar loan. Also, paying more on your down payment can reduce the total interest paid over time.
Solar Panel Installation Company
A final factor to consider when trying to estimate the cost of solar for your home or business in Carol Stream is the company you choose to install your solar system. Similar to choosing a company to install new cabinets, for example, there are plenty of solar installers that offer a range of services for different budgets.Some companies only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come at a higher cost. It’s best to do some research and decide on the company that offers the products, warranties and services you want and also fit into your budget.
