Factors that Affect Solar Panel Costs in Rock Falls
Though the average cost of a solar system in Rock Falls is $17,039, your actual cost may differ. There are many factors that can have a major impact on the cost of a residential solar panel installation. Below are some of the more important things to keep in mind.
Solar Equipment
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 uses, the larger your system will likely need to be. You can expect to pay about $3,760 per kilowatt in Rock Falls.Some solar brands — like Maxeon from SunPower — cost more upfront but also tend to offer higher efficiency. In a city like Rock Falls, where sunlight is relatively abundant, efficiency can quickly pay off. In addition, if you have a small roof or limited space for your panels, higher efficiency options will be a better option. 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 Rock Falls to be prohibitively costly, even if the investment pays off over time. Fortunately, almost every solar installer in the area offers financing options. Solar loans remarkably decrease upfront costs for most homeowners, but they also lead to higher prices over time because of interest.Even though solar loans make adopting solar energy more accessible for Rock Falls homeowners, they can also add to the total you pay for your system due to interest. If you put down a larger down payment, though, you can avoid paying as much in interest.
Solar Panel Installation Company
The final key cost factor you should consider is the installer you choose. Given the booming popularity of renewable energy solutions in Rock Falls, you’ll have plenty of options to choose from, but each comes at different price points for labor and equipment.Some companies only sell high-efficiency and high-priced products — 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 find a company that provides the products, warranties and services you’re looking for and also is within your budget.
