Factors that Affect Solar Panel Costs in Marathon
Cost is typically one of the most important factors for homeowners who want to invest in solar. There are a few key factors that affect your total cost in Marathon: solar equipment and system size, financing options and the solar installation company you choose. We’ll cover each of these briefly below.
Solar Equipment
When it comes to estimating the price of a solar system in Marathon, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are chiefly based on your home’s energy consumption, which you can figure out by looking at past energy bills. Your total cost can increase by around $3,210 for each additional kilowatt you need.The kind of solar equipment you choose can increase or decrease your cost 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. On the other hand, higher efficiency could save you more over time on your electric bills. Additionally, add-on products, like solar batteries, can bring your total well above the Marathon average.
Solar Financing Terms
Many homeowners find the average cost of solar in Marathon to be too steep, even if the investment pays off over time. Fortunately, almost every solar installer in the area offers financing options. Solar loans drastically decrease upfront costs for most homeowners, but they also result in a higher cost over time because of interest.Although solar loans make adopting solar energy more accessible for Marathon homeowners, they can also add to the total you pay for your system, depending on your interest rate. If you make a larger down payment, though, you can cut back on how much interest you have to pay.
Solar Panel Installation Company
The final key cost factor you should keep in mind is the installer you choose. Given the massive popularity of clean energy solutions in Marathon, you’ll have a great number of options to choose from, but each comes at different price points for labor and equipment.The size of the company can sometimes play the most significant role in the installation costs. Larger national companies, like SunPro and Sunrun, often have lower prices due to access to greater resources and better pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or discount can bring their pricing lower to compete with bigger companies.
