Factors that Affect Solar Panel Costs in Deerfield
Although the average cost of a solar system in Deerfield is $16,730, your actual cost may differ. There are many factors that can have a sizable impact on the cost of a solar panel installation. Below are some of the more important things to take into consideration.
Solar Equipment
The size of the solar panel system you need for your household, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, your total will most likely increase by around $3,760. The solar equipment you choose can bring your price up or down 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, more efficient panels could save you more over time on your energy bills. In addition, add-on products, such as solar batteries, can bring your total well above the Deerfield average.
Solar Financing Terms
Many homeowners find the average cost of solar in Deerfield to be prohibitively costly, even if the investment pays off over time. Fortunately, almost every solar company in the area provides access to financing options. Solar loans greatly decrease upfront costs for most homeowners, but they also result in higher prices over time due to interest.Although solar loans make going solar more accessible for Deerfield homeowners, they can also add to the total you pay for your system, depending on your interest rate and how long you take to pay off the loan. If you put down a larger down payment, though, you can avoid paying as much in interest.
Solar Panel Installation Company
A final consideration when trying to estimate the cost of solar for your home or business in Deerfield is the company you get to install your solar system. Similar to choosing a company to install new cabinets, for instance, there are plenty of solar installers that offer a range of services at different costs.The size of the company sometimes plays the most significant role in the installation costs. Larger national companies, like SunPro and Sunrun, often have lower pricing because they have more 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 promotion can bring their pricing down to compete with bigger names.
