Factors that Affect Solar Panel Costs in Duncan

The cost of installing a solar system in Duncan can vary by more than $10,000 from home to home. Your actual cost is dependent on several factors. The most significant one is your system size, and other factors include equipment choices, financing options and the solar company you choose.

Solar Equipment

The cost of solar panels varies by thousands of dollars due to a few different factors. One of the most significant factors is the system size, which is measured in kilowatts (kW). Solar power systems that have higher efficiency or power production require better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $2,620. The type of solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you get 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 power bills. In addition, add-on products, like solar batteries, can bring your total well above the Duncan average.

Solar Financing Terms

Many homeowners find the average cost of solar in Duncan to be too steep, even if the investment pays off over time. Fortunately, nearly every solar installer in the area provides financing options. Solar loans drastically decrease upfront costs for most homeowners, but they also result in a higher cost over time because of interest. You'll have to consider the long-term cost of financing options, including the amount of interest you'll pay over the length of the loan. If you're only able to get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or getting a solar loan with a low APR could reduce your costs remarkably.

Solar Panel Installation Company

A final factor to consider when trying to evaluate the cost of solar for your home or business in Duncan is the company you hire to install your solar panel system. As with 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 cost more. It's best to do some research and go with the company that has the products, warranties and services you want and also fits within your budget.

How to Save on Solar Panels

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

  • Warranty: A comprehensive, 25-year warranty can help keep your solar panels running smoothly and save you money on repairs and maintenance.
  • Solar Panel Brands: Each solar panel brand and kind offers varying levels of quality, durability and energy efficiency. They will come at different price points as well. The company you choose has an impact on which solar panel brands you have access to.
  • Reputation: Make sure your solar panel installer has a good reputation by confirming it has certifications and licenses, checking how long it's been in business and reading reviews by previous customers and solar experts like the EcoWatch team.
  • Contract: Look through the contract terms thoroughly to make sure you understand how much it will cost, project timeline incentives and warranties.
