Factors that Affect Solar Panel Costs in Wilmington

There are many criteria that can influence your total installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar system.

Solar Equipment

One of the most important factors to consider when it comes to the cost of going solar is the size of the solar system, which is measured in kilowatts (kW). The more power your household consumes, the larger your system will likely need to be. You can expect to spend about $2,580 per kilowatt in Wilmington. There are several different solar panel brands and the one you choose also changes the cost. In general, the brands that have better efficiency tend to also be more expensive. Additionally, the type of equipment you're looking to install can affect your total cost. If you only need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

If paying for solar panels in cash is out of reach, solar loans are a popular route because they reduce your upfront costs and let you pay for your system over five to seven years on average. When figuring out your overall cost, you should also calculate the interest you'll pay if you choose to go with a solar loan. Also, paying a higher down payment can reduce the total interest paid over time.

Solar Panel Installation Company

The solar company you choose will impact your total cost to go solar. Different companies will bill different amounts for the equipment and labor. The company's size can sometimes play the most significant role in the installation costs. Larger national companies, like SunPro and Sunrun, often have lower pricing because they have access to 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 discount can bring their pricing lower to compete with bigger companies.

How to Save on Solar Panels

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

  • Warranty: If you care about the longevity of your solar panels, making sure your company offers a 25-year, all-inclusive warranty can give you some peace of mind.
  • Contract: When looking over your solar company's contract, ask questions about any terms you're not sure of and be sure you understand what happens in scenarios such as a system component breaking or if the company goes out of business.
  • Reputation: Make sure your solar system installer has a good reputation by verifying it has certifications and licenses, checking its number of years in business and reading reviews by past customers and solar experts like EcoWatch.
  • Solar Panel Brands: Each solar panel brand and kind offers varying levels of quality, longevity and energy efficiency. They will come at different costs as well. The company you choose has an impact on which solar panel brands you have access to.
