Factors that Affect Solar Panel Costs in Delaware

There are several criteria that can affect your solar system 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 significant factors to consider when it comes to the cost of adopting solar energy is the size of the solar system, which is measured in kilowatts (kW). The more electricity your household consumes, the larger your system will likely need to be. You can expect to spend around $3,530 per kilowatt in Delaware.The brand and type of equipment you get for your solar system can increase or decrease the price quite significantly. If you prefer a brand name like Tesla or SunPower, these often have a higher price tag than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have limited roof space or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to greater savings over time. Also, if you want add-ons like an electric vehicle charger or solar batteries, this will also raise the cost.

Solar Financing Terms

Many homeowners find the average cost of solar in Delaware to be prohibitively steep, even if the investment pays off over time. Thankfully, nearly every solar company in the area provides access to financing options. Solar loans remarkably decrease upfront costs for most homeowners, but they also lead to paying more over time because of interest.However, the interest on solar loans also adds to your all-in costs, so it’s vital to include that in your estimate as well. You can always lower the total you pay in interest and sometimes even your APR by putting more money down.

Solar Panel Installation Company

The solar installer you choose to handle your switch to sustainable energy can have an effect on your total costs. There are about 3 solar installation companies in Delaware, and each can charge different amounts for labor and equipment.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 come at a higher cost. It’s best to do some research and go with the company that provides the products, warranties and services you’re looking for and also fit into your budget.

How to Save on Solar Panels

The solar company you choose will affect not only your total costs, but also the types of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are a few important things you should take into account, including:

  • Warranty: A quality company stands out from other companies by providing the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
  • Solar Panel Brands: Homeowners will have different preferences for panels based on their roof configurations and energy needs. Although there are many options for which brand of solar panel you can get, not every company will have the exact one you may want or need, so make sure you take a look at their list of offerings before making your decision.
  • Contract: Though reading through a contract can be tedious, it’s important to do it fully so you can be sure you understand how much the equipment and services will cost and the terms of the warranty.
  • Reputation: Make sure your solar system installer has a good reputation by confirming it has certifications and licenses, checking its number of years in business and reading reviews by past customers and solar experts like the EcoWatch team.
