Factors that Affect Solar Panel Costs in Delaware

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

Solar Equipment

System size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of installing solar panels. That's why it's a priority to accurately ascertain the size of the solar energy system needed for your home by figuring out your energy needs. There are several different solar panel brands and the one you pick also changes the cost. Generally, 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 just need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

Many homeowners find the average cost of solar in Delaware to be prohibitively expensive, even if the investment pays off over time. Thankfully, nearly every solar installer in the area offers financing options. Solar loans greatly decrease upfront costs for most homeowners, but they also result in higher prices over time due to interest. When estimating your overall cost, you should also calculate the interest you'll pay if you choose to go with a solar loan. Also, paying more on your down payment can lower the total interest paid over time.

Solar Panel Installation Company

A final factor to consider when trying to evaluate the cost of solar for your home or business in Delaware is the company you hire to install your solar system. Similar to choosing a company to build a deck or pool, for instance, there are plenty of solar installers that offer a range of services for different budgets. Companies that only sell high-efficiency and high-priced products — 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 decide on the company that offers the products, warranties and services you want and also is within your budget.

How to Save on Solar Panels

There are a large number of companies available in Delaware, and some homeowners feel overwhelmed considering their options. Choosing the right company for you can be challenging, so here are some tips to help you decide:

  • Reputation: Solar system installers that have great reviews from their customers and that have been in business for many years likely provide quality solar panel installation and expertise.
  • Solar Panel Brands: The type of solar panel you'd like to install plays a role in which installer you should opt for, since different companies have access to different panels.
  • Contract: When looking over your solar installer's contract, ask for clarification about any terms you're not sure of and be sure you understand what happens in scenarios such as a system part breaking or if the company goes out of business.
  • Warranty: Warranties that provide coverage for replacement parts and repairs over a couple decades are the best you can get in the business, and offering that kind of warranty is one sign of a quality company.
