Factors that Affect Solar Panel Costs in Delaware

For many Delaware homeowners, the decision to install solar panels comes down to cost. However, the range of solar installation costs can be quite wide in Delaware, with typical prices between $20,000 to $40,000. There are a few factors that significantly influence the price you'll pay, which we'll go over below.

Solar Equipment

When it comes to estimating the cost of solar panels in Delaware, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are largely based on your home's energy usage, which you can gauge by looking at past energy bills. Your total cost can increase by about $2,550 for each additional kilowatt you need. The kind of solar panels and equipment you choose is another factor that will considerably impact costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to be more expensive. Plus, solar equipment goes beyond just the solar panels themselves. You'll also need to make decisions about the kind of racks used to mount the panels, inverters, solar batteries, etc. It's important to take all of this into consideration when researching a solar system that's in your budget.

Solar Financing Terms

Most solar companies in Delaware have solar loans, which reduce the initial cost of installing a solar system. It's a good idea to add the interest you'll pay in your final cost estimate. If you can afford to pay a higher down payment, you can reduce your total costs and the amount of time it'll take to pay back the loan.

Solar Panel Installation Company

The solar installer you pick will affect your total cost to adopt solar energy. Different companies will bill different amounts for the equipment and labor. Larger national companies typically have lower costs, but some local companies keep up with them by promoting sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or add-on services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels

The solar company you opt for will influence not only your overall costs, but also the kinds of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are several important things you should keep in mind, including:

  • Warranty: An all-inclusive, long-term warranty can help keep your solar system running smoothly and save you money on part replacement and repairs.
  • Contract: Before you sign a contract with a solar installer, make sure you read it through completely so you understand the terms. Also, ask questions if you're unsure about some of the terms, such as what to do if a component breaks or malfunctions and if there are any guarantees about energy production.
  • Solar Panel Brands: Different companies will have various brands and kinds of panels. If you know you want a specific brand, make sure the solar installer you're considering has it.
  • Reputation: Solar panel companies that have great reviews from their customers and that have been operating for many years most likely provide quality solar panel installation and expertise.
