Factors that Affect Solar Panel Costs in Delaware

Cost is typically one of the most important factors for homeowners wanting to invest in solar. There are a few primary factors that will push your cost above or below the average in Delaware: solar equipment and system size, financing options and the solar installation company you choose. We'll go over each of these briefly below.

Solar Equipment

When it comes to estimating the price of a solar panel system in Delaware, one of the most important 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 figure out by looking at past electricity bills. Your total cost can increase by about $2,550 for each additional kilowatt you need. The type of solar panels and equipment you want is another factor that will greatly influence costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to come at a higher price. Plus, solar equipment goes beyond just the solar panels themselves. You'll also need to decide on 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 installers in Delaware offer solar loans, which reduce the initial cost of installing solar. Though solar loans make going solar more accessible for Delaware homeowners, they can also increase the total you pay for your system due to interest. If you put down a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

The solar panel installer you select will impact your total cost to adopt solar power. Different companies will bill different amounts for the equipment and labor. Larger national companies usually have lower costs, but some local companies undercut 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 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. Since choosing a company can be a tough decision, we have some tips to help you, such as:

  • Reputation: Make sure your solar company has a good reputation by verifying it has certifications and licenses, checking its number of years in business and reading reviews by previous customers and solar experts like the EcoWatch team.
  • Contract: Review the contract terms carefully to make sure you understand how much it will cost, completion timeline rebates and warranties.
  • Solar Panel Brands: Different companies offer various brands and kinds of panels. If you know you want a specific brand, make sure the solar company you're considering has it.
  • Warranty: A quality company rises above other companies by providing the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.

EcoWatch's Delaware, PA Solar Cost FAQs

What is the average cost of installing solar panels in Delaware?

This is a tough question to answer precisely, because the cost depends on a few different factors. Broadly speaking, it costs about $12,750 for a 5-kW system and $25,500 for a 10-kW system after the ITC is applied. It will be more expensive if you want extra solar equipment or more efficient panels, or if you have higher-than-average energy consumption. On the other hand, you can spend less if you want a smaller solar panel system or less expensive solar panels.

Is cost the most important consideration when buying solar panels?

Cost is definitely one of the most important factors you should consider when buying solar panels, but other important factors include efficiency, durability, and quality.

Does Delaware have a net metering program?

Most states offer net metering programs of some kind. Through these, you can receive compensation for the extra power your system produces or or receive credits to put toward future energy bills. Currently there are just three states that don't have any net metering laws: Alabama, Tennessee and South Dakota.

How long do solar panels last in Delaware?

On average, solar panels can last about 25 to 30 years. Some even last up to 50 years, but their efficiency decreases by about 0.8% each year. You can choose to replace them sooner if you want to maintain a higher amount of energy production.
