Factors that Affect Solar Panel Costs in Dover

Cost is often one of the most important factors for homeowners who want to invest in solar. There are a few primary factors that affect your total cost in Dover: solar equipment and system size, financing options and the solar installation company you choose. We’ll discuss each of these briefly below.

Solar Equipment

System size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of installing solar panels. Because of that, it’s crucial to accurately ascertain the size of the solar energy system needed for your home by figuring out your energy needs.The brand and kind of equipment you get for your solar system can raise or lower the price quite significantly. If you prefer a trusted 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 a small roof or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to more savings over time. Plus, if you want add-ons like an electric vehicle charger or solar batteries, this will also increase the cost.

Solar Financing Terms

If paying for solar panels out of pocket is too expensive, solar loans are a popular route because they decrease 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 lower the total interest paid over time.

Solar Panel Installation Company

The solar company you hire to handle your switch to clean energy can have an effect on your total costs. There are about 3 solar panel companies operating in Dover, and each can charge varying amounts for labor and equipment.The company’s size can sometimes play the most significant role in the cost. Larger national companies, like SunPro and Sunrun, often have lower pricing due to greater 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 promotion can bring their pricing lower to compete with bigger names.

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 picking a company can be difficult, we have some tips to help you, such as:

  • Installation Process: One of the most important things to understand when adopting solar power is the installation process itself. Be sure to align on any details you should know with your solar company, such as what permits you should secure and how long the project will take.
  • Contract: It’s important to read your solar installer’s contract closely to understand what services they will provide, what the warranty covers and what expectations you should have about the installation process.
  • Reputation: Make sure your solar company has a good reputation by verifying it has certifications and licenses, checking how long it's been in business and reading reviews by previous customers and solar experts like the EcoWatch team.
  • Solar Panel Brands: Homeowners will have different preferences for panels based on their roof configurations and how much efficiency they need. Even though 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 peruse their list of options before deciding.

How often do you have to replace solar panels?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of at that time.
