Factors that Affect Solar Panel Costs in New London

Cost is usually one of the most important factors for homeowners considering investing in solar. There are a few key factors that affect your total cost in New London: 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

One of the most important 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 energy your household consumes, the larger your system will likely need to be. You can expect to spend around $3,880 per kilowatt in New London.The brand and type of equipment you want for your solar system can raise or lower 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 a small roof or just want maximum energy production, you can expect a higher equipment cost, but this can typically lead to more 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

Solar panels can save you money on energy bills over many years, but they can also be a big investment. That’s why many New London homeowners choose to finance their solar panel systems to make paying for solar more affordable.It’s wise 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 how long it’ll take to pay off the loan.

Solar Panel Installation Company

The final key cost factor you should take into consideration is the installer you choose. Given the growing popularity of sustainable energy solutions in New London, you’ll have plenty of options to choose from, but each comes at various price points for labor and equipment.You may come across national solar installers that have lower prices because of their larger brand name and access to bulk equipment pricing, or you might see small, local installation companies offering deals or promotions to compete with those major players.

How to Save on Solar Panels

Since the type of solar panels and the company you choose has an impact on your costs and your system’s durability and efficiency, it’s important to select the right ones for you. Here are some things to keep in mind to help with your decision:

  • Installation Process: Homeowners should understand how exactly the installation process will go, as well as important factors like the project timeline.
  • Contract: Before signing a contract with a solar installer, be sure to read it through fully so you understand the terms. Also, ask questions if you’re not sure about some of the terms, such as what the warranty covers and what services you can expect from them.
  • Solar Panel Brands: Homeowners will have different preferences for panels depending on their roof configurations and energy needs. While there are many options for which kind of solar panel you can get, not every company will have access to the exact one you may want or need, so make sure you take a look at their list of options before making your decision.
  • Warranty: Companies typically offer different types of warranties that provide different kinds of coverage. A 25-year, all-inclusive warranty is the gold standard.
