Factors that Affect Solar Panel Costs in Thornwood

Cost is usually one of the most important factors for homeowners who are considering investing in solar. There are a few key factors that determine your overall cost in Thornwood: solar equipment and system size, financing options and the solar installation company you choose. We'll discuss each of these briefly below.

Solar Equipment

The cost of solar panels varies by thousands of dollars due to a variety of factors. One of the notable factors is the system size, which is measured in kilowatts (kW). Solar power systems with greater efficiency or power generation require better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $2,950. There are several different solar panel brands and the one you pick also changes the cost. In general, the brands that have better efficiency tend to also cost more. Plus, the type of equipment you choose can affect your total cost. If you only need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

Solar panels can save you money on power bills over time, but they can also be a big investment. That's why many Thornwood homeowners choose to finance their solar panel systems to make going solar more affordable. You'll have to consider the long-term cost of loans, including the total interest you'll pay over the length of the loan. If you're only able to get a high-interest loan, then your total can be hundreds or even thousands of dollars more than the principal cost. Making a larger down payment or getting a solar loan with a low interest rate could reduce your costs considerably.

Solar Panel Installation Company

Finally, the company you opt for to install your solar system can play a role in determining how much it costs. Thornwood's solar companies all have different labor costs and add varying upcharges to equipment. Companies that only sell high-quality, high-efficiency and high-price 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 provides the products, warranties and services you want and also is within your budget.

How to Save on Solar Panels

The solar company you choose will influence not only your total 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, such as:

  • Reputation: Your solar installer should have a sound reputation as a company and have proven expertise in the field. Two ways to check this are to look for whether a company has technicians that hold a certification from the North American Board of Certified Energy Practitioners (NABCEP) and if it has good reviews from past customers.
  • Warranty: Warranties that cover defective panels and repairs over a long period of time such as 25 years are the best you can get in the business, and offering such a warranty is one sign of a quality company.
  • Contract: When looking over your solar company'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 component breaking or if the company goes out of business.
  • Solar Panel Brands: Homeowners will have different preferences for panels depending on their locations and energy needs. While there are many options for which type 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 peruse their list of offerings before deciding.
