Factors that Affect Solar Panel Costs in Douglas

While the average cost of a solar system in Douglas is $12,726, your final cost may be higher or lower than that. There are many factors that can have a major impact on the cost of a solar system installation. Below are some of the more important things to consider.

Solar Equipment

The size of the solar energy system you need for your home, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, your total will most likely increase by nearly $4,060. There are several different solar panel brands and the one you choose also affects the cost. Generally, the brands that have better efficiency tend to also be more expensive. Additionally, the type of equipment you’re looking to install can affect your total cost. If you just need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

For some homeowners, paying for a solar system out of pocket can be difficult. Solar loans are offered by most installers in Douglas, which can lower, or in some cases eliminate, your upfront costs to make solar more affordable.You’ll have to consider the long-term cost of loans, including the amount of 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 above the equipment and labor cost. Making a larger down payment or securing a solar loan with a low interest rate could reduce your costs considerably.

Solar Panel Installation Company

The remaining significant cost factor you should take into consideration is the installer you choose. Given the booming popularity of sustainable energy solutions in Douglas, you’ll have lots of options to choose from, but each comes at varying price points for labor and equipment.You may see national solar installers that have lower prices due to their bigger brand name and access to bulk equipment prices, or you might see small, local installation companies offering deals or specials to compete with those larger companies.

How to Save on Solar Panels

There are numerous companies available in Douglas, and some homeowners feel overwhelmed considering their options. Picking the right company for you can be challenging, so here are some tips to help you decide:

  • Contract: Though reading through a contract can take a lot of time, it’s important to do it thoroughly so you can make sure you understand what services your solar company will provide and how part repairs and replacements will be handled.
  • Reputation: Well-established companies likely have a solid reputation. This is important because it ensures that it will not only see your solar installation through, but will also provide adequate aftercare and customer support, such as part repairs and replacements.
  • Warranty: A high-quality company stands out from other companies by providing the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
  • Installation Process: Homeowners should understand how exactly the installation process will be carried out, as well as important factors like the project completion timeline.
