Factors that Affect Solar Panel Costs in Derry

For many Derry homeowners, the decision to adopt solar energy comes down to cost. However, the range of solar installation costs can be quite wide in Derry, with typical prices between $20,000 to $40,000. There are a number of factors that considerably influence the price you'll pay, which we'll go over below.

Solar Equipment

Solar system size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of installing solar panels. That's why it's crucial to accurately assess the size of the solar energy system needed for your home by figuring out your typical energy use. The brand of solar panels and equipment you want is another factor that will considerably 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 make decisions about 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 falls within your budget.

Solar Financing Terms

Most solar installers in Derry offer solar loans, which reduce your upfront costs of installing solar. However, the interest on solar loans also adds to your overall costs, so it's important to keep that in mind as well. You can always bring down the total you pay in interest and in some cases even your APR by making a larger down payment.

Solar Panel Installation Company

The solar company you choose to handle your switch to solar energy can have an effect on your total costs. There are about 3 solar installation companies operating throughout Derry, and each can charge varying amounts for labor and equipment. Additionally, some companies in Derry have more knowledge about local solar incentives and can help you take advantage of additional rebates or tax exemptions. However, they may charge more for that service. Even if they cost more upfront, they could end up saving you more money in the long run.

How to Save on Solar Panels

The solar installer you opt for will influence not only your overall costs, but also the types of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are some important things you should keep in mind, such as:

  • Contract: It's important to look over your solar installer's contract fully to understand what services they will provide, what the warranty covers and what you can expect about the installation process.
  • Warranty: If you care about the longevity of your solar panels, checking if your installer offers a 25-year, all-inclusive warranty can help put you at ease.
  • Solar Panel Brands: Not all solar companies have the same brands of solar panels, so the brand and type of panel you want can play a large role in the company you choose.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for sustainable energy professionals. If your solar panel installer is NABCEP-certified, it likely has a solid reputation and is qualified to do the job well. Another way you can verify your installer's reputation is by reading reviews.

How often do you have to replace solar panels?
