Factors that Affect Solar Panel Costs in Derry

Although the average cost of a solar system in Derry is $9,818, your final cost may differ. There are many factors that can have a significant impact on the cost of a solar system installation. Below are some of the more important things to take into consideration.

Solar Equipment

One of the most significant 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 electricity your household uses, the larger your system will likely need to be. You can expect to pay around $2,910 per kilowatt in Derry. There are a lot of different solar panel brands and the one you pick also changes the cost. In general, the brands that have better efficiency tend to also be more expensive. Plus, the type of equipment you're looking to get 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

If paying for a solar system in cash is too expensive, solar loans are an affordable option because they decrease your upfront costs and let you pay for your system over a term of, on average, between five and seven years. When figuring out your overall cost, you should also calculate the interest you'll pay if you opt for a solar loan. Also, paying more upfront can reduce the total interest paid over time.

Solar Panel Installation Company

Finally, the company you opt for to install your solar panel system can play a part in determining your pricing. Derry's solar companies all have different labor costs and add varying upcharges to equipment. Additionally, some companies in Derry are more knowledgeable about local solar incentives and can help you learn about additional rebates or tax exemptions. Though, 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 panel company you go with will affect not only your total costs, but also the types of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are a few important things you should consider, including:

  • Reputation: Solar panel companies that have great reviews from their customers and that have been in business for many years likely offer high-quality solar panel installation and expertise.
  • Solar Panel Brands: Not all solar companies offer the same brands of solar panels, so the brand and type of panel you want can play a substantial role in the company you opt for.
  • Contract: Although reading through a contract can be tedious, it's important to do it fully so you can make sure you understand how much the equipment and services will cost and how part repairs and replacements will be handled.
  • Installation Process: One of the most important things to understand when going solar is the installation process itself. Be sure to align on any details you need to know with your solar installer, such as what permits you should secure and how long the project will take.
