Factors that Affect Solar Panel Costs in Goffstown

There are a number of factors that can determine your total installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar system.

Solar Equipment

One of the most significant factors to consider when it comes to the cost of going solar is the size of the solar system, which is measured in kilowatts (kW). The more power your household uses, the larger your system will likely need to be. You can expect to pay about $4,220 per kilowatt in Goffstown.There are a lot of different solar panel brands and the one you pick also affects the cost. Typically, 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

Most solar installers in Goffstown have solar loans, which reduce your upfront costs of installing a solar system.You’ll have to consider the long-term cost of financing options, 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 getting a solar loan with a low interest rate could reduce your costs remarkably.

Solar Panel Installation Company

The solar installer you choose to handle your switch to sustainable energy can play a part in your total costs. There are about 3 solar installation companies in Goffstown, and each can charge different amounts for labor and equipment.Additionally, some companies in Goffstown know more about local solar incentives and can help you learn about additional rebates or tax exemptions. However, they may charge more for that service. Even if they cost more upfront, they could help you save more money in the long run.

How to Save on Solar Panels

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

  • 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.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a good reputation and is qualified to install your solar system. Another way you can check your installer’s reputation is by reading reviews.
  • Contract: When reading through your solar company’s contract, ask for clarification about any terms you’re not sure of and make sure you understand what happens in scenarios such as a system part breaking or if the company goes out of business.
  • 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 large role in the company you opt for.
