Factors that Affect Solar Panel Costs in Hanover

Cost is usually one of the most important factors for homeowners considering investing in solar. There are a few major factors that determine your overall cost in Hanover: 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 size of the solar panel system you need for your household, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, your total will most likely increase by around $4,220. The brand and kind of equipment you choose for your solar system can raise or lower the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these often come at a higher price than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have limited roof space or just want maximum energy production, you can expect a higher equipment cost, but this can typically lead to greater savings over time. Also, if you want add-ons like an electric vehicle charger or solar batteries, this will also raise the cost.

Solar Financing Terms

Most solar companies in Hanover provide solar loans, which reduce the initial cost of installing solar.When trying to figure out your overall cost, you should also calculate the interest you’ll pay if you decide on a solar loan. Also, paying more on your down payment can reduce the total interest paid over time.

Solar Panel Installation Company

The final significant cost factor you should keep in mind is the installer you choose. Given the growing popularity of renewable energy solutions in Hanover, you’ll have many options to choose from, but each comes at varying price points for labor and equipment.Some companies only sell high-efficiency and high-priced 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 find a company that has the products, warranties and services you want and also is within your budget.

How to Save on Solar Panels

Since the model of solar panels and the installer you choose has an impact on 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: If you’re concerned about the durability of your solar panel system, checking if your installer offers a 25-year, all-inclusive warranty can give you some peace of mind.
  • Installation Process: Get detailed information from your solar installer about the installation process and what to expect, including when the site survey will be completed and what the project timeline is.
  • Reputation: Solar panel companies that have great reviews from their customers and that have been operating for many years most likely offer good-quality solar panel installation and expertise.
  • Contract: Although reading through a contract can be tedious, it’s important to do it carefully so you can be sure you understand what services your solar company will provide and the terms of the warranty.

EcoWatch's Hanover, NH Solar Cost FAQs

How much does it cost to install solar panels in Hanover?

This is a tough question to answer exactly, because the cost depends on a variety of factors. Generally speaking, it costs about $21,100 for a 5-kW system and $42,200 for a 10-kW system after the ITC is applied. You can expect to pay more if you want other solar equipment or higher quality panels, or if you have above-average energy needs. On the other hand, you can spend less if you want a smaller solar panel system or cheaper solar panels.

Should I lease or buy solar panels in Hanover?

Leasing solar panels can be an option if you can’t afford to pay upfront or get a solar loan, but since you don’t own the system, you don’t have access to many solar incentives. Also your property value won’t increase, so you’ll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most bang for your buck from going solar.

Is it worth going solar in Hanover?

Whether or not solar panels are worth it depends on a variety of factors like local electricity rates and the amount of direct sunlight your roof gets.

What solar power system size is right for my home?

The exact number of solar panels you need depends on your household energy consumption and the average daily sunlight your roof gets. You can take a look at your energy bills for the past year to get an idea of the solar system size you'll need. The average household has to install between 20 and 35 panels to account for their typical energy usage.
