Factors that Affect Solar Panel Costs in Durham

Even though the average cost of solar panels in Durham is $10,002, your actual 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 take into consideration.

Solar Equipment

The size of the system you need is one of the largest factors that affects the overall cost of installing solar panels. For that reason, it's a priority to accurately assess the size of the solar energy system needed for your home by figuring out your energy needs. There are several different solar panel brands and the one you pick also affects the cost. Generally speaking, the brands that have better efficiency tend to also cost more. In addition, the type of equipment you're looking to install can affect your total cost. If you just need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

Many homeowners find the average cost of solar in Durham to be prohibitively steep, even if the investment pays off over time. Thankfully, almost every solar company in the area provides access to financing options. Solar loans substantially decrease upfront costs for most homeowners, but they also lead to paying more over time because of interest. Although solar loans make going solar more accessible for Durham homeowners, they can also raise the total you pay for your system, depending on your interest rate. If you make a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

The solar installer you choose will play a role in your total cost to go solar. Different companies will bill different amounts for the equipment and labor. Additionally, some companies in Durham have more knowledge about local solar incentives and can help you make good use of additional rebates or tax exemptions. Though, they may charge more for walking you through the whole process. 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 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 select the right ones for you. Here are some tips to keep in mind to help with your decision:

  • Warranty: A quality company rises above other companies by providing the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
  • Solar Panel Brands: Different companies will offer different brands and models of panels. If you want a specific brand, make sure the solar installer you're considering has it.
  • Installation Process: When making the switch to solar power, it's crucial to keep an open line of communication with your solar panel installer. Confirm that you understand how the installation process works and the completion timeline.
  • Contract: Even though reading through a contract can take a lot of time, it's important to do it carefully so you can be sure you understand how much the equipment and services will cost and the terms of the warranty.

EcoWatch's Durham, NH Solar Cost FAQs

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

The average cost of solar panels in Durham is about $14,550 for a 5-kW system and $29,100 for a 10-kW system before the ITC, but the real cost will depend on things such as the model of solar panels you want, what size system you need and how much energy you consume.

Should I lease or buy solar panels in Durham?

Leasing solar panels can be an option if you can't afford to pay upfront or secure a solar loan, but since you don't own the system, you can't take advantage of 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.

Does Durham have a net metering program?

Most states offer net metering programs of some kind. Through these, you can either get paid for the extra power your system produces or or receive credits to put toward future energy bills. Currently there are just three states that don't have any net metering laws: Alabama, Tennessee and South Dakota.

What solar power system size is right for my home?

The exact number of solar panels you need depends on your household energy needs and the amount of sunlight your roof gets. You can 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 get between 20 and 35 panels to account for their typical energy usage.
