Factors that Affect Solar Panel Costs in Littleton

There are many factors that can determine your installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that performs the installation.

Solar Equipment

The size of the solar energy system you need to offset your energy usage, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, your total will most likely increase by nearly $4,220. Some solar panel brands — like Maxeon from SunPower — are more costly upfront but also tend to offer higher efficiency. In a city like Littleton, where sunlight isn’t as abundant, efficiency can quickly pay off. Also, if you have a small roof or limited space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

For some homeowners, paying for solar panels out of pocket can be challenging. Solar loans are available from most installers in Littleton, which can lower, or in some cases completely eliminate, your upfront costs to make solar more accessible.However, the interest on solar loans also increases your total costs, so it’s crucial to consider that as well. You can always reduce the total you pay in interest and sometimes even your APR by making a larger down payment.

Solar Panel Installation Company

A final factor to keep in mind when trying to figure out the cost of solar for your home or business in Littleton is the company you get to install your PV system. As with choosing a company to install new cabinets, for instance, there are plenty of solar installers that provide a range of services for different budgets.Companies that only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come at a higher cost. 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

The solar installer you opt for will be a major factor in determining 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 take into account, including:

  • Solar Panel Brands: Homeowners will have different preferences for panels based on their roof configurations and energy needs. Although there are many options for which model of solar panel you can get, not every company will have the exact one you may want or need, so make sure you peruse their list of offerings before deciding.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established 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 do the job well. Another way you can check your installer’s reputation is by reading reviews.
  • Contract: Before you sign a contract with a solar company, be sure to read it through completely so you understand the terms. Also, ask questions if you’re not sure about some of the terms, such as what to do if a component breaks or malfunctions and if there are any guarantees about energy production.
  • Warranty: A quality company stands out from other companies by offering the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.

EcoWatch's Littleton, NH Solar Cost FAQs

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

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. It will cost more if you want additional solar equipment or higher quality panels, or if you have above-average energy usage. On the other hand, you can spend less if you want a smaller solar panel system or less efficient solar panels.

Can you get solar panels for free in Littleton?

Solar panels aren’t free in Littleton, but there are some options that can make getting them more viable, such as leasing solar panels or getting a solar loan. There may also be local programs or incentives that can help lower the cost.

Can solar panels completely eradicate my energy bills?

It is possible to erase your electricity bills with solar panels, but for most homeowners throughout Littleton, that will require at least a 10-kW system. Not all homes can accommodate that size system, so you’ll want to check with a local solar installer to see how many panels can fit on your roof.

What solar power system size is right for my home?

To figure out how many solar panels you need, you need to know how much energy your home uses and how much sunlight your home gets. For a general estimate, however, since each panel can generally produce about 250 to 400 watt-hours per hour, the average house will need 20 to 35 panels.
