Factors that Affect Solar Panel Costs in Keene
There are a number of factors that can influence your solar panel 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
The size of the solar panel 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 better efficiency. In a city like Keene, where sunlight isn’t as abundant, efficiency can quickly pay off. Also, if you have a small roof or you don’t have a lot of space for your panels, higher efficiency options will be more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.
Solar Financing Terms
Most solar companies in Keene provide solar loans, which reduce your upfront costs of installing solar panels.Even though solar loans make going solar more accessible for Keene homeowners, they can also increase the total you pay for your system, depending on your interest rate. If you make a larger down payment, though, you can cut back on how much interest you have to pay.
Solar Panel Installation Company
The remaining significant cost factor you should take into consideration is the installer you choose. Given the growing popularity of renewable energy solutions in Keene, you’ll have a great number of options to choose from, but each comes at varying price points for labor and equipment.Companies that only sell high-quality, high-efficiency and high-price products — 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 choose a company that provides the products, warranties and services you’re looking for and also is within your budget.

How to Save on Solar Panels
The solar panel company you choose will impact not only your overall 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 keep in mind, including:
- Warranty: Warranties that provide coverage for replacement parts and repairs over around 25 years are the gold standard in the business, and offering such a warranty is one mark of a good company.
- Contract: Before signing a contract with a solar installer, make sure you read it through fully so you understand the terms. Also, ask questions if you’re not sure about some of the terms, such as what the warranty covers and if there are any guarantees about energy production.
- Installation Process: Get detailed information from your solar company about the installation process and what to expect, such as when the site survey will be done and what the project timeline is.
- Solar Panel Brands: Each solar panel brand and type has varying levels of quality, durability and energy efficiency. They will come at different prices as well. The company you choose impacts which solar panel brands you have access to.
EcoWatch's Keene, NH Solar Cost FAQs
What is the average cost of installing solar panels in Keene?
This is a hard question to answer exactly, because the cost depends on many 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 other solar equipment or more efficient panels, or if you have higher-than-average energy consumption. On the flip side, you can spend less if you want a smaller solar panel system or less efficient solar panels.
Should I lease or buy solar panels in Keene?
Leasing solar panels can be an option if you can’t pay upfront or get a solar loan, but since you don’t own the system, you can’t take advantage of many solar incentives. Also your home 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.
Can you sell solar power back to the grid in Keene?
Each state has some form of net metering programs except Tennessee, South Dakota and Alabama currently. Some states let you sell power back to the grid, but others just offer you credit toward your future utility bills.
How long do solar panels last in Keene?
Although the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of at that time. What this means is the amount of energy they produce will have decreased significantly after that point. You can opt to replace them once you've had them for that long or you can continue to use them at a lower efficiency.
