Factors that Affect Solar Panel Costs in Peterborough
Cost is typically one of the most important factors for homeowners who want to invest in solar. There are a few key factors that will push your cost above or below the average in Peterborough: solar equipment and system size, financing options and the solar installation company you choose. We’ll go over each of these briefly below.
Solar Equipment
One of the most significant factors to consider when it comes to the cost of adopting solar energy is the size of the solar system, which is measured in kilowatts (kW). The more power your household consumes, the larger your system will likely need to be. You can expect to spend about $4,220 per kilowatt in Peterborough.The kind of solar panels and equipment you get is another factor that will substantially influence costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to cost more. Further, solar equipment goes beyond just the solar panels themselves. You’ll also need to think about the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when researching a solar system that falls within your budget.
Solar Financing Terms
If paying for solar panels out of pocket is out of reach, solar loans are a popular option because they reduce your upfront costs and let you pay for your system over a term of, on average, between five and seven years.It’s wise to factor the interest you’ll pay in your final cost estimate. If you can afford to pay a larger down payment, you can reduce your total costs and how long it’ll take to pay back the loan.
Solar Panel Installation Company
A final factor to consider when trying to estimate the cost of solar for your home or business in Peterborough is the company you hire to install your solar panel system. Similar to choosing a company to build a deck or pool, for example, there’s no shortage of solar installers that provide a range of services at different costs.Larger national companies generally have lower costs, but some local companies keep up with them by promoting sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or add-on services like electric car charger installation, they might be cheaper overall.

- Warranty: If you care about the longevity of your solar panels, making sure your company offers a 25-year, all-inclusive warranty can help put you at ease.
- Installation Process: Homeowners should understand how exactly the installation process will be carried out, as well as important factors like the completion timeline.
- Contract: It’s important to read your solar installer’s contract fully to understand what services they will provide, what the warranty covers and what you can expect about the project timeline.
- Reputation: Your solar installer should have a solid reputation as a company and have proven expertise in the field.

EcoWatch's Peterborough, NH Solar Cost FAQs
How much does it cost to install solar panels in Peterborough?
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 extra solar equipment or higher quality panels, or if you have above-average energy needs. On the other hand, you can spend less if you choose a smaller solar panel system or less efficient solar panels.
Is cost the most important consideration when buying solar panels?
The initial cost is a crucial factor to consider, but whether it’s the most important for you depends on why you decided to go solar. In areas where rooftop space is limited, efficiency can be more important than the cost. Other factors that are important to take into account are the quality and durability of your solar panels.
Do solar panels increase your home value?
Solar panels can increase the value of your home significantly as long as you buy or finance your panels and don’t opt for a solar lease or power purchase agreement (PPA). According to research done by Zillow, the average home value increases by about 4.1% with a solar installation."
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 needs and how much sunlight your home gets. For a general estimate, however, since each panel can typically produce about 250 to 400 watt-hours per hour, the average house will need 20 to 35 panels.
