Factors that Affect Solar Panel Costs in Nashua
For many Nashua homeowners, the decision to adopt solar energy comes down to cost. However, the range of solar installation costs can be quite wide in Nashua, with typical prices between $20,000 to $40,000. There are numerous factors that considerably influence the price you’ll pay, which we'll go over below.
Solar Equipment
Solar system size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of going solar. That’s why it’s important to accurately gauge the size of the solar energy system needed for your home by figuring out your average energy use.Some solar panel brands — like Maxeon from SunPower — are more costly upfront but also tend to offer higher efficiency. In a city like Nashua, where sunlight isn’t as abundant, efficiency can quickly pay off. Plus, if you have a small roof or you don’t have a lot of 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 financially overwhelming. Solar loans are provided by most installers in Nashua, which can lower, or in some cases totally eliminate, your upfront costs to make solar more accessible.However, the interest on solar loans also adds to your total costs, so it’s important to take that into consideration as well. You can always lower the total you pay in interest and sometimes even your APR by putting more money down.
Solar Panel Installation Company
Finally, the company you opt for to install your solar panels can play a role in determining how much it costs. Nashua’s solar companies all have different labor costs and add varying upcharges to equipment. The size of the company can sometimes play the most considerable role in the installation costs. Larger national companies, like SunPro and Sunrun, often have lower pricing due to greater resources and bulk pricing. Smaller local companies might be more costly, but they can sometimes have better customer service and more customization options, and the occasional sale or discount can bring their pricing lower to compete with bigger names.

How to Save on Solar Panels
Since the brand 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 things to keep in mind to help with your decision:
- Installation Process: Get details 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.
- Reputation: Your solar installer should have a sound reputation as a company and have proven expertise in the field. A couple of ways to check this are to look for whether a company has technicians certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it has positive reviews from past customers.
- Warranty: Each company may offer different kinds of warranties that provide different kinds of coverage. A 25-year, all-inclusive warranty is the gold standard.
- Contract: Review the contract terms carefully to make sure you understand the cost breakdown, project timeline incentives and warranties.
