Factors that Affect Solar Panel Costs in Nashua

Though the average cost of a solar system in Nashua is $10,083, your actual cost may be higher or lower than that. There are quite a few factors that can have a major impact on the cost of a solar system installation. Below are some of the more important things to keep in mind.

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 around $2,910 per kilowatt in Nashua. The brand and kind of equipment you get for your solar system can raise or lower the price quite significantly. If you prefer a brand name like Tesla or SunPower, these often have a higher price tag than other brands. Efficiency also matters. Whether you're opting for high efficiency because you have a small roof or just want maximum energy production, you can expect a higher equipment cost, but this can typically lead to greater savings over time. Also, if you want add-ons like an electric vehicle charger or solar batteries, this will also raise the cost.

Solar Financing Terms

Many homeowners find the average cost of solar in Nashua to be prohibitively steep, even if the investment pays off over time. Thankfully, almost every solar installer in the area provides access to financing options. Solar loans substantially decrease upfront costs in most cases, but they also lead to a higher cost over time because of interest. Though solar loans make adopting solar energy more accessible for Nashua homeowners, they can also increase the total you pay for your system, depending on your interest rate and how long you take to pay off the loan. If you put down a larger down payment, though, you can cut back on how much interest you have to pay.

Solar Panel Installation Company

A final consideration when trying to figure out the cost of solar for your home or business in Nashua is the company you get to install your PV system. Similar to choosing a company to build a deck or pool, for example, you'll have no shortage of solar installers that offer a range of services for different budgets. Larger national companies typically have lower costs, but some local companies keep up with them by offering sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or additional services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels

There are a lot of solar installers to choose from, all of which offer different warranties, solar panel brands and price points. To help you find the right company for you, here are some tips to keep in mind:

  • Solar Panel Brands: Not all solar companies have the same brands of solar panels, so the brand and type of panel you want can play a substantial role in the company you choose.
  • Reputation: Solar companies that have great reviews from their customers and that have been in business for many years likely offer high-quality solar panel installation and expertise.
  • Installation Process: When going solar, it's necessary to maintain an open line of communication with your solar panel company. See to it that you understand how the installation process will go and the project timeline.
  • Contract: Review the contract terms carefully to make sure you understand the cost breakdown, project completion timeline incentives and warranties.
