Benefits of Solar Energy

Solar energy comes with multiple benefits. Here are some highlights.

  • Lower utility costs: Generating some or all of your own energy will cut power costs long-term. Plus, some states provide net metering programs that make it possible for you to sell your unused energy back to the grid, generating additional credits toward your energy bill.
  • Reduced carbon footprint: Using clean solar power reduces your dependence on conventional, less environmentally-friendly sources.
  • Better energy independence: Adding a solar battery storage system lets you have reliable energy during grid outages and storms.

How To Choose the Best Solar Company in Nashua

The more comprehensive your company investigation is, the better your solar system will ultimately function. Make your choice based on the following vital factors.

Licensing and Training

A master electrician must be present to supervise solar PV installations in New Hampshire. However, solar thermal installers need not be licensed plumbers unless a locality requires it. Solar installers can also obtain certificates from trade groups and standards organizations. The most respected ones in the industry come from the NABCEP. Most company websites will prominently display earned credentials, but you should also ask your estimator for more information.

Cost of Solar Panels in Nashua

Different solar panel types look and perform differently. Monocrystalline panels offer the best energy production but cost more than other options and generally have the highest quality. Polycrystalline panels produce less power, but start at a more budget-friendly price point. Thin-film panels work well for small projects like RVs and sheds, but they're not ideal for larger installations due to their low performance.

Additional system add-ons, such as electric vehicle (EV) chargers and battery storage, will increase your overall installation costs. However, they might make your solar system more efficient and convenient to use. Not every solar provider includes these optional components, so look for a company that sells them if it's a priority for you.

Most Nashua homeowners choose solar systems designed for five kilowatts (kW) of electrical capacity. These systems cost about $21,100 to set up, considering both parts and installation. You can see more specific solar cost information in the table.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,181
Solar Polycrystalline$922
Thin-Film$539
Solar Battery$756
Solar Home EV Charger$2,835

Financing Solar Energy in Nashua

Choosing the right financing option will influence your overall solar system cost and potential savings. Common payment options include power purchase agreements, loans, cash payments, and leases. Though it requires a large up-front payment, cash is the most cost-effective choice because it qualifies you for solar incentives and doesn't accrue interest. Solar loans are the next best option. As with a home or auto loan, you'll pay a monthly rate towards system ownership, including interest. You can still apply for cost-saving solar incentives, and depending on your lender, you could put as little as $0 down. Solar leases let you use your panels for a set monthly rate, while PPAs let you pay only for the energy you use, akin to an electric bill. Both options disqualify you for solar incentives and do not provide you system ownership. Solar experts generally don't recommend them, but they might be suitable in some cases. Look for companies that offer several payment plans to find the right fit for your budget.

The table below lists the average payback periods for different capacities of solar systems in Nashua.

You can claim a 26% federal solar tax credit from the IRS for new residential solar systems purchased before 2032. Additionally, utilities and local governments may have their own financing plans and rebates that could reduce your total cost even more.

1 kW2.2 years

Frequently Asked Questions About Solar in Nashua

How much money could I save by going solar in Nashua?

Most Nashua homeowners spend about $1,407 on energy each year. Your costs could drop by $1,009.79 for each kilowatt you generate after you pay off a solar array.

How popular is solar energy in Nashua?

Yes, solar energy is gaining popularity in Nashua. Some homes already use solar power on-site or through utility grids, and they're supported by a state solar economy with 1031 jobs and counting.

Will solar energy systems improve my Nashua home worth?

Yes, new solar systems lead to higher property values according to the National Renewable Energy Laboratory (NREL.) Homeowners could project a $20 property value increase for each dollar they save on energy. Therefore, $600 in energy savings could boost your property value by $12,000.

What can I do to assess my home's solar potential?

To determine your home's solar readiness, nothing substitutes for a comprehensive quote from a local solar installer. However, you can use the PVWatts tool for a simple solar viability estimate based on public data, including panel efficiency, tree cover, local weather and topography, and system size.

How long does the solar panel installation process require?

There's no universal answer for how long a solar project might take. Ultimately, it depends on the permitting and inspection process, system size, the necessary prework, local weather, and panel style. Most homeowners can be solar-ready within a few months from their initial estimate visit.

What is the average payback period for Nashua solar panels?

The average payback period for a solar loan in Nashua is 14.6 years. By paying off extra principal each month, you can shorten the payback period and own your system faster.

How are a solar lease and PPA different?

Choosing a leasing option means your solar installer will handle panel maintenance while you make fixed monthly payments. Power Purchase Agreements differ slightly because you pay based on the electricity you produce.

You don't own the panels with either option, though you can choose to opt out of the contract for a fee.

How are traditional solar loans and PPAs different?

A power purchase agreement (PPA) is a contract between you and your installer. They install, own, and maintain the panels, and you buy the generated electricity from them for 10–25 years. There will usually be options to buy out early to own your system and extend the agreement.

In contrast, solar loans can come from the government, local banks, installer and specialty lenders. You'll need to pass a credit check to qualify for most of them. While the upfront costs are larger, and you'll be responsible for maintenance, you'll also have total ownership and can apply for many more financial rewards.
