Factors that Affect Solar Panel Costs in Plymouth

For many Plymouth homeowners, the decision to adopt solar energy rests on cost. However, the range of solar installation costs can be quite wide in Plymouth, with typical prices between $20,000 to $40,000. There are a few factors that significantly influence the price you’ll pay, which we'll go over below.

Solar Equipment

When it comes to estimating the cost of solar panels in Plymouth, one of the most important factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are mainly based on your home’s energy consumption, which you can determine by looking at past power bills. Your total cost can increase by about $4,220 for each additional kilowatt you need.There are several different solar panel brands and the one you pick also changes the cost. In many cases, the brands that offer higher efficiency tend to also be more expensive. In addition, the type of equipment you’re looking to get can affect your total cost. If you just need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

If paying for a solar system in cash is too expensive, solar loans are a popular option because they lower your upfront costs and allow you to pay for your system over five to seven years on average.You’ll have to consider the long-term cost of loans, including the amount of interest you’ll pay over the length of the loan. If you can only get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or finding a solar loan with a low APR could reduce your costs significantly.

Solar Panel Installation Company

A final consideration when trying to evaluate the cost of solar for your home or business in Plymouth is the company you hire to install your solar panel system. Similar to choosing a company to install new cabinets, for example, you’ll have no shortage of solar installers that offer a range of services for different budgets.You may notice national solar installers that have lower prices because of their larger brand name and access to bulk prices, or you might see small, local installation companies offering deals or promotions to compete with those larger companies.

How to Save on Solar Panels

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

  • Contract: Review the contract terms closely to make sure you understand the cost breakdown, project completion timeline rebates and warranties.
  • Reputation: Your solar installer should have a solid 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 satisfied reviews from past customers.
  • Installation Process: Homeowners should understand how exactly the installation process will be carried out, as well as important factors like the project timeline.
  • Solar Panel Brands: Not all solar installers offer the same brands of solar panels, so the brand and type of panel you want can play a large role in the company you opt for.

EcoWatch's Plymouth, NH Solar Cost FAQs

What is the average cost of installing solar panels in Plymouth?

This is a difficult question to answer precisely, because the cost depends on a few different factors. Broadly 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 additional solar equipment or higher quality panels, or if you have above-average energy usage. On the other hand, you can spend less if you want a smaller solar panel system or cheaper solar panels.

What other factors should I consider in addition to cost when buying solar panels?

The initial cost is a very important factor to consider, but whether it’s the most important for you depends on your goals for going solar. In areas where rooftop space is limited, efficiency can trump the cost. Other factors that are important to be mindful of are the quality and durability of your solar panels.

Does Plymouth have a net metering program?

Each state has some kind of net metering programs except Tennessee, South Dakota and Alabama currently. Some states allow you to sell power back to the grid, but others just offer you credit toward your future electricity bills.

What solar power system size is right for my home?

The exact number of solar panels you need depends on your household energy needs and how much sunlight your roof gets. You can look at your energy bills for the past year to get an idea of the solar system size you'll need. The average household has to buy between 20 and 35 panels to cover their typical energy usage.
