Factors that Affect Solar Panel Costs in Dartmouth

The cost of installing a solar system in Dartmouth can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The largest one is the size of the system your household needs, and other factors include the equipment you choose, financing options and the solar company you choose.

Solar Equipment

The size of the solar panel system you need, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, your total will most likely increase by around $4,060. The kind of solar panels and equipment you want is another factor that will significantly impact costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to be more pricey. Furthermore, solar equipment is more than 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 looking for a solar system that’s in your budget.

Solar Financing Terms

If paying for solar panels out of pocket is difficult, solar loans are an affordable option because they cut back your upfront costs and allow you to pay for your system over a term of, on average, between five and seven years.You’ll have to consider the long-term cost of financing options, including the amount of interest you’ll pay over the length of the loan. If you’re only able to 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 securing a solar loan with a low interest rate could reduce your costs remarkably.

Solar Panel Installation Company

Finally, the company you choose to install your solar system can affect the cost. Dartmouth’s solar companies all have different labor costs and add varying upcharges to equipment. 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 extra services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels

There are a large number of companies available in Dartmouth, and some homeowners feel overwhelmed considering their options. Selecting the right company for you can be tough, so here are some tips to help you decide:

  • Installation Process: When going solar, it’s necessary to keep an open line of communication with your solar installer. Make sure you understand how the installation process will go and the project timeline.
  • Contract: Although reading through a contract can take a lot of time, it’s important to do it carefully so you can be sure you understand what services your solar company will provide and how part repairs and replacements will be handled.
  • Warranty: Warranties that provide coverage for defective panels and repairs over around 25 years are the gold standard in the business, and offering such a warranty is one mark of a good company.
  • Solar Panel Brands: The brand of solar panel you’d like to get plays a role in which company you should opt for, since different companies have different panels.

EcoWatch's Dartmouth, MA Solar Cost FAQs

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

This is a hard question to answer exactly, because the cost depends on a few different factors. Generally speaking, it costs about $20,300 for a 5-kW system and $40,600 for a 10-kW system after the ITC is applied. It will cost more if you want additional solar equipment or more efficient panels, or if you have above-average energy usage. Conversely, you can spend less if you want a smaller solar panel system or less expensive solar panels.

Should I lease or buy solar panels in Dartmouth?

Leasing solar panels can be an option if you can’t pay upfront or secure a solar loan, but since you don’t own the system, you can’t take advantage of many solar incentives. Also your property value won’t increase, so you’ll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most financial benefits from going solar.

Can you sell solar power back to the grid in Dartmouth?

Most states have net metering programs of some kind. Through these, you can either get paid for the extra power your system generates or or receive credits to put toward future utility bills. Currently there are just three states that don’t have any net metering laws: Alabama, Tennessee and South Dakota.

How often do you have to replace solar panels?

On average, the lifespan of solar panels is about 25 to 30 years. Some even last up to 50 years, but their efficiency goes down by about 0.8% each year. You can choose to replace them sooner if you want to maintain a higher level of energy production.
