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 biggest one is your system size, and other factors include the equipment you choose, financing options and the solar company you choose.

Solar Equipment

Solar system size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of installing solar panels. Because of that, it's important to accurately ascertain the size of the solar energy system needed for your home by figuring out your energy needs. There are several different solar panel brands and the one you choose also affects the cost. In general, the brands that are more efficient tend to also cost more. Additionally, the type of equipment you want to install can affect your total cost. If you only need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

For some homeowners, paying for solar out of pocket can be challenging. Solar loans are provided by most installers in Dartmouth, which can lower, or in some cases completely 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 in some cases even your APR by making a larger down payment.

Solar Panel Installation Company

The remaining significant cost factor you should take into consideration is the installer you choose. Given the booming popularity of clean energy solutions in Dartmouth, you'll have plenty of options to choose from, but each comes at various price points for labor and equipment. You may notice national solar installers that have lower prices due to their bigger brand name and access to bulk equipment prices, or you might see small, local installation companies offering deals or specials to compete with those larger companies.

How to Save on Solar Panels

The solar company you go with will impact not only your overall costs, but also the types of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are several important things you should keep in mind, such as:

  • Warranty: Each company may offer different types of warranties that provide different kinds of coverage. A 25-year, all-inclusive warranty is the gold standard.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for sustainable energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a solid reputation and is qualified to do the job well. Another way you can check your installer's reputation is by reading reviews.
  • Contract: Review the contract terms closely to make sure you understand the cost breakdown, completion timeline rebates and warranties.
  • Solar Panel Brands: Not all solar companies carry the same brands of solar panels, so the brand and type of panel you want can play a significant role in the company you hire.

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 variety of factors. Generally speaking, it costs about $14,700 for a 5-kW system and $29,400 for a 10-kW system after the ITC is applied. You can expect to pay more if you want other solar equipment or more efficient panels, or if you have above-average energy consumption. On the other hand, you can spend less if you choose 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 appealing choice, as it commonly comes with low or $0 upfront payments. The downside is that you won't be able to save as much. If you lease, you don't own the system, so you can't claim any tax rebates and credits and your home value won't increase. Buying solar panels is a better option if you want to maximize your savings.

Can solar panels significantly reduce my energy bills?

It is possible to erase your electricity bills with solar panels, but for most homeowners in Dartmouth, that will require at least a 10-kW system. Not all homes can accommodate that size system, so you'll want to check with a local solar installer to see how many panels can fit on your roof.

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 decreases by about 0.8% each year. You can choose to replace them sooner if you want to maintain a higher amount of energy production.
