The Cost and Benefits of Solar in Dartmouth

For many readers, the decision of which solar installer to choose depends on pricing. A few main factors that dictate the cost of installing solar panels on your home and how much money you could save over time are:

  • System size and type: Some models are more costly than others, so the one you choose can raise or lower your initial investment. Plus, the more solar panels you need, the more it'll cost.
  • Incentives: The federal solar investment tax credit, which everyone qualifies for, lets you deduct 26% of the cost of your solar system installation from your taxes. In addition, not including incentives, you can save about $23,000 over 20 years on your energy bills.
  • Your power bills: This will determine your savings. In Dartmouth, the average resident can save about $1,000 a year on their electricity bills.
  • Electricity consumption: The average household in Dartmouth doesn't use much energy, and as a result may not see as many savings on their power bills.

There are several wonderful benefits of solar in spite of the upfront cost of installation. It can help the Earth and your finances. Plus, it can boost the value of your home, leading to even more benefits if you choose to sell your home later.

EcoWatch's Dartmouth, MA Solar Company Rankings FAQs

Which solar company is the best in Dartmouth?

In Dartmouth, Alternative Energy Store, Inc. is the most reputable local solar company. Our team of experts rates it 5.00 stars, so it's a great choice if you're planning to add solar panels to your home.

What are a few of the major pros and cons of going solar?

The greatest advantages of solar power are that it can decrease or, for some, 100% cut your electricity bills, improve your home's value and lower your carbon footprint. The greatest disadvantages are that solar panels can be pricey to install, you may not save as much if you don't use a lot of electricity and it doesn't work for all roof types and locations.

How long does it take to see a return on your investment after buying solar panels?

The average payback period for solar panel installation is about 9.0 years, but the exact period is influenced by local electricity costs, incentives and net metering programs.

How long do solar panels last?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of. What this means is their energy production will have decreased significantly after that point. You can choose to replace them after having them for that long or you can continue to use them at a lower efficiency after that time.
