Factors that Affect Solar Panel Costs in Dennis

Though the average cost of a solar system in Dennis is $8,479, your actual cost may be higher or lower than that. There are quite a few factors that can have a significant impact on the cost of a solar panel installation. Below are some of the more important things to take into consideration.

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, you can expect your total to increase by about $2,940. Some solar brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer better efficiency. In a city like Dennis, where sunlight is relatively abundant, efficiency can quickly pay off. Also, if you have a small roof or you don't have a lot of space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

Solar panels can save you money on energy bills over many years, but they can also be a big investment. That's why many Dennis homeowners decide to finance their solar panel systems to offset upfront costs. You'll have to consider the long-term cost of loans, including the total 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 more than the principal cost. Making a larger down payment or getting a solar loan with a low APR could reduce your costs considerably.

Solar Panel Installation Company

The final major cost factor you should keep in mind is the installer you choose. Given the booming popularity of renewable energy solutions in Dennis, you'll have lots of options to choose from, but each comes at different price points for labor and equipment. Additionally, some companies in Dennis are more knowledgeable about local solar incentives and can help you make good use of additional rebates or tax exemptions. Though, they may charge more for walking you through the whole process. Even if they cost more upfront, they could end up saving you more money in the long run.

How to Save on Solar Panels

The solar panel 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, including:

  • Installation Process: When making the switch to solar energy, it's crucial to keep an open line of communication with your solar installer. Confirm that you understand how the installation process works and the project completion timeline.
  • Reputation: Solar installers that have great reviews from their customers and that have been in business for many years most likely provide good-quality solar panel installation and expertise.
  • Solar Panel Brands: Not all solar installers carry the same brands of solar panels, so the brand and type of panel you want can play a big role in the company you opt for.
  • Contract: Before you sign a contract with a solar installer, be sure to read it through fully so you understand the terms. Also, ask questions if you're not sure about some of the terms, such as what the warranty covers and if there are any guarantees about energy production.

EcoWatch's Dennis, MA Solar Cost FAQs

How much does it cost to install solar panels in Dennis?

The average cost of solar panels in Dennis is about $14,700 for a 5-kW system and $29,400 for a 10-kW system before the ITC, but the real cost will depend on certain factors like the kind of solar panels you want, what size system you need and how much energy you consume.

Is it better to lease or buy solar panels in Dennis?

Leasing solar panels can be an option if you are unable to pay upfront or get a solar loan, but since you don't own the system, you don't have access to many solar incentives. Also your home 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.

Is it worth going solar in Dennis?

Whether or not solar panels are worth it depends on some different factors like local electricity rates and the amount of direct sunlight your roof gets.

How long do solar panels last in Dennis?

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 level of energy production.
