Factors that Affect Solar Panel Costs in South Dennis

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

Solar Equipment

One of the most significant factors to consider when it comes to the cost of adopting solar energy is the size of the solar system, which is measured in kilowatts (kW). The more electricity your household consumes, the larger your system will likely need to be. You can expect to spend about $2,940 per kilowatt in South Dennis. The solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you opt for the most efficient solar panel brands, you'll end up paying more upfront than if you opted for the most affordable panels. However, more efficient panels could save you more in the long run on your electric bills. Additionally, extra products, like solar batteries, can bump up your total well above the South Dennis average.

Solar Financing Terms

If paying for a solar system out of pocket is difficult, solar loans are an affordable choice because they lower your upfront costs and let you pay for your system over five to seven years on average. However, the interest on solar loans also increases your total costs, so it's vital to take that into consideration as well. You can always lower the total you pay in interest and sometimes even your APR by making a larger down payment.

Solar Panel Installation Company

The solar panel installer you pick will impact your total cost to adopt solar energy. Different companies will charge different amounts for the equipment and labor. Companies that only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally cost more. It's best to do some research and decide on the company that provides the products, warranties and services you're looking for and also is within your budget.

How to Save on Solar Panels

The company that does your solar system installation will affect the warranties and brands you have access to, and it will also have an impact on your total cost. Because selecting a company can be a tough decision, we have some tips to help you, such as:

  • Contract: Although reading through a contract can be tedious, it's important to do it thoroughly so you can be sure you understand what services your solar company will provide and the terms of the warranty.
  • Solar Panel Brands: The model of solar panel you want plays a part in which installer you should choose, since different companies offer different panels.
  • Installation Process: Get detailed information from your solar company about the installation process and what to expect, such as when the site survey will be completed and how long it will take.
  • 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 install your solar system. Another way you can research your installer's reputation is by reading reviews.

EcoWatch's South Dennis, MA Solar Cost FAQs

What is the average cost of installing solar panels in South Dennis?

This is a tough question to answer exactly, because the cost depends on a variety of factors. Broadly speaking, it costs about $14,700 for a 5-kW system and $29,400 for a 10-kW system after the ITC is applied. It will cost more if you want extra solar equipment or more efficient panels, or if you have above-average energy consumption. Conversely, you can spend less if you opt for a smaller solar panel system or less efficient solar panels.

What other factors should I consider apart from cost when buying solar panels?

Cost is definitely one of the most important things to bear in mind when buying solar panels, but other important factors include efficiency, durability, and quality.

How much can I save on power bills after installing solar panels?

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

How many solar panels do I need to power my home?

To figure out what solar panel system size you need, you need to know how much energy your home uses and how much sunlight your home gets. For a general estimate, however, since each panel can usually produce about 250 to 400 watt-hours per hour, the average home will need 20 to 35 panels.
