Factors that Affect Solar Panel Costs in South Duxbury

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

Solar Equipment

The cost of solar panels varies by thousands of dollars due to a few different factors. One of the notable factors is the system size. Solar power systems with higher efficiency or power generation need better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $2,940. Some solar brands — like Maxeon from SunPower — are more costly upfront but also tend to offer better efficiency. In a city like South Duxbury, where sunlight is relatively abundant, efficiency can quickly pay off. In addition, if you have a small roof or limited space for your panels, higher efficiency options will be more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

For some homeowners, paying for solar out of pocket can be financially overwhelming. Solar loans are available from most installers in South Duxbury, which can bring down, or in some cases totally eliminate, your upfront costs to make solar more affordable. You'll have to consider the long-term cost of loans, 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 getting a solar loan with a low interest rate could reduce your costs remarkably.

Solar Panel Installation Company

The last major cost factor you should take into consideration is the installer you choose. Given the booming popularity of sustainable energy solutions in South Duxbury, you'll have a great number of options to choose from, but each comes at various price points for labor and equipment. Larger national companies usually have lower costs, but some local companies compete with them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or additional services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels

The solar installer you go with will influence 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 some important things you should keep in mind, such as:

  • Reputation: Companies that have been in business for many years likely have a good reputation. This is important because it ensures that it will not only see your solar project through, but will also provide quality aftercare and customer support, such as part repairs and replacements.
  • Solar Panel Brands: The type of solar panel you want plays a part in which company you should go with, since different companies have different panels.
  • Contract: Look through the contract terms thoroughly to make sure you understand the total cost, project timeline rebates and warranties.
  • Installation Process: Homeowners should understand how exactly the installation process will go, as well as important factors like the completion timeline.

EcoWatch's South Duxbury, MA Solar Cost FAQs

How much does it cost to install solar panels in South Duxbury?

This is a tough question to answer exactly, because the cost depends on many 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 other solar equipment or higher quality panels, or if you have higher-than-average energy usage. Conversely, you can spend less if you choose a smaller solar panel system or cheaper solar panels.

What other factors should I consider in addition to cost when buying solar panels?

The upfront cost is a very important factor to consider, but whether it's the most important for you depends on why you decided to go solar. In places where rooftop space is limited, efficiency can trump the cost. Other factors that are important to keep in mind are the quality and durability of your solar panels.

How will solar panels impact my home value?

Solar panels can increase the value of your home remarkably as long as you buy or finance your panels and don't choose a solar lease or power purchase agreement (PPA). According to research done by Zillow, the average home value increases by about 4.1% after installing solar panels."

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

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