Factors that Affect Solar Panel Costs in Sudbury

The cost of installing a solar system in Sudbury can vary by more than $10,000 from home to home. Your actual cost is dependent on several factors. The most significant one is the size of the system your household needs, and other factors include the equipment you choose, financing options and the solar installer you choose.

Solar Equipment

System size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of installing solar panels. That’s why it’s crucial to accurately assess the size of the solar energy system needed for your home by figuring out your energy needs.The brand and type of equipment you want for your solar system can raise or lower the price quite significantly. If you prefer a brand name like Tesla or SunPower, these are often more expensive than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have a small roof or just want maximum energy production, you can expect a higher equipment cost, but this can typically lead to greater savings over time. Plus, if you want extra equipment like an electric vehicle charger or solar batteries, this will also raise the cost.

Solar Financing Terms

For some homeowners, paying for solar out of pocket can be challenging. Solar loans are offered by most installers in Sudbury, which can lower, or in some cases totally eliminate, your upfront costs to make solar more accessible.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 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 considerably.

Solar Panel Installation Company

A final factor to consider when trying to figure out the cost of solar for your home or business in Sudbury is the company you hire to install your solar panel system. As with choosing a company to renovate your kitchen, for example, you’ll have no shortage of solar installers that provide a range of services at different price points.Additionally, some companies in Sudbury have more knowledge about local solar incentives and can help you make good use of additional rebates or tax exemptions. Though, they may charge more for that service. Even if they cost more upfront, they could help you save more money in the long run.

How to Save on Solar Panels

The solar panel company you choose will affect not only your overall costs, but also the types of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are some important things you should take into account, including:

  • Warranty: Warranties that provide coverage for panel repairs and maintenance over a long period of time such as 25 years are the best you can get in the business, and offering such a warranty is one mark of a good company.
  • Contract: Although reading through a contract can be tedious, it’s important to do it carefully so you can be sure you understand how much the equipment and services will cost and how part repairs and replacements will be handled.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for clean 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 look into your installer’s reputation is by reading reviews.
  • Solar Panel Brands: Each solar panel brand and kind offers varying levels of quality, durability and efficiency. They will come at different prices as well. The company you choose has an impact on which solar panel brands you have access to.

EcoWatch's Sudbury, MA Solar Cost FAQs

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

This is a difficult question to answer precisely, because the cost depends on a few different factors. Generally speaking, it costs about $20,300 for a 5-kW system and $40,600 for a 10-kW system after the ITC is applied. It will be more expensive if you want extra solar equipment or more efficient panels, or if you have higher-than-average energy needs. On the flip side, you can spend less if you go with 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 certainly one of the most important factors you should consider when buying solar panels, but other important factors include efficiency, durability, and quality.

Is going solar worth it?

Solar panels can be a great investment for many homeowners, but they might not be worth it for everyone. If your home doesn't get enough sunlight and/or your power bills are already reasonably low, solar panels might not be for you.

How many solar panels should I get to power my home?

The exact number of solar panels you need depends on your household energy needs and how much sunlight your roof gets. You can take a look at your energy bills for the past year to get an idea of the solar system size you'll need. The average household has to get between 20 and 35 panels to cover their typical energy usage.
