Factors that Affect Solar Panel Costs in Westwood

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

Solar Equipment

The size of the solar panel system you need for your home, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, your total will most likely increase by about $2,940. The kind of solar panels and equipment you get is another factor that will substantially influence costs. Solar panels that are more efficient, like monocrystalline panels, tend to cost more. Plus, solar equipment is more than just the solar panels themselves. You'll also need to decide on the kind of racks used to mount the panels, inverters, solar batteries, etc. It's important to take all of this into consideration when researching a solar system that falls within your budget.

Solar Financing Terms

Solar panels can save you money on power bills over time, but they can also be a big investment. That's why many Westwood homeowners choose to finance their solar panel systems to offset upfront costs. When trying to figure out your overall cost, you should also calculate the interest you'll pay if you opt for a solar loan. Also, paying a higher down payment can lower the total interest paid over time.

Solar Panel Installation Company

The solar company you choose to handle your switch to sustainable energy can play a part in your total costs. There are about 3 solar installation companies operating throughout Westwood, and each can charge different amounts for labor and equipment. Additionally, some companies in Westwood are more knowledgeable about local solar incentives and can help you make good use of additional rebates or tax exemptions. However, they may charge more for that service. Even if they cost more upfront, they could end up saving you more money in the long run.

How to Save on Solar Panels

Since the model of solar panels and the company you choose significantly affects your costs and your system's efficiency, production, and durability, it's important to pick the right ones for you. Here are some things to keep in mind to help with your decision:

  • Installation Process: Make sure you're on the same page with the company with regard to how the installation process will go and what needs to be done before your solar panels are installed, such as repairing your electrical system or roof.
  • Reputation: Long-standing companies likely have a high reputation. This is important because it ensures that it will not only see your solar installation through, but will also provide adequate aftercare and customer support, such as part repairs and replacements.
  • Solar Panel Brands: Homeowners will have different preferences for panels depending on their roof configurations and energy needs. Even though there are many options for which kind of solar panel you can get, not every company will have access to the exact one you may want or need, so make sure you peruse their list of options before deciding.
  • Contract: When looking over your solar installer's contract, ask questions about any terms you're not sure of and be sure you understand what happens in scenarios such as a system part breaking or if the company goes out of business.

EcoWatch's Westwood, MA Solar Cost FAQs

What is the average cost of installing solar panels in Westwood?

The average cost of solar panels in Westwood 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 things such as the type of solar panels you want, what size system you need and how much energy you use.

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

Leasing solar panels can be an appealing choice, because it commonly comes with low or $0 upfront payments. The drawback is that you won't be able to save as much. If you lease, you don't own the system, so you can't claim any incentives and your home value won't increase. Buying solar panels is a better way to go if you want to get the most savings.

How much can I save on power bills after switching to solar?

Solar panels can potentially eliminate your electricity bills depending on your location and the efficiency of your system. Even if it doesn't get rid of them completely, you can save a lot of money on your bills, about $1,153.80 per year.

How often do you have to replace solar panels?

Although the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable at that time. What this means is their energy production will have decreased significantly after that point. You can opt to replace them once you've had them for that long or you can continue to use them at a lower efficiency.
