Factors that Affect Solar Panel Costs in Westwood

Cost is typically one of the most important factors for homeowners who want to invest in solar. There are a few key factors that determine your overall cost in Westwood: solar equipment and system size, financing options and the solar installation company you choose. We'll cover each of these briefly below.

Solar Equipment

One of the most important factors to consider when it comes to the cost of going solar is the size of the solar system, which is measured in kilowatts (kW). The more energy your household consumes, the larger your system will likely need to be. You can expect to spend around $2,940 per kilowatt in Westwood. Some solar brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer higher efficiency. In a city like Westwood, where sunlight is relatively abundant, efficiency can quickly pay off. Plus, 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

If paying for a solar system out of pocket is out of reach, solar loans are an affordable route because they lower your upfront costs and let you pay for your system over five to seven years on average. When trying to figure out your overall cost, you should also calculate the interest you'll pay if you choose to go with a solar loan. Also, paying more upfront can lower the total interest paid over time.

Solar Panel Installation Company

A final factor to consider when trying to figure out the cost of solar for your home or business in Westwood is the company you hire to install your solar system. As with choosing a company to build a deck or pool, for example, there's no shortage of solar installers that offer a range of services at different costs. Some companies only sell high-quality, high-efficiency and high-price products — 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 has the products, warranties and services you want and also fit into your budget.

How to Save on Solar Panels

There are a lot of companies available in Westwood, and some homeowners feel overwhelmed considering their options. Picking the right company for you can be difficult, so here are some tips to help you decide:

  • Reputation: Make sure your solar company has a good reputation by confirming it has certifications and licenses, checking its number of years in business and reading reviews by previous customers and solar experts like the EcoWatch team.
  • Contract: Before signing a contract with a solar company, make sure to look it over fully so you understand the terms. Also, ask questions if you're unsure about some of the terms, such as what the warranty covers and if there are any guarantees about energy production.
  • Solar Panel Brands: Each solar panel brand and kind offers varying levels of quality, longevity and energy efficiency. They will come at different prices as well. The company you choose impacts which solar panel brands you have access to.
  • Installation Process: Homeowners should make sure they understand how exactly the installation process will go, as well as important factors like the project completion timeline.

EcoWatch's Westwood, MA Solar Cost FAQs

How much does it cost to install 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 actual cost will depend on stuff such as the type of solar panels you want, what size system you need and how much energy you consume.

What other factors should I consider apart from 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 areas where rooftop space is limited, efficiency can be more important than the cost. Other factors that are important to be mindful of are the quality and durability of your solar panels.

Can you sell solar power back to the grid in Westwood?

Most states offer net metering programs of some kind. Through these, you can get paid for the extra power your system generates or or receive credits to put toward future utility bills. Currently there are just three states that don't have any net metering laws: Alabama, Tennessee and South Dakota.

How often do you have to replace solar panels?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely at that time. What this means is how much energy they produce will have decreased significantly after that point. You can replace them once you've had them for that long or you can continue to use them at a lower efficiency.
