Factors that Affect Solar Panel Costs in Charlton

Cost is typically one of the most important factors for homeowners considering investing in solar. There are a few major factors that determine your overall cost in Charlton: solar equipment and system size, financing options and the solar installation company you choose. We'll go over each of these briefly below.

Solar Equipment

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

Solar Financing Terms

Many homeowners find the average cost of solar in Charlton to be too expensive, even if the investment pays off over time. Thankfully, almost every solar company in the area offers financing options. Solar loans remarkably decrease upfront costs in most cases, but they also lead to higher prices over time due to interest. You'll have to consider the long-term cost of financing options, 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 APR could reduce your costs significantly.

Solar Panel Installation Company

A final factor to consider when trying to figure out the cost of solar for your home or business in Charlton is the company you get to install your PV system. As with choosing a company to build a deck or pool, for example, there's no shortage of solar installers that provide a range of services at different price points. Some companies 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 come at a higher cost. It's best to do some research and find a company that offers the products, warranties and services you want and also fit into your budget.

How to Save on Solar Panels

There are a lot of solar installers to choose from, all of which offer different warranties, solar panel models and price points. To help you find the right company for you, here are some tips to keep in mind:

  • Installation Process: Get detailed information from your solar company about the installation process and what to expect, including when the site survey will be completed and what the project timeline is.
  • Warranty: If you're concerned about the endurance of your solar system, ensuring your company offers a 25-year, all-inclusive warranty can give you some peace of mind.
  • Contract: Read the contract terms thoroughly to make sure you understand the overall cost, project timeline incentives and warranties.
  • Solar Panel Brands: Each solar panel brand and model offers varying levels of quality, longevity and energy efficiency. They will come at different prices as well. The company you choose plays a role in which solar panel brands you have access to.

EcoWatch's Charlton, MA Solar Cost FAQs

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

This is a hard question to answer precisely, 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 be more expensive if you want other solar equipment or more efficient panels, or if you have higher-than-average energy needs. Conversely, you can spend less if you choose a smaller solar panel system or cheaper solar panels.

Is cost the most important consideration 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 your goals for going solar. In places where rooftop space is limited, efficiency can trump the cost. Other factors that are important to be mindful of are the quality and durability of your solar panels.

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

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

How often do you have to replace solar panels?

On average, solar panels can last about 25 to 30 years. Some even last up to 50 years, but their efficiency goes down by about 0.8% each year. You can choose to replace them sooner if you want to maintain a higher amount of energy production.
