Factors that Affect Solar Panel Costs in Mendon
There are several factors that can influence your total installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar panels.
Solar Equipment
The size of the solar system you need, 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 nearly $4,060. Some solar panel brands — like Maxeon from SunPower — cost more upfront but also tend to offer better efficiency. In a city like Mendon, where sunlight is relatively abundant, efficiency can quickly pay off. Plus, if you have a small roof or you don’t have a lot of 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
Solar panels can save you money on power bills over time, but they can also be a big investment. That’s why many Mendon homeowners decide to finance their solar panel systems to offset upfront costs.It’s wise to include the interest you’ll pay in your final cost estimate. If you can afford to pay a higher down payment, you can reduce your total costs and the amount of time it’ll take to pay off the loan.
Solar Panel Installation Company
Finally, the company you choose to install your solar panel system can influence the cost. Mendon’s solar companies all have different labor costs and add varying upcharges to equipment. The company’s size can sometimes play the most considerable role in the installation costs. Larger national companies, like SunPro and Sunrun, often have lower prices because of access to more resources and better pricing. Smaller local companies might be more costly, but they can sometimes have better customer service and more customization options, and the occasional sale or discount can bring their pricing down to compete with bigger companies.

How to Save on Solar Panels
The company that does your solar system installation will affect the warranties and brands available to you, and it will also have an impact on your total cost. Because selecting a company can be a challenge, we have some tips to help you, such as:
- Warranty: Warranties that cover replacement parts and repairs 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 indication of a quality company.
- Installation Process: One of the most important things to understand when going solar is the installation process itself. Be sure to clarify any details you should know with your solar company, such as what permits you should secure and what the project timeline is.
- Solar Panel Brands: Homeowners will have different preferences for panels depending on their roof configurations and how much efficiency they need. While there are many options for which kind of solar panel you can get, not every company will have the exact one you may want or need, so make sure you ask for their list of offerings before making your decision.
- Contract: Even though reading through a contract can be tedious, it’s important to do it thoroughly so you can make sure you understand what services your solar company will provide and the terms of the warranty.
