Factors that Affect Solar Panel Costs in Mount Vernon
Cost is typically one of the most important factors for homeowners wanting to invest in solar. There are a few major factors that affect your total cost in Mount Vernon: 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
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 uses, the larger your system will likely need to be. You can expect to spend around $3,760 per kilowatt in Mount Vernon.Some solar brands — like Maxeon from SunPower — cost more upfront but also tend to offer higher efficiency. In a city like Mount Vernon, where sunlight is relatively abundant, efficiency can quickly pay off. In addition, 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
If paying for solar panels in cash is out of reach, solar loans are a popular option because they reduce your upfront costs and allow you to pay for your system over a term of, on average, between five and seven years.It’s wise to include the interest you’ll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and the amount of time it’ll take to pay off the loan.
Solar Panel Installation Company
The solar installer you opt for to handle your switch to sustainable energy can play a role in your total costs. There are about 3 solar installation companies operating throughout Mount Vernon, and each can charge different amounts for labor and equipment.Companies that 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 cost more. It’s best to do some research and choose a company that has the products, warranties and services you’re looking for and also fits within your budget.

How to Save on Solar Panels
The solar installer you go with will be a major factor in determining not only your overall costs, but also the types of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are several important things you should consider, including:
- Contract: Before signing a contract with a solar installer, make sure to read it through carefully so you understand the terms. Also, ask questions if you’re unsure about some of the terms, such as what to do if a part breaks or malfunctions and if there are any guarantees about energy production.
- Installation Process: When going solar, it’s important to keep an open line of communication with your solar company. Confirm that you understand how the installation process will go and the project completion timeline.
- Reputation: Companies that have been operating for many years 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 quality aftercare and customer service, such as part repairs and replacements.
- Solar Panel Brands: Different companies offer different brands and kinds of panels. If you know you want a specific brand, make sure the solar company you’re considering has it.
