Factors that Affect Solar Panel Costs in Castleton
Cost is usually one of the most important factors for homeowners who want to invest in solar. There are a few primary factors that determine your overall cost in Castleton: 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 significant 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 power your household uses, the larger your system will likely need to be. You can expect to pay around $3,850 per kilowatt in Castleton.Some solar brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer better efficiency. In a city like Castleton, where sunlight isn’t as abundant, efficiency can quickly pay off. In addition, 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 Castleton to be too steep, even if the investment pays off over time. Fortunately, almost every solar installer in the area offers financing options. Solar loans greatly decrease upfront costs in most cases, but they also result in a higher cost over time due to interest.When considering your overall cost, you should also calculate the interest you’ll pay if you choose to go with a solar loan. Also, paying more on your down payment can lower the total interest paid over time.
Solar Panel Installation Company
A final factor to keep in mind when trying to estimate the cost of solar for your home or business in Castleton is the company you get to install your solar panel system. Similar to choosing a company to renovate your kitchen, for example, there’s no shortage of solar installers that offer a range of services for different budgets.Companies that only sell high-efficiency and high-priced products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come with an above-average cost. It’s best to do some research and choose a company that provides the products, warranties and services you’re looking for and also is within your budget.
