Factors that Affect Solar Panel Costs in St. Marys
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
System size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of installing solar panels. For that reason, it’s crucial to accurately gauge the size of the solar energy system needed for your home by figuring out your typical energy use.There are a lot of different solar panel brands and the one you pick also changes the cost. Generally speaking, the brands that are more efficient tend to also cost more. Additionally, the type of equipment you’re looking to get can affect your total cost. If you just need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
For some homeowners, paying for a solar system out of pocket can be challenging. Solar loans are offered by most installers in St. Marys, which can reduce, or in some cases totally eliminate, your upfront costs to make solar more affordable.Though solar loans make going solar more accessible for St. Marys homeowners, they can also raise the total you pay for your system, depending on your interest rate and how long you take to pay off the loan. If you put down a larger down payment, though, you can cut back on how much interest you have to pay.
Solar Panel Installation Company
The solar installation company you pick will impact your total cost to adopt solar power. Different companies will charge different amounts for the equipment and labor.The size of the company sometimes plays the most significant role in your costs. Larger national companies, like SunPro and Sunrun, often have lower pricing because of greater resources and bulk 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 names.
