Factors that Affect Solar Panel Costs in Arlington
Even though the average cost of a solar system in Arlington is $20,388, your actual cost may be higher or lower than that. There are several factors that can have a sizable impact on the cost of a solar panel installation. Below are some of the more crucial things to consider.
Solar Equipment
Solar system size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of going solar. For that reason, it’s crucial to accurately assess the size of the solar energy system needed for your home by figuring out your typical energy use.There are several different solar panel brands and the one you pick also changes the cost. Typically, the brands that are more efficient tend to also cost more. In addition, the type of equipment you want to install can affect your total cost. If you only need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
Most solar companies in Arlington have solar loans, which reduce your upfront costs of installing a solar system.However, the interest on solar loans also increases your total costs, so it’s important to consider that as well. You can always bring down the total you pay in interest and in some cases even your APR by making a larger down payment.
Solar Panel Installation Company
The solar installer you hire to handle your switch to renewable energy can have an effect on your total costs. There are about 3 solar panel companies in Arlington, and each can charge different amounts for labor and equipment.The company’s size can sometimes play the most significant role in your total costs. Larger national companies, like SunPro and Sunrun, often have lower pricing because of greater 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 promotion can bring their pricing lower to compete with bigger companies.
