Factors that Affect Solar Panel Costs in Greenwich
There are a number of criteria that can determine your solar panel installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar system.
Solar Equipment
The cost of solar panels varies by thousands of dollars due to some different factors. One of the notable factors is the system size, which is measured in kilowatts (kW). Solar power systems that have higher efficiency or power production need better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $3,530.The type of solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you choose the most efficient solar panel brands, you’ll end up paying more upfront than if you opted for the most affordable panels. On the other hand, higher efficiency could save you more over time on your energy bills. In addition, extra products, such as solar batteries, can bump up your total well above the Greenwich average.
Solar Financing Terms
For some homeowners, paying for solar out of pocket can be challenging. Solar loans are offered by most installers in Greenwich, which can reduce, or in some cases totally eliminate, your upfront costs to make solar more affordable.When considering your overall cost, you should also calculate the interest you’ll pay if you decide on a solar loan. Also, paying more upfront can lower the total interest paid over time.
Solar Panel Installation Company
The solar company you opt for to handle your switch to sustainable energy can have an effect on your total costs. There are about 3 solar panel companies operating throughout Greenwich, and each can charge varying 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 prices because they have greater resources and bulk pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or discount can bring their pricing down to compete with bigger companies.
