Factors that Affect Solar Panel Costs in Hopkinton
Though the average cost of a solar system in Hopkinton is $12,674, your actual cost may be above or below the average. There are many factors that can have a sizable impact on the cost of a solar system installation. Below are some of the more crucial things to keep in mind.
Solar Equipment
Solar system size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of installing solar panels. That’s why it’s important to accurately assess the size of the solar energy system needed for your home by figuring out your energy needs.The type of solar panels and equipment you want is another factor that will significantly influence costs. Solar panels that are more efficient, like monocrystalline panels, tend to come at a higher price. Further, solar equipment consists of more than just the solar panels themselves. You’ll also need to decide on the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when looking for a solar system that falls within your budget.
Solar Financing Terms
Most solar installers in Hopkinton offer solar loans, which reduce your upfront costs of installing a solar system.However, the interest on solar loans also increases your all-in costs, so it’s vital to include that in your estimate as well. You can always bring down the total you pay in interest and sometimes even your APR by making a larger down payment.
Solar Panel Installation Company
The solar company you choose to handle your switch to clean energy can have an effect on your total costs. There are about 3 solar installation companies in Hopkinton, and each can charge varying 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 decide on the company that has the products, warranties and services you want and also is within your budget.
