Factors that Affect Solar Panel Costs in Hopkinton

There are several factors that can affect your solar system 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

The cost of solar panel systems varies by thousands of dollars due to a few different factors. One of the major factors is the system size, which is measured in kilowatts (kW). Solar power systems that have better efficiency or power generation require 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 $4,070.There are several different solar panel brands and the one you choose also affects the cost. Generally, the brands that offer higher efficiency tend to also be more expensive. In addition, the type of equipment you choose can affect your total cost. If you only 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 solar out of pocket can be a challenge. Solar loans are offered by most installers in Hopkinton, which can bring down, or in some cases totally eliminate, your upfront costs to make solar more affordable.When trying to figure out your overall cost, you should also calculate the interest you’ll pay if you go with a solar loan. Also, paying more upfront can reduce the total interest paid over time.

Solar Panel Installation Company

Finally, the company you hire to install your solar panels can influence the cost. Hopkinton’s solar companies all have different labor costs and add varying upcharges to equipment. You may see national solar installers that have lower prices due to their bigger brand name and access to bulk pricing, or you might see small, local installation companies offering deals or promotions to compete with those larger companies.
