Factors that Affect Solar Panel Costs in Dedham
There are a number of criteria 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 system.
Solar Equipment
The cost of solar panel systems varies by thousands of dollars due to some different factors. One of the main factors is the system size, which is measured in kilowatts (kW). Solar power systems that have better efficiency or power production use 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 $4,060.Some solar panel brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer better efficiency. In a city like Dedham, where sunlight is relatively abundant, efficiency can quickly pay off. Also, if you have a small roof or limited space for your panels, higher efficiency options will be more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.
Solar Financing Terms
If paying for solar panels in cash is too expensive, solar loans are a popular route because they reduce your upfront costs and let you pay for your system over five to seven years on average.When figuring out your overall cost, you should also calculate the interest you’ll pay if you choose to go with a solar loan. Also, paying a higher down payment can reduce the total interest paid over time.
Solar Panel Installation Company
A final factor to consider when trying to evaluate the cost of solar for your home or business in Dedham is the company you get to install your solar system. As with choosing a company to build a deck or pool, for example, you’ll have no shortage of solar installers that offer a range of services for different budgets.The size of the company can sometimes play the most significant role in the cost of installation. Larger national companies, like SunPro and Sunrun, often have lower pricing because of access to 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 down to compete with bigger names.
