Factors that Affect Solar Panel Costs in Cohasset
The cost of installing a solar system in Cohasset can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The largest one is your system size, and other factors include the equipment you choose, financing options and the solar company you choose.
Solar Equipment
The size of the solar system you need, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, your total will most likely increase by about $4,060. There are several different solar panel brands and the one you pick also affects the cost. Usually, the brands that have better 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 far less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
If paying for a solar system out of pocket is too expensive, solar loans are a popular option because they reduce your upfront costs and allow you to pay for your system over five to seven years on average.You’ll have to consider the long-term cost of financing options, including the total interest you’ll pay over the length of the loan. If you’re only able to get a high-interest loan, then your total can be hundreds or even thousands of dollars more than the principal cost. Making a larger down payment or securing a solar loan with a low interest rate could reduce your costs significantly.
Solar Panel Installation Company
The final key cost factor you should keep in mind is the installer you choose. Given the booming popularity of renewable energy solutions in Cohasset, you’ll have plenty of options to choose from, but each comes at various price points for labor and equipment.You may come across national solar installers that have lower prices due to their larger brand name and access to bulk pricing, or you might see small, local installation companies offering deals or promotions to compete with those major players.
