Factors that Affect Solar Panel Costs in Windsor
There are several 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 does the installation.
Solar Equipment
The size of the solar system you need for your home, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, your total will most likely increase by about $3,880. There are many different solar panel brands and the one you choose also affects the cost. Typically, the brands that offer higher efficiency tend to also cost more. Plus, the type of equipment you’re looking to get can affect your total cost. If you just 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 in cash is out of reach, solar loans are a popular choice because they lower your upfront costs and let you pay for your system over a term of, on average, between five and seven years.It’s wise to add the interest you’ll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and the amount of time it’ll take to pay back the loan.
Solar Panel Installation Company
The final key cost factor you should take into consideration is the installer you choose. Given the growing popularity of clean energy solutions in Windsor, you’ll have plenty of options to choose from, but each comes at varying price points for labor and equipment.Larger national companies typically have lower costs, but some local companies compete with them by offering sales and discounts.
