Factors that Affect Solar Panel Costs in West Islip
There are several factors that can influence your installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that performs the installation.
Solar Equipment
When it comes to estimating the cost of a solar energy system in West Islip, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are mainly based on your home’s energy usage, which you can gauge by looking at past electricity bills. Your total cost can increase by around $3,650 for each additional kilowatt you need.The brand and type of equipment you want for your solar system can increase or decrease the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these often come at a higher price than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have a small roof or just want maximum energy production, you can expect a higher equipment cost, but this can typically lead to greater savings over time. Also, if you want additional equipment like an electric vehicle charger or solar batteries, this will also increase the cost.
Solar Financing Terms
For some homeowners, paying for a solar system out of pocket can be a challenge. Solar loans are offered by most installers in West Islip, which can lower, or in some cases totally eliminate, your upfront costs to make solar more accessible.Though solar loans make adopting solar energy more accessible for West Islip homeowners, they can also add to the total you pay for your system, depending on your interest rate. If you make a larger down payment, though, you can avoid paying as much in interest.
Solar Panel Installation Company
A final factor to keep in mind when trying to estimate the cost of solar for your home or business in West Islip is the company you hire to install your solar panel system. Similar to choosing a company to build a deck or pool, for instance, you’ll have no shortage of solar installers that provide a range of services at different costs.The size of the company sometimes plays the most significant role in your total costs. Larger national companies, like SunPro and Sunrun, often have lower prices because of access to more 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 companies.
