Factors that Affect Solar Panel Costs in Key Largo
The cost of installing a solar system in Key Largo can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The most significant one is the size of the system you need, and other factors include equipment choices, financing options and the solar installer you choose.
Solar Equipment
The size of the solar panel 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, you can expect your total to increase by around $3,210. The brand and type of equipment you want for your solar system can raise or lower the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these are often more expensive than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have limited roof space or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to more savings over time. Plus, if you want add-ons like an electric vehicle charger or solar batteries, this will also increase the cost.
Solar Financing Terms
Solar panels can save you money on power bills over many years, but they can also be a significant investment. That’s why many Key Largo homeowners choose to finance their solar panel systems to make paying for solar more affordable.However, the interest on solar loans also adds to your overall costs, so it’s vital to include that in your estimate as well. You can always reduce the total you pay in interest and sometimes even your APR by making a larger down payment.
Solar Panel Installation Company
The solar panel installation company you pick will influence your total cost to make the switch to solar . Different companies will bill different amounts for the equipment and labor.Companies that only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come with an above-average cost. It’s best to do some research and find a company that provides the products, warranties and services you want and also fit into your budget.
