Factors that Affect Solar Panel Costs in Bay St. Louis

The cost of installing a solar system in Bay St. Louis can vary by more than $10,000 from home to home. Your actual cost is dependent on several factors. The largest one is the size of the system your household needs, and other factors include equipment choices, financing options and the solar company you choose.

Solar Equipment

The cost of solar panels varies by thousands of dollars due to a variety of factors. One of the most significant factors is the system size, which is measured in kilowatts (kW). Solar power systems that have higher efficiency or power production require 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 $3,140.The brand and kind 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 are often more expensive 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 more savings over time. Plus, if you want extra equipment like an electric vehicle charger or solar batteries, this will also raise the cost.

Solar Financing Terms

For some homeowners, paying for solar out of pocket can be a challenge. Solar loans are provided by most installers in Bay St. Louis, which can lower, or in some cases completely eliminate, your upfront costs to make solar more affordable.When trying to figure out your overall cost, you should also calculate the interest you’ll pay if you go with a solar loan. Also, paying a higher down payment can lower the total interest paid over time.

Solar Panel Installation Company

Lastly, the company you opt for to install your solar panel system can impact the cost. Bay St. Louis’s solar companies all have different labor costs and add varying upcharges to equipment. The size of the company sometimes plays the most considerable role in the cost of installation. Larger national companies, like SunPro and Sunrun, often have lower prices because they have 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 discount can bring their pricing down to compete with bigger names.

How to Save on Solar Panels

The solar panel company you opt for will impact not only your total costs, but also the kinds of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are some important things you should consider, such as:

  • Solar Panel Brands: Homeowners will have different preferences for panels depending on their roof configurations and energy needs. Although there are many options for which brand of solar panel you can get, not every company will have access to the exact one you may want or need, so make sure you take a look at their list of offerings before deciding.
  • Warranty: A high-quality company stands out from other companies by providing the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
  • Installation Process: When making the switch to solar, it’s crucial to maintain an open line of communication with your solar company. Confirm that you understand how the installation process will go and the completion timeline.
  • Contract: Before signing a contract with a solar installer, make sure to look it over completely so you understand the terms. Also, ask questions if you’re not certain about some of the terms, such as what to do if a component breaks or malfunctions and if there are any guarantees about energy production.
