Factors that Affect Solar Panel Costs in St Joseph

Although the average cost of a solar system in St Joseph is $12,058, your actual cost may be higher or lower than that. There are quite a few factors that can have a sizable impact on the cost of a solar system installation. Below are some of the more crucial things to keep in mind.

Solar Equipment

Solar system size, which is measured in kilowatts, is one of the largest factors that influences the overall cost of going solar. For that reason, it's crucial to accurately ascertain the size of the solar energy system needed for your home by figuring out your typical energy use. 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 limited roof space or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to greater savings over time. Also, 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 time, but they can also be a significant investment. That's why many St Joseph homeowners opt to finance their solar panel systems to make paying for solar more affordable. It's wise to factor 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 how long it'll take to pay off the loan.

Solar Panel Installation Company

A final factor to keep in mind when trying to figure out the cost of solar for your home or business in St Joseph is the company you get to install your solar panel system. As with choosing a company to renovate your kitchen, for example, you'll have many options for solar installers that provide a range of services for different budgets. The company's size sometimes plays the most significant role in the installation costs. Larger national companies, like SunPro and Sunrun, often have lower pricing because they have access to more resources and bulk 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 lower to compete with bigger names.

How to Save on Solar Panels

The company that does your solar system installation will affect the warranties and brands available to you, and it will also have an impact on your total cost. Since selecting a company can be difficult, we have some tips to help you, such as:

  • Contract: Although reading through a contract can take a lot of time, it's important to do it fully so you can be sure you understand how much the equipment and services will cost and the terms of the warranty.
  • Solar Panel Brands: Each solar panel brand and type has varying levels of quality, longevity and efficiency. They will come at different prices as well. The company you choose has an impact on which solar panel brands you have access to.
  • Warranty: If you care about the endurance of your solar panels, ensuring your installer offers a 25-year, all-inclusive warranty can help put you at ease.
  • Reputation: Your solar installer should have a good reputation as a company and have proven expertise in the field. Two ways to check this are to look for whether a company has technicians certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it has positive reviews from previous customers.
