Factors that Affect Solar Panel Costs in St. Joseph
While the average cost of a solar system in St. Joseph is $17,170, your actual cost may differ. There are many factors that can have a sizable impact on the cost of a solar panel installation. Below are some of the more crucial things to take into consideration.
Solar Equipment
The size of the solar panel system you need to offset your energy usage, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, your total will most likely increase by around $3,370. The brand and type of equipment you get 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 a small roof 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 extra equipment 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 big investment. That’s why many St. Joseph homeowners choose to finance their solar panel systems to make going solar more affordable.However, the interest on solar loans also increases your overall costs, so it’s important to take that into consideration as well. You can always lower the total you pay in interest and sometimes even your APR by making a larger down payment.
Solar Panel Installation Company
The final major cost factor you should consider is the installer you choose. Given the booming popularity of renewable energy solutions in St. Joseph, you’ll have many options to choose from, but each comes at different price points for labor and equipment.You may notice national solar installers that have lower prices because of their bigger brand name and access to bulk equipment prices, or you might see small, local installation companies offering deals or promotions to compete with those larger companies.
