Factors that Affect Solar Panel Costs in St. Peters
The cost of installing a solar system in St. Peters can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The most significant one is your system size, and other factors include equipment choices, financing options and the solar company you choose.
Solar Equipment
One of the most significant factors to consider when it comes to the cost of installing solar panels is the size of the solar system, which is measured in kilowatts (kW). The more power your household uses, the larger your system will likely need to be. You can expect to pay about $3,370 per kilowatt in St. Peters.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 greater savings over time. Plus, if you want additional equipment like an electric vehicle charger or solar batteries, this will also raise the cost.
Solar Financing Terms
For some homeowners, paying for solar panels out of pocket can be challenging. Solar loans are available from most installers in St. Peters, which can bring down, or in some cases completely eliminate, your upfront costs to make solar more affordable.Although solar loans make switching to solar energy more accessible for St. Peters homeowners, they can also add to the total you pay for your system due to interest. If you make a larger down payment, though, you can cut back on how much interest you have to pay.
Solar Panel Installation Company
The solar panel installation company you choose will affect your total cost to make the switch to solar . Different companies will charge different amounts for the equipment and labor.You may notice national solar installers that have lower prices because of their larger brand name and access to bulk prices, or you might see small, local installation companies offering deals or promotions to compete with those major players.
