Factors that Affect Solar Panel Costs in Sterling
The cost of installing a solar system in Sterling 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 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, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, your total will most likely increase by about $3,590. The brand and kind of equipment you choose 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 have a higher price tag 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 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 significant investment. That’s why many Sterling homeowners decide to finance their solar panel systems to offset upfront costs.You’ll have to consider the long-term cost of loans, including the amount of interest you’ll pay over the length of the loan. If you’re only able to get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or finding a solar loan with a low interest rate could reduce your costs remarkably.
Solar Panel Installation Company
The remaining significant cost factor you should keep in mind is the installer you choose. Given the booming popularity of clean energy solutions in Sterling, you’ll have plenty of options to choose from, but each comes at various price points for labor and equipment.The size of the company sometimes plays the most significant role in the cost. Larger national companies, like SunPro and Sunrun, often have lower pricing because they have greater 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 discount can bring their pricing lower to compete with bigger names.
