Factors that Affect Solar Panel Costs in Mount Sterling

Although the average cost of a solar system in Mount Sterling is $16,484, your actual cost may be above or below the average. There are several factors that can have a significant impact on the cost of a solar system installation. Below are some of the more important things to take into consideration.

Solar Equipment

One of the most important 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 electricity your household uses, the larger your system will likely need to be. You can expect to pay around $3,760 per kilowatt in Mount Sterling.The brand and type of equipment you want for your solar system can raise or lower the price quite significantly. If you prefer a 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 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 extra equipment like an electric vehicle charger or solar batteries, this will also raise the cost.

Solar Financing Terms

Many homeowners find the average cost of solar in Mount Sterling to be too steep, even if the investment pays off over time. Thankfully, almost every solar company in the area provides financing options. Solar loans substantially decrease upfront costs for most homeowners, but they also lead to a higher cost over time because of interest.It’s wise to add the interest you’ll pay in your final cost estimate. If you can afford to pay a higher down payment, you can reduce your total costs and how long it’ll take to pay off the loan.

Solar Panel Installation Company

The solar company you go with to handle your switch to renewable energy can play a role in your total costs. There are about 3 solar installation companies operating in Mount Sterling, and each can charge varying amounts for labor and equipment.You may notice national solar installers that have lower prices because of their bigger brand name and access to bulk prices, or you might see small, local installation companies offering deals or promotions to compete with those larger companies.
