Factors that Affect Solar Panel Costs in Germantown

Although the average cost of a solar system in Germantown is $19,492, your final cost may differ. There are many factors that can have a significant impact on the cost of a residential solar panel installation. Below are some of the more important things to consider.

Solar Equipment

When it comes to estimating the price of a solar panel system in Germantown, one of the most important factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are mainly based on your home’s energy usage, which you can gauge by looking at past energy bills. Your overall cost can increase by around $3,880 for each additional kilowatt you need.The brand and type 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 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 can expect 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 Germantown to be prohibitively costly, even if the investment pays off over time. Fortunately, nearly every solar company in the area provides financing options. Solar loans remarkably decrease upfront costs for most homeowners, but they also result in a higher cost over time because of interest.While solar loans make going solar more accessible for Germantown homeowners, they can also increase the total you pay for your system due to interest. If you put down a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

The remaining key cost factor you should consider is the installer you choose. Given the booming popularity of green energy solutions in Germantown, you’ll have many options to choose from, but each comes at various price points for labor and equipment.The size of the company sometimes plays the most considerable role in your total costs. Larger national companies, like SunPro and Sunrun, often have lower prices due to more resources and better 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.

How to Save on Solar Panels

There are many solar installers to choose from, all of which offer different warranties, solar panel models and price points. To help you pick the right company for you, here are some tips to keep in mind:

  • Installation Process: An important thing to understand when adopting solar power is the installation process itself. Be sure to clarify any details you should know with your solar company, such as what permits you should acquire and what the project timeline is.
  • Contract: It’s important to look over your solar installer’s contract carefully to understand what services they will provide, what the warranty covers and what you can expect about the project timeline.
  • Warranty: Companies typically offer different types of warranties that provide different kinds of coverage. A 25-year, all-inclusive warranty is the gold standard.
  • Solar Panel Brands: Homeowners will have different preferences for panels depending on their locations and energy needs. Even though there are many options for which type of solar panel you can get, not every company will have the exact one you may want or need, so be sure to take a look at their list of offerings before deciding.
