Factors that Affect Solar Panel Costs in Johnston City

Cost is typically one of the most important factors for homeowners considering investing in solar. There are a few primary factors that will push your cost above or below the average in Johnston City: solar equipment and system size, financing options and the solar installation company you choose. We'll go over each of these briefly below.

Solar Equipment

The size of the solar energy 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 about $2,730. The brand and kind 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 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

Many homeowners find the average cost of solar in Johnston City to be too costly, even if the investment pays off over time. Fortunately, almost every solar company in the area provides access to financing options. Solar loans greatly decrease upfront costs for most homeowners, but they also result in a higher cost over time because of interest. Although solar loans make going solar more accessible for Johnston City homeowners, they can also raise the total you pay for your system, depending on your interest rate and how long you take to pay off the loan. If you put down a larger down payment, though, you can cut back on how much interest you have to pay.

Solar Panel Installation Company

A final consideration when trying to estimate the cost of solar for your home or business in Johnston City is the company you hire to install your PV system. Similar to choosing a company to install new cabinets, for example, there are plenty of solar installers that offer a range of services at different price points. Larger national companies usually have lower costs, but some local companies keep up with them by promoting sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or extra services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels

The company that does your system installation will affect the warranties and brands available to you, and it will also have an impact on your total cost. Since choosing a company can be a tough decision, we have some tips to help you, such as:

  • Installation Process: Make sure you're aligned with the company with regard to how the installation process will go and what you need to do before your solar system is installed, such as repairing your electrical system or roof.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for sustainable energy professionals. If your solar panel installer is NABCEP-certified, it likely has a solid reputation and is qualified to do the job well. Another way you can research your installer's reputation is by reading reviews.
  • 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 expectations you should have about your solar system's energy production.
  • Solar Panel Brands: The kind of solar panel you'd like to get plays a part in which installer you should go with, since different companies have access to different panels.

Generally speaking, it costs about $13,650 for a 5-kW system and $27,300 for a 10-kW system after the ITC is applied.

Do solar panels increase your home value?

Installing solar panels on your home can increase the value of your property by about 4%, according to research done by Zillow.
