Factors that Affect Solar Panel Costs in Ashburn

Cost is typically one of the most important factors for homeowners who are considering investing in solar. There are a few key factors that determine your overall cost in Ashburn: solar equipment and system size, financing options and the solar installation company you choose. We'll cover each of these briefly below.

Solar Equipment

The size of the solar energy system you need for your home, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by around $2,750. Some solar brands — like Maxeon from SunPower — are more costly upfront but also tend to offer higher efficiency. In a city like Ashburn, where sunlight is relatively abundant, efficiency can quickly pay off. In addition, if you have a small roof or limited space for your panels, higher efficiency options will be more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

Many homeowners find the average cost of solar in Ashburn to be prohibitively costly, even if the investment pays off over time. Fortunately, nearly every solar installer in the area provides access to financing options. Solar loans remarkably decrease upfront costs in most cases, but they also result in paying more over time because of interest. You'll have to consider the long-term cost of loans, including the total 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 more than the original cost. Making a larger down payment or securing a solar loan with a low APR could reduce your costs significantly.

Solar Panel Installation Company

Lastly, the company you choose to install your solar panel system can impact the cost. Ashburn's solar companies all have different labor costs and add varying upcharges to equipment. Larger national companies generally have lower costs, but some local companies compete 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 car charger installation, they might be cheaper overall.

How to Save on Solar Panels

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

  • Reputation: Solar companies that have great reviews from their customers and that have been in business for many years in most cases offer quality solar panel installation and expertise.
  • Solar Panel Brands: Each solar panel brand and kind offers varying levels of quality, durability and energy efficiency. They will come at different price points as well. The company you choose has an impact on which solar panel brands you have access to.
  • Warranty: A high-quality company rises above other companies by offering the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
  • Contract: When reading through your solar company's contract, ask questions about any terms you're not sure of and make sure you understand what happens in scenarios like a system component breaking or if the company goes out of business.
