Factors that Affect Solar Panel Costs in Falls Church

For many Falls Church homeowners, the decision to adopt solar energy depends on cost. However, the range of solar installation costs can be quite wide in Falls Church, with typical prices between $20,000 to $40,000. There are a number of factors that considerably influence the price you’ll pay, which we'll go over below.

Solar Equipment

One of the most significant factors to consider when it comes to the cost of adopting solar energy is the size of the solar system, which is measured in kilowatts (kW). The more electricity your household consumes, the larger your system will likely need to be. You can expect to spend about $3,590 per kilowatt in Falls Church.The kind of solar panels and equipment you get is another factor that will largely impact costs. Solar panels that are more efficient, like monocrystalline panels, tend to cost more. Furthermore, solar equipment is more than just the solar panels themselves. You’ll also need to decide on the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when looking into a solar system that falls within your budget.

Solar Financing Terms

If paying for a solar system in cash is too expensive, solar loans are a solid choice because they lower your upfront costs and allow you to pay for your system over five to seven years on average.When figuring out your overall cost, you should also calculate the interest you’ll pay if you go with a solar loan. Also, paying more upfront can lower the total interest paid over time.

Solar Panel Installation Company

A final factor to consider when trying to figure out the cost of solar for your home or business in Falls Church is the company you get to install your solar panel system. Similar to choosing a company to build a deck or pool, for instance, there are plenty of solar installers that offer a range of services for different budgets.Larger national companies usually have lower costs, but some local companies undercut them by offering sales and discounts. While the smaller companies might not have access to 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

Since the type of solar panels and the installation company you choose greatly affects your costs and your system’s efficiency, production, and durability, it’s important to pick the right ones for you. Here are some tips to keep in mind to help with your decision:

  • Installation Process: An important thing to understand when adopting solar energy 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 how long the project will take.
  • Contract: When looking over your solar company’s contract, ask questions about any terms you’re not sure of and be sure you understand what happens in scenarios like a system component breaking or if the company goes out of business.
  • Solar Panel Brands: Different companies will have different brands and kinds of panels. If you want a specific brand, make sure the solar panel installer you’re considering has it.
  • Reputation: Solar companies that have great reviews from their customers and that have been in business for many years most likely provide good-quality solar panel installation and expertise.
