Factors that Affect Solar Panel Costs in Chantilly

The cost of installing a solar system in Chantilly can vary by more than $10,000 from home to home. Your actual cost is determined by several factors. The most significant one is the size of the system your home needs, and other factors include the equipment you choose, financing options and the solar company you choose.

Solar Equipment

Solar system size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of going solar. That's why it's a priority to accurately gauge the size of the solar energy system needed for your home by figuring out your average energy use. Some solar brands — like Maxeon from SunPower — cost more upfront but also tend to offer better efficiency. In a city like Chantilly, 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 a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

For some homeowners, paying for solar out of pocket can be financially overwhelming. Solar loans are available from most installers in Chantilly, which can reduce, or in some cases eliminate, your upfront costs to make solar more affordable. However, the interest on solar loans also adds to your all-in costs, so it's crucial to take that into consideration as well. You can always lower the total you pay in interest and possibly even your APR by making a larger down payment.

Solar Panel Installation Company

The final significant cost factor you should take into consideration is the installer you choose. Given the booming popularity of clean energy solutions in Chantilly, you'll have a great number of options to choose from, but each comes at different price points for labor and equipment. Some companies only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally cost more. It's best to do some research and find a company that has the products, warranties and services you want and also fits within your budget.

How to Save on Solar Panels

The company that does your solar 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 challenge, we have some tips to help you, such as:

  • Solar Panel Brands: Different companies carry different brands and types of panels. If you know you want a specific brand, make sure the solar company you're considering has it.
  • Contract: When reading through 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 part breaking or if the company goes out of business.
  • Reputation: Make sure your solar installer has a good reputation by confirming it has certifications and licenses, checking its work history and reading reviews by previous customers and solar experts like EcoWatch.
  • Warranty: A quality company stands out from other companies by providing the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.

EcoWatch's Chantilly, VA Solar Cost FAQs

What is the average cost of installing solar panels in Chantilly?

The average cost of solar panels in Chantilly is about $13,750 for a 5-kW system and $27,500 for a 10-kW system before the ITC, but the real cost will depend on certain factors like the kind of solar panels you want, what size system you need and how much energy you use.

Is it better to lease or buy solar panels in Chantilly?

Leasing solar panels can be an attractive choice, as it typically comes with low or $0 upfront payments. The drawback is that you won't be able to save as much. If you lease, you don't own the system, so you can't claim any incentives and your home value won't increase. Buying solar panels is a better option if you want to maximize your savings.

Can you sell solar power back to the grid in Chantilly?

Each state has some kind of net metering programs except Tennessee, South Dakota and Alabama currently. Some states allow you to sell power back to the grid, but others just offer you credit toward your future energy bills.

How often do you have to replace solar panels?

On average, the lifespan of solar panels is about 25 to 30 years. Some even last up to 50 years, but their efficiency decreases by about 0.8% each year. You can choose to replace them sooner if you want to maintain a higher level of energy production.
