Factors that Affect Solar Panel Costs in Mclean

The cost of installing a solar system in Mclean can vary by more than $10,000 from home to home. Your actual cost is dependent on several factors. The biggest one is the size of the system your household needs, and other factors include equipment choices, financing options and the solar installer you choose.

Solar Equipment

The cost of solar panel systems varies by thousands of dollars due to a variety of factors. One of the major factors is the system size, which is measured in kilowatts (kW). Solar power systems with better efficiency or power production use better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $2,750. The type of solar panels and equipment you choose is another factor that will considerably impact costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to come at a higher price. Furthermore, solar equipment is more than just the solar panels themselves. You'll also need to make decisions about 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

Most solar installers in Mclean provide solar loans, which reduce the initial cost of installing solar. It's a good idea to factor the interest you'll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and how long it'll take to pay off the loan.

Solar Panel Installation Company

A final factor to keep in mind when trying to figure out the cost of solar for your home or business in Mclean is the company you get to install your solar panel system. As with choosing a company to renovate your kitchen, for example, you'll have no shortage of solar installers that provide a range of services at different price points. Companies that 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 come at a higher cost. It's best to do some research and decide on the company that has the products, warranties and services you want and also is within your budget.

How to Save on Solar Panels

The solar company you go with will affect not only your overall costs, but also the kinds of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are some important things you should keep in mind, such as:

  • Contract: It's important to read through your solar installer's contract well to understand what services they will provide, what the warranty covers and what expectations you should have about the cost.
  • Reputation: Your solar installer should have a solid reputation as a company and have proven expertise in the field. A couple of ways to check this are to look for whether a company has technicians certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it has positive reviews from past customers.
  • Solar Panel Brands: Each solar panel brand and type has varying levels of quality, longevity and energy efficiency. They will come at different price points as well. The company you choose impacts which solar panel brands you have access to.
  • Installation Process: When making the switch to solar power, it's crucial to maintain an open line of communication with your solar panel company. Make sure you understand how the installation process will go and the project completion timeline.

EcoWatch's Mclean, VA Solar Cost FAQs

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

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

Is cost the most important thing to keep in mind when buying solar panels?

Cost is a key factor to consider, but whether it's the most important for you depends on why you decided to go solar. In places where rooftop space is limited, efficiency can trump the cost. Other factors that are important to take into account are the quality and durability of your solar panels.

How much can I save on electricity bills after switching to solar?

It is possible to erase your electricity bills with solar panels, but for most homeowners in Mclean, that will require at least a 10-kW system. Not all homes will have roofs that can accommodate that size system, so you'll want to check with a local solar installer to see how many panels can fit on your roof.

How long do solar panels last in Mclean?

Although the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable at that time. What this means is the amount of energy they produce will have decreased significantly after that point. You can decide to replace them once you've had them for that long or you can keep using them at a lower efficiency.
