Factors that Affect Solar Panel Costs in Herndon

Cost is typically one of the most important factors for homeowners who are considering investing in solar. There are a few key factors that will push your cost above or below the average in Herndon: 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

One of the most significant factors to consider when it comes to the cost of going solar is the size of the solar system, which is measured in kilowatts (kW). The more energy your household uses, the larger your system will likely need to be. You can expect to spend around $3,590 per kilowatt in Herndon.The kind of solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you get the most efficient solar panel brands, you’ll end up paying more upfront than if you opted for the most affordable panels. On the other hand, more efficient panels could save you more over time on your energy bills. In addition, extra products, such as solar batteries, can bring your total well above the Herndon average.

Solar Financing Terms

If paying for solar panels in cash is out of reach, solar loans are an affordable route because they cut back your upfront costs and let you pay for your system over five to seven years on average.However, the interest on solar loans also adds to your all-in costs, so it’s vital to keep that in mind as well. You can always reduce the total you pay in interest and sometimes even your APR by making a larger down payment.

Solar Panel Installation Company

The solar installer you hire to handle your switch to green energy can play a role in your total costs. There are about 3 solar installation companies operating in Herndon, and each can charge varying amounts for labor and equipment.Larger national companies typically 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 add-on services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels

The solar company you go with will be a major factor in determining not only your total costs, but also the types of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are some important things you should take into account, such as:

  • Solar Panel Brands: Different companies carry various brands and models of panels. If you know you want a specific brand, make sure the solar installer you’re considering has it.
  • Installation Process: Homeowners should make sure they understand how exactly the installation process will be carried out, as well as important factors like the project timeline.
  • Contract: Before you sign a contract with a solar company, make sure to read it through carefully so you understand the terms. Also, ask questions if you’re unsure about some of the terms, such as what to do if a part breaks or malfunctions and what services you can expect from them.
  • Warranty: Warranties that cover defective panels and repairs over around 25 years are the best you can get in the business, and offering such a warranty is one sign of a quality company.

EcoWatch's Herndon, VA Solar Cost FAQs

How much does it cost to install solar panels in Herndon?

The average cost of solar panels in Herndon is about $17,950 for a 5-kW system and $35,900 for a 10-kW system before the ITC, but the actual cost will depend on stuff such as the model of solar panels you want, what size system you need and how much energy you use.

Should I lease or buy solar panels in Herndon?

Leasing solar panels can be an option if you can’t afford to pay upfront or get a solar loan, but since you don’t own the system, you don’t have access to many solar incentives. Also your home value won’t increase, so you’ll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most bang for your buck from going solar.

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

The majority of states offer net metering programs of some kind. Through these, you can either get paid for the extra power your system generates or or receive credits to put toward future utility bills. Currently there are just three states that don’t have any net metering laws: Alabama, Tennessee and South Dakota.

How often do you have to replace solar panels?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of at that time. What this means is how much energy they produce will have decreased significantly after that point. You can choose to replace them after having them for that long or you can keep using them at a lower efficiency.
