Factors that Affect Solar Panel Costs in Herndon

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

Solar Equipment

The cost of solar panels varies by thousands of dollars due to some different factors. One of the main factors is the system size, which is measured in kilowatts (kW). Solar power systems that have greater efficiency or power generation 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 kind of solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you opt for 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, add-on products, like solar batteries, can bring your total well above the Herndon average.

Solar Financing Terms

Most solar companies in Herndon provide solar loans, which reduce your upfront costs of installing solar. Although solar loans make switching to solar energy more accessible for Herndon homeowners, they can also increase the total you pay for your system, depending on your interest rate. If you put down a larger down payment, though, you can cut back on how much interest you have to pay.

Solar Panel Installation Company

Finally, the company you get to install your solar panels can impact your pricing. Herndon's solar companies all have different labor costs and add varying upcharges to equipment. Additionally, some companies in Herndon know more about local solar incentives and can help you take advantage of additional rebates or tax exemptions. However, they may charge more for walking you through the whole process. Even if they cost more upfront, they could end up saving you more money in the long run.

How to Save on Solar Panels

There are a lot of companies to choose from in Herndon, and some homeowners feel overwhelmed considering their options. Selecting the right company for you can be tough, so here are some tips to help you decide:

  • Contract: It's important to look over your solar installer's contract closely to understand what services they will provide, what the warranty covers and what you can expect about the project timeline.
  • Solar Panel Brands: Not all solar installers have the same brands of solar panels, so the brand and type of panel you want can play a big role in the company you go with.
  • Reputation: Long-standing companies likely have a high reputation. This is important because it ensures that it will not only see your solar project through, but will also provide quality aftercare and customer service, such as part repairs and replacements.
  • Installation Process: Get details from your solar company about the installation process and what to expect, such as when the site survey will be completed and what the project timeline is.
