Factors that Affect Solar Panel Costs in Langley Park

While the average cost of a solar system in Langley Park is $13,517, your final cost may be higher or lower than that. There are many factors that can have a major impact on the cost of a solar panel installation. Below are some of the more important things to keep in mind.

Solar Equipment

The size of the solar energy system you need to offset your energy usage, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, your total will most likely increase by about $3,540. Some solar panel brands — like Maxeon from SunPower — cost more upfront but also tend to offer higher efficiency. In a city like Langley Park, where sunlight is relatively abundant, efficiency can quickly pay off. Plus, if you have a small roof or you don’t have a lot of 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

If paying for solar panels out of pocket is difficult, solar loans are a popular choice because they decrease your upfront costs and allow you to 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 important to take that into consideration as well. You can always lower the total you pay in interest and in some cases even your APR by putting more money down.

Solar Panel Installation Company

The solar company you pick will influence your total cost to adopt solar energy. Different companies will bill different amounts for the equipment and labor.Companies that only sell high-quality, high-efficiency and high-price products — 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 choose a company that provides the products, warranties and services you’re looking for and also fit into your budget.

How to Save on Solar Panels

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

  • Solar Panel Brands: Not all solar companies carry the same brands of solar panels, so the brand and type of panel you want can play a considerable role in the company you choose.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a good reputation and is qualified to get the job done well. Another way you can look into your installer’s reputation is by reading reviews.
  • Contract: Even though reading through a contract can take a lot of time, it’s important to do it fully so you can be sure you understand what services your solar company will provide and the terms of the warranty.
  • Installation Process: One of the most important things 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.
