Sunlight is a source of affordable, reliable, and clean energy. Solar photovoltaic (PV) installers or solar panel installers specialize in installing solar panels for residential and commercial applications.


A solar PV system consists of solar panels with photovoltaic cells that convert sunlight (solar radiation) into direct current electricity. Residential and commercial solar panels help access clean technology, achieve energy independence and security, as well as reduce carbon footprint and utility expenses.  


When it comes to taking control of rising energy costs and bringing a distributed, renewable energy solution within reach of residential and commercial customers, solar panel installers have been making the transition to solar easier with 100% peace of mind. 


Read on to learn more about the top 10 U.S. solar panel installers turning sunlight into savings and sustainable energy.

Who is a Solar Panel Installer?




A PV installation professional or a solar panel installer assembles, installs, and maintains a wide range of solar photovoltaic systems on roofs and other structures with adherence to site assessment and schematics.


The person should be comfortable working on roofs for extended periods of time and have carpentry, electrical work, and other required skills along with solar installation experience.


Solar installation involves ascending and descending ladders, bending, crouching, kneeling, etc., and working in all weather conditions, with a good mechanical skillset and a sense of balance.


Furthermore, a solar installation company has a variety of safety policies regarding protective equipment, fall protection, tailgate training, and more in place to ensure worker safety.


Most installers have a solar PV certification from the North American Board of Certified Energy Practitioners® (NABCEP®).


A certified energy practitioner can have a rewarding career in the solar industry, with several roles like a PV design technician, PV installer specialist, PV commissioning & maintenance specialist, PV system inspector, and solar energy installation manager.


Top 10 Solar Panel Installers in the United States

Here are the top 10 solar panel installers in the United States (ranking based on capacity installed):

Sunrun Inc.

Founded: 2007

Location: San Francisco, California




Sunrun is a leading U.S. residential solar and energy storage company that provides quality solar products and services for homeowners’ unique energy profiles and solar electricity needs.


The company’s installation crews come with 20+ years of installation experience, and the available residential solar plans include monthly solar lease, full amount solar lease, monthly solar loan, and full purchase.


Sunrun Installation Process

  • Conduct a site survey to check the attic, electrical panel, and roof
  • Finalize a custom design
  • Apply for permits
  • Collect other essential approvals (such as HOA approval) and documents


Here, a home solar system consists of solar panels, an inverter, and a Sunrun meter to measure and monitor solar production. In addition, the main electrical panel or “fuse box” and the utility meter already at home are connected to the solar system.


Moreover, Sunrun’s Brightbox enables solar customers to benefit from solar battery storage and have power when they need it most.


The residential solar electricity company offers custom solar designs (using Sunrun’s Automated Site Modeling tool), a comprehensive insurance policy, and a bumper-to-bumper solar system warranty, which includes free solar equipment replacement and system repairs.
