How Long Does It Take to Install Solar Panels?

Solar panel installation takes at least six hours, but that doesn’t include the planning and permit application you need to accomplish before the contractors can begin their work.

Here are the steps in installing solar panels: 

Choosing a service provider

Before everything else, you have to pick which installers you want. The price and quality of installation differ per company.

Assessing the area

Installers can spend a week checking the size, construction, and condition of your roof, shading, where your roof is facing, etc. They also have to check if your electrical panels need to be upgraded to accommodate the solar panels.

Designing the solar system

Based on the information they gathered, an engineer from the installation company will spend up to three weeks creating a solar system design that fits your needs and conditions. The engineer will consider not only the condition of your house but also the local building and utility requirements. 

Applying for permits

Applying for permits and getting them approved can last between two and seven weeks. However, the installation company will take care of the paperwork, so all you have to do is wait.

Scheduling the installation

Once your municipality signs the papers, the installation company can start scheduling the installation. 

Installing the solar panels

Depending on the area’s size, the job takes six hours to three days.


After the installation, your system must be approved by a local inspector before you can start generating electricity from your solar panels. The inspector will check if the panels are properly installed, if your permits are complete, if the building codes are followed, etc. This can last for one to two weeks.

Utility company approval

For the next two to six weeks, your utility company will conduct its inspection around your property and install an electrical meter before it permits you to operate your panels.

After everything is done, your solar panels will be fully functional. While this may sound like a lot of work, remember that this is an investment that can help you save money in the long run and contribute to a cleaner Earth.
