Factors That Affect How Long It Takes to Install Solar Panels

To determine how long it takes to have a solar panel installed, it’s important to learn the factors that can affect it. These include the following:


The installation of solar panels can be a lengthy process and will depend on the size of the system and the complexity of the project. To install a small residential solar system, it typically takes one to three days.

However, measurements for larger commercial or industrial projects may take an additional day or two. On average, measurements and installation of a full solar power system require up to five days.

Before installation begins, it is essential to ensure the panels are correctly sized for the area. This will minimize mistakes and delays during the installation process.

Layout of the System

The process of installing solar panels includes designing and laying out the system. Initially, layout is the most important step, as the efficiency of the system depends on the positioning of the individual panels. The layout requires the most time and attention, and depending on the size and complexity of a system, it can take anywhere from three to seven days.

Creating the layout also involves bird proofing solar panels. This means putting protective guards around each panel or covering the entire system with protective mesh netting. While it adds an additional step, it’s a crucial step to ensure your solar panels remain in good condition.

The Skill Level of the Installer

Experienced installers can install an average solar system in one to two days. This could involve 10 to 14 hours of run time per day. On the other hand, novice installers may take up to four days to comprehend their panel layout and understand how to attach the panels correctly.


The length of time it takes to get permits for solar panel installation can vary from region to region. In some areas, permits are granted instantaneously. Meanwhile, in others, it may take several weeks before a permit is issued.

In general, if the paperwork is filled out completely and accurately, the permitting process should take around 2-4 weeks. As the complexity of the system increases, so does the amount of time it takes to get the necessary permits.

Once all the paperwork has been taken care of, the solar panel maintenance installation can begin. All of the panels should typically be in place and operational within 1-2 weeks.

Understanding How Long Does It Take to Install Solar Panels
