What Impacts the Time to Install Commercial Solar? 

If you’re considering switching to solar power for your business, you’re probably wondering how long the installation process will take. There are many factors that will influence the time it takes to install a commercial solar PV system: 

  1. The first thing that will affect the timeline for your solar panel installation is the size of your system. A smaller system will obviously take less time to install than a larger one. 
  2. The second thing is the type of roof you have. If you have a flat roof, the installation process will be quicker than with a pitched roof. 
  3. The third factor is whether or not your roof needs to be replaced. If it does, that work will need to be completed before the solar panels can be installed. 
  4. And finally, the fourth thing that will impact the timeline for your project is the number of people working on the installation. Obviously, the more people you have working, the quicker the job will get done. 

So there you have it—a quick overview of the main factors affecting how long it takes to install commercial solar panels at your business.

The Commercial Solar Installation Process 

Here is a step-by-step guide on what you can expect during the installation process:

  1. Site assessment – The first step is to schedule a site assessment with a qualified solar installer. This assessment will help determine if your business’s location is suitable for solar panel installation. Factors that will be considered include the angle of your roof, the amount of sunlight that hits your property, and any shading from trees or buildings. 
  1. Proposal – Once that’s been determined, a custom proposal for your project is created. This gives you an outline of the project cost, timeline, expected ROI and the best commercial solar panel for your business. 
  1. Project approval – Once you’ve decided to move forward with the project, the next step is to get approval from your local council. This usually involves submitting an application and getting a permit. Depending on your location, this process can take anywhere from a few weeks to several months. 
  1. Ordering of components – The ordering process for your panels and components usually takes roughly 2-4 weeks, depending on availability. Once everything has been delivered to our warehouse, we’ll schedule a time for installation. 
  1. Final site assessment – Once all the relevant permits have been obtained, the solar panel installer will conduct a final site assessment to determine the best placement for your panels.
  1. Installation begins – Once you have approval, the installation process can begin. This usually takes 1-2 weeks, depending on the size and scope of the project, though complex installations may take up to 4 weeks. 
  1. Brackets mounted on the roof – Once the placement has been determined, the installer will begin mounting the brackets that will hold your solar panels in place. 
  1. Solar panels & inverter installed – After the brackets have been mounted, the solar panels will be attached and connected to an electrical inverter. 
  1. Mains power connection – Finally, your solar system will be connected to the mains power supply and switched on. And that’s it! You’re now generating renewable energy and saving money on your energy bills. 
  1. Monitoring – After your commercial solar panels are up and running, monitoring their performance regularly is important. This can help ensure that they’re operating as efficiently as possible and spot any potential problems early on.


Installing commercial solar panels is a big investment that can pay off for your business in the long run, especially when paired with commercial solar batteries. If you’re thinking about switching to solar power for your business, hopefully this overview has given you a better understanding of what’s involved in the process. 

From site assessments and permit applications to installation and monitoring, there are plenty of things to keep in mind—but with careful planning, it can all come together seamlessly.
