What Impacts the Time to Install Commercial Solar?

When considering the installation of commercial solar panels for your business, you’re likely interested in understanding the timeline for the process. Several factors come into play that can influence the duration of a commercial solar PV system installation:

  • System Size: The size of your solar system is a primary determinant. Smaller systems naturally require less time for installation compared to larger ones.
  • Roof Type: The type of roof you have also plays a role. Flat roofs typically facilitate a quicker installation process in contrast to pitched roofs.
  • Roof Condition: Another significant factor is the condition of your roof. If your roof requires replacement or repairs, this work must be completed before the solar panels can be installed.
  • Workforce: The number of individuals involved in the installation process matters. Naturally, having more workers on the project leads to a faster completion.

In summary, these are the key factors that impact the timeline for installing commercial solar panels at your business.

The Commercial Solar Installation Process

Here is a step-by-step guide outlining what you can expect during the commercial solar panel installation process:

Site Assessment:

  • Initiate a site assessment with a qualified solar installer.
  • Evaluate the suitability of your business location for solar panel installation.
  • Consider factors such as roof angle, sunlight exposure, shading, roof condition, and electrical panel capacity.
  • Collect HOA paperwork and note any required repairs or adjustments.
  • Sign a contract within a few days to a week after the assessment if everything is in order.


  • Create a custom proposal for your project, outlining project cost, timeline, expected ROI, and the recommended commercial solar panel.
  • Begin the permit application process, which can take around four weeks, subject to local building department approval.
  • Secure permits, including Solar PV and Electrical Permits, which can vary in processing time but may take several weeks to months.

Project Approval:

  • Seek approval from your local council by submitting an application and obtaining necessary permits.
  • The approval process timeline varies based on location, ranging from weeks to months.
  • After solar panel installation, a building inspector conducts safety checks, and upon approval, you receive a certificate of occupancy, typically within a week but subject to inspector availability.

Ordering of Components:

  • The ordering process for panels and components usually takes 2-4 weeks, depending on availability.
  • Schedule installation after all components have been delivered to the warehouse.

Final Site Assessment:

Conduct a final site assessment to determine optimal panel placement once all permits are secured.

Installation Begins:

  • Begin the installation process, typically lasting 1-2 weeks, with larger projects possibly taking up to 4 weeks.
  • Residential systems usually take one day, while larger commercial installations may require up to five days.
  • The process is generally quick, with minimal monitoring required, except for occasional access needs for equipment installation.

Brackets Mounted on the Roof:

  • Install brackets to secure the solar panels in place.

Solar Panels & Inverter Installed:

  • Attach the solar panels to the mounted brackets and connect them to an electrical inverter.

Mains Power Connection:

  • Connect the solar system to the mains power supply and activate it.
  • Your business is now generating renewable energy and reducing energy costs.


  • Regularly monitor the performance of your commercial solar panels to ensure efficiency and identify potential issues early on.
  • Following installation, a building inspector conducts safety checks, and upon approval, you receive a certificate of occupancy, typically within a week, subject to the inspector’s schedule.

This comprehensive process outlines the steps involved in installing commercial solar panels for your business.
