Step-by-Step Guide to Installing Solar Panels: The Complete Process

Switching to solar energy is an excellent choice for businesses looking to reduce energy costs and embrace sustainability. However, the journey from deciding to install solar panels to having them fully operational involves several key stages. Below, we break down the process of installing commercial solar panels, from feasibility studies to the final handover.

1. Feasibility Study Agreed

The first step in any commercial solar installation is agreeing on the feasibility study. This phase ensures that installing solar is a viable option for your business. A team of experts will evaluate your current energy consumption, location, roof structure, and financial goals. If everything aligns, you’ll receive a report outlining the solar potential and the expected return on investment (ROI).

2. Feasibility Preparation Stage

Once the feasibility study is agreed upon, the preparation stage begins. This involves gathering all necessary information to proceed with the project, including detailed plans for the roof and a comprehensive review of any potential obstacles, such as nearby shading or electrical system compatibility. During this stage, the project team will design a tailored solution that maximizes your building’s solar potential while considering budget and operational needs.

3. Feasibility Survey Stage

The next step is the feasibility survey. During this phase, a professional surveyor will assess your roof’s structural integrity, access points, and available space for solar panels. The survey will also check the energy grid’s capability to accommodate the solar energy system. By conducting this thorough review, the survey team ensures that the system will be both efficient and safe when installed.

4. Feasibility Complete

After the feasibility survey, all necessary approvals and final calculations will be completed. At this stage, you’ll receive the go-ahead to move forward with the installation. The system design will be finalised, and all permits required for construction will be arranged. You will also have a clear timeline for when the installation can begin and how long the process will take.

5. Commercial Solar Installation

Once all the preparations are complete, the installation process begins. Professional solar panel installers will work efficiently to mount the panels on your roof, connect them to the power system, and set up any additional components, such as inverters and battery storage, if required. This process can take anywhere from a few days to a few weeks, depending on the size and complexity of the system.

6. Commercial Solar PV Handover

After installation is complete, the final step is the handover of the commercial solar PV system. During this stage, the system is thoroughly tested to ensure that everything is operating correctly and efficiently. A team member will walk you through the system’s operations, provide training on how to monitor performance, and answer any final questions. Once everything is in place, you’ll be ready to start enjoying the benefits of your new solar energy system.


The process of installing commercial solar panels involves several key steps to ensure that your system is properly designed, installed, and integrated. From feasibility studies to the final handover, each phase is crucial to making sure that the solar system is efficient, reliable, and tailored to your business’s needs. By understanding this process, you can confidently make the transition to clean, renewable energy.
