How Long Do Solar Installations Take? From Quote to Switch-On
Understanding the Solar Installation Timeline
If you’re thinking about switching to solar, one of the first questions you might have is: how long does the installation actually take? While each project is unique, most residential solar installations follow a clear process — from the initial quote to the moment your system starts generating clean energy.
On average, the entire journey can take four to ten weeks, depending on factors like system size, permits, and weather conditions. Let’s break down each step to give you a better idea of what to expect.
Step 1: Consultation and Quote (1–2 Weeks)
Your solar journey begins with a consultation and site assessment. During this stage, the installer evaluates your roof condition, shading, and energy consumption to design a system tailored to your needs.
You’ll then receive a detailed quote and proposal, outlining costs, expected savings, and recommended equipment. Once you’re happy with the plan and give the go-ahead, the project moves to the next phase.
Step 2: Site Inspection and System Design (1–2 Weeks)
A thorough site inspection is done to finalise measurements and check for structural or electrical considerations. The design team then creates the system layout and ensures it complies with local regulations and your utility provider’s requirements.
This stage is essential for ensuring both safety and performance — a well-designed system means optimal efficiency and long-term reliability.
Step 3: Permits and Approvals (2–4 Weeks)
Before installation begins, your installer must secure the necessary permits and approvals from local authorities and your electricity distributor. This step can take anywhere from two to four weeks, depending on your area’s permitting process.
The good news? Most installers handle all the paperwork for you, so you can simply sit back and wait for approval.
Step 4: Installation Day (1–3 Days)
Once the permits are cleared, it’s time for the exciting part — installation!
For a typical home solar system, installation usually takes one to three days. The crew mounts the panels, connects the inverter, and ensures everything is safely wired. Larger or more complex systems might take slightly longer, especially if additional electrical work is needed.
Step 5: Inspection, Connection, and Switch-On (1–2 Weeks)
After installation, your system undergoes a final inspection to verify that everything meets safety and performance standards. Your utility provider then installs the bi-directional meter and grants approval to connect your system to the grid.
Once you receive the green light, your solar panels are switched on — and you’ll officially start producing your own renewable energy!
The Bottom Line
From your first quote to your first sunny day of energy production, most solar installations take around one to two months to complete. The wait is well worth it — you’ll enjoy lower energy bills, greater energy independence, and the satisfaction of contributing to a cleaner planet.
