What to Expect During a Solar Panel Installation
Installing solar panels is usually a straightforward process, but many homeowners want to understand what will happen before work begins.
Most residential solar installations are completed within a few days. The exact process depends on the system size, roof type, and whether battery storage is included.
This guide explains the typical stages involved when installing a solar PV system.

1) Initial Discussion
The process begins with an initial conversation about the property and its suitability for a solar panel installation.
We discuss the type of property, the roof layout and orientation, and the property’s typical electricity usage. We may also talk about whether battery storage could be beneficial.
This information allows us to determine whether solar panels are likely to be suitable and what size system might work best for the property.
2) Provisional Design Proposal & Cost Estimation
Using the information provided to us, we can provide an initial cost estimate, including calculations of the system’s payback period and the amount of electricity likely to be generated annually.
This proposal outlines the recommended number of solar panels, the expected system output, and the equipment to be installed. It may also include optional battery storage if this has been discussed.
If the project moves forward, the next step is a survey of the property.
3) System Design Proposal and Quote 2) Property Survey and System Design
During the survey, we will clarify any assumptions that were made during the initial cost estimate. We assess the roof structure, available roof space, and orientation to determine where solar panels can be installed. We also review the electrical setup within the property and identify suitable locations for the inverter and battery, if included.
After the survey, a final system design and quotation is prepared and presented to the customer. At this stage, customers can review the proposal and decide whether to proceed with installation.
4) Installing the Solar Panels
Once installation begins, the first stage is usually preparing the roof for the solar panels.
Scaffolding may be installed to allow safe access to the roof. The mounting system is then attached to the roof structure before the solar panels are secured. These mounting systems are designed to securely hold the panels while maintaining the roof’s weatherproofing.
5) Electrical Installation
Once the panels are in place, the electrical components are installed.
This usually involves installing the inverter inside the property and connecting it to the roof-mounted solar panels. The inverter converts the electricity generated by the panels into a form usable within the building.
If the system includes battery storage, the battery is typically installed at this stage, often in a garage, utility room, or another suitable location.
6) System Testing and Commissioning
After installation, the system is tested to ensure everything is operating correctly.
This includes checking the electrical connections, confirming the system is generating electricity, and setting up monitoring if the system includes it. Customers are also shown how the system works and how they can view their energy generation.
Frequently Asked Questions
Most residential solar installations are completed within a few days. Larger systems or installations that include battery storage may take slightly longer, but the process is generally quick compared with many other home improvement projects.
In most cases, disruption is minimal. Much of the installation work takes place on the roof or outside the property. Inside the property, work is usually limited to installing the inverter and connecting the system to the electrical supply.
Solar Panels Designed for Your Property
Every property is different, which is why solar systems are designed around the building and the customer’s electricity usage.
By assessing the roof, electrical system, and available space first, it is possible to design a solar installation that works efficiently for the property.
