How the job runs
Eight steps, from the first conversation to the meter
The two that matter most to a buyer are the ones most installers leave off the diagram: the structural check before anything is drilled into the roof, and who handles the utility paperwork.

The installation journey
The eight steps
Nothing is ordered before the written proposal is agreed, and the utility side is ours to run.
Consultation
A conversation about what you are paying now, what you consume during daylight, and what the roof is. Most of what decides whether rooftop solar is worth it is in the first two.
Site and roof survey
The roof is inspected for structure, orientation, shading and access, along with the existing electrical supply and where the system would tie in. This is an engineering visit, not a sales visit.
System design and written proposal
Sizing, layout, the mounting arrangement, the electrical scheme and the price, in writing. Nothing is ordered before this is agreed.
Approvals and net metering application
The application to the distribution utility, and for residential systems the central subsidy application, are prepared and submitted. This is the step that most often decides how long the whole job takes.
Structure and mounting
Mounting structures fabricated and installed to the survey, fixed so that the roof's waterproofing survives the installation.
Electrical installation
Panels, inverter, DC and AC cabling, protection, earthing and lightning protection, and the tie in to your existing distribution.
Testing and commissioning
The installation is tested, then charged and commissioned with the utility's meter in place. You are shown what the system is doing and how to read it.
Handover and maintenance
Documentation handed over, with maintenance support afterwards through the same service engineers who cover the rest of the firm's work.
Step 04 in detail
Six steps with the utility, and who does each
The approvals are the step that most often decides how long the whole job takes. They run in the order the scheme requires.
- Leo files
Application on the national portal and to the DISCOM
Your electricity account, identity and ownership documents, and the bank account the assistance is paid into. Prepared by us, signed by you.
- The DISCOM
Feasibility approval
The utility checks the connection and the load and approves the size. We follow it up until it lands.
- Leo files
Installation by a registered vendor
Structure, panels, inverter, cabling, earthing and lightning protection, to the written proposal.
- Leo files
Net-metering application and inspection request
Filed with the utility once the system is installed, with the test reports.
- The DISCOM
Inspection and the net meter
The utility inspects the installation and installs the net meter. You are present; nothing to file.
- Leo files
Commissioning report and the assistance
The commissioning report goes on the portal; the assistance is released to the bank account you gave in step one.
Where to begin
Start at step 01, the consultation
Tell us what you are paying now and what the roof is. That is enough for us to say whether it is worth surveying.
