- Audit and measurements: site and roof survey, determination of potential capacity and optimum panel configuration.
- Technical design: calculation of number and location of panels, inverter selection, tilt angle and mounting system.

- Marking of the site (for ground-mounted installations) or roof survey (for industrial and private roofs).
- Strengthening the base: installing the necessary foundations, posts or reinforcing the rafter system (if necessary).

- Installation of supporting structures: installation of frames or supports for floor systems, installation of steel rails for roofs.
- Installation of fasteners: fixing of rails or panel brackets to the roof slope or to the prepared structure.

- Fixing the panels: placing the modules on the installed rails or supports.
- Connecting the modules: wiring between the panels according to the diagram (series or parallel connection).

- Inverter: site selection and installation (indoors or outdoors in a protected enclosure).
- Switchboards, meters: installation and connection of energy metering and system protection devices.

- Cable routing: laying cables from the inverter to the electrical panel (or transformer station on large sites).
- Grid connection: approval by the power company and introduction into the general electrical grid or stand-alone system.
- Verification and adjustment: testing of each component, control devices and the correct functioning of the system.

- Documentation: preparation and signing of commissioning certificates, obtaining authorisations (if necessary).
- Final testing: verification of power output and stability of operation.
- User training: explanation of the rules of operation, monitoring and maintenance.
