A solar system is installed through six connected stages: a free site survey, custom system design, proposal and agreement, documentation and IESCO paperwork, the physical installation (3-5 days for a typical residential system), and finally commissioning with net-meter activation. Each stage builds on the last, so skipping steps like a proper site survey or documentation usually causes delays later.
Step 1-3: Survey, Design and Agreement
Everything starts with a free site survey, where an engineer assesses your roof, shading, structural condition and electricity consumption. That data feeds into a custom system design sized to your load and roof space. Once you approve the proposal, a formal agreement is signed covering scope, equipment and warranty terms.
Step 4: Documentation and Approvals
Before any equipment goes on the roof, the required NOC and IESCO net-metering paperwork is prepared. Tripower is NEPRA certified and IESCO-approved, so this step is handled on the customer's behalf, including the technical drawings and equipment datasheets that DISCOs require.
Step 5: Physical Installation
The hands-on work follows a set sequence:
- Mounting structure installation on the roof, engineered for local wind and weather conditions.
- Panel mounting and wiring, following the layout from the design stage.
- Inverter installation and connection to the electrical system.
- Safety checks, grounding and cable management.
A typical residential system takes 3-5 days on-site. Larger commercial or industrial systems take longer depending on scale and roof complexity.
Step 6: Commissioning and Handover
Once installed, the system is tested, the bi-directional net meter is activated, and the customer is walked through the monitoring app and basic system operation. From there, ongoing care such as panel cleaning and Annual Maintenance Contracts keeps performance steady over the 25-year panel lifespan.

Frequently Asked Questions
Do I need to be present during installation?
It helps to be available on day one for access and any decisions, but you do not need to be on-site for the full 3-5 days as long as the crew has roof and electrical access.
Is the installation process different for commercial buildings?
The same six stages apply, but commercial and industrial projects involve more detailed load studies, structural checks and longer installation timelines due to system size.
What happens if the site survey finds roof issues?
If shading, structural weakness or space constraints are found, the design team adjusts the system layout or recommends fixes before installation proceeds.
