The Solar Installation Process
Knowing the steps helps you plan timelines and spot shortcuts. Here is how a well-run project proceeds.
Before installation
- Initial consultation
- Electricity bill analysis
- Site assessment
- System design and component selection
- Cost estimation and written proposal
- Subsidy and documentation guidance
Installation and commissioning
- Structure and panel installation
- Electrical work and safety checks
- Grid synchronisation and commissioning where applicable
- Handover, monitoring setup and training
After installation
Monitor generation, schedule cleaning and keep warranty documents. Plan periodic inspections or an AMC.
EPC explained
EPC stands for Engineering, Procurement and Construction. One provider designs the plant, buys equipment and builds it, then supports testing, commissioning, operation and maintenance.
Questions to ask at each stage
- At assessment: what shading analysis will you do and how?
- At design: why this inverter and panel combination for my roof?
- At installation: who supervises the work and what safety measures are used?
- At commissioning: what tests are performed and recorded?
- At handover: what training and documents do I receive?
