BrightGridA solar installation is a long-term investment, so it is worth checking the project at every stage. This checklist covers the key questions to ask before signing, what to verify during installation and what documentation you should receive after commissioning.
Before requesting a quote
- Collect recent electricity bills.
- Understand annual electricity consumption.
- Identify future EV plans.
- Identify future heat pump plans.
- Check whether the roof has known issues.
- Consider whether battery storage is wanted.
Before accepting the quote
- Confirm the exact panel model.
- Confirm the total kWp capacity.
- Confirm the inverter model.
- Confirm battery capacity if included.
- Review the predicted annual generation.
- Check shading assumptions.
- Check installation scope.
- Check warranties.
- Check payment terms.
- Confirm what happens if additional work is required.
During installation
The installer should follow the agreed design and use suitable mounting, cabling, electrical protection and safety procedures. Any significant design change should be discussed rather than made without explanation.
After installation
- Confirm the system is generating.
- Check the monitoring app.
- Receive electrical certification.
- Receive product documentation.
- Receive warranty information.
- Confirm relevant grid documentation.
- Understand emergency shutdown procedures.
- Know who to contact if the system develops a fault.
| Stage | Key check |
|---|---|
| Survey | Roof, shading and electrical system assessed |
| Design | Panel, inverter and battery configuration confirmed |
| Quote | Complete scope and assumptions documented |
| Installation | Equipment installed according to design |
| Commissioning | System tested and monitoring configured |
| Handover | Documentation and warranties received |
After the installation
Keep an eye on system generation and monitoring. Comparing performance across similar weather periods can help identify unusual changes.
Keep your solar documents
Store your electrical certificates, warranties, equipment information, commissioning records and monitoring details. These can be valuable for future maintenance, upgrades or property sale.
