Start with the site
Your survey brief should include recent electricity bills, roof ownership, shade, accessible roof area and the electricity connection. Structural condition and safe maintenance access belong in the design from the beginning.
Choose the right architecture
An on-grid system targets daytime generation and electricity-bill reduction. It normally shuts down during a grid outage. Backup requires a suitable hybrid or off-grid arrangement with storage and correctly separated essential loads.
- On-grid: generation with a grid connection.
- Hybrid: compatible solar, storage and backup control.
- Off-grid: engineered for locations without a dependable grid supply.
What a good proposal contains
Ask for equipment model numbers, layout, estimated generation assumptions, protection design, installation scope and a clear exclusions list. Subsidy and export-credit eligibility must be checked against current official rules.
Handover you can use
Request system diagrams, serial numbers, warranty documents, portal ownership, shutdown guidance and a maintenance schedule. Your generation dashboard should help you spot a change in performance.
