A solar proposal is easier to evaluate when it connects the household's electricity use with the site's physical conditions, equipment details, and the full cost of the project.
- Prepare recent electricity bills and a list of your goals.
- Compare like-for-like equipment and installation scope.
- Get warranty, approval, and after-sales responsibilities in writing.
Understand your electricity use
Keep recent electricity bills available and note any major changes in daily usage. This gives the installer a useful starting point for sizing and discussing expected generation.
Ask about site assessment
Roof area, orientation, shade, structural condition, wiring, and local conditions can affect a project's design. Request a site assessment rather than relying only on a generic estimate.
Compare the complete proposal
Check the panel and inverter specifications, mounting and installation scope, safety protections, monitoring, warranty terms, maintenance, and what is excluded from the quoted price.
Confirm approvals and service
Ask who is responsible for applicable utility approvals, metering, or incentive paperwork, and which documents you will receive at handover. Availability and requirements can vary by location and project type.
