QUICK ANSWER
Coordinate the roof, electrical equipment and approval responsibilities before ordering. Ask for the assumptions behind energy projections and the written process for changes.
Define the purpose of the upgrade
Distinguish generating electricity, changing major appliances, charging a vehicle and providing selected backup functions. These goals can require different equipment and operating arrangements. Record the household's priorities and available energy-use information without assuming the same package suits every home. Ask which loads a proposed backup system would serve and what happens during an outage. A panel count or battery label is not a complete explanation of how the configuration meets the intended use.
| Decision | What to record |
|---|---|
| Purpose | Generation, new loads and backup expectations |
| Interfaces | Roof, electrical scope and installer responsibilities |
| Approvals | Inspection, utility steps and operation records |
Assess the roof and electrical installation together
Ask qualified professionals to evaluate the roof condition, mounting areas and electrical requirements. Clarify how any roof work will be coordinated before equipment covers the area. Identify the work at the service, panel, wiring and other relevant connections without attempting those checks yourself. A proposal that leaves this entire boundary to someone else can conceal important cost and schedule differences. Record who owns the interfaces between installers, including any restoration and access obligations.
Review projections as assumptions, not promises
Ask which usage, shading, equipment, rates and operating assumptions produce the quoted estimate. Understand whether export, storage or backup capability changes the model. A projected saving is different from a guaranteed household bill. Verify current incentive terms separately with the responsible provider or authority before treating them as money received. Compare equipment and work even when a finance illustration appears attractive; the loan or lease agreement can have obligations distinct from the installation contract.
Plan approvals and documented handover
Identify who handles required permits, inspections and coordination with the utility. Ask which approval the contractor needs before each stage and whether permission to operate is separate from installation completion. Review product availability and the response to a delayed approval. At handover, request the operating demonstration, monitoring access, care information and warranty responsibilities for each component. Keep installation records and the named support contact together so an issue is not passed between businesses without a clear next step.
Common questions
Does a battery automatically power the whole home?
No. Ask which loads and operating conditions the proposed configuration covers. Backup capability depends on the actual design, equipment and connection arrangement.
Should I replace the roof before installing solar?
Have the roof assessed and coordinate any necessary work before equipment is installed. The answer depends on condition and the proposed installation, not roof age alone.
Can I rely on an advertised payback period?
Request the assumptions and verify current financial terms. Actual usage, rates, system performance and eligibility can change the result, so an illustration should not be treated as guaranteed income.
