Should every model be named?
Named equipment makes a proposal easier to review. Ask for the panel, inverter and other relevant specifications rather than comparing an unexplained system label.
Are warranties identical across brands?
No. Terms can differ by model and provider. Review the actual documents, exclusions and responsibilities for the equipment in the proposal.
Can a cheaper panel change total project cost?
It can affect only one part of the amount. Compare inverter, mounting, wiring, installation and site work alongside panel cost to understand the whole scope.
What should the complete proposal include?
Request named equipment, capacity assumptions and the physical installation work. Mounting, wiring, site tasks, responsibilities, approvals context, warranty documents and exclusions should be clear in the proposal.
Can we discuss the property before choosing equipment?
Yes. Start with equipment models, installation scope and warranty information, recent electricity information and relevant site photographs. Equipment should be considered within the property-specific project rather than chosen before the requirement is understood.
