Evaluate a PV offer in a structured way
Compare the described scope of services: modules, inverter, substructure, electrical work, connection, documentation, and, if applicable, storage. Unclear additional services make price comparison difficult.
Ask about responsibilities, qualifications, and how the work is organized. The crucial question is who is responsible for which task. Working with a subcontractor alone is not a measure of quality.
Distinguish between product warranties, performance warranties, and contractual services. Before concluding a contract, clarify which conditions, exclusions, and required documentation apply.
