In Jura, compare contractors using your roof, consumption and project scope. Check authorisations, professional status and written service terms instead of a general ranking.
Check the contractors Request the legal company name, comparable references and the division of work between the main contractor and subcontractors. Check authorisation for the electrical tasks. Swissolar membership and the Solarprofis label are different: verify status and activities in the current directory. Nearby premises guarantee neither competence nor repair response times.
Compare the same project Provide roof details, consumption and required functions. Compare models, layout, monthly generation, included work, exclusions and installed price. A generation forecast is not a contractual guarantee. Specify service costs, warranties and contacts. Request several suitable offers without treating three quotations as a legal requirement.
Define procedures and handover Identify the grid operator for the address and who handles each application. Pronovo provides project-specific procedures and permits third-party representation; check documents and timing. Specify payments, tests, handover records and service in the contract. A supplier name or “all-inclusive” claim cannot allocate every responsibility.
Jura example: assess service for a rented home Consider an owner equipping a tenant-occupied home. This example concerns contract preparation without assuming one arrangement across Jura. Clarify work approval, access and electricity use before comparing prices.
Distinguish who pays the investment, uses the data and can authorise service. Ask how visits are arranged with the occupant. Handing equipment to the owner does not ensure the tenant can understand the app or reach support.
Consider tenant departure, a new energy contract or sale. Who keeps historical data? How is access transferred without leaving former users in control? Define necessary work and charges without assuming installation includes complete rental management.
Compare handover, instructions and proposed annual support. Separate measured generation from billed amounts and request service records. The contract should explain responsibilities for this home; an offer based only on panels or average returns cannot address these operating needs.
