Your roof: Vevey
Adapt the project to the building’s use, whether a house, apartment building or business premises. Include future vehicle charging or heating changes in the consumption scenario.
In all cases, the useful surface area is almost always less than the gross surface area announced. Skylights, chimneys, setbacks, shading and future maintenance needs must be integrated before talking about final power.
Measure usable roof area with obstacles and required clearances included. Include the constraints identified during the survey in the quotation.
Exposure and access: Vevey
Request a survey of nearby shading and the horizon, with monthly generation estimates. Compare options for your building using the same weather data and loss assumptions.
Check the simultaneous consumption used to estimate avoided electricity purchases. Value surplus using the confirmed export contract, with guarantees of origin accounted for separately.
Full cost and grants: Vevey
The displayed scenario uses an indicative installed cost for 8 kWp. A quote must specify equipment, roofing and electrical work, connection, inspections and fees before deducting confirmed grants.
Programmes depend on the municipality and available funds. Obtain written confirmation of amounts, timing, limits and combined support for your address before including them in the budget.
Request a technical site survey before relying on a sales estimate. Agree on tests, inspections and documents to be provided at handover.
Output must be assessed for the actual roof, its orientation, shading and condition. Tariffs depend on the grid, product and contract; a cantonal average does not replace your bill.
Building procedures: Vevey
Check building protection and appearance requirements with the relevant authority. Specify fall protection and access for installation and maintenance.
A serious estimate specifies who prepares the announcement, who manages the connection, who follows the administrative back and forth and how any comments are absorbed into the planning.
In the canton of Vaud, distinguish between Pronovo, municipal aid and Buildings Program if solar accompanies a renovation. If this timeline is poorly managed, you lose time and sometimes value on aids.
Reserve space and access for inspections and future replacements. Distinguish avoided purchase costs from the tariff paid for exported surplus.
