Your roof: Lausanne
For an apartment building or condominium, clarify roof rights, owner consent and access. Include cable routes, protection and maintenance in the same plan.
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.
Specify the work assigned to subcontractors and who is responsible for each task. Check how equipment can be accessed and components replaced without damaging the roof covering.
Exposure and access: Lausanne
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.
Simulate generation and available surplus before choosing a battery. Specify fall protection and access for installation and maintenance.
Full cost and grants: Lausanne
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.
Assess shifting compatible loads to solar hours before adding storage. Distinguish avoided purchase costs from the tariff paid for exported surplus.
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: Lausanne
Request a technical site survey before relying on a sales estimate. Agree on tests, inspections and documents to be provided at handover.
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.
Specify access, lifting equipment and protection of the work area. Compare mounting and removal arrangements against the condition of the roof covering.
