Your roof: Meyrin
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.
Define included and excluded work during the technical survey. Record who installs, inspects and supports each part of the system in the contract.
Exposure and access: Meyrin
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.
Measure usable roof area with obstacles and required clearances included. Confirm the supporting structure, anchor points and mounting design.
Full cost and grants: Meyrin
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.
Check the simultaneous consumption used to estimate avoided electricity purchases. Price the necessary electrical distribution board changes and protection devices.
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: Meyrin
Request plans, equipment references and service boundaries before accepting a price. Confirm the supporting structure, anchor points and mounting design.
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 Geneva, check Pronovo, the SIG 2026 solar premium and municipal aid before signing. If the timeline is poorly managed, you lose time and sometimes value on helpers.
Request a technical site survey before relying on a sales estimate. Include the constraints identified during the survey in the quotation.
