Your roof: Morat
For a detached house, check roof condition, shading and electrical capacity before signing. A single owner’s decision still requires a technical roof survey.
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. Distinguish avoided purchase costs from the tariff paid for exported surplus.
Exposure and access: Morat
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. Keep the simulation assumptions so results can be compared after commissioning.
Full cost and grants: Morat
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. Identify the service contact and stated response times after commissioning.
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: Morat
Request a technical site survey before relying on a sales estimate. Record amounts, deadlines and revision terms in the offer.
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 Fribourg, photovoltaics go through Pronovo; cantonal aid mainly concerns solar thermal, renovation or the Buildings Program. Verify any local support before including it in the budget.
Specify access, lifting equipment and protection of the work area. Confirm voltages, currents and module compatibility with the selected inverter.
