Your roof: Fribourg
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.
Check the simultaneous consumption used to estimate avoided electricity purchases. Agree on tests, inspections and documents to be provided at handover.
Exposure and access: Fribourg
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.
Request a technical site survey before relying on a sales estimate. Compare mounting and removal arrangements against the condition of the roof covering.
Full cost and grants: Fribourg
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.
Reserve space and access for inspections and future replacements. Record amounts, deadlines and revision terms in the offer.
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: Fribourg
Compare quotation items for the same scope of work and supply. Keep the simulation assumptions so results can be compared after commissioning.
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.
Request the weather assumptions, losses and monthly results behind the stated output. Confirm voltages, currents and module compatibility with the selected inverter.
