Your roof: Bulle
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.
Reserve space and access for inspections and future replacements. Include maintenance, insurance and foreseeable replacements in lifetime cost.
Exposure and access: Bulle
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 the weather assumptions, losses and monthly results behind the stated output. Check how equipment can be accessed and components replaced without damaging the roof covering.
Full cost and grants: Bulle
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.
Use the building’s hourly consumption to size the project. Value surplus using the confirmed export contract, with guarantees of origin accounted for separately.
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: Bulle
Simulate generation and available surplus before choosing a battery. Value surplus using the confirmed export contract, with guarantees of origin accounted for separately.
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.
Prepare a timetable showing procedures, approvals and work in their actual sequence. Agree on tests, inspections and documents to be provided at handover.
