Hva dette ikke sier
Gjengitt ordrett fra seksjonens warnings-felt, slik API-et returnerer det. Vi oversetter dem ikke: en oversettelse ville vist noe annet enn det svaret ditt faktisk inneholder.
- Estimate, not a quote, a site survey or a production guarantee: roof planes found in the 1 m surface model, irradiance from NVE's 1991-2020 map, standard assumptions for losses and usable area (assumptions lists every one).
- Roof planes: DOM1/DTM1 pixels inside the matrikkel footprint and at least 2 m above the terrain, grouped as flat or by facing into eight sectors, each with a least-squares plane (pitch_deg, azimuth_deg clockwise from north). Irradiance: NVE Solressurser global horizontal irradiance per season, split 50/50 into beam and diffuse and transposed to each plane; beam is zero while the sun is behind the horizon profile (roof level, computed with the sun_hours horizon code on DOM1 and on a 6 km terrain tile). kwh_per_kwp = irradiance on the plane x 0.80 performance ratio. Planes under 600 kWh/kWp or steeper than 60 degrees get no modules; usable area is 60 % of a pitched plane and 40 % of a flat roof (modules then assumed tilted 10 degrees south); 0.20 kWp per m2.
- annual_value_nok assumes half the production is used in the house (saving the spot price and the grid company's energy charge incl. levies) and half exported at spot (12-month mean in the price area). No subsidy, supplier margin or fixed-charge effect. payback_years is null unless an installation cost per kWp was set for the run (install_cost_nok_per_kwp_assumed): no installation price is invented.
- 1 m surface data resolves the main roof planes only: dormers, chimneys, roof windows, snow cover and roof condition are not seen. Trees are shading as captured in the surface model's survey year. The validation block compares the best plane's yield with PVGIS (EU JRC), another model, not measured production.
- Sources: NVE Solressurser (licence not stated by NVE; collection is disabled until it is confirmed), Kartverket DOM1/DTM1 (CC BY 4.0), matrikkel footprint (Kartverket Matrikkel, by agreement), energy prices and NVE grid tariffs. Model: Approach.
