THE SOLAR CADASTRE OF LYON IS ONLINE !
The
solar cadastre allows to know the level of sunshine of each roof, ie the
solar energy received by each square meter of a roof over a given period (in kWh / m² for one year).
The roofs are colored according to their sunshine, with a 6-level gradient ranging from "excellent" to "bad". The solar cadastre also indicates the total amount of energy that can be produced over a year by installing
photovoltaic solar panels (kWh / year).
Produced using
RhinoCity™ the Lyon Metropolis has a very accurate
3D model of its territory: each building, each roof, is modeled.
Thanks to
RhinoSolar™, based on this model and the sun's course for a year, the sun was calculated for each roof section. The visibility of each 3D element present in the model has been taken into account during the calculations. Thus, if a tree, building or urban equipment obscures the sun, it is integrated in the calculation. Only taking into account the
global visibility complex allows the development of a
reliable and
realistic solar cadastre.
