Understand the calculation methods and their limitations

Azimutis results combine site measurements with calculation models. Their interpretation depends on the data and assumptions used.

Horizon profile

A horizon survey records the angular height of the horizon at several azimuths. Azimutis reconstructs a profile that can be used to estimate solar access.

Accuracy depends on the sensors, orientation alignment, measurement position and number of points captured on obstacles.

Irradiation and production

Weather data and solar modeling come from sources including PVGIS. Irradiation is the energy received per unit of area. Production is an estimated amount of electricity based on installed capacity and efficiency/loss assumptions.

Shading losses compare conditions with and without the surveyed obstacles. They do not represent all system losses.

Self-consumption and battery

If no actual consumption series is supplied, the calculation uses a synthetic consumption profile based on annual consumption and the selected usage pattern.

Battery simulations account for usable capacity, storage efficiency, and charging and discharging limits. Automatic capacity sizing seeks an energy-based compromise, which does not necessarily maximize financial returns.

Economic projection

The model uses assumptions including the initial investment, electricity prices, export revenue, maintenance, equipment degradation and replacements. IRR and cumulative balance reflect these assumptions; they are not a contractual guarantee.

Limits of preliminary assessments

The results remain preliminary assessment estimates. They do not replace a building’s structural analysis, detailed electrical design, regulatory checks or validation of a quotation.

When interpreting a result, always compare scenarios based on explicit, consistent assumptions.
