Manage multiple roof planes on mobile

A multi-plane project represents several PV surfaces within one installation, such as east and west roof planes and a garage. Each plane retains its own power, area, orientation, tilt and module layout. Consumption, the battery and economics apply to the whole installation.

Use a mobile version that supports multiple planes. An existing single-plane project keeps its usual workflow until you convert it.

A plane and a survey are different

A plane is the surface intended for modules. A survey describes obstacles seen from a measurement point, with the horizon profile, location and available photos. Several planes can share one survey. Adding points to a horizon profile does not create more planes.

Situation	Survey choice
Same viewpoint and surrounding obstacles	Reuse the existing survey. Plane orientations and powers may still differ.
Different viewpoint, measurement height or obstacles	Carry out a new survey from the relevant location.

Sharing a survey is an assumption to check on site. Two planes being on the same building is not sufficient.

Add a plane

Open the project and Overview.
Select the action to add a roof plane.
Choose to reuse the proposed survey or perform a new survey, then continue.
For a new survey, locate the measurement point on the map before capture. Complete the survey from that point.
In the plane settings, enter its name, power or sizing, orientation and tilt. Check proposed values: they are not measurements of the new plane.
Apply the settings and review the installation results.

A cancelled capture or incomplete plane does not provide a complete study. Complete missing data before calculating.

Select the right plane

In the roof-plane list, select the plane name. The plane selector also lets you switch planes. Check the displayed name, orientation, tilt and power before editing.

Sizing, orientation, module layout and height simulation: check the selected plane.
Site consumption, battery, common module selection and economic assumptions: these apply to the whole installation.
Total power is the sum of the plane powers. Do not enter the installation total for every plane.

Shared survey, height and location

The shared-survey indication means that editing this survey affects several planes. Correcting its points or replacing it affects every plane using it. Other surveys remain separate. Read the affected plane names in the replacement confirmation; the validated new capture replaces that shared survey.

A different-height simulation applies to the selected plane. It does not automatically change other planes sharing the survey. Result differences nevertheless compare the whole installation.

The survey location is the observation point, not the centre of each roof. Moving it resets obstacle distances and height simulations for linked planes. Confirming the map without moving the point preserves these data. After an actual move, also check that the horizon profile still represents the new viewpoint.

Scenario mode can test changes to several surveys; differences refer to the whole installation. A scenario is not a new field survey.

Module layout and removal

Each plane has its own layout data. A layout created in the web portal appears on its plane after synchronisation; return to the portal editor to change its modules or obstacles.

To remove a plane, open its settings, choose the removal action and confirm the name. Surveys still used by other planes are retained. Then review total power and the overall cost: removing a plane does not mean that a manually entered overall quote has been adjusted.

Continue at the office

Let synchronisation finish using the same account before opening the project in the portal. Avoid editing the same project on two devices simultaneously.
