1. Choose a map or upload an image
Use the default map, or select another. See Map Integrations for all the options.
If using NearMap and MetroMaps, you can also select historical maps - click on the cog icon at the bottom right of the screen
Upload building plans, drone images, or other online map images.
You can change your default map settings in your User Profile
2. Draw roof surfaces and layout the grid
Select the Add Surface tool.
Starting at the gutter, click on all the corners of the roof face, and double click to complete.
The first line you draw is the base length, or lowest edge of the surface, and determines which way the panels will tilt, aka the azimuth. You can change it by selecting the Set Base Length tool.
To adjust the shape of the surface:
Double click on the surface border to select the surface.
Click once more to enter surface edit mode
Select and drag the circles.
Measure the edge of the surface by hovering your mouse over the edge.
To move the entire surface
Click once on the edge of the surface or select the surface edit tool.
Click and hold your mouse button down and move your mouse.
Adjust the panel grid
The grid shows the possible locations to place panels. In the Surface Settings section you can adjust it in the following ways:
Adjust the surface pitch (a)
The default is 23deg for residential and 3deg for commercial - you can change the default in your User Profile.
If designing a ground mount, the surface pitch is the slope of the land.
Rotate the panels from portrait to landscape
Select the Edit Layout tool
Click on the Rotate icon
You can zoom in and rotate each row separately.
Add gaps or spaces between rows (d)
Enter a measurement in the Row Spacing field
Move a row across half a panel
Select the 50% Second row offset option
Create blocks of panels
Enter the number of rows grouped together (in this example, there are 5)
Enter the number of columns grouped together (in this example, 3)
Enter the Aisle spacing in mm.
Add tilt frames
In Array Designer, click on Balance of System icon
Change Mounting Type to Tilt Frame
Enter Tilt Angle
Auto calculate row spacing, so panels don’t shade the row behind.
Add tilt frames as per instructions above
In Surface Settings, you will now be able to select the Winter unshaded period (10-2pm or 9-3pm).
Click Apply row spacing
Note the calculated row/aisle spacing.
You can also mount 2 rows together as shown
Click Apply row spacing after any adjustments to re-calculate the row/aisle spacing
Ground mount
See tools above for tilt frames and auto calculating row spacing.
The surface pitch is the pitch of the ground.
East/West or Back-to-back
Create 2 identical surfaces, one facing east, the other facing west
Set the Row Spacing at 1300mm or as required.
Set the Surface pitch to 0
In Array Settings > Balance of System, set the tilt angle.
Click once on the edge of a surface to select the surface. Then click, hold, and move your mouse to move the surface on top of the other. Zoom in to fine-tune the alignment. When creating the surfaces, first create one, then create the second by tracing the first to get them equal dimensions.
3. Select an inverter and panels, or a pre-build package
Recommended System Size
The kW Solar recommendation is aimed at matching the average solar production with the customer’s average consumption. It is a simple guide only, based on the consumption profile loaded, the peak sun hours for that latitude, and an average system efficiency of 80%. It doesn't take into consideration battery size.
The kWh Storage recommendation is based on simple hours of autonomy. In other words, for the given consumption profile, if you want 8 hours of autonomy, then use a 10kWh battery. It doesn't take into consideration the energy from the solar array.
a) Either select a pre-build package
In the packages section, there is a Quick Guide with suggested system size based on the information you entered on the Energy page.
The suggested sized is based on maximising self-consumption of solar power, with a view to having a battery now or in the future.
or
b) Select an inverter and module combination
Enter the inverter and panel names
Choose how many strings per MPPT, and how many panels per string.
You can see how many MPPTs the inverter has, the possible number of parallel strings, and possible modules per string.
The allowable string configuration is calculated based on:
the power, current and voltage ratings of the inverter and modules
the site temperature stats
design Standards (eg limit residential voltages to 600V, inverter 75% oversizing, 1.25 current multiplier) which can be adjusted in Business Settings.
Don’t worry about locking in a string configuration at this stage, you can change it later. Just make a selection and click Save
4. Place panels on the roof
There are a few ways you can do this.
a) Place panels one MPPT at a time.
Click the Drop to Surface icon for MPPT1
Click and swipe your mouse across surface grid where you want the panels to go
When the number of panels in the electrical design matches the number selected on the roof, the box will go green.
If you add too many panels, the box will go red
If you don’t add enough, the box will be grey.
You can adjust the electrical design to suit the roof layout.

b) Place all the panels from an inverter at once.
Click on the inverter icon, hold, drag and drop the icon onto the surface
c) Place panels one-by-one.
Instead of swiping your mouse across multiple panels, you can click them one-by-one.
d) Auto-fill and re-string.
For large systems, you can click Fill to fill the entire roof.
You can then see how many panels will fit on the roof.
Select your inverter and panel combination
Now click re-string to allocate the panels on the roof to the strings in your electrical design.
Swipe across the unwanted panels to delete them.

Panel Layout for a System Upgrade
Create a separate surface for any existing array in order to separate it from the new panel layout.
Note: to set an array as existing, move to the System Designer (with battery) view, then open the tracker panel to set each tracker as an existing array (and any inverter as pre-existing).
