Manual panel allocation

Panels can be manually allocated in the Performance task. Whether a project requires manual allocation depends on it's complexity, it's size and whether the system is optimised. After a system has been automatically allocated, you may also wish to make edits to the string arrangement. 

Manual panel allocation

To open up the manual panel allocation, follow these steps:

  1. Open the Performance task
  2. Click Edit inputs in the top right
  3. Select the Panel allocation tab
  4. Then click Edit allocation or Allocate panels in the bottom left

Manually allocating panels is slightly different depending on whether the panels are optimised or not. All panels connected to an input must be within a certain pitch and orientation threshold and panels incompatible with the selected string will not be selectable. In this case the panels may need to be optimised. 

With non-optimised systems 

  1. Select inverter input and the roof you'd like to allocate from the list on the left
  2. Click or drag over panels to allocate them to an inverter input
  3. Repeat steps 1-2 on the next inverter input or roof until all panels are allocated. All inputs will be in green and a tick will show at the top of the page
  4. Below all your inverters and roofs, you can then click Next to continue with the Performance task

With optimised systems 

WhenWere optimisers are required (panels are on the same string but different pitch or orientation) Easy PV will not let you comeallocate tothem allocatingon the panelssame string. You must instead sub-divide the string into shading groups. These steps are largelyoutlined similar to non-optimised systems: below:

  1. Select inverter input and the roof you'd like to allocate from the list on the left
  2. Click or drag over panels to allocate them to an inverter input 
  3. If you are allocating panels to the same MPPT on a different roof click  Add group + to sub-divide the input into shading groups and then select the roof and allocate the panels
  4. Repeat step 3 on the next inverter input, shading group or roof until all panels are allocated. All inputs will be in green and a tick will show at the top of the page
  5. Below all your inverters and roofs, you can then click Next to continue with the Performance task

Tip: You do not need to put each individual panel into a shading group. To best model the output of the system, group panels that will get similar levels of shade. Easy PV will also require that you use shading groups for panels that are on different facing roofs but on the same string.

Other options

  • Use the Screenshot from 2025-02-11 11-29-13.png icon to reset the allocation on the inverter or individual inverter inputs

  • Below where it says Next, you also have the option to click Auto-string. This will not be available for all systems
