Manual panel allocation

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 be unselectable. In this case you may need to add optimisers. 

Without optimisers 

1. Select the current roof and inverter input from the lists on the left.
2. Click or drag over panels to allocate them to an inverter input. 
   
3. Once all inverter inputs have the correct number of panels, all inputs will be in green and a tick will show at the top. Below all your inverters and roofs, you can then click next to continue with the performance task.

With optimisers or microinverters

You can add optimisers in the inverter task by clicking Add optimsers + to the top right of the inverter string. This will automatically add optimisers to all panels on that inverter, if you would like to remove some, this will have to be done manually in the financial task. 

When you then come to allocating the panels the steps are largely similar to non-optimised systems: 

1. Select the current roof and inverter input from the lists on the left.
2. Use the Add group + option to sub-divide the input into shading groups and select the group you want to allocate panels to. You should group panels that will get similar levels of shade or that are on different facing roofs. 
3. Click or drag over panels to allocate them to an inverter input or shading group.
4. Once all inverter inputs have the correct number of panels, all inputs will be in green and a tick will show at the top. Below all your inverters and roofs, you can then click next to continue with the performance task.

Adding optimisers in the inverter task will not automatically change the generation. 
The generation is a product of the kWp of the inverter, the kk value (which is based on the pitch, orientation and location of the panels) and the shading factor. Putting panels in separate shading groups does not correspond to anything physical but allows Easy PV to factor in differences in the kk value and shading factor on the same string. Without shading groups the generation will not change because the kk value and shading factor will be the same on the whole string. as it would be without optimsers. 

Other options

• Use the  icon to reset the allocation on the inverter or individual inverter inputs. 

• Below where it says Next, you also have the option to use auto-stringing. This will not work for systems that require shading groups.
