3MW Roof Mount Design Crashing

[CarlSEL]

Hi, the attached design keeps crashing on the final saving after the shading analysis.

Can you tell us why this is happening, thanks.

Dear Carl,

Thank you for your inquiry.

There is a memory problem, the maximum possible RAM utilisation has been exceeded. Unfortunately, our 3D tool is still a 32-bit process that has a maximum of 1.4 GB of RAM available.

You can try unchecking the ‘Backup copy’ box in the 3D tool under ‘Options’.

If the simulation is still not possible, we recommend that you

• divide the entire system into subsystems
• perform the shadow simulation for each subsystem individually and
• simulate the entire system only without shadow simulation.

Thank you, how do I perform the shadow simulation for each subsystem individually?

Dear Carl,

Thank you for your inquiry.

Create three copies of your project file, one for each roof. In the first file, delete all PV modules on roofs 2 and 3. Then carry out the shadow simulation for roof 1 only. Proceed in the same way for roofs 2 and 3.

Yes but how will i get accurate production figures with the HHD utilised when it is spread across the 3no elevations?

How would I work out the self sufficiency and own consumption?

 

Thanks

You divide your system into sub-projects and simulate them separately in 3D. You will then receive a value for the "yield reduction due to shading” in the results. You can take screenshots within the 3D visualization, which you then add to the presentation of the 2D planning after Word export. 

You then plan the complete system in 2D. There you can plan with up to 100,000 modules per module area, whereby the number of module areas is unlimited. To take shading into account, you enter the value of the "Yield reduction due to shading” from the 3D planning as a percentage value under Shading in the 2D planning.

Thank You!
