Equipment

What types of modules do you allow?

Where can I upload my equipment?

Where can I upload my trackers?

How do I configure agriPV?

In terms of energy calculation, what inverter power does the software use?

Can I limit the inverter’s power? How?

Why does my structure say that it’s only designed for “monofacial”?

Which inputs will affect the recommended number of modules per string?

Why can’t I increase the number of strings per structure?

Can I combine different sizes of trackers together in the same design?

Can I have a different type of structure in each area? If not, can you propose me an intermediary solution?

What things does the “minimum ground clearance” affect?

Is RatedPower considering a derating due to temperature & altitude at the inverter level?

Why is the number of modules per string highlighted in orange?

What does the service type mean? Does it change anything?

How do I set my power station transformer’s capacity?

What transformer manufacturers do you work with or have in your database?

I need to use specific skid station sizes. How can I do so?

What’s the ridge distance?

How’s the default tilt angle calculated?

Layout

Why do I have red structures in my layout? How can I change that?

How can I set the total number of inverters?

I put 30 MWac in “Specific capacity” but only got 18 MWac in my design. Why?

It seems that RatedPower is calculating the AC capacity wrong. If you multiply the number of inverters by the capacity of one, it should be different.

Where can I limit how much energy my plant’s providing to the grid?

Pitch distance vs clearance distance?

What is the GCR?

Where does the recommended pitch come from?

What is the minimum post depth I can define? What does the minimum ground clearance represent?

Can I set a 0 m distance from the structures to the fence?

Can I have both vertical + horizontal roads in the same area?

How does RatedPower places the roads?

The no-roads option is disabled although my site is smaller than 5ha, why?

I can’t use border adaptation, why?

Power station inside vs outside DC field? Which one’s better for a higher capacity? Why?

How does the software decide where to place the inverters and power stations?

Is the power station’s height considered in the energy yield calculation?

How can I change the distance from structures to RA?

Why is my layout rotated in the “General Layout” file?

How does the software determine the distance between the roads of a layout?

How can I define the width of the fence?

Topography

What’s the resolution of the arrows shown in the topography?

I enabled some topography restrictions, but nothing happened after I simulated the design.

What’s undulation tolerance?

What’s the difference between the “linked row limit” and the rest of the slope limits?
