Area capacity iteration tool is used to calculate if it is possible to reach the required kWp capacity in the selected PV areas. It is best to use this tool after having drawn up a few PV areas.

You have to options on how to use this tool:

  1. Run iterations between different frame distances to reach a specified capacity.
  2. Use the tool on large projects to easily run different comparison options.

Reach a certain capacity by iterating pitch distance:

1. First of all, you have to describe preferred frame parameters in the Frame & Park settings. Those parameters will be used for capacity iteration.

2. Next step open the Area capacity iteration tool and input your settings:

Here you can select the PV areas which you want to iterate. Depending on your areas placement, use select Single or Multiple generation areas:

Select single generation area - select the PV areas that should be generated using the single area generation algorithm.

Select multiple generation areas - using this selection will generate PV areas using the multiple area generation algorithm.

ⓘ PVcase will lock which areas were selected as Single or Multiple areas - so you won't need to re-select them again.

In the example above, you can see that I have selected two Multiple areas on the top and one Single area at the botom. The iteration tool will memorize the selection of the areas. Meaning that the single generation areas will be iterated as such with the specified alignment to one side. The two mulitple areas will be aligned towards the middle and will be generated as a group of two areas.

3. When the areas are determined, I have to describe how precise I want to iterate those areas to get as close to the required capacity as possible.

My goal is to find out how high my pitch distance can be so I can generate as close to the required DC capacity as possible.

So, I know I have the required capacity of 30MW and I can go as low as 7864mm. pitch distance.

I enter the start values that are 8890 and a pitch step of 100 mm.

This means that the software will calculate from 8890 to 7864 by decreasing the pitch distance by a 100 mm. every iteration to try and find the optimal distance for 30 MW capacity.

4. Final step is to click Iterate. 

Software will start calculations by going from 8890 to 7864 mm. and try to reach the 30MW capacity.

4. Once it's done, a new window opens and informs you if it was successful or not:

See the results below:

Now I know, that it's possible to fill those areas with a total of 30 000 kWp capacity using a shading limit angle of 21.9° with a 7890 mm. pitch.

After pressing OK, the frames will appear in selected areas with the parameters to reach required capacity.

Use area capacity iteration to easily get different comparison options:

As mentioned before, the Area capacity iteration tool locks PV area generation and alignment choices.

This is great for instance when you have 30 PV areas and you're doing comparison options of different modules or framing. Because you don't have to reselect all of the areas as you would using the simple generations.

This means that at any point you can go to the Frame & park settings to change your framing and just hit iterate again to rerun the iterations with the same areas but with different framing.

If you input a pitch step of 0 PVcase will generate all of the selected areas using only the Start inputs. 

This is extremely useful for when you have a substantial amount of areas and want to leave PVcase to run generation with one type of framing and then come back after it's done to analyze results and change modules/framing/spacing.
