How to save project sites

For saving project sites in Prospect you just need to follow these simple steps:

  1. Select a location on the map or type location (or coordinates) in the search box. If you are not able to click on the map, make sure the "site" icon on the right is selected.
  2. Click on "save as project".
  3. If you want to customize the name of the project, open the project and click on the "edit" icon on the top.

How to adjust project settings

In order to obtain PV electricity yield estimate and overview of system losses, it is required to add a PV configuration to your project. The first step is to select a system type.

Once the preferred system type is selected, you have several options:

  • Keep the default settings for the selected project type
  • Copy settings from a previously stored project
  • Go through the customizable fields. Use "Expand all" for having the full overview of the editable fields:
  1. System size. Insert the value either as Installed capacity or Area of installed PV modules.
  2. PV module type. Select the PV technology (c-Si as default, more to be added soon) with the possibility of adding custom degradation rate.
  3. Geometry of PV modules. Adjust Azimuth and Tilt (tracker configuration to be added soon) with the possibility of getting the optimum configuration (reference used South=180º, North=0º, East=90º, West=270º).
  4. Inverter type. Select inverter type among the available choices (Small, String Inverter, Centralized)
  5. Transformer type. Select the transformer type among the available choices (Standard, High efficiency, None).
  6. Snow and soiling losses at PV module. Insert snow losses at the monthly level and soiling losses at the annual level expressed in %.
  7. Cabling losses. Adjust the expected values for the main subcategories of losses expressed in %.
  8. System availability. Adjust the expected value expressed in %.

As a final step, for applying changes click on the button Save and calculate PV electricity.

How to set the PV system size

There are  two ways of putting the info of the system size in Prospect:

  • The area of installed modules
  • The total installed capacity

Both values are related in Prospect with a reference ratio of 6468 m² of modules area for 1MWp installed capacity. This is equivalent to a PV module efficiency of 15,46% on standard conditions. 

Please note the area of installed modules does not represent the total ground area covered by the PV field, which will be larger due to spacing between rows.

How to define PV field row spacing

One of the inputs for PV project setting in Prospect is the relative row spacing, which is defined by the ratio of distance between the neighboring PV table legs and PV table width (see below picture). 

It was established that row spacing must be planned in order to limit shading of a module row on another. The row spacing can have an impact not only on the irradiation falling on the panels, but also create shading effects that can result in yield losses.

Example: x2=2000 [mm] x3=5000 [mm], Relative Row Spacing = 5000/2000 = 2.5

What system types are supported in Prospect?

Prospect app offers the following system types:

  1. Ground-based fixed mounted
  2. Tracker with 1 horizontal axis
  3. Floating PV
  4. Rooftop small
  5. Rooftop large flat roof
  6. Rooftop large tilted roof
  7. Building integrated

Can the DC/AC ratio be changed?

By default, a DC/AC ratio of approx 1.2 is used in simulations done in Prospect. There are small nuances depending on the configuration that are chosen, but this varies very little. The DC/AC ratio depends on the module type, inverter type, installation size, etc. 

The current target was to set it close to 1.2 to avoid inverter clipping. We are planning to implement a feature to allow users to adjust this ratio. 

Can I modify the soiling loss parameter?

Soiling loss of 3% is used as default value in the PV system configuration. Currently, it is only a suggestion and you can edit it. Instead of using a single annual input you can also consider specific values for each month.

We are planning to add this parameter later into our maps and database, thus it will be tailored to site specific conditions.
