[Convert weather data file to .DAT or other for PVSOL]

Hello, I have a .MET file from a solar station, how can I convert to a PVSOL compatible format?

[Doubt about grid feed-in]

Hi UserPV,

could you provide an example project file so that we can take a look at it?

Thanks a lot, kind regards,

Martin

You can use as an example an example of PVSOL, such as plant P90 in germany. The Grid feed-in is 20,062,175 kWh/year, while in "PV energy during observation period" is 18,926,713 kWh / year for the first year.  I did not understand why the difference for more energy injected into the power grid.

[Doubt about grid feed-in]

Hello, because in simulations the value of the "grid feed-in" is lower than what I indicate in "PV energy during observation period", since they are annual value.

Ex:
grid feed-in: 1670kwh.
PV energy during observation period in first year: 1645kwh.

Also, where can I find the theoretical (lossless) annual energy value (kwh)?

Thanks!

[Systems with Trackers in 3D mode]

Thanks! What would be the best way to save shade losses?

[Systems with Trackers in 3D mode]

  Is it possible to do simulations in 3D mode with 1-axis N-S trackers in PV * SOL?

If it is not possible, could you import a ".hor" file from 3D mode to make a common simulation, considering the shading?

[Behavior of PR in simulations]

Hello, I did some simulations on the PV*SOL for a scenario with enough objects to cause shadowing. However, for a 30 kWp system, the PR was better for the city with more clouds and lower temperature, while the Annual Yield was higher for city with higher temperature.

Values:
City higher temperature (1846kWh/m2) - PR 68% - YR 1,170.00 kWh / kWp
City lower temperature (1467kWh/m2) - PR 72% - YR 1,074.00 kWh / kWp

What may explain the behavior of PR, I think it should be higher for city with higher temperature. As happened to a lower power system.

 

[Small increase of PR in simulations with power optimizers]

Hi, I've done some simulations involving power optimizers, from Tigo and also Solar Edge. The results in the increase of the performance ratio were small, even in situations of shadowing.

Example of a result (performance ratio): 73.6% (without optimizer), 75.8 (with optimizer Tigo).

Soon,

1 - The use of optimizers is being viable in the market?
2 - When simulating, which parameters should I configure for best results?

And I have tested and followed as an example an example of PV*SOL itself.

Thanks!

[Shortcuts in 3d mode]

Hello,
I would like to know if it has a shortcut to rotate a set of objects. Example, if I have a house to the north and want to rotate to the south, all set of objects.

[Doubt about the Neuhardeberg power plant example]

Hello, I was simulating the example of the Neuhardeberg power plant. However, I saw that it has 145 MW (https://blogthinkbig.com/solar-photovoltaic-power), so the simulation is only part of the plant? For PV*SOL has 82042 modules.

I found it strange that this site (https://blogthinkbig.com/solar-photovoltaic-power) says: "With an output capacity of 145 MW, this plant can produce approximately 19,690,000 kWh of renewable electricity per year." I think the information seems to be incorrect.

[Obtaining annual forecast of generation over lifetime of photovoltaic system]

Hello, I would like to get the annual average generation of at least 10 years of a photovoltaic system. Observing the losses during its useful life. How do I do that?

In PV*SOL i only observe the generation in a base year (Option Production forecast).
