QUESTION
I recently ran into an issue with calculating the clearness index and the extraterrestrial irradiance using the PVLIB functions. Basically, the numbers do not tally up.
This is my raw data that I ran the function for (my Datetime is already timezone aware):
I then ran the below code to get the clearness index:

I have a timeseries with data related to the irradiance of the sun. I have data for every hour during a year, but every month has data from a diferent year. For example, the data taken in March can be from 2012 and the data taken in January can be from 2014.

QUESTION
I simply need an example of the yearly in plane irradiation using irradiance
, given the latitude, the longitude, the tilt of the surface and the azimut, in order to automatize my process later.
I need to do this computation in order to compute Actual vs. Theoretic Production Ratio of some plants in central EU timezone.
My aim is to obtain the same number provided by the graphic user interface: Summary Section of the PVG Performance Tool, so I suppose that they provide the "typical" annual irradiation, caring about the effects of cloudy days.
Thank you very much! Any kind of help would be really appreciated.
...ANSWER
Answered 2021-Mar-09 at 08:32pvlib has a function for retrieving PVGIS TMY time-series, which include GHI, DNI, DHI, temperature, wind speed, and a few others for Europe and Africa.
I am currently working on a pull request for adding capabilities for retrieving PVGIS's hourly radiation and PV power output to pvlib (exactly the parameters shown in your image). You can find the code by going to the file part of the pull-request and copy it to a file on your desktop and it should work smoothly. Let me know if you need any help using it.

QUESTION
I have a dataframe with hourly measurements of 6 different meteorological variables for a year. I have tried to create subplots that show both the houryly and the daily average for each meteorological data in the same subplot. However, I'm not getting any close.
With this I get the subplots for each variable:
...ANSWER
Answered 2020-Dec-03 at 17:31I think you're close. The main issue I can see is that you're not directly utilizing the Axes object you created before the loop.
I would loop through those and your dataframe columns directly and always pass the Axes object to the dataframes's plot
method.
QUESTION
I am using pvlib to calculate diffuse and direct incoming solar radiation at the surface and this works well. I account for clouds, albedo, sea-ice etc. when calculating the total incoming shortwave radiation at the surface.
...ANSWER
Answered 2020-Dec-02 at 16:26I don't recognize a conceptual error. What do you get when you integrate the spectral direct irradiance? I'd expect to recover the sw_dr broadband value. Something to check. The line of code that calculates uvi looks odd. sw_dr from total_irrad is a Series, sw_dr(λ[280:400]) indicates that sw_dr is a function.

I have written a code to perform some data cleaning to get the final columns and values from a tab spaced file.

Answered 2020-Nov-16 at 22:14There are various ways to do it. You can append
one dataframe to another (basically stack one on top of the other), and you can do it in the loop. Here is an example. I use fake dfs but you will use your own
