Issue:
Discuss type for renewable category for Ukraine UA
Currently, there is no breakdown for the Ukrainian renewable category provided on https://ua.energy/diyalnist/dyspetcherska-informatsiya/dobovyj-grafik-vyrobnytstva-spozhyvannya-e-e/

The renewable category (ВДЕ) is mapped as "wind" in the parser, because wind used to be the dominant source in the past.
Going through the last few days on the website, you will notice a very clear solar peak at noon (~1.200. MW) each day. Wind at nighttimes reaches a maximum value of ~400 MW, mostly it is around 200 MW.

Here is an example for yesterday:

The installed capacity of solar grew very fast, and will continue because it's cheap and the potential in UA is huge:

Some suggestions to deal with this situation:
1. Any artificial boundaries (depending on x-axis-time or y-axis-megawatts or both) pushing production to wind or solar?
Like "from 06:00 to 18:00" -> solar if P > 200 MW, else wind". 
2. Put renewables to unknown category with a mixed carbon intensity (looking at the intalled capacity, 50% wind : 50% solar seems reasonable).
3. actively search for a breakdown of wind and solar
4. ask the data provider for a breakdown


Discussion:
A conservative answer would be to do 2. I'd say.

If we put it in "unknown", can there be a way to tell that this unknown is "renewable", in the computation of the renewable percent of the country? I don't think so, but it could be a good thing to implement, what dyou think?
Orkney is currently all unknown and yet showing 100% and 100% renewable, so looks like you're already able to do that somehow?
Let's do number 2, a 50/50 split of wind/solar for carbon intensity looks good to me.

Need to find someone who speaks Ukrainian to get in touch with them as well.
