Motivation[edit]

Solar irradiance is the rate measured at any given point on earth (usually power stations) for the power per unit area received from the Sun in the form of electromagnetic radiation. Rehman 11:33, 10 March 2019 (UTC)

  • Pictogram voting comment.svg Comment One point: I think the label should contain "annual" to make this clear. --GPSLeo (talk) 18:32, 11 March 2019 (UTC)
GPSLeo, true. But would that mean we need separate properties for "per day" and "per month" or any other period? Rehman 11:22, 14 March 2019 (UTC)
I think per day dose not make sense for power stations because it is always just a mean of many days of many years. --GPSLeo (talk) 11:51, 14 March 2019 (UTC)
You're right. I'm ok with your label suggestion (i.e. annual solar irradiance). Rehman 14:37, 14 March 2019 (UTC)

  • Symbol support vote.svg Support Pictogram voting comment.svg Comment: I think we have to be precise with the wording here: For (solar) power stations the Global Horizontal Irradiance (GHI) is the value to be applied. Therefore, I propose the label Annual Global Horizontal Irradiance. --Katjos (talk) 20:34, 14 March 2019 (UTC)
@Katjos: This does sound like what we want, and is well defined. We should have a Wikidata item for it then? And I don't think "annual" makes sense as part of the label, it's defined as a power level so energy per unit time, the time unit on which it's measured is not part of the meaning (but could be attached via a qualifier if that seemed important). So I would advocate labeling this "global horizontal irradiance" with GHI as an alias. ArthurPSmith (talk) 19:13, 15 March 2019 (UTC)
@ArthurPSmith: I do agree with you. I followed the suggestion from GPSLeo above to specify the time frame. However, I agree that we should add the time as a qualifier. I added items for total solar irradiance (Q62071458), direct normal irradiance (Q62071452), global horizontal irradiance (Q62071435) and diffuse horizontal irradiance (Q62071441) as subclasses of solar irradiance (Q7556707). --Katjos (talk) 20:24, 15 March 2019 (UTC)
I'm fine with this. But does that mean we would need four separate properties, instead of one? See also: Solar irradiance#Units. Rehman 01:19, 16 March 2019 (UTC)
