How Much Sun...

[teslacoils]

Could anyone with solar panels in the east of England give me a rough idea of how much sun they have had this month compared to "normal"? Thanks.

Can you give me till the end of the month, and I will give you as much as you want to know.
I suspect, it will be pretty s**t to be honest.
Could
I ask why you are asking?

Good correlation between June solar output and crop yields. Further north July helps, or so I'm hoping.

Sunshine hours near here:

June 2019 to date 139
June 2018 197
June 2015 204
June 2012 155

But the output is better as factors in the strength.

Graph above is pretty self explanatory
Taken at the end of 26th June..... so 4 full days left in the month

It is, as mentioned by others, to find out about the link to crop yield. I farm a large area as a contract farmer and have often said that all I really do is set it up right for the weather to do it's job.

Was just trying to see roughly what percentage down / up we were for a normal June so far.

I have been looking up data for the various weather stations scattered around South Lincs. The energy input since June 10 (when the monsoon started) is poor. Measured in watts metre square. Taking one station in particular in 2018 most days in June between 200 - 300, lowest was 144. For 2019 highest is 240 and lowest 26 (June 11) yesterday (June 25) was 60 for the day. Potential saving grace (straw to grasp!?) temperatures been cool thus less energy used by plants to survive, though on some of those very dull days possible that wheat plants lost weight as they used more energy to survive than they created. Wheat flag leaves still green so if we do get some sun may not be too late - this year is similar to 2016 grain fill period in my view. Hey ho, time will tell. .

I strongly believe there is a very strong correlation, however outputs can be quite variable over short distances, but over the years they average out.
I will post my figures for June on Monday, or Sunday night if I can't get to sleep

@teslacoils the following is the average production we have had per Kw installed array over the last 6 years during June

Year. Units
2014. 136
2015. 137
2017. 112
2018. 142
2019. 117

we can see no evidence of degradation of the arrays and this is backed up by having the best ever production in the first 3 months of this year, A common factor across the country.
Have you taken into account in your own figures the light reception by the crop in terms of field cover? This was a serious consideration when we were manually assessing transpiration figures for irrigation.
