We’ve been collecting general weather data for Crondall since February 2006, but in late January 2020 added a solar sensor to allow us to start tracking sunshine hours, solar energy and Evapotranspiration.
Here’s an easy to view monthly overview of the Solar Energy measured in watts / m² (average, minimum and maximum) so you can easily see the variations for the various months (and in time years), as well as scanning the months of any particular year.
As well as the monthly summary, if you’d like to see how each day breaks out within a particular year then select the “daily detail” radio button, and if you’d like to see how the various seasonal averages compare then select the “seasonal summary” radio button where we then summarise as follows:
Northern Hemisphere Meteorological Seasons
Winter: December, January, February
Spring: March, April, May
Summer: June, July, August
Autumn: September, October, November

Very useful data. I want to use some of it to help determine how much electricity our shop will generate with a given PV array, and how much of that will have to be sold to the grid. I should be able to get a good idea by using daily insolation and applying a sine wave to find approx hourly data. (I suppose you don’ t have hourly figures do you?).
I think the “solar kWh ” figures look most appropriate. Could you explain what that actually is. Also can ethe figures be downloaded to csv format?
Thanks

Hi Andy,
Glad you are finding the data interesting and valuable :)
The Solar kwh tab measures the kilowatt hours of solar energy received per square metre which is as you mentioned I think will be the most approriate measure for you.
We actually log the solar every minute, and I’m very happy to send you say the April log file to see if it would suit – just let me know.
Many thanks
Neil
