Results
Results obtained using the high resolution solar model can be found in this section.
Hourly Data
Firstly the solar model has the capability to generate a CSV file of data hence a leave-one-out cross validation was performed on a list of data as shown in Table 1. The validation process was performed on 06/06/2006 where Met Station 692 is situated [51.8603, -1.6915]. An hourly global solar radiation map can also be created with the use of the HRS model. The slideshow below shows hourly maps on 06/06/2006. |
The hourly map allows for cloud cover to be mapped as the contours on the map show areas of low solar radiation and by comparing consecutive hourly maps areas of low solar radiation can be tracked.

Daily Data
Running the HRS model for a day both hourly values and daily values can be obtained. The mapping tool also has the ability to generate maps of a longer period of time. Hence two daily maps from different dates are shown below in Figure 1 & 2 from 01/01/2001 and 06/06/2006 respectively, these maps easily indicate the difference in solar resource in winter compared to summer. From the Met Office Data the daily average on 06/06/2006 is 306.4 W/m^2 compared to the value generated from the HRS model 272.0 W/m^2 this shows an absolute error and percentage error of 34.4 W/m^2 and 11.2% respectively.

Tasks in Progress
- Attempt to reduce the operating time
- Add additional features to the program such as:
- include comment lines to the code to increase readability
- having the ability to create multiple maps to show the hourly variability of solar resource
Results to be obtained
In addition to obtaining the results above, the HRS model will be used to:
- Obtain more hourly data series - to perform an extensive leave-one-out cross validation
- Obtain daily averaged monthly solar radiation maps to compare different months of the year
- Obtain daily averaged seasonly solar radiation maps to compare different seasons
- Obtain daily averaged yearly solar radiation maps to compare different years
