Here’s an idea:
When looking at an individual system, or in a comparison, the data tables currently have headings, and each row has a data point with its unit appended. For example 360.56kWh, or 360W, or 49%.
If you instead but the unit in the header, such as Energy (kWh), Average (W), Energy Perform (%)… and then left the rows with normal numbers, that would make it easy to copy and paste the table into Excel or similar for further analysis.
Hope that helps, cheers!
