Improvements and fixes

The analysis tables now show, for each component, how much energy was lost and how efficiently it ran.

• "Energy Loss" and "Efficiency" now appear for each inverter, combiner box and string, with efficiency averaged over at least 30 days.
• The "Digital Twin" column is now called "Energy reference" and shows measured energy as a share of simulated energy, which can exceed 100%.
• Inverters marked as hidden no longer appear in the analysis page's inverter table.
