One row per site, for the same period. Columns: site name, size in kWp, actual kWh, expected kWh. Separate columns with a semicolon or a tab, never a comma. Numbers may use a point or a comma for decimals, and a comma, point or space for thousands.
Illustrative only. Expected energy must come from your own model and weather data. The preset is a synthetic 40-site fleet (days 150 to 179 of an invented year), not real plants. The 130% check level is set by this page, not by a standard. Two other lists use a fleet median, so they flag climate and size, not faults.
