Best March ever, well since install in April 2010. Sort of makes up for the dire Jan and Feb. Previous best was March 2014 at 332kWh. This months output was 2.5 times that achieved in Feb.

105kWh/kWp? Looked again and it should be 94.7kWh/kWp (386.4/4.08).  Unless you are dividing the total by the export limit of 3.68kW. |

105kWh/kWp? It is monthly kWh/kWp, not daily. Definitely within expected range. |
