PV system statistics 1999

Tables: Power generated in 1999 by my PV system in kiloWatthours.

The tables below contain the energy delivered by my two solar systems: Solar2900 is a 2900 Watt-peak array connected to a Sunmaster 2500 inverter. (installed March 11, 1999) The Solar100 energy comes from two 53 Watt modules connected to a Sunmaster 150 (installed end June 1999). This column may be used as a reference for a 100 Watt AC panel, a standard component used in the Solaris project from Greenpeace. Simply multiply the value in the column with the number of 100 Watt panels you have and see if your energy compares to mine. The location of this system is Postal code 7546, Enschede in the Netherlands.
