We installed a 6.48kw system on this house in Ipswich. The owner worked from home and had 2 computer servers on 24 hours a day, and his office from 9am to 5pm. We opted to instal 10 panels on the North and 14 panels on the West. The additional panels on the west was mostly for his summer use when he runs a small airconditioner.
The hot water service was placed onto a timer and timed to switch on at 12 noon and off at 2pm. The reminder of teh day the panels powered his house, giving him extra power in the afternoon for his small airconditioning unit
