This taken from the Solar Power site,
It appears that Theo's system would falal in under the maximum they say
as 12 panels taking it up to 2.4 kw is definitely under the Synergy limit of
5Kw and way under Horizon limit
as Horizon state, anything over 5 Kw must be discussed with hem first
So I would say that Theo would be safe installing the extra panels
************************************************
Residential Net Feed-in Tariff Scheme participants will receive the premium
rate for 10 years. Solar power systems will be limited in size to 5kW for
Synergy customers and 10kW per phase (30kW in total) for Horizon Power
customers.
On August 1, 2011, Western Australia's feed in tariff installation quota
was reached and the program suspended for new connections. However, Synergy
and Horizon Power will continue buying excess electricity fed into the grid
from all residential solar power systems under the State Government's
Renewable Energy Buyback Scheme at 8c per kilowatt hour.
In April 2012, Horizon Power announced from from 1 July 2012, it would pay a
minimum buyback rate of 10 cents per kilowatt hour and a maximum of 50 cents
per kilowatt hour will apply to Horizon solar customers, depending on
location.
*** Note: System size must be consistent with Renewable Energy Buyback
Scheme (REBS) which is 5kW for Synergy customers and 10kW per phase (30kW in
total) for Horizon Power customers (Horizon Power customers installing
greater than 5kW must consult Horizon Power first). These are determined by
the size of the inverter.
