Hybrid Energy Systems Tonga Hybrid Grid Project 500kW of solar PV 100kW of battery storage Ground mounted Fully integrated with existing diesel power station 70% of noon time load of the entire grid is serviced by the PV Rio Tinto Hybrid Grid Project Largest mining and solar off-grid project in the world ~7MW of solar with high penetration Very harsh environment High winds Dirty /dusty Very remote
University of Queensland Lessons Develop a good public (web) interface to show off your system and its capabilities; Spend a little bit of money on simple things like a viewing platform; Spend time analyzing what your optimal (minimal) cleaning regime is to save operational costs; Have a robust and rigorous panel inspection regime in place. It is nice to see German quality engineering and construction in Australia WIRSOL AG ** Top 50 university, QS World Rankings 2011 One of the best examples of quality installation I have seen world wide. Power-One

Is Solar PV Cost Competitive The price of Solar PV has fallen dramatically in the last 5 years For many businesses and building owners, solar PV can provide a cost effective means of lowering their energy bills and locking in savings for the long term The feasibility of PV is highly dependent on the tariff structure It is also highly dependant upon network stability and the details around network connectivity Cost competitiveness can also be impacted by network, safety and local government regulations Whilst PV lowers a business AVERAGE peak demand, it may not consistently reduce it s MAXIMUM peak demand
