Winery and restaurant Hollick Wines in Coonawarra, South Australia was interested in offsetting the high electricity bills associated with evolving their business. Solgen Energy Group was awarded the engineering, procurement and construction of a 100kW solar system, which is estimated to reduce the winery’s consumption of on-grid electricity by more than 50%. The project has gone on to become one of two finalists in the Wine Industry Suppliers Association (WISA) Impact Awards in the engineering category due to its innovative and quality engineering and componentry delivering significant benefits to the estate to be used as a model for the rest of the industry.
Solgen designed and structured a flush mounted array on the winery’s pitched cellar roof using the latest Trina Solar products. The Trina Mono panel was used in the installation for its high power output which means performance is not compromised on cloudy days and other low light conditions. The panel is also self-cleaning which minimizes maintenance for the client.
The Hollick Wines project also included the use of Huawei SUN2000-33KTL inverters (30kVA). This is the first project in Australia to use these inverters which are specifically designed for large-scale commercial power plants. These inverters deliver up to 98.8 per cent efficiency with its featured three Maximum Power Point Tracking (MPPT) while other inverters only have two. The inverter also features power line communication with the Huawei Fusion Smart PV Controller. This feature greatly reduces the amount of data cabling that is needed for monitoring and controlling the PV system.
Customised cable trays were installed by Solgen to enclose the DC cabling running between the panels and inverters. A wireless monitoring board was also installed which allows the client to monitor, control and maintain the solar system easily and safely.

|Solar system peak capacity:||99kW|
The project included a structural engineering assessment and site electrical plan upgrade to ensure system stability. As a result, the client’s existing sub mains were upgraded to 95mm2, which will reduce the voltage rise and cable loss when the system is operating.
The project was installed in 5 days which included the upgrade to service cables. This meant there was a negligible impact on the winery and restaurant, which was fully operational at the time of installation. With the financing options available through Solgen, this project is projected to bring the client cash-flow positive after just the fourth month of operation and will offset 130 tonnes of greenhouse
emissions every year.
The installation of a 99kW photovoltaic system is expected to:
“I would just like to thank you for your efforts in the installation of our PV system. Your service and attention to detail was impeccable and our expectations were exceeded on both value for money and efficiency of our system. I would not hesitate to recommend Solgen to anyone looking to invest in a P.V. system.”
