Coastal Cold Storage are an Australian family-owned business that have been in operation for over two decades. Located in North Geelong, they specialise in the receiving, storage and dispatch of frozen products. As a 24-hour cold storage facility, Coastal Cold Storage were looking for a way to offset their high electricity costs and turned to Solgen Energy Group for a solution.

Sunshine benefits day and night

As a result, Solgen Energy Group proposed the installation of a 65kW rooftop solar system. A 30kW system was initially proposed to cover their daytime usage as the bulk of their usage was not during sunlight hours. However, with their high electricity bills and the high feed-in tariff available in Victoria, Solgen suggested that they increase the system size to 65kW to not only offset their daytime energy use, but also offset the cost of their night-time use with the feed-in tariff with the view that a battery solution could be installed for the facility in the future when they are more economically viable.

As part of the design, Tier 1 Trina Monocrystalline 300W panels were used for their efficiency and high output. Similarly, Delta inverters were also suggested due to their versatility within the design. Non-penetrating mounting was required due to the roof material, however being a fairly tall building, wind loading on the structure was also a concern. In order to minimise this, panels were installed at a 10-degree low pitch with tilt legs and non-penetrating clamps. Additionally, due to the height of the building a crane was required to lift the panels to the 10m high roof. All together, the project required a large amount of coordination by our project management team due to the fact that the facilities were in operation at the time of install.

Solar system peak capacity: 65.4kW
Panels: Trina Mono 300W
Inverters: Delta

Maximum results with EUA

The system was financed in conjunction with Sustainability Victoria and the City of Greater Geelong as part of an Environmental Upgrade Agreement (EUA) which allows the solar system repayments to be extended to 10-years at low interest via council rates. This finance is approved locally via the council, minimises credit application requirements and the amount can be increased over time to upgrade the system if necessary. Additionally, by signing up to an EUA with the City of Greater Geelong, Coastal Cold Storage have an initial cashflow positive position of $2,100 per year versus paying their ongoing power bills. By implementing the system via EUA financing Coastal Cold Storage have an oversized solar system that is cash-flow positive from day one while only consuming 43% of the system’s total solar generation.

Overall the installation was a success, with Coastal Cold Storage estimated to offset $12,000 annually off their electricity costs with a system that will also offset approximately 100 tonnes of greenhouse emissions annually using the power of the sun.


The implementation of a 65.4kW rooftop solar photovoltaic system through an EUA at Coastal Cold Storage is expected to:

  • Bring this investment cash-flow positive from day one with a return of $2100 each year;
  • Offset close to 100 tonnes of greenhouse emissions annually;
  • Positively promote the business and the council to the wider community as an EUA user;
