Radcoflex Australia Commercial Solar

Client : Radcoflex Australia

Tags : commercial solar

System Size : 60kWp

Approximate Yearly Output : 85,400kWh

Radcoflex Australia and Solar Bay partner to drive down electricity costs with a commercial solar system.

Radcoflex Australia Commercial Solar Overview


Average yearly electricity spend was $52,480


Expected new yearly spend is $33,069


The solar system will reduce total grid consumption by 32%, reducing volatility in expenditure moving forward.


Radcoflex's total energy consumption was over 160MW which resulted in them being on high network access, and capacity charges.


The commercial solar system was sized to reduce their total energy consumption below 160MWh/p.a. Moving them to a new network tariff and significantly reducing their total electricity spend.


60kW PV Commercial Solar System installed to reduce consumption from the grid.

The Result

Reducing cost and looking after the environment for future generations was Mat Carrol’s two reasons for looking into solar. Within a year, Mat knew he made the right decision going with Solar Bay. In April 2017, Mat’s Monthly electricity bill was $4,600.12.

After Solar Bay; analysed Radcoflex’ account, installed the 60kW system and had decreased his grid consumption enough to request Radcoflex be moved to a small market network tariff, their April 2018 energy bill was reduced to $1,551.32.

The Process

Site Visit

During the initial site visit Solar Bay collects information on the existing electricity contracts, roof weight bearing and generation capacity, buildings electricity consumption profile, and most importantly the client goals.


Energy interval data and network tariff analysis showed a 60kW system would reduce total grid energy consumption to a new threshold allowing for a network tariff change, while only resulting in minimal export.

Grid Connection Application

Grid connection was a straight forward process, grid protection was required, as expected.

Structural Engineering Certificate

Due to internal cranes at the site the load bearing capacity of the roof was not a limiting factor of the install.

System Design

Two Fronius 27kW inverters each with five strings were designed to maximise performance, at minimal cost.


Safety was taken into consideration from the first site visit. All measures were put in place for OHS, working at heights and electrical safety.


After identifying the location for the inverters and cabling, the team worked for 10 days to install the system.


A detailed handover and instruction manual was provided to Radcoflex to ensure all of their questions could be answered.
