Overcame rural challenges for infrastructure projects.

The Challenge

Increasing costs and incorrect network charges were the two biggest challenges for Drury Farm. Also, being near the end of the network, voltage issues and brown outs also posed as a problems.

The Equipment

Two SMA 15kW Inverters


Trina 275 Watt Panels

Production - Daily

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.
