Client : McHugh Engineering
System Size : 99.6kW
Approximate Yearly Output : 135,100kWh
McHugh Engineering and Solar Bay partner to drive down electricity expenditure with a Commercial Solar Solution.
99kW PV Commercal Solar System installed to reduce reliance on the grid.
Average yearly electricity spend was $20,800
Expected new yearly spend close to zero, after revenue from electricity exported.
Future proofing the business and ready for battery install when commercially feasible.
Energy reliability and reducing cost was Les Mchugh’s two goals for looking into solar. With the cost of energy increasing, it makes operating a manufacturing company more difficult within Australian borders. Les trusted Solar Bay to provide the best energy solution. A 303 panel, eight tonne commercial solar system was installed, and a backup diesel generator was explored.
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.
As only an accumulation meter was installed Solar Bay installed a temporary energy meter that recorded energy usage every 30 seconds. Data analysis showed that the business had a energy consumption profile well suited for solar. As the client goal was to increase energy independence the system was sized up the maximum eligible for the upfront subsidy, 99kW. As the system will export significant amount of energy an energy plan was selected that maximised revenue, at a future date a battery system will be connected to store this energy, resulting in a highly energy independent business.
With a sub-station located directly behind the Main Switch Board the grid application process was straight forward.
A structural assessment was completed and the results allowed for flexible panel placement, the north facing roof was selected to maximise generation.
Three Fronius 27kW inverters were each wired with 33kW of solar modules, the Switchboard location allowed for a straightforward wiring run and install.
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 two weeks to install the system.
A detailed handover and instruction manual was provided to McHugh Engineering to ensure all of their questions could be answered.
