Toyota Panel Shop - Wyoming NSW, 2316
Brian Hilton Motor Group - Energy Snapshot
BACKGROUND:
Monitoring was placed into the Brian Hilton Motor Group’s Toyota Panel Shop on the 7th of July 2025 to review the energy usage on the site.
Both the electricity mains and solar generation have been monitored with the following findings.
FINDINGS:
The circled (yellow) energy spike on the energy chart below looks to be attributable to motor start ups. It look as though the spray booth fans and the building compressors are turned on at once. By staging the switching across a wider period will reduce this spiking. There also is a significant amount of solar load that hasn’t got a feed in tariff off the existing bill. Hence the AMBER / Good Earth Group offer.
CONCLUSION:
Variable Speed Drives placed on each of the motors will reduce the constant energy load by 8-10 and the variable switching load by 35-45%. VSD’s will balance any reactive power load and filter power to protect motors and ramp power to avoid energy spikes as shown. A further audit is recommended to build the asset register of these motor loads.
85%
ENERGY REDUCTION FROM THE GRID
Switching 7-9pm every night.
PROJECT UPGRADE — 38kW Solar / 48kW Battery
On the 7th of November 2025, an additional 38kW Solar (30kW already installed) and 48kW of Sigen Battery system was installed. In its first full week of installation this system accounted for 3268.49 kWh of energy supplied whilst the grid supplied 471.71 kWh. This represents an 85.56% reduction of grid supplied energy in total. The existing solar system represented 33.85% of the total energy generated.Note: More work is required to recognise the load switching after hours every day at the same time of approximately 7-9 pm every night. This needs to be done prior to moving to Amber Electric
Toyota Spares & Service - Wyoming NSW, 2316

BACKGROUND:
Monitoring was placed into the Brian Hilton Motor Group’s Toyota Spares & Service building on the 10th of October 2025 to review the energy usage on the site.
Only the electricity mains have been monitored with the following findings.
SUNDAY
MONDAY
NOTES:
Sunday still looks to have a compressor, hoists or air conditioning load still cycling.
Refer to the graph below
SPARES & SERVICE BUILDING
LIGHTING:
The Service & Spares building has lights in the stores and the external part of the building that require an upgrade to LED.
The external lights are as follows:
1 x 700W Metal Halide Flood
4 x 400W Metal Halide Flood
These lights draw 2.53 kWh or 23.5kWh per night (10 hrs) or 8,577.5kWh per year with an approximate cost of $2,358 per year.
LED’s would reduce this cost by 66%. Or a saving of $1556.00 per annum for 13.69 Yrs.
SUNDAY LOAD
SPARES & SERVICE BUILDING
There looks to be a load cycling on Sundays. It may be a compressor, hoists or air conditioning.
The lighting and this cycling when removed will improve the energy efficiency of the building

EXISTING 100KW SOLAR
After reviewing the power bill supplied for the Houma Holdings (Honda) Dealership for the September period, the billing showed 7,150kW of Solar power was being returned to the grid at a payment of $0.02c per kWh or $143.01 or $4.76 per day.
By sizing a battery for the existing solar on this site, I believe this could actually make money for the group by discharging the battery into the grid at peak times through Amber Electric.
The first part of the process would be to put monitoring on the building to build the load profile for the site. The data from this monitoring would be able to be used to correctly size the battery for the load being generated.
The cost for this monitoring installed would be $2,967.14 Inc GST.
