Fred and Noela’s farm near Mundarlo has an average daily electricity use of 45 kWh. Their main appliances include:
– Reverse cycle heating and cooling.
– Pumps for garden and domestic water supply.
– Pool filtration.
– Fridges and freezers.
The home is quite a distance from the meter box and transformer pole, and this presented a problem. Electrical calculations revealed that if solar was installed on the house roof, there would be voltage rise issues to contend with and major system design limitations.
A workshop shed much closer to the meter box would be a great location for the solar panels, however, it didn’t have electricity connected, so a new underground electricity supply and a switchboard was installed for the shed.
To make maximum use of the available roof area, a panel array consisting of 24 x 360W LG solar modules (8.64 kW) was installed in landscape orientation. An 8.2 kW Fronius inverter was used, and because the electricity supply is single phase, a grid export limit of 5 kW had to be applied.
As there is no internet connectivity at the shed, Solar Analytics 4G was used for energy production & consumption monitoring. This will provide the ability to monitor & manage electricity use during the day, and help maximise the benefit from solar generation. With Solar Analytics, Fred and Noela have peace of mind knowing that we can also check on their system remotely at any time.
Overall, it is forecast they will generate a saving of around $3600 per year in energy costs, and taking inflation into account, a saving of over $110k on electricity bills over the life of the system.
