EMR Switchboards has two electricity meters across the property, requiring two solar systems to maximize return. After a thorough energy analysis, we decided a 20kW and a 12kW solar system would be the most effective solution as one bill was larger than the other. The result? The once larger power bill is now in credit and the other has reduced by 27%. Together the systems have reduced energy costs by 82%, saving on average $850 a month!
Site 1 power bill = $366/month
Site 2 power bill = $676/month
TOTAL = $1,042/month
Site 1 = 12kW solar PV system with a 10kW inverter
Site 2 = 20kW solar PV system with a 17.5kW inverter
Total project cost = $31,500 (after STC rebate)
Estimated payback period = 3 years
Site 1 power bill = $268/month
Site 2 power bill = $80/month CR
ROI = 32%
Current payback period = 3.1 years
