Monterey County -Residence Case Study:
Customers needs: Reduce $500+ energy bill Existing PG&E bill: $500+ per month
System Size: 7.13kW kWh production: 9,660kWh p.a.
Payback: 4.5 years Energy bill with Solar: $40 per month
The customers needs were to reduce their PG&E electric bills, as they were in excess of $500 per month.
The solar electric (pv) system installed consisted of 31 230W solar panels in two arrays of 22 & 9 panels. The two roof mounted arrays faced South West.
These arrays were served by two SMA inverters which converted there solar generated power into AC power for use around the home and to spin their meter backwards.
The system produces 9,660kWh per year and reduces carbon emissions by 167 tons over the systems lifetime. That's equivalent to over planting 6,680 trees.
Their average electric bill is now $40
