The Money Part
Your power bill breaks down into two main costs: what you pay for electricity and how much you use. NV Energy charges more during peak hours (1pm to 7pm in summer) when everyone's AC is running full blast. This is exactly when solar panels are most productive.
The sun hits your panels hardest during expensive rate periods. Your meter runs backward, banking credits for nighttime. Over the month this levels out your costs, especially during brutal summer bills.
Most Vegas homes use around 1,100 kWh per month. At peak rates that's nearly $300 just for electricity. Solar lets you dodge these high rates when they hurt most.
