Why we need Solar Emergency Microgrids

Solar Emergency Microgrid models

  • Scenario 1: Solar+storage
  • Scenario 2: Solar+storage and electric vehicle (EV) charging
  • Scenario 3: Off-grid emergency shelter (21% of load)

1. Hoover Solar Emergency Microgrid scenario 1 (solar+storage)

  • Utility bill cost savings: $34,000/year
  • Payback: 4.2 years
  • Net present value: $242,713
  • Internal Rate of Return: 20.6%

2. Hoover Solar Emergency Microgrid scenario 2 (solar+storage and EV charging)

  • Utility bill cost savings: $35,000/year
  • Payback: 3.3 years
  • Net present value: $261,207
  • Internal Rate of Return: 22.5%

3. Hoover Solar Emergency Microgrid scenario 3 (off-grid emergency shelter)

More than just the right thing to do

  • Economic benefits: All three scenarios will reduce the school’s $71,000/year electricity bill, partly because solar power per kWh is less expensive than power from the grid, and partly because energy storage helps shift loads from times when electricity is expensive to times when it is cheaper. Furthermore, investing in solar+storage hedges against future electricity rate hikes by prepaying part of the electric bill for the next 25 years.
  • Community resilience resource: Natural disasters don’t happen every day, or even every month. But when they do happen, they are devastating to a community. Resilient energy systems can withstand and recover from extreme, damaging conditions.
