Which has the greatest NPV assuming a 25 year planning horizon and MARR = 12%?
Install a $20,000 solar system that will last 25
years, and generate 38,000 kWh/year at $0.10/kWh.
Install a $25,000 Ground-Source Heat pump that will last 50 years
and save $3,500/year.
Both options has equal NPV
Not possible to be calculated
