How Much Solar Should I Install?
I have a building in San Antonio, TX that I want to put solar on the roof top. What I can't figure out is how much solar makes economic sense.
The building is a warehouse/distribution center, with plenty of additional office/administrative people. Primary working hours are 5 AM to 7 PM, M-F. The roof top is flat and is of a nature where the panels can be located optimally. The building is large (400KSF) and single story, with nothing other than chiller units and warehouse exhaust vents on the roof.
Annual electricity consumption is 1,784,736 kWh, at a cost of $149,141 ($08.5/kWh).
How do I determine how much solar PV to put on the roof?
And should I instead contact someone who will lease a system to me at a fixed $/kWh charge?
