A friend has a 150 kva pad mount transformer at his commercial facility. They are considering installing a 188 kW AC, 150 kW DC solar array. Their average hourly demand is 19-22 kW across the last month and last 12 months respectively. It's a retail store without a lot of loads that peak higher than that, with the possible exception of their AC.
Would they need to replace their transformer with a larger kva unit? If they decided to go with a smaller array, at what DC power output could they stick with their current transformer?
