Benn, I've had requests like this in the past and have found in EVERY case the customer has no idea that it will take a $$$multi-tens-of-thousands to replace the generator power. If you have the estimating experience, throw out a very large ballpark number to see if their eyes get wide. You may find that they say, "Really? ...That much?"....And then you're done.

The problem i'm having is determining the energy consumption of music/stage (amps, speakers, lights, etc...?) loads as well as concession. The organizers have never considered the kwh of electricity used and it has never been metered. I believe the attendance of one festival is expected to be in the range of 5000 and the other closer to 15000 over the course of a weekend. Do any of you have any experiences in this area? How were the loads determined? No doubt that generator back-up will still be needed, to what extent, will be determined. So what we're looking at would be a temporary off-grid PV system with generator back-up... Any suggestions on how to proceed with this one? benn DayStar Renewable Energy Inc. b...@daystarsolar.ca 780-906-7807 HAVE A SUNNY DAY
