I've been given the task of pricing out a 1MW solar project. I don't have much of a background in solar system design but I'm trying to understand how a typical system of this size is constructed and what equpiment is needed in order to come up with an accurate cost for a 1MW project. I have a few questions and I was hoping you guys could help me out.
The panels we will be using for this system have a Voc of 291.4V, Isc of 2.75A and a power output of 530.5 Watts. Maximum system voltage is 1000V.
What factors should I look at when connecting these panels into strings/arrays? I'm thinkng of putting 2 panels in series to give me a string voltage of 582.8V and then putting six strings in series to go to my combiner (with a 20A rating) with a current of 16.5A.
What equipment is needed to conect the output from the inverters? Do they just connect to the inverter?
Do I need a dc dissconnect after each combiner?
Any input you guys have would be helpful,
