Large Scale Ground Mount Systems

What racking company would you use for large scale ground mount systems, 100kW+
The cost of labor is a significant factor also.

Thanks
Philip

    Not that I can help you with a recommendation, but is this going to be in the Milwaukee, WI area?

    No the Milwaukee job is not ours. Looking at different systems today, it appears some are driving an I-Beam into the ground. This seems like it can reduce labor cost quite a bit.

    Got another question, are solar trackers still feasible? With Module prices hitting sub $1/W, its hard to believe one would want to deal with the hassle of moving parts. They say it can deliver up to 25% more energy. My guess is that the initial investment would have to be under 10%, as service and maintenance is increased also.

    Its easy to compare the tracker system cost to PV panels, probably will fall in favour of more PV and no hassles...

    Here is an older thread (2009) about:

    Solar Trackers for PV -- Worth it ?


    "Dave Sparks", and installer that specializes in Off-Grid systems in the California Sierra Nevada Mountains still likes trackers because of better battery life (more hours of charging during the day)...

    You may also be able to make a case if you have grid power and Time of Use metering (can be as high as $0.50 during summer afternoons in my area of California) vs the $0.09 for bottom tier off peak net metered power.
