can sell them for on a dollarper-square meter basis to make the resulting PV system no more expensive than when using a fixed mount system. Using simple dc, STC ratings along with the following assumptions, how much can the trackers cost $/m2?

1. Trackers see one-third more insolation.
2. Modules cost $4/W and have conversion efficiencies of 10%.
3. Inverters cost $1 per W of module.
4. Installation cost is the same for fixed mount and trackers.
