Electric Vehicle Charging Station at Hoover Dam

The Bureau of Reclamation, Hoover Dam Office, located approximately 30 miles south of Las Vegas, is performing market research to construct an electric vehicle charging station and is requesting industry participation.
1. Would using solar panels as a source of energy for charging on the parking garage roof add to the cost of the project, or make it more self-sustaining?
2. If solar panels WOULD increase the cost, would it be preferable to simply focus on using the available electricity generated by our power station?
3. What would be a reasonable time frame for constructing several stations.
4. Our needs are:
a. 1 charging station at the warehouse.
b. 1 charging station/receptacle at the tailbay
c. Charging stations available for commercial use on top floor of garage and AZ parking lot.
d. Charging stations available for commercial use by employees.
5. Do you have variable business models? For instance, is there a model where the cost of infrastructure is borne by the contractor but they are able to recoup through revenue of charging?
6. Are maintenance and service performed as part of your package?
7. How much labor would be required from government employees to maintain the equipment?
8. Who ensures the stations are working properly?
9. How long do these stations last?
