Have Huge coporations that own/lease huge warehouses and buildings to install solar power based systems .

Yearly, warehouses and other buildings owned/leased by large corporations, consume a lot of resources in the form of Electricity. These buildings have open roofs and huge surface areas that are available for the installation of solar power units that will atleast generate 1/3rd of the required power during the 5-6 hours of sun light during peak summer. The cost of installing these units could be claimed as a tax refund, like the ones given to home owners. Also selling excess power if any will pay for the units over the period of time.
As a home owner with a solar power unit, I have personally seen my energy bills shrink by $55/mnth with a 2 KWH solar panel . Just imagine a solar power unit installed on the roof of a 10,000 sq ft warehouse could produce.
