FILE - In this Tuesday, Aug. 3, 2011 file photo, solar panels are seen at the NRG Solar and Eurus Energy America Corp.s 45-megawatt solar farm in Avenal, Calif.  Theres a land rush of sorts going on across the nations most productive farming region, but these buyers dont want to grow crops. Instead developers are looking to plant solar voltaic cells to generate electricity for a state mandated to get 33 percent from renewables by the end of the decade.
