As states implement renewable energy mandates, and as solar photovoltaic (PV) technology becomes more economical, the market for distributed rooftop solar is growing. As a result, various players are taking different approaches to finance PV development—from net-metered residential systems financed by third-party leases, to grid-scale, utility-owned projects. Fortnightly Contributor William Atkinson talks to some major players in solar PV finance and examines the implications for investor-owned utilities.

(October 2011) Wind Capital group selects RMT Inc. to design and construct wind energy facility; MEMC Electronic Materials, Inc. and SunEdison acquire Fotowatio Renewable Ventures; Solar Community and Reliant Energy team up to offer financing options; KEMA selects Green Energy Corp.’s software; Leviton unveils commercial electric vehicle charging stations; plus announcements and contracts involving Science Applications International Corp., Tantalus, FirstEnergy Nuclear Operating Co. and others.

(March 2011) TVA and EPRI demonstrate solar-assisted EV charging station; Ford unveils the all-electric Focus; Central Maine Power awards substation contracts; ERCOT deploys ABB software in nodal market; FirstSolar starts up PV plant for Southern Company and Ted Turner; plus contracts and announcements involving Open Systems International, Verizon, Suntech Power, Alcatel-Lucent, Siemens, Cisco, Elster, Sensus, Silver Spring Networks and others.

The future looks bright for distributed photovoltaics. New technologies and government policies are driving a revolution in PV manufacturing. But a robust national distributed generation system requires a grid that can accept two-way control of electrons.
