TL;DR: In the mid-1980s, researchers at Stanford University surprised the solar research community with the highest solar cell efficiencies that had yet been seen in the laboratory as mentioned in this paper. But tough challenges stood in the way of making the cells both durable and affordable, and two startup companies are pursuing commercial solar generating systems based on the technology developed through EPRI and utility support.
Abstract: In the mid-1980s, researchers at Stanford University surprised the solar research community with the highest solar cell efficiencies that had yet been seen in the laboratory. But tough challenges stood in the way of making the cells both durable and affordable. Many of the hurdles have now been overcome, and two startup companies are pursuing commercial solar generating systems based on the technology developed through EPRI and utility support. Still, experts say interim markets may be needed on the path to utility-scale power generation to ensure the technology's eventual commercial competitiveness.

TL;DR: In this paper, the effects of uncertain variation characteristics of the PV system output on the operations of the conventional power generation system and the storage units are evaluated by simulations, with cost a major consideration.
Abstract: Renewable energy utilization and electricity storage will soon be introduced into the conventional electric power system. This study assumes that a photovoltaic (PV) power generation system, a set of the PV units, is installed into the electric power system with electricity storage; moreover, the effects of uncertain variation characteristics of the PV system output on the operations of the conventional power generation system and the storage units are evaluated by simulations, with cost a major consideration. According to the simulation results, it is clearly demonstrated that the costs of the PV system are influence sharply by the prediction accuracy of their output.

TL;DR: In this article, an integrated non-fossil-fuel electrical power system (NFFPS) developed on a farm at Loughborough, England, was investigated, both for electrical energy consumption on the farm and for export to the national electricity grid for supply to other consumers.
Abstract: The authors describe an integrated nonfossil-fuel electrical power system (NFFPS) developed on a farm at Loughborough, England. They investigates the performance and economic viability of the system, both for electrical energy consumption on the farm and for export to the national electricity grid for supply to other consumers. The performance of the system was monitored over a one-year period, to take account of climatic variations during the different seasons. Results obtained are discussed, together with the economics of the system and the development of control strategies to optimize the profit/energy ratio. The NFFPS described uses well-proven items of plant. No significant teething problems were encountered, and, of the 60 MWh of energy produced annually, almost 80% is exported to the national grid.

TL;DR: In this article, the economic feasibility of using transmission lines to transport solar photovoltaic power from sunny to cloudy regions is analyzed. But the authors focus on the long distance, high-voltage electric power transmission to transfer electricity produced by solar PV systems has received little if any, attention within the U.S. utility solar power community.
Abstract: Long distance, high-voltage electric power transmission to transfer electricity produced by solar photovoltaic (PV) systems has received little, if any, attention within the U.S. utility solar power community. In fact, current thinking among utility solar power researchers and planners has shifted from visions of centralized power stations to one of distributed, smaller generation systems. This shift of interest from centralized to distributed photovoltaic power generation, however, appears to be based in part on an unstated premise of limited land area for PV power plants within a utility's service area. Hydroelectric power planners have clearly taken a different approach. Given the limited number of good sites for large scale hydropower generation and the adverse land-use relationship between densely populated, electric power demand centers and the construction of hydroelectric facilities, long high-voltage transmission lines are typically required. In this paper an order of magnitude analysis is made of the economic feasibility of using transmission lines to transport solar photovoltaic power from sunny to cloudy regions.
