DESCRIPTION:Photovoltaics has become the cheapest source of electricity\, 
 almost globally\, but with growing installations it becomes disruptive for
  the existing system of electricity generation. Often\, electricity from P
 V is discarded because baseload plants cannot change their generation with
  the flexibility that would be needed to accept electricity from PV. Moreo
 ver\, as electricity costs from baseload are mostly from fixed costs\, ado
 ption of PV is decreasing profits. We have developed a system where PV ins
 tead is used to meet all peak load demand above a given level. We demonstr
 ate this system for a European EU27 yearly load curve. Here\, one cable to
  a suitable country on the southern hemisphere allows to get rid of excess
  electricity generation in summer and to meet all peak load demand through
 out the year at costs that are considerably below present peak costs. This
  makes PV highly compatible with the present system and highly desirable f
 rom an economic perspective. Moreover\, this system allows a gradual incre
 ase of the share of solar electricity such that PV always only meets peak 
 load\, although increasing shares of the overall load. We found that Argen
 tine is a suitable country due to its extension over almost 30 degrees of 
 latitude. Through an interhemispheric connection\, electricity generation 
 can take advantages of  all strength of PV\, i.e. ist low costs of electri
 city\, longevity\, low need for maintenance and low environmental  and aes
 thetical impacts. Once this method is proven\, more countries on both hemi
 spheres can be connected which would progressively lower electricity costs
  for all participating countries down to about US cent 3 per kilowatt hour
  for 24/7 meeting of actual demand.
