sentences:  The daily average radiation is 4.5 kWh/m2, and the area with the best solar resource is the Guajira Peninsula, with 6 kWh/m2 of radiation.Of the 6 MW of solar power installed in Colombia (equivalent to about 78,000 average-size solar panels), 57 percent is distributed in rural applications and 43 percent in communication towers and road signaling.Solar systems can be very suitable for applications in rural areas, where energy demands are dispersed and modest and grid connection is often more costly (UPME 2005).
