Series: Marine Engineering and Technologies %D 2010 %I Astrakhan State Technical University %X There is engineering design of effective solar power photoconcentrators in order to receive electric power at the ship¡¯s systems. The constructions have flat mirror reflecting surfaces, capable of single and double reflection of solar en-ergy, and an adapting surface of different configurations: flat, round and triangular. The mathematical equations for calculation of constructive characteristics of photoconcentrators and equations for increase of efficiency of incident radia-tion power on the photoelectric cell are given. The calculated optogram analysis of optical concentration factors indicated that the most effective construction for photoconcentrators is a triangular one. %K photoconcentrators %K equations of geometrical characteristic %K equations of optical efficiency %K optograms %K recommendations. %U http://astu.org/content/userimages/file/sea_2_2010/20.pdf
