Development of Solar Energy Bike for Electric Generator by Self Reliance in Anubankohkood school, Trat Province.

Abstract

The research aimed to study the amount of produced electricity per application and to Integrate this research with instruction of Anubankohkood School. Two of three-wheel-bicycle equipped with four series DC motor of 350 watts,  in total 1,400 watts, together with two panels of 300-watt solar cell charging the electric current into the 24-volte; 150-ampere battery. The integration with science subject learning of grade 1 to grade 6 by cooperating with 113 undergraduate students of Technology Program from Faculty Industrial technology, teachers and other interested people. The satisfaction questionnaire with five 5 levels of rating scale was used. The results found that cycling at a constant speed 15-20 kilometers per hour could produce electricity at the average of 3 percent of battery capacity, the solar panel could produce electricity current 5 pervent, and when combining cycling with the solar panel, the electricity current was increased 7 percent. Efficiency of electricity storage when combined both systems together was better than used cycling or solar panel alone at 66.67 percent and could store the electricity current in the battery within 10 hours. The items of satisfaction towards knowledge and understanding gained level 1 including knowledge on theory of electricity energy and knowledge after training and practicing mean (X) 4.65 or 93 percent. The satisfaction towards knowledge transferring of the lecturer gained the highest level with mean (X) of 4.78 or 95.60 percent. In terms of knowledge application, the ability to apply learned knowledge to increase the potential of self-production of the electricity obtained the highest level with mean (X) of 4.77 or 95.40 percent and they wanted to know more about new renewable energies.
