Solar power although an abundant source of renewable energy must be utilized properly. One of the main factors to optimize its benefits is the capacity of the consumers to efficiently channel its power. The motivational factor of this endeavor is creating a robotic sunlight tracker system in harnessing solar radiant to its optimum potential in the Philippine setting, where sun’s insolation is low on the average due to the factors affecting climate conditions (like temperature, rainfall, storminess, winds, etc.).The study developed a prototype robotic sun tracker that is operated by a microcontroller using the sun’s perpendicularity and shadowing techniques in the design of the mechanism that injected an intelligent comparator algorithm. A motor control method was used to execute the best turn to harness the optimum solar energy with an Arduino based monitoring system that measured the voltages obtained from each of the set-ups. The result was a 29% improvement in generating electricity using the robotic sun tracker system versus static panel installation.
ABSTRACT. To eradicate water pollution, a local government in the Philippines has implemented a water rehabilitation project called -Adopt-A-River Project. The project mobilized the local communities to preserve and maintain a clean and safe environment. Promoted through the use of communication media, Adopt-A-River Project has been implemented along the three main tributaries of the area. This study was designed to propose a model of participation considering the level of awareness and perception on the project and the level of participation of the 327 residents. Data were gathered using a validated researcher-made questionnaire with reliability index of 0.970 on perception items and 0.897 on level of participation. Data revealed that local group discussion (52%) is the most commonly used medium of communication in increasing awareness of the project. This is in addition to radio, television, newspaper and the internet. The use of different media resulted in the respondents being informed of the project which led to their involvement in decision-making and consultative role. The information about the project was disseminated using words that are simple and easy to understand. The project was accepted by the residents and participation was heightened. The perception level has an effect on the information level by 0.737. Path analysis using 14 variables showed a good fit with Chi-square = 0000 and GFI, NFI and CFI having values of 0.99 and RMSEA of 0.026. Significant predictors of participation are perception (p=.000) and awareness (p=.000).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
