Abstract

Solar-powered and direct current energized households can be a smart choice in resorting to renewable energy. The cost of electricity continues to rise due to the rising cost of fuel used to generate electricity, depleting sources of fuel, and the adverse effect of some energy sources used to generate electricity. A survey on household's selected electrical parameters, development, and testing of a strategy of shifting and converting the lighting system of households from 220 volts alternating current (AC) to 12 volts direct current (DC), and solar was conducted. The results showed that the majority (53.85%) of the households' lighting system can be converted and the conversion strategy is technically feasible. The solar and DC lighting system also projected a savings of 326.70 pesos per month, with an estimated ROI of 27.6 % and a payback period of 3.62 years under the Philippine conditions. The shifting or conversion strategy showed excellent potential as an alternative lighting system not only for households but for other applications.
