Different types of electric generation and various ways in harnessing useful energy are now in demand to reduce the cost of electricity. This is due to growing concerns that lead to the global search for renewable energy resources. The researchers came up with the prototype combining the technology of solar power generation and wind power generation in order to provide an uninterruptable source of energy for a single dwelling unit. The electrical system is composed of a solar panel and a wind turbine controlled by a relay that serves as an Automatic Transfer Switch that would manage the uninterruptable distribution of energy to a storage battery and through an inverter to provide continuous power to the single dwelling unit also built by the researchers. The solar panel already has a built-in system designed to have 100 watt power output and 12VDC voltage controlled by a charge controller to manipulate the ampere needed in the system. While in the wind turbine, the researchers used a permanent magnet motor while the propeller was made of PVC pipes and chains and sprockets was used to connect it to the alternator. The researchers found out that the prototype is effective when it comes to providing uninterruptable power supply, with ease of maintenance and operation supplying uninterruptable power on listed load based from the survey done by the researchers from the people living in a single dwelling unit near coastal areas.
