Clean energy is gaining grounds rapidly just when greenhouse gases and carbon emissions are immensely hurting our ecosystem. Nowadays, it has become common place to use solar power not only in commercial unit but also for residential purposes. Gladly enough, the unit cost of solar power installation has steadily dropped but, could even drop further if we have the capacity of setting up the installation which overall, can help keep the acquisition within budget. In this study, we present a practical approach to proper energy management on hoe to install a solar power unit in a one-bedroom apartment housing essential house-hold equipment. The set up comprises of the four basic solar power ingredients namely, solar panels, charge controllers, inverters, and a bank of batteries. Additionally, we included a circuit breaker, meter, MC4 connectors and fuses. Although there are smart solar panel calculators that could determine the choice of the components, the design method used in this application is to manually take the raw calculations based on load requirements. This method presents an ideal guide to installers who can either ill-afford the smart tool or are not familiar with its usage.
