What is the role of supplemental electrical supply systems?

The role of supplemental electrical supply systems encompasses enhancing existing electricity sources, which is effectively achieved through photovoltaic (PV) systems. These systems harness solar energy and convert it into usable electrical power, thereby supplementing traditional electricity sources that may have limitations in capacity or sustainability. By utilizing PV systems, buildings can benefit from renewable energy, reduce dependency on grid electricity, and potentially lower energy costs while also contributing to environmental sustainability.

While the option of providing backup power during emergencies is often associated with supplemental power systems, the primary function of PV systems within this context emphasizes their role in enhancing and diversifying energy sources rather than solely serving as a backup. Therefore, the correct focus is on the integration and enhancement of existing electrical supply systems through the use of renewable energy technology.
