How Solar Energy Systems Work
Solar energy systems convert sunlight into electricity using photovoltaic (PV) panels. These systems are designed to power everything from lights and appliances to entire buildings. Here’s a basic breakdown of how a typical setup works:
? Components of a Solar Energy System:
Solar Panels (PV Modules)
Capture sunlight and convert it into direct current (DC) electricity.
Inverter
Converts DC into alternating current (AC) for home or business use.
Mounting System
Secures panels to your roof, wall, or ground.
Battery (Optional)
Stores excess power for nighttime or emergencies (off-grid or hybrid systems).
Net Meter (For grid-tied systems)
Measures electricity imported from and exported to the grid.
⚡ Types of Solar Energy Setups:
Grid-Tied: Connected to the public utility grid; most common in cities.
Off-Grid: Fully independent; ideal for rural or remote areas.
Hybrid: Combines grid access with battery backup.
Fun Fact: One square meter of solar panel in the Philippines can generate up to 4.5–5.5 kWh/day — among the highest yields in Asia!
