From sunlight to the socket in your wall — a plain-English walkthrough of how a rooftop solar system turns photons into the electricity that runs your home.
## The short version
A solar panel converts sunlight into direct-current (DC) electricity using the photovoltaic effect. An inverter turns that DC into the alternating current (AC) your appliances use. Anything you don't consume is either stored in a battery or exported to the grid.
## Follow the electricity, step by step
1. Sunlight hits the silicon cells in each panel and knocks electrons loose, creating a DC current.
2. The DC power flows
down to a solar inverter mounted near your distribution board.
3. The inverter converts DC to 230 V AC and synchronises it with your home's wiring.
4. Your appliances draw solar power first; the grid or battery covers any shortfall.
5. Surplus daytime power flows backwards through a net-metering meter and earns you credit.
## Why it matters in Pakistan
With long sunny days and rising tariffs, a well-sized rooftop system now pays for itself faster than at any point in the last decade. Understanding the basics helps you ask installers the right questions and avoid oversized or undersized quotes.
