How Solar PV System Works With Your Home

Solar power generation converts sunlight into electricity using photovoltaic (PV) technology or solar thermal systems. Here’s a step-by-step breakdown of the most common method—solar PV systems.

Sunlight Hits Solar Panels

  • Solar panels are made of photovoltaic (PV) cells, typically from silicon.

  • When sunlight (photons) strikes these cells, it knocks electrons loose, creating an electric current (DC electricity).

DC Electricity is Generated

  • The PV cells produce direct current (DC) electricity, which flows to an inverter.

Inverter Converts DC to AC Electricity

  • Most homes and businesses use alternating current (AC), so an inverter converts DC to usable AC power.

  • Microinverters (per-panel) or string inverters (centralized) can be used.

Electricity Powers Your Home/Business

  • The converted AC electricity flows into your electrical panel (breaker box) and powers lights, appliances, and devices.

  • Any excess electricity can be:

    • Stored in battery systems (like Tesla Powerwall) for later use.

    • Sent back to the grid (if net metering is available, earning credits).

Grid Connection

  • Grid-tied systems feed surplus power back into the utility grid, reducing your electricity bill through net metering.

  • Off-grid systems rely solely on solar panels + batteries (no grid connection).

Monitoring & Maintenance

  • Solar monitoring systems track energy production in real-time.

  • Minimal maintenance is needed—occasional cleaning and system checks ensure efficiency.
