How Solar Works at Home
A home solar system is simple: panels collect sunlight, an inverter converts it into usable power, and your home stays connected to the grid for reliability.
1) Panels Capture Sunlight
Roof-mounted panels convert sunlight into direct current (DC) electricity. They work even on cloudy days, though output is reduced.
2) Inverter Converts DC to AC
Homes use alternating current (AC). The inverter “translates” the DC power from your panels into AC so it can power your lights, appliances, and devices.
3) Power Feeds Your Home
Converted electricity flows through your main panel to power anything running in the house. If your system produces more than you use, the extra energy is sent to the grid.
4) Net Metering Credits
In many states, excess power earns credits on your utility bill through net metering. At night or on cloudy days, you use grid power and draw against those credits.
During a Power Outage
For safety, grid-tied systems automatically shut off during outages. Add a battery to keep essentials running until the grid returns.
5) Optional Battery Storage
A battery stores extra solar energy for nighttime use or outages. Learn more in Batteries & Backup.
6) Monitoring and Maintenance
Most systems include apps to monitor production. Panels need little upkeep—rain often handles cleaning—and inverters typically last 10–25 years.
