How does solar electric work?

Sunlight strikes a semi conductor material and bumps electrons off in a continous stream called direct current (DC). Home appliance and lights use alternating current (AC), so it is the job of the inverter to change the DC to AC. If your home is using electric energy (refrigerator/lights on) the solar-produced energy is consumed there. If your solar system is making more energy than your house is using, the surplus gets sent back to the grid, which for accounting purposes acts as a bank. [See hybird & off grid for different explanation]

Considerations

- Panels and inverters must be matched according to the amount of energy your solar panels can generate

- The inverter needs to be close to the panels and has to be connected to your main house electric panel

- For grid-tied solar systems, when the grid is down your system will be automatically shut off until the grid comes back online primarily for safety reasons
