above shows a residential Grid-Connected
Photovoltaic System.
1. Solar panels
2. Inverter
3. Breaker box
4. Home power and appliances
5. Meter
6. Utility power grid.
1) Solar Electric or PV modules convert
sunlight to electricity. The PV modules
generate DC electricity - or direct current
- sending it to the inverter.
(2) The inverter transforms the DC power
into AC electricity for ordinary household
needs.
(3) Existing electrical panel distributes
solar electricity and utility power to
(4) loads (appliances). For systems with
a battery backup (optional), the inverter
also regulates the charge of batteries.
The electricity stored in the batteries
can be used at night or during blackouts.
