How It Works

• Solar Panels: Convert sunlight instantly into DC electric power.
• Inverter: Converts DC power into standard household AC power for use in the home, synchronizing with utility power whenever the electrical grid is supplying electricity.
• Existing Electrical Panel: Distributes solar electricity and utility power throughout the house.
• Utility Meter: Actually spins backward when solar electricity generation exceeds house electricity consumption, sending power back to the electric utility for full credit at the retail rate it charges you.
• Utility Power: Is automatically provided at night and also during the day when your demand exceeds your solar production.

Off-Grid Solar System

• PV Array: Sunlight passes through the silicone wafers in the PV modules, knocking loose electrons which flow into wires as Direct Current (DC) electricity.
• Combiner Box: The PV modules are wired together in a combiner box to output the correct system voltage (VDC)
• Charge Controller: Controls the voltage going into the batteries and maintains the battery bank charge at pre-programmed limits.
• DC Disconnect: System shut-off with circuit breakers and ground fault protection. Required by code to ensure that all parts of the system can be disconnected from all sources of power.
• Batteries: Batteries store the energy generated by your system during the day for use at night or on cloudy days.
• Inverter: Direct Current (DC) electricity from the PV Array is converted to Alternating Current (AC) electricity to supply the house loads.
• AC Panel: AC loads are connected here with circuit breakers.
• AC Disconnect: AC output from your inverter and AC power from back-up power sources, like generators, if used, are combined here with circuit breakers.
