Bonding and Grounding of Photovoltaics

By Jeff Harrop

Ground is the earth and where voltages over 50 volts must be referenced from. This includes DC (Direct Current) and AC (alternating current) voltages. In order to do this we have a connection to the earth for each power system installed on a premise. It can be a set of driven rods, a plate, the copper water piping system, or a well casing.

The photovoltaic panels have lethal potential voltages and therefore must be bonded to the grounding system to protect people from live voltages from energizing the metal framework of the panels.

All About Inverters An inverter is just a DC to AC converter. Why do we have them in solar applications? Solar PV (photovoltaic panels produce DC (direct current) electrical energy. In our homes and businesses we use electrical devices that take their energy from an AC (alternating current) source.
Why tealights and flowerpots will NOT work Tealights don't significantly heat you or the space you're in. People are going to die. They will be cold, asphyxiated or burned to death.
Largest Solar Installation In Nova Scotia Completed In Sydney

Image removed.On May 15, 2015, the largest ever photovoltaic system in Nova Scotia was commissioned as part of a Sydney home.

This system will generate up to 23,000 kWh of power annually - enough to supply almost all of the home's needs.

Q: Would you be able to stack net metering with CONFIT?
A: No - they wouldn't stack with FIT. In a large site, sure, you could stack them all.

Q: Is the scope of CONFIT looking at a large mix of ground level and rooftop?
A: Yes, generally.
