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.
Policy Brief on Net Metering of Renewable Electricity in Nova Scotia Feb-2016
By Nova Scotia energy professional and longtime Solar Nova Scotia Member Shawna Henderson:
OK, the time has come to debunk this. People are going to die. They will be cold, asphyxiated or burned to death.
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.
Its a busy weekend for Solar Nova Scotia!
Friday April 5: Sup & Share with the Friends Of McNabs Island Society
Boardmembers from the Friends Of McNab's Island will be at our regular Solar Sup & Share to talk about solar options for the McNab's Island Tea House. You are invited to join us to make and hear suggestions about this project. Here's a link to their request: http://solarns.ca/node/70
The Solar Sup & Share is as always at the Lion's Head Tavern on Robie Street near Young, from 5:00 - 7:30.
In January 2013, Solar Nova Scotia released its recommendations to the provincial government for an electricity feed-in tariff.
"The Feed-In-Tariff or FIT, proposes a contract between Nova Scotia Power and a power producer," says Richard Vinson, chairman of Solar Nova Scotia, "For solar and any other renewable energy production to be practical, the producers have to get a fair price for the power they generate."
Ontario has had a feed-in tariff for renewable energy since 2006, and Germany has had an extremely successful program since 1990.
