3 A brief overview of solar energy is required in order to make sure the over all concept of todays presentation is understood

4 Solar Energy Solar energy is a renewable resource that is free, readily available, environmentally friendly and necessary for all life on earth. Solar energy can be used in many ways - to provide heat, lighting, mechanical power and electricity, which is what we are focusing on here today.

5 Photovoltaics (PV) dc electricity is generated from sunlight by using photovoltaic (PV) solar cells. dc electricity is generated from sunlight by using photovoltaic (PV) solar cells.

6 These cells are semiconductor devices, usually made of silicon, which contain no liquids, corrosive chemicals or moving parts. The PV panels require little maintenance, do not pollute, and operate silently, making photovoltaic energy a very clean and safe method of power generation.

11 Using an Inverter, the DC electricity from the Solar PV is converted to AC, then its fed through a meter, in the case of FIT, to measure the amount produced, and then it is all sold to the grid.

17 What is a Feed in Tariff? Basic terms – you generate renewable electricity, the Ontario Power Authority buys it from you through your Local Distribution Company.

43 Summary By promoting the use of renewable energy to produce clean electricity, we are able to generate income, reduce harmful emissions and create jobs. By coming together as a community we will enable individual non-profit organizations to achieve these goals more easily and sooner.
