Grid-tie PV Solar System Basics
Sunlight to Electricity
Photovoltaic technology converts sunlight into electricity and is emerging as a major power source due to its numerous environmental and economic benefits and proven reliability.
Enough free sunlight falls on earth to supply our energy needs for years to come.
Environmental Benefits:As PV generates electricity from light, PV produces no air pollution or hazardous waste. It doesn't require liquid or gaseous fuel to be transported or combusted.
Economic and Social Benefits:Sunlight is free and abundant. Photovoltaic systems allow you to generate electricity and sell it to the grid. This energy source is free, clean and highly reliable. PV systems are long-lasting and require little maintenance. The benefits of Photovoltaic far outweigh the initial cost the systems.
Photovoltaic System
A complete system includes different components that should be selected taking into consideration your individual needs, site location, climate and expectations. In this section we review the components' function and several different system types.
Major System Components
The grid-tie PV system consists of several components.
PV Modules - convert sunlight instantly into DC electric power.
Inverter - converts DC power into standard AC power for use in the home, synchronizing with utility power whenever the electrical grid is distributing electricity.
Grid Connected
Grid-connected or utility-intertie PV systems are designed to operate in parallel with and interconnected with the electric utility grid. The primary component is the inverter, or power conditioning unit (PCU). The inverter converts the DC power produced by the PV array into AC power consistent with the voltage and power quality required by the utility grid. The inverter automatically stops supplying power to the grid when the utility grid is not energized. A bi-directional interface is made between the PV system AC output circuits and the electric utility network, typically at an on-site distribution panel or service entrance.
Ontario FIT Program
The Ontario microFIT program allows you to get paid to generate solar energy at home or
work and sell it to the electricity grid.
Under the microFIT Program, you will be paid a guaranteed price over a 20-year term (40 years for waterpower projects) for all the electricity you produce and deliver to the provinces electricity grid. The prices are designed to cover the costs of a typical project purchase, installation, connection, operating and maintenance and to allow you to earn a reasonable rate of return on your investment.
