Solar power generation is only solar energy, but it is Ontario\'s most attractive energy source.
Traditional solar panels are made of two silicon crystals.
When light shines on silicon, it hits electrons released from the negatively charged plate at the top, creating a current flow to the positively charged plate at the bottom.
Current is transmitted to a device called a inverter.
Because the original process is direct current, converter is needed, so it must be converted to alternating current for use in power supply network.
New technologies have developed solar panels that can be rolled up, spread out and nailed to roofs.
At MIT, scientists have developed solar cells that can be printed on paper.
Industrial-scale solar panels have tracking devices that rotate the panels to align directly with the sun as they pass through the sky.
To achieve maximum efficiency, roof panels need to be as close to the South as possible.
As the Ontario government is reviewing the price of renewable energy, the economic situation of solar panels is changing, and the cost of solar panels is declining.
One installer said that a year ago, installing a 10-kilowatt roof solar panel cost $70,000 and earned $9,000 a year.
Now it\'s worth 50,000 dollars.
Chris Stern of Pure Energy said that the rule of thumb in an industry is to install a solar panel, a small roof panel, at a cost of $6 per watt. a set-
At current prices, electricity over 5 kW will cost $30,000 and annual revenue will reach $3,800.
His company will sell and install solar panels, or pay the homeowner a fee to get the right to install solar panels on the roof and collect income.
Industrial-scale solar facilities benefit from economies of scale, slightly reducing the cost per kilowatt.
However, real estate and other costs vary greatly in different locations.
Ontario\'s domestic demand for solar installations will also drive up costs.
Sun Edison just started building a 10-
At the Megawatt Solar Farm near Ingerside, 42,000 solar panels cover 90 acres and are powered by Ontario. -
In the tariff plan.
It is estimated that 300 million kWh will be generated in the next 20 years, averaging 15 million kWh per year.
The matching rate is 44.
Three cents per kilowatt-hour will generate about $6 in revenue.
Six million a year.
That\'s equivalent to more than $73,000 per acre.
By contrast, an acre of corn earns about $860.
