The 2003 the Northeast blackout affected 45 million people in eight US states. Those using alternative sources of energy such as solar panels were able to benefit from their independence from the grid. No food going bad in refrigerators, no sitting in the dark for them. The Council on Foreign Relations, a think tank, has reported that electricity consumption and production have consistently expanded, resulting in an increased burden on a system not designed for such a large load, meaning that many people are turning to solar panels for security as well as financial and environmental reasons. website
Solar power is a “green” and renewable power and doesn’t emit harmful carbon dioxide, which means it’s a great way to reduce your carbon footprint. Close to 3000 pounds of CO2 per year can be saved by a typical home solar energy system, which works out to about 30 tons over its lifetime. These clean, green technologies will be the core of the next industrial revolution, according to Tony Juniper, Friends of the Earth director.
The use of solar power drastically reduces electricity costs, and this is one of the most common reasons for choosing it. Federal and state governments offer solar incentives, which help to offset the initial expenses of a solar energy system. The 2005 Energy Policy Act provides two ways to be given a solar energy tax credit from the federal government. Solar energy rebates are also offered by more than 50% of US states.
An average of 164 watts of solar power per square meter is delivered to the Earth’s crust by the sun. If we placed enough solar panels in the Sahara desert to cover just one percent of it, we could generate enough electricity to power the entire planet. This abundance of solar power means there’s more than we’ll ever need. But because the power sent out by the sun arrives as a mixture of light and heat, we can’t use it as it is to directly power a car or a computer. This is why solar panels were invented – to convert the sun’s power into a form we can use, like electricity.
Any extra electricity you create using your solar panels, if you’re attached to the grid, will be paid for by the utility company. Accounting for a solar energy system’s electricity production and enabling utilities to purchase excess energy from homeowners, net metering is allowed in 30 states. The most frequently used option is a single, reversible meter. As a solar energy system produces electricity, the kilowatts are used first to meet on-site energy demand. Excess electricity is then fed into the grid, turning the electric meter backwards, instead of being stored in a battery. The homeowner is credited for the extra kilowatts at the end of each metering period.
