Solar power is basically a way of converting the radiant energy from the sun into more usable forms such as thermal energy and electricity. Radiant energy is so intense that even the low levels that penetrate the earth’s ozone layer still greatly exceed any possible energy that could be generated from all of the earth’s resources such as coal, gas and oil, combined into one. In 2005 it was estimated that the sun provided a continual source of energy to the earth of up to as much as 170,000 terawatts, which is far more than the entire global consumption was estimated at for the whole year.
Solar energy can be harnessed through a range of technology, the most common of which is photovoltaic solar panels. These panels are made up of solar cells, which contain the semiconductor material silicon. When silicon absorbs solar radiation some of its electrons are knocked free, which then form together into a type of current. Metal conductors placed throughout the solar cells collect the electron current, and channel it away to be used as electricity. The amount of power collected from these photovoltaic solar panels depends on the internal voltage of the cells and also the amount of solar radiation being absorbed.
Large scale commercial solar power is produced through the use of CPS technology, which involves using dish and mirror constructions to capture the solar energy and concentrate it intensely into high temperature thermal energy. This is then used to power steam generators, which convert the thermal heat into electricity and is a low cost technique, with relatively no harmful emissions or polluting by- products.
Power from the sun can of course only be harnessed during the day, and with current technology even a small amount of cloud cover or shading can dramatically reduce energy production. This is why it is important to store solar energy during optimum days of uninterrupted direct sunlight, so that it can be used at other ‘down times’. Although solar energy is a renewable and environmentally friendly resource, the batteries needed to store solar power from sources like photovoltaic solar panels are expensive and contain toxic materials that pollute the environment, and also have to be replaced every few years.
With current technology it is not always possible to heat a busy home solely with solar power, especially considering the amount of electrical devices and appliances the modern household contains. Most of the solar panels systems in domestic settings are mainly used for heating water for both central heating and washing/bathing, and some people also use solar power to heat private swimming pools. Solar power can help reduce your reliance on conventional energy sources, and also save you money on your annual electricity bills.

Solar energy is received in the form of electromagnetic radiations (solar radiation or electromagnetism) and is very important to sustain life on Earth. It helps to grow plants, provides heat and generates solar electricity. In this article, we will discuss the advantages of solar energy as an alternative energy solution. The amount of energy we receive from Sun everyday is 35000 times more than our total energy production and consumption. This enormous source of energy brings many green advantages. Some of these advantages are stated below:
Free of cost:
Solar energy is free of cost. It does not require any fuel. Moreover, it is maintenance-free. It can be a cheap alternate energy solution given the increasing price of gasoline and fuel.
Infinite Resource:
Sun is a constant producer of solar energy. Earth is receiving this energy all the time. Therefore, this never ending energy source is copious.
Environment Friendly:
Global warming is an important issue these days. Solar energy does not burn any fossil fuels. It is the cleanest form of energy. Best of all, it does not produce hazardous gases like carbon dioxide, sulfur dioxide, and methane.
Dependency:
It reduces dependency on power monopolies and power grids to function. Therefore, it is beneficial for remote areas having no power grids. Countries can establish solar plants anywhere.
Save Money:
There is an initial cost of setting up a solar panel but this is a one-time fee with no future bills to pay. You can save lots of money on energy bills. The number of solar photovoltaic systems are rising 50 percent annually. Some solar energy solutions include solar panels, cookers, stoves, ovens, and hot water tanks. You can also sell back excess solar power to your grid.
Affordable:
Federal and state governments offer incentives for using solar energy. Energy Policy Act of 2005 provides options to receive tax credit from federal government. Hence, you are eligible for 30 percent of the system cost for either solar water heating or solar photovoltaic electricity.
Health Costs:
It reduces health risks. Use of diesel or patrol to generate electricity can cause respiratory diseases and have adverse affects on eyes as well. Also, gas and petrol used for vehicles is a major source of pollution. We can use solar powered cars to reduce pollution.
