How are solar cells today superior to solar cells of the 1980?
Advances in technology - coupled with the discovery of more efficient materials, make today's solar cells much more efficient than earlier models.
What do solar panels have in them?
Solar panels are a series of cells connected together.Also you can make your own solar panels because today some manufacturers sell the cells individually.I bought a DIY Guide that helps me make my own solar systems at a fraction of retail prices.If you are interested the site can be reached by using the Related Link shown below.
What is the purpose of solar panels?
Solar energy is the radiant light and heat from the Sun that has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation along with secondary solar resources such as wind and wave power, hydroelectricity and biomass account for most of the available renewable energy on Earth. Only a minuscule fraction of the available solar energy is used. Solar power technologies provide electrical generation by means of heat engines or photovoltaic. Once converted its uses are only limited by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, day lighting, hot water, thermal energy for cooking, and high temperature process heat for industrial purposes. Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute sunlight. Active solar techniques include the use of photovoltaic panels, solar thermal collectors, with electrical or mechanical equipment, to convert sunlight into useful outputs. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air. The sun has produced energy for billions of years. Solar energy is the sun's rays (solar radiation) that reach the earth. Solar energy can be converted into other forms of energy, such as heat and electricity. In the 1830s, the British astronomer John Herschel used a solar thermal collector box to cook food during an expedition to Africa. Today, people use the sun's energy for lots of things such as heating houses, providing energy for cars, and, and having it as an extra energy source Heat water - for use in homes, buildings, or swimming pools. Heat spaces - inside greenhouses, homes, and other buildings. After the 1973 oil embargo, there was a resurgence of interest in solar energy. Faced with a possibility of scarce oil resources, the United States government allocated $400 million per year, from a mere $1 million per year, for solar energy research. The expenditure is small compared to the expenditure on nuclear research. Currently, there is a need for allocating increased resources in solar research. Compared to the old forms of depletable energy (coal, oil, nuclear), solar energy offers a clean renewable form of energy. This presentation will provide an overview of the past, present and future of solar energy. # The purpose of the solar panel is to capture energy from the sun and to turn this energy into electrical energy. The electric motor then uses this electrical energy to power the wheels of the solar car.
Why is solar energy used widely today?
Solar energy is used more because Al Gore made all the liberals believe that global warming is an actual threat to the earth. It is fact that more scientist know that global warming is not a real problem. ^THIS IS NOT TRUE BUT JUST A PILE OF BULLSH*T^
What is the disadvantage of using solar cells?
The major disadvantage of solar power or solar energy is the cost of the photovoltaic panels. The location of your home in relation to sunlight, how many hours per day of sun you receive, and the amount of energy you use monthly determines the size of the photovoltaic panels. Estimates range between $7--10 per square foot for photovoltaic panels. The average price for a home is typically around $20,000 and can be much higher. Ahead of the curve companies are starting to provide more reasonably priced options, as they see the value in making solar home energy affordable and available to wide range of the public. Local and state governments are working hard to help offset high costs with subsidies, tax breaks, and tax credits. However, the average cost remains relatively high a home with solar panels is going to pay around 30 cents per Kilowatt hour after you factor in the cost of the solar panels, compared to a home on the electrical grid that pays around 9.5 cents per kilowatt hour. As you can see, photovoltaic panels cost three times as much per kilowatt hour. Another disadvantage of solar power is the fact we do not have the technology to use solar panels effectively in places without ample sunshine. Most of us don't live in sunny places like Florida, Hawaii, or portions of California. The majority of people live in areas that are seasonal and when daylight hours are shorter, the amount of energy solar power panels can produce is limited or nonexistent. Without the sun, solar panels are useless because there is no "solar power." There are ideas floating around about building solar power towers. These solar power towers would work much in the same way our current electricity producing plants work today. They would be in a centralized locale and provide energy to the surrounding area. Unfortunately, the idea is still in its early stages and the projected cost is extremely high. Although the disadvantages of solar energy are undeniable at this point, there is ample reason to have hope for the future. The interest in alternative energy and specifically solar energy is growing, and as more people demand this technology, the more that funding and research will increase.

solar land.
What kind of energy output per dollar invested can a consumer expect from solar energy installations today?
Recent advances in solar energy harvesting technology have made great leaps in the efficiency of solar cells. This has led to more widespread availability, and even government refunds for the majority of the cost of installing solar panels.
Are there Russians in America today?
There are certainly Russians in America today. in the 1980s the USA was in a conflict with Russia known as the Cold War.
Is solar cell a fossil fuel?
No. Solar cells convert solar energy into electricity. The main fossil fuels used today are natural gas, oil and coal and are taken from underground deposits. The energy produced by a solar cell is not fossil fuel based, however the materials used to produce the cell, many, are fossile fuel based.
