Solar Power

From http://www.eia.doe.gov/cneaf/solar.renewables/page/solarreport/solar.html While demand for solar continued to grow in 2006, the supply of high-grade silicon used to make PV cells continued to impact the solar industry. Two types of solar companies are expected to perform well in this market. First are the silicon-based solar manufacturing companies that have secured stable silicon supplies. Second are the companies that focused on thin-film solar technology (thin film solar modules use either a very thin coating of silicon or other alternative materials with no silicon). Not surprisingly, thin-film PV cell and module shipments experienced the greatest percentage gain between 2005 and 2006, nearly doubling. Still, conventional crystalline silicon cells and modules shipments continued to dominate all PV technologies with 233,518 peak kilowatts shipped in 2006. However, its market share continued to decline to 69 percent from 76 percent in 2005 and over 95 percent a decade ago (Table 2.21 and Figure 2.8). Within this category, single-crystal shipments rebounded to 85,627 peak kilowatts, or slightly more than 25 percent of total shipments in 2006, compared to 71,901 peak kilowatts in 2005. Cast and ribbon silicon shipments, the predominant PV technology, rose sharply to 147,892 peak kilowatts in 2005, or nearly 44 percent of total shipments, compared to 101,065 peak kilowatts in 2005 (Table 2.21). Today, thin-film PV modules that use materials such as amorphous silicon (a-Si); cadmium telluride (CdTe); or copper indium gallium selenide (CIGS) are attracting much attention and are growing at an impressive rate, in part due to the shortage of silicon and high manufacturing costs associated with crystalline silicon cells. With the help of lower manufacturing costs and its versatility, thin film technology has ignited the competition with conventional crystalline silicon technology over the past couple of years. However, thin film modules are typically much less efficient than crystalline silicon modules with 7 to 10 percent efficiency compared to silicon's average 15 percent efficiency.

Any manufacturing process tends to be detrimental in some way. In energy terms the cells pay for themselves relatively quickly (between 2-4 years now), but there are other environmental costs associated with production such as chemical waste.

However the net affect is definitely positive.

PV solar power refers to the generation of electricity using photovoltaic (PV) cells, which convert sunlight directly into electricity. This renewable energy source is commonly used in residential, commercial, and industrial applications to reduce reliance on traditional fossil fuel sources and lower greenhouse gas emissions.

During photosynthesis, the chloroplasts use sunlight and water to produce glucose, a sugar used for food. (By making its own food, this plant would be an autotroph.)Once the lighte energy is converted into fuel energy, the cell may use it, or it might be taken to the mitochondria, which then convert it into chemical energy for the cell to use.

-40 centigrade is the temperature which is equal to -40 Fahrenheit and vice versa.

Recent research has shown that solar energy provides a wide range of benefits. These advantages include geopolitical benefits, labor-intensive production regimes, minimized environmental impact, healthy financial incentives, and less reliance on public utility service providers.

Double glazing is better at stopping heat escaping because it consists of two panes of glass with a gap filled with gas, creating an additional barrier for heat transfer. This design insulates better than single glazing, which only has one pane of glass providing less resistance to heat loss.

There are several factors that make wind power bad. First of all, the initial cost of setting up is so high and winds may be unpredictable which makes this form of power unreliable among other factors.

Yes, wind power is an effective source of renewable energy. Wind turbines convert the kinetic energy in the wind into electricity without producing greenhouse gases or other pollutants. However, the effectiveness of wind power can vary depending on factors like location, wind speeds, and infrastructure.

When you combine batteries in series, the voltage increases but the amp-hour capacity remains the same. So, combining four 6V batteries with 220Ah each in series to create a 24V battery bank will still result in a total capacity of 220Ah.

Yes, solar panels do work but it depends what you are using them for. A lot of solar panels are for toys etc and they would be small. But there are solar panels suited, being larger, for industry or residential.

the most familiar form of energy is chemical energy. every human uses chemica energy to digest their food into fuel that gives them energy to move around.

a photovoltaic effect is the affect when electromagnetic radiationfalls on a thin film of one solid deposited on the surface of a dissimilar solid producing a diffence in potential between the two materials

Solar energy can be expensive due to the initial cost of installing solar panels and associated equipment. Additionally, the technology used to capture and convert solar energy into electricity can be expensive to produce and maintain. As technology advances and economies of scale improve, the cost of solar energy is expected to continue decreasing.

To stop a fire, you can use a fire extinguisher, water, or a fire blanket. Make sure to follow proper safety procedures and aim at the base of the flames to smother the fire. If the fire is too large to handle, evacuate and call emergency services.

Solar power is a popular renewable energy source because it is abundant, free, and non-polluting. Solar panels convert sunlight into electricity through photovoltaic cells, making it a clean and sustainable alternative to fossil fuels. Additionally, solar power can be harnessed in both large-scale solar farms and small residential installations, providing flexibility and accessibility.

The amount of power you get depends on a number of factors, including the efficiency of the solar panels.

Ideally, the energy of sunlight would be about 1366 watts per square meter, but losses do to such things as the atmosphere reduce this to a practical limit of about 1000 watts. If a solar panel of one meter is 10% efficient, then this means you would get about 100 watts. New technologies are achieving efficiencies approaching 50%, which would produce 500 watts; but some older panels were only 6% efficient.

Since you ask about watts, I am assuming you mean photovoltaic panels. Solar thermal collectors are more efficient, but do not produce electricity.

People can get energy from sunlight through a process called photosynthesis, which is carried out by plants, algae, and some bacteria. During photosynthesis, these organisms convert sunlight into chemical energy in the form of glucose, which can be used for various cellular functions and to produce ATP, the energy currency of the cell.

The instrument in solar panels that converts light energy to electrical energy is called a photovoltaic cell, also known as a solar cell. This cell is made of semiconductor materials that absorb photons of light and generate an electric current through the photovoltaic effect.

Solar power is renewable because it is derived from the sun, which is an abundant and inexhaustible energy source. The sun continuously produces light and heat, allowing for solar panels to convert sunlight into electricity without depleting the source itself.

The cell structure determines the way solar energy is captured. Mono cells are good for direct sunlight, while Poly cells are good for indirect sunlight. As an example you would use mono cell on top of your roof, while you would use poly cells on the side of your house.

Heat helps to dissolve sugar faster in water by increasing the kinetic energy of the sugar molecules, causing them to move more rapidly and interact with the water molecules more effectively. However, excessive heat can also lead to the caramelization of sugar, changing its flavor and color.

Solar panels produce electricity through the photovoltaic effect, where sunlight is converted into electricity using semiconductor materials like silicon. When sunlight hits the solar panels, the photons in the light knock electrons loose from their atoms, creating an electric current. This current is then collected and converted into usable electricity for powering homes or buildings.
