Learning The Way Solar Energy Functions

ByLincoln Gartrell

The fact that plants can use sunlight to sustain themselves can seem nearly magical, but recently humankind has developed its own system to work with solar energy. We've progressed far beyond using the sun to simply heat things. Solar energy systems, also called photovoltaic systems, can generate electricity to allow people to run home appliances with solar panels. This is a great option for many individuals not only to save money, but to avoid releasing dangerous emissions in our environment. But how does solar energy work?

The word "photovoltaic" can be split into two parts, with "photo" meaning light, and "voltaic" referencing volts, which are units of electrical force. Putting them together, you get electricity generated by light. Solar panels consist of photovoltaic chips that use this process to create energy for homes. PV chips are almost always made of the material silicon which is a semiconductor, meaning it has a good capacity to release energy when light strikes its surface. This allows for solar panels to easily create energy for a directed purpose within the full scheme of a solar energy system.

The photovoltaic cells in a solar energy system use two layers of semiconductors in order to excite electrons. One layer of cells is positively charged and the other negatively, and so tension is created between them and volts are generated. This is all well and good, but the electricity made when the sun hits a solar panel is in the form of direct current, or DC energy. To change this into something that will be compatible with a normal 240V home appliance, it needs to be changed into alternating current (AC) energy using an inverter.

AC energy tends to be more effective than DC energy. Electrons only flow in one direction with DC energy. With AC energy, electrons continually switch directions in the electrical current, which allows it to be safer (since different amounts of power can be transmitted), and travel longer distances without losing any energy. As described, solar energy systems can generate electricity with an inverter, but they can be supplemented by a city's electricity grid. If you are unable to meet your electrical requirements with solar energy alone, then the grid can provide you with additional electricity for you to seamlessly continue everyday living. Better yet, if you can provide all of your own electricity and still have some left over, it will be fed into the grid and the city will compensate you with cash for the extra energy you've provided.

It's clear to see that the benefits of a solar power system are extensive, and the science behind them is simple and efficient. In case you find the possibility of setting up a solar energy system on your own to be a little overwhelming, many professionals are around to help out with getting a solar energy system installed on your home. In the long term solar panel technology will only grow more sophisticated, and more ways will be found to enhance the usage and amount of electricity people are able to generate. By committing to solar energy and finding out how it can support you, you will be on your way to lowering energy bills and creating a healthier future.

Learning About Non-Organic Solvent Products and Their Dangers

ByTimothy Byron

A solvent can be any liquid or solid that dissolves another solute. Solution products are soluble in certain amounts and under specific temperatures. Many businesses use industrial solvent products to clean parts, machines, and in refinishing processes. Organic solvents have become more common because they are better for the environment. Common examples include dry cleaning solutions, paint thinner, glue agents, detergents, and spot removers. Less intense versions are typically used in the home, while more concentrated cleaners are needed for industrial use.

The evaporation rate of these substances often depends on environmental temperature. A low boiling solvent such as diethyl either will evaporate quickly when a small amount is applied under regular room temperatures. Higher boiling substances must have more intense temperatures, certain airflow, and possibly a vacuum application to evaporate quickly. Flammability is determined by the volatility of the solution. In some instances, the right mixture of these chemicals can cause an explosion. It is important to use appropriate chemicals along with proper handling for prevention of chemical reactions.

Most Used Forms of Industrial Degreasers or Cleaners

Industrial degreasers are common in many work environments. Usage of these solvents is important because their vaporization, flammability, and additional properties can harm those who must use them or work in their general vicinity. Common solvents can be found in various cleaning products. Prolonged exposure to these solutions may cause health problems, such as organ damage or long-term health conditions.

The Environmental Protection Agency regulates use of these substances to protect both the environment and individuals. The harmful effects of cleaning agents have led to organic substitutes that reduce or eliminate the amount of compounds released into the air. Hazardous Air Pollutants are released into the atmosphere and can be inhaled by unsuspecting individuals.

Safe alternative materials exist, and are free of these compounds and are completely benign to the environment. Organic solvents discharge Volatile Organic Compounds that are harmful to people, despite having the organic label. Alternatives with minimal to no VOCs are now available to reduce these effects.

Five common industrial degreasers can be found in business settings. Trichloroethylene is a metal cleaner that can also be used for spot treating. It is not flammable, but the chemical can be inhaled or absorbed into the body. Extensive inhalation may cause heart, liver, and brain problems. Other side effects include nausea or headaches. Perchloroethylene has various applications, with one of the most prominent being dry cleaning. It can also be used as a metal cleaning agent or a lubricant. The synthetic solvent is not flammable, but can be inhaled. Methylene Chloride is a paint-stripping agent that can also clean metals. Isoparaffinic solvent products are fabricated solutions used for degreasing.

These oil-based cleaners are odorless and less toxic, and only extensive exposure causes significant side effects in humans. Finally, modified alcohols can be implemented for metal cleaning or degreasing. The EPA has approved these alcohols as an alternative to other cleaning agents because of their low toxicity. Prolonged exposure to any of these substances is dangerous. Businesses can purchase organic alternatives that are both safer for their workers and cost effective.

Solvent products are used for various types of business cleaning applications. Industrial degreasers may be replaced with safer alternatives such as organic cleaning agents.
