Applications and its work

Storing the energy generated from heat and light makes these PV cells work more reliable. They save the power and then reused when needed. These PV cells are used in switches, telephones, television and almost every electric equipment. A physical process called the photovoltaic effect is actually the change of the energy from sun-light into electrical potential energy by a photo voltaic cell(solar cell). Photovoltaic cells are used to in situations where they are more profitable than other power generation methods. Sometimes, they are used as photo detectors.

The photovoltaic cells store the heat and light which comes from the sun and make it useable in place of electricity. These PV cells can also be used in street light as they save all the energy in day light and then make it workable in night for longer period and the major character tics of this PV cells is that it stores the energy and then make it reuse as an alternative of electricity. Another method is used to increase the amount of electricity which is being generated by PV cells is that the huge amount of silicon layers are combined together from what the are called PV arrays. These PV arrays are mostly used to power the electric equipment in homes and offices. They are very much useful in supplying power or electricity to the remote places where there is no source of generating electric powers. The PV cells are useful because it stores all the power which comes from sun in form of heat and light and then this power is saves in these cells and then it used in night and cloudy whether because at night there is no sun light and in cloudy whether the sun light is dim, but these PV cells have the quality to save that power so that it can used be used in contingency. The PV cells are different from these cells because the PV cells have more storing and long live capacity on the other hand the disposable cells have shorter life and they don’t have long storage capacity.

Solar photovoltaic’s global market trend

As we know that the world have recognized that the best alternative of fossil fuel is solar energy because it have many advantages and less side effects because of which the trend of PV has came in global market. The manufacturing of PV is increasing as according to latest report that its manufacturing is almost reaching 48 percent average per year since 2002 and it has turn out to be the world fastest growing energy technology. Rough approximation says that almost 90 percent of generating capacity is consisting of grid-tied electrical system. This type of installation can be ground mounted or it can be on roof tops or walls and it have a particular name called building integrated photovoltaic or for in short terms BIPV.

Photovoltaic is the field of technology which tells that how the application of solar cell is utilizing light and heat from the sun in the electricity form so that it can be used as an alternative to the electricity which is being formed from fossil fuel.

Photo-voltaic’s or simply PV is the procedure of constructing electrical power by changing solar radiation into direct electricity utilizing semiconductors that show the photovoltaic’s effect. This power generation is prepared from solar panels which are consisting of number of cells which are prepared from photovoltaic things. The thing which is utilized in photovoltaic is monocrystaline silicon, polycrystalline silicon, amorphous silicon, and cadmium telluride and copper indium selenide.

SOLAR ENERGY JOBS

Solar energy is the energy that comes from the sun. Every day the sun gives an enormous amount of energy to the earth. The sun emits amount of energy in one second more than people have used from the
beginning of life on earth.

The solar energy use has been increasing day by day automatically it is causing an increase in the jobs related to solar energy and a large number of labors source is needed in this newly born field. By using fossil fuel as an energy source a lot of air and water pollution is caused. So in order to avoid air and water pollution the companies as well as home investors prefer solar energy.

Solar energy is converted either into thermal energy or electricity.

• Solar thermal energy
It is used to heat different structures such as homes, buildings, greenhouses and pools.

• Electricity
Solar energy can be changed into electricity by of two methods
• By using solar cells to change sunlight into electricity
• By a solar power plant that uses solar thermal collectors to create steam that is further used to run generators.

Solar Energy Education

Most of the professionals who work in solar energy industries obtain qualifications in the related fields (sciences, engineering or business disciplines. No specific qualifications are needed for getting a job in solar energy industry. That is why training is provided by the employer. But the qualifications are preferred comparatively between the employees. The previous experience jobs are also considered.
For entering into a solar power industry a student can have an educational background from engineering, branch of earth science or a technical field. Many universities are now developing solar power programs in their respective renewable energy departments. As the solar power industry is flourishing its causing an increase in number of students opting solar power studies.

Solar power careers
It is a type of industry in which an individual can enter only if he has high school education as an installer and can work hard to reach unto the level of a technician. So the higher level positions (engineers, managers) require educational backgrounds in the subjects of engineering, physics, the earth sciences or management.

Solar Power Project Manager
The job of a project manager is to act as the overseer of the solar power site. Experience in all aspects of solar power operations is required for this job. This post requires advanced degree but bachelor’s degree in physics, engineering, field of earth science, and experience in industry is also accepted.

Solar Power Engineers
A solar power engineer has to design and develop solar energy systems on a solar power farm. Solar engineers play an important role in solar power operations, system development, troubleshooting, and research and management duties. Engineers must be certified and licensed.The solar engineers should have engineering degree or an educational background in physics. Preferrence is given to employers on the basis of previous job experience

Solar Technicians
The work of solar technicians is to examine and inspect solar systems. Technicians have to install solar systems, do service and repair duties. In this category experience is preferred as compared to education. The technicians have to spend 2 or 3 years as installers to gain experience after that they are being promoted.

Solar Installers
The job of a solar installer is to do the electrical wiring and mounting of the system. Here also experience in wiring, residential electrical installation, construction is more important than education. Solar installers are usually paid on the hourly basis ranging from 14-20 hours a day which depends on experience and location.

Solar panel mounting

Solar Panel Mounting Fossil fuel is the biggest source of energy being used from many decades that is the reason it has become short many people are beginning to look for alternative sources for energy. At first they have looked on coal because our earth is full of coal reserves and they are not used that much but at last after research they have find out although coal can be main source of energy but it have many side effects in which the main one is pollution and it can cause damage to ozone layer. Then on second option they have found out that’ solar energy means sun light can be utilized in alternate to fuel based energy production. Sun is the greatest source of fuel for mankind .Solar energy is the best way for solving the planet’s energy crises. A person can make its own photo voltaic cells called solar panels. The ones which a person can make in home cannot be as powerful as those which are made from silicon. But they work on the same principals.

1st Asia Solar Energy Forum held in Manila

High costs of investing and high risks are the main obstacles to fulfil the demand of solar energy. However, the current situation of power energy particularly in Asian region needs alternative sources, said president Asian Development Bank (ADB) Haruhiko Kuroda while speaking at First Asia Solar Energy Forum held in Manila.

President ADB said that Asia and Pacific region has the right combination of elements i.e. demand for energy, access to sunlight and arid land, technological maturity, and a sound investment climate.

“As a result, there is a risk of ‘Solar Divide’ where developing countries cannot receive the benefit of environmental technology despite its large potential,” Kuroda said. “The role of multilateral development institutions, such as ADB and its partners, should be to play a catalytic role to overcome these institutional capacity, policy, technology, and financing barriers.”

However, Kuroda said that obstacles such as high up-front capital costs of investing in solar energy and a high-risk perception have to date been keeping many solar energy investors on the sidelines. Many countries in Asia and the Pacific are well suited to solar power initiatives, and incentives and low-cost financing mechanisms should be made available to help the region make the transition possible, Haruhiko Kuroda said. The two-day forum, a part of the Asian Solar Energy Initiative (ASEI) announced by ADB earlier this year, brought together some 200 policy makers and solar energy-related professionals from 34 ADB member countries. The event was hosted by ADB in partnership with the International Energy Agency (IEA), the United Nations Industrial Development Organization (UNIDO), and the Renewable Energy and Energy Efficiency Partnership (REEEP).

Under ASEI, ADB targets to catalyse projects for about 3,000 megawatts in solar power by 2013. The ASEI also includes the establishment of a knowledge platform named the Asia Solar Energy Forum, support for project preparation, and direct financing of solar energy projects. It will also help raise concessional funds from donor countries to partly mitigate risks of the high up-front capital costs of investing in solar energy, and design other innovative ways to attract private-sector investment.

In her closing remarks at the Manila event on Tuesday, Vice-President for Knowledge Management and Sustainable Development Ursula Schaefer Preuss said the forum represented a step towards a solar energy revolution in the Asia and Pacific region. “Solar power has the potential to promote low-carbon growth, ensure energy security, increase access to energy for all and achieve ADB’s overall objective of poverty reduction,” she said. Schaefer-Preuss also announced that the second meeting of the forum would take place in Tokyo in December.

Solar Energy, Power, Electricity


Basic about Solar Energy, Solar Power and Solar Electricity.
In basic about solar energy, solar power and solar eletricity we will talk about the basic things behind this power. Formulas that will be used to find out which Solar Panel you should use and which battery you should select. And how much Solar Panels do you need to power up lights and other applications. Here are the main things you need to know and that will be used to calculate your needs. AC-DC system, Volt, Current(Ampere), Power(Watt), Resistance, Series and Parallel connecting.

AC-DC system
Ac stands for Alternative Current. Alternative current is almost that we found in wall outlet or electric outlet. Clever say'd that we found in wall. It is 230 Volt. DC stands for Direct Current. In solar panels it is used 12 volt dc system. DC is that current we can found in cells, batteries, and using adapters or regulators. See the picture of a dell charger. Dell charger also converts AC Current to DC 5.4 Volt and 2410mA. Solar Panels also uses DC voltage and Current.
