Natural resources of fuel are at a risk of being eliminated due to their consumption in very large amount. Scientist are trying to find new ways of producing fuel. One of them is the solar energy. Solar systems have been invented which convert heat energy into electricity. These solar systems are now in use and are cheap source of electricity. To understand the whole working of the solar energy systems, one must understand about the basic thing that is “Solar cell”.
Use Of Silicon In Solar Cells
The world has progressed rapidly in the field of solar energy. It is easy to use and is cheapest form of energy. To understand about solar energy system, one must start from basic level.,, a solar cell. The basic component of the solar cell is the semiconductor used to convert heat energy into electric charge. Many elements are now being used for this purpose but the best element that has been used from a long time and is still a part of many solar devices is Silicon. The guide line for solar cells is provided by the silicon structure in a photovoltaic (PV) cell. The current is produced in these cells by movement of the electrons from their respective shells. To move more electrons, additional impurities are added in silicon.
Producing Electricity From Solar Cell
A solar grade is made up with a crystalline structure. Semiconductor used in the cells is Silicon atom having three layers holding electrons. The no. of electrons increase in the center of atom. When the electrons from the outer shell of silicon escape, electrons from inner shells move to replace them. This moving results in creating a locked structure. Due to this reason, most of the silicon solar cells ape P-type or N-type silicon cells. N-type cells are added with the impurity that is mainly phosphorous which helps more electrons to escape from the outermost cell of silicon atom. Read the full story

Solar inverter is a great tool that utilizes sunlight and converts it into reusable electricity. It is an integral part of a solar generator. Solar inverter can be bought separately or along with the solar panel and battery for setting up a fully functional solar power system. If you are considering buying an inverter separately then make sure you are going to buy an inverter that matches with the wattage output of the solar panel that is installed in your home.
Working of Solar Inverter
Solar inverter works on a very simple principal that is receiving sunlight by the solar panels and conversion of that sunlight by the help of solar inverter into reusable electrical power.
Standalone Inverter
The power that is generated by the solar inverter is stored in batteries. This is the point where inverters are needed. Solar inverter converts the direct current (DC) that is stored in the battery. That DC is converted into the alternating current (AC) that is then used for domestic purpose for powering electrical equipment and devices. The inverter that performs this simple task is referred to as the standalone model.
Synchronous Inverter
In this type of inverter energy from the photovoltaic (PV) module or a solar panel is directly connected to the utility grid, in such a case a grid-tie inverter or a synchronous is required for that energy. The synchronous inverter performs the same function as the standalone inverter does. It converts the direct current (DC) into an alternating current (AC). Read the full story

Solar air conditioning or refrigeration is considered to be a viable option of indoor cooling in the near future. Solar air conditioning has two main types that are active and passive. These two types in turn have further subtypes. One of these types is solar compressor cooling. Solar compressor coolers are not different from traditional air conditioning or refrigeration systems in their working. But there is a basic difference and only difference and that is the utilization of solar energy.
Working of Solar Compressor Cooling
Sun power energy is used to empower the electrical compressor. In the electrical compressor air is compressed and then it is heated further before it is passed through a condenser. In the condenser that air is absorbed and then this air is cooled.
Solar Compressor in Hotter Climates
The compressor during summer season or hotter climatic conditions can be transferred altogether through feeding the air (that has been heated) directly to the condenser.
Solar Absorption Cooler
Absorption chillers that are also known as solar absorption coolers can reduce the amount of energy that is being consumed by the cooling system to a great extent. In this way these compressors become more cost effective.
Types of Absorption Chillers
There are various types of absorption chillers. These types include single absorption chiller, double absorption chillers and triple absorption chillers. Read the full story

To gain electricity through solar power is getting very popular now a days. Its use has become very common in this century. In face solar energy system is very easy to use and its benefits are numerous. It is a cheap way to get electricity. Following are some important aspects of solar power system:
Photovoltaic Panels
When we talk about a complete solar energy system, the first and foremost thing that comes into mind is photovoltaic panel. A home solar energy system is comprised of these important panels. And off course in order to get a reliably amount of solar energy one must have high quality photovoltaic panels. If these panels are solid and of good quality then sufficient amount of energy can easily be collected. Moreover they must have rightly placed in order to absorb power from the Sun. So while buying panels’ extreme care must be taken otherwise it would be the wastage of money.
Semiconductors
When you have completed the installation of solar panels then they started to absorb heat from the sun through its rays. One of most important parts of these panels is semiconductor. One common example of semiconductor is silicon. Electric current is created when the photons of sun rays hit the electrons.
Current Produce
When electrons are turned loose then a direct current is created. But most of home appliances like freezers, microwave ovens, DVD players, dishwashers and television are run through alternative current. So in this case it would not be possible to run the most important things of daily use. Then a question comes into mind that if panels produce direct current then it is useless to have a home solar energy system.
Converter
This problem can be solved with the help of a converter. It is also an important part of solar power system. Read the full story

Solar Refrigeration by Photovoltaic Cells
Photovoltaic or solar cells are used to produce refrigeration. These solar cells utilize the solar power energy and convert it into electrical power. Solar refrigerators also contain thicker insulation hat is typically about 4 inches. Initial expense of buying a solar refrigerator is higher than the conventional refrigerator or electrical refrigerator.
Features of Solar Refrigerators
These refrigerators are small in size, jus about the chest size. Despite of high initial costs, they are still cost-effective than electrical refrigerators. These refrigerators are portable and can be used anywhere, but most often they are used by cabin owners, remote home and RV owners. These refrigerators typically run on the backup battery of 12-volt and are capable of reaching temperatures of about 30 degrees cooler than the exterior temperature. These refrigerators do not require high amp-hour because solar panels are the primary source of battery recharging for these refrigerators.
Output of Solar Refrigerators
Models of solar refrigerators are typically marketed on the basis of their output in watts. Watts can be converted into amps by using basic equation that 100 watts provide approximately 6.25 amps or 16 volts when the sun is shining at its peak. It doesn’t account for solar intensity hat changes throughout the day. Read the full story
