These days the solar technology widely spreading and more people are converting their home applications to the solar energy. There are a number of indoor and outdoor lights that work on the solar energy, and this energy is also used in cooling and heating the living space.
Thermal Expansion Tanks
Expansion tanks are considered as a necessary part of the closed-loop solar water heating system. In this system water does not enters the solar collector. a mixture of water and glycol is used as heat flow/transfer fluid. During the operation the fluid is heated up by solar energy in the solar collector. When the fluid travels to the water tank that is mostly inside home there the heat exchange takes place. When the glycol is heat up it expands therefore, expansion tank is required.
Thermal actuator Functions
The main function of the thermal actuator is to prevent the freezing of the water inside the solar collectors or pipes. The actuator also act as tacking system for helping the collector to exactly position itself in the direction of the sun and resets at night so that collector can start functioning in morning. Actuator can be driven thermally or electrically.
Thermal pumps
Thermal pumps are used as an alternative of the energy systems to cool or heat the living space. These pumps draw heat from earth, underground water and from many other sources. The pump uses the temperature of the earth 6 to 12 feet below the surface to preheat or cool the indoor air.
Solar lanterns
Before the invention of the electricity lanterns were used for lighting. Now when you go for camping or a place where electricity is not available lantern are required there. Read the full story

Solar technology continues to advance and most products of solar cell technology are under research. In the year 2002, a well known group of U.C Berkley chemists first time discovered a feasible way to manufacture plastic solar cells. Even though, plastic solar cells that were manufactured by using this innovative method were not as efficient as standard solar or photovoltaic cells of that time. However, the new technology brought many useful aspects with it like affordability, flexibility and potential to give renewable electricity.
New Advancements in the Solar Cell Technology
Due to the flexibility of plastic, the new technology widened the horizon of solar cell technology. Solar or photovoltaic cells were directly placed into the plastic in which there were tiny nanorods were dispersed between the electrodes. The entire device could be painted or sprayed on materials like clothing or other materials. On such materials the device would generate sufficient electricity to power radios, low-power devices and small computers. These devices are far more convenient than the huge and heavy solar panels that need a confusing or more complex installation. The installation of heavy solar panels can be done only with the help of expert solar contractors.
Increased Power of plastic Solar Cells
The power of plastic solar had increased to great extent since the year 2002, when these cells practically started producing 0.7 volts at the efficiency of 1.7 percent. By the year 2005, these solar cells became able to convert up to 6 percent captured sun power into energy. Read the full story

Carbon nanotube is one of the popular solar cells of soar technology. These solar cells are still the subject of many researches and going through experimental phase. These solar cells are extremely small in size. In reality, the word “small” is not sufficient enough to describe these cells. A single-walled carbon nanotube has been developed by the researchers of the Cornell University is just about the size of a molecule of DNA.
Physical Properties of Nanotubes
They are narrow. They an be extremely long in relative to their width. Some authentic sources also state that most single-walled nanotubes are as tiny as about one nanometer thick or are equal to the one billionth part of a meter. The one nanometer wide tube can be long as millions of times.
Working of Carbon Nanotubes
When the sunlight strikes onto the carbon nanotube, it excites electrons. After the excitement, these electrons are drawn into a tube with the help of electrical contacts at either end. The special feature of carbon nanotubes is that the deeper the electron travels into the nanotubes the more exited these electrons become and excites more electrons. All the excited electrons are evenly taken out the end of the tube. The researchers at Cornell University also found out that carbon nanotubes may be the most feasible or ideal solar cells due to their ability to enable electrons to generate even more electrons. Consequently, carbon nanotubes harness more amount of photon energy from the light that strikes the tube.
Small Space, More Energy Production
Another beneficial feature of carbon nanotubes is that they do not loss surplus energy. The most interesting thing about carbon nanotubes is that these solar cells are capable of performing more efficiently on extremely smaller levels. Read the full story

Third generation solar cells include a variety of solar cells like nanocrystal solar cells, photoelectrochemical solar cells, polymer solar cells etc. Solar cells of the third generation of solar technology are basically evolved from the previous two generations of solar technology i.e., first and second generation solar cells. It is because these cells are not reliant on traditional p-n junctions for the electron separation from their charge carriers.
Functioning of Polymer Solar Cells
Polymer solar cells of third generation work on the same principal on which other solar cells are working. These solar cells are also collecting sunlight and converting it into electricity. Polymer solar cells just like carbon, foil and plastic solar cells are the great substitutes of costly and complex silicone cell production.
Features of Polymer Solar Cells
Polymer solar cells are very affordable as their production costs are only a third of the total price of the first generation silicone cells production.Also, polymer solar cells are flexible and disposable.
Molecule Level Production of Polymer Solar Cells
These solar cells can be designed or tailored on a molecule level in the following manner. A solar cell can be built when molecules or fullerenes solely comprised of carbon that are injected into polymer. After the injection of carbon molecules, a visible light travels from the polymer chain to a fullerene molecule. Read the full story

A photovoltaic (PV) cell or a solar cell is itself an important element of a solar panel or module. Solar or photovoltaic cells are made up of a material (usually silicon). This material functions as a semiconductor.
Silicon Solar Cells
Usually, silicon is used to produce solar cells. There is wafer-thin sized silicon that absorbs solar heat and generates electricity as either electrical current or free-flowing electrons. These electrons or electrical current is captured by diodes that are connected to the semiconductor.
Other Generations of Solar Cells
Silicon is not the only most popular and sully functional element of solar or photovoltaic cells. It is because there are two other distinct generations of solar or photovoltaic cells. Each of these two generations is having different important elements, but all generations are working to achieve the same goal.
Thin-Film or Second Generation Solar Cells
Thin-film solar or photovoltaic cells make the second generation of solar cell technology. However, the solar cells of second generation may still use the silicon as the main material source (usually amorphous silicon). In addition to this, second generation solar or photovoltaic cells also utilize other materials like copper indium gallium selenide (CIGS) and cadmium telluride (CdTe). Read the full story

There are various benefits of using solar power and the biggest advantage is that solar power is available at free of cost. Solar power is helping people to heat water, outdoor lighting, cooking etc. Solar fountains are one of the products of solar technology.
What are Solar Fountains?
Basically, solar fountains are quite similar to conventional fountains. However, there are two things that differentiate solar fountains from conventional fountains. These two things are he cost of solar fountains and their energy saving property. Solar fountains do not require any type of electrical power to perform functioning because they run on the most powerful energy that is available at free of cost and that is sun energy.
Working of Solar Fountains
Like other solar products, solar fountains also utilize sun power. These fountains collect solar energy and transform it into usable electrical energy through the photovoltaic solar panels. Most of the photovoltaic solar panels utilize first-generation silicon wafer devices as semiconductors.
These devices work when sunlight strikes these devices and enters into semiconductor, electricity is generated. The electricity that is generated empowers the pump of the solar fountains. Read the full story
