Quasars were foremost identified as red shift sources. It was launched in and is one of the great observatories of NASA. Description: Hubble was created with a need to capture high-resolution images of universe.
It is capable of taking high-resolution images with negligible background light. History: Though the HST launched in , the idea of maki. Heliopause is the outer edge of the heliosphere which acts as the surface of the bubble that surrounds our solar system. The Heliopause is that part of the solar system which is exposed to particles and ions of deep space. Description: Heliopause is the boundary of the heliosphere which is the spherical region around the Sun.
It is filled with solar magnetic fields and solar wind that consists. Solar panels are those devices which are used to absorb the sun's rays and convert them into electricity or heat. Description: A solar panel is actually a collection of solar or photovoltaic cells, which can be used to generate electricity through photovoltaic effect.
These cells are arranged in a grid-like pattern on the surface of solar panels. Thus, it may also be described as a set of. An aurora is a natural phenomenon which is characterised by a display of a natural-coloured green, red, yellow or white light in the sky. It is predomi. ISRO was formed in with a vision to develop and harness space technology in national development, while pursuing planetary exploration and space science research. A Lagrangian point is a position or location in space where the combined gravitational forces of two large bodies is equal to the centrifugal force that is felt by a third body which is relatively smaller.
The two large bodies here may be the Earth and Sun or the Earth and Moon. Description: A lagrangian point is also known as a Lagrange point, Liberation point, or L-point. These points are loc.

For most people, the first solar panel in their life was probably embedded in their new calculator - circa the s! Today, solar panels and complete solar panel systems are used to power a wide variety of applications. Yes, solar panels in the form of solar cells are still being used in calculators. However, they are also being used to provide solar power to entire homes and commercial buildings, such as Google's headquarters in California. Solar panels collect clean renewable energy in the form of sunlight and convert that light into electricity which can then be used to provide power for electrical loads.
Solar panels are comprised of several individual solar cells which are themselves composed of layers of silicon, phosphorous which provides the negative charge , and boron which provides the positive charge. Solar panels absorb the photons and in doing so initiate an electric current. The resulting energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their atomic orbits and released into the electric field generated by the solar cells which then pull these free electrons into a directional current.
This entire process is known as the Photovoltaic Effect. An average home has more than enough roof area for the necessary number of solar panels to produce enough solar electricrity to supply all of its power needs excess electricity generated goes onto the main power grid, paying off in electricity use at night. In a well-balanced grid-connected configuration, a solar array generates power during the day that is then used in the home at night. Net metering programs allow solar generator owners to get paid if their system produces more power than what is needed in the home.
In off-grid solar applications, a battery bank , charge controller , and in most cases, an inverter are necessary components. The solar array sends direct current DC electricity through the charge controller to the battery bank. The power is then drawn from the battery bank to the inverter, which converts the DC current into alternating current AC that can be used for non-DC appliances.
Assisted by an inverter, solar panel arrays can be sized to meet the most demanding electrical load requirements.
The AC current can be used to power loads in homes or commercial buildings, recreational vehicles and boats, remote cabins, cottages, or homes, remote traffic controls, telecommunications equipment, oil and gas flow monitoring, RTU, SCADA, and much more. A solar panel , or solar module , is one component of a photovoltaic system. They are constructed out of a series of photovoltaic cells arranged into a panel. They come in a variety of rectangular shapes and are installed in combination to generate electricity.
These panels can be used to supplement a building's electricity or provide power at remote locations. In addition to residential and commercial use, there is large-scale industrial or utility use of solar. In this case, thousands or even millions of solar panels are arranged into a vast solar array , or solar farm , which provides electricity to large urban populations. The main component of any solar panel is a solar cell.
Specifically, a number of solar cells are used to build a single solar panel. These cells are the part of the device that convert the sunlight into electricity. Most solar panels are made from crystalline silicon type solar cells.
