Contact Us Importance of solar energy Solar energy is considered to be the best option for the people and modern industries as it belongs to the renewable category.
Uses of Solar Energy The use of solar energy for space heating of buildings: The architecturial design of the buildings helps in their passive space heating using solar Energy.
Following strategies are useful for passive space heating: Provision should be there for an insulating screen cover for cooling requirement in summer.
Note that no mechanical equipment is needed for passive Solar panel essay heating. An active technology of solar space heating needs a collector to absorb and collect solar radiation.
Subsequently fans or pumps are used to circulate the needed air or heat absorbing fluid generally water. Water systems are more common than air systems as they offer better heat exchanger performance. The use of solar energy for the generation of electricity-photovoltaics: Photovoltaics PVs are arrays of cells containing a solar photovoltaic material that converts solar radiation into direct current electricity.
Multiple modules can be wired together to form an array. In general, the larger the area of a module or array, the more electricity that will be produced When the n-type and p-type semiconductors are sandwiched together, and irradiated with sunlight, the excess electrons in the n-type material flow to the -type, and the holes thereby Vacated during this process flow to the n-type through this hole and electron flow, the two semiconductors act as a cell, creating an electric field at the surface where they meet known as p-n junction.
It is this field that causes the electrons to jump from the semiconductor out toward the surface and make them available for the electrical circuit Advantages of solar Photovoltaics i Easy installation and maintenance ii Pollution free iv Viable for remote and isolated areas, forest, hilly, desert regions.
Disadvantages of solar Photovoltaics: The high initial cost especially of the silicon wafer is the major constraint in the widespread use of solar cells.
Applications of photovoltaic cells and solar panels: Photovoltaic cells are used in watches, pocket calculators, toys. Solar panels are useful to light up a house, run an irrigation pump, operate traffic lights, etc. Solar water heater consists of a flat-plate collector, with a black bottom, a glass top, and water tubes in between.
The black bottom of the collector gets hot by absorbing solar radiation. The heat warms up the water in the tubes. The insulated storage tank is placed above the collector, the cool water moves down into the tubes and the water moves into the tank by natural convection.
As the energy is coming from the sun, utility bills are much lower and within few years the installation cost is recovered.Science Research Project (Solar Energy) - According to my research about solar energy I recommend that FPL develop more solar energy production facilities and assist individual homeowners in applying solar panels to their homes.
They can be the most important components of your application—the essays. It’s a chance to add depth to something that is important to you and tell the admissions . Why the future doesn’t need us. Our most powerful 21st-century technologies – robotics, genetic engineering, and nanotech – are threatening to make humans an endangered species.

To recap — using an optimal Fourier Transform, David Evans discovered a form of notch filter operating between changes in sunlight and temperatures on Earth. This means there must be a delay — probably around 11 years.
This not only fitted with the length of the solar dynamo cycle, but also with. Solar power remains, after hydro and wind, the third most important renewable energy source in terms of globally installed capacity.
In , more than GW of solar photovoltaic (PV) power was installed in the world — an amount capable of producing at least TWh of electricity every year.
