Solar Energy is the fastest growing renewable energy and power supply source. The sun in our solar system has been producing energy for billions of years. The rays of the sun or solar radiation that reaches the earth is called solar energy.

Solar PowerSolar Energy - Converting sunlight into electricity is called solar power. This conversion of sunlight into electricity can be done by using Photovoltaic (PV)
, or with concentrating solar power (CSP).

Solar Photovoltaic Cells - Photovoltaic (PV) are an array PV solar cell. These PV cells are made up of solar photovoltaic material that converts solar radiation into direct current (DC) electricity.

Materials used for photovoltaic include monocrystalline silicon, polycrystalline silicon, microcrystalline silicon, cadmium telluride, and copper indium selenide /sulfide.

Solar Photovoltaic Panels - Solar panels (SP) / Solar Modules or photovoltaic (PV) panels are made from electrically connected array or solar cells or PV Cells.

Solar Electricity: Solar electricity can be produced in two ways:

  1. Using Photovoltaic (PV devices) or solar cells

  2. Concentrating Solar Power Plants

Solar Battery: Solar batteries are used to store solar energy (solar electricity). Solar Battery discharge power as and when needed. Rechargeable solar batteries are used in off-grid PV systems to store excess electricity. Some solar battery banks use wet cells, while others use sealed or gel cell batteries. NiMH batteries are preferred and most common when it comes to solar energy because they are better than standard NiCAD batteries in terms of charging and release cycles.

Solar Lights: Solar lights are in fact a very cost-effective way for both indoor and outdoor lighting requirements. LED bulbs are used in most solar lights because consume less electricity and produce more bright light. Indoor and outdoor solar lighting has gained popularity over recent years. Use of solar lights can not only save the environment but it can also save money on your electricity bills and spread awareness about solar energy and solar lights.

Home Solar Panels: The best way to use solar energy at home is to install energy efficient roofs - Solar Panel Roofs and Solar Roof Shingles. Many people think that installation of home solar panels is too complicated. This is not the case. There are many companies that can help you to find the right set up for all your energy needs. These companies can also do the installation for you.

 

Solar Products: Some of the most common products using solar energy are - solar water heaters, solar coolers, solar cookers, solar pool heaters, solar fountains, solar birdbaths, solar garden accents, and outdoor solar lights. Other less common solar products include - solar clothing, solar toys, solar ovens, solar laptop battery chargers etc.

Solar Energy Companies: Some of the best and most prominent solar energy companies in the world in terms of market popularity are: First Solar (FSLR), SunPower Corporation (STP), Suntech Power Holding Ltd. (LTP), JA Solar (JASO), Solar Enertech Corp (SOEN)


Solar Energy
is the fastest growing renewable energy and power supply source.

The sun in our solar system has been producing energy for billions of years. The rays of the sun or solar radiation that reaches the earth is called solar energy.

This energy of the sun or solar energy can be converted into other forms of energy, such as heat energy and electrical energy or electricity (solar electricity).

Even though, renewable solar energy has existed ever since the existence of our solar system, its potential was not recognized until 1830 when a British astronomer, John Herschel, used a solar thermal collector box to cook food during an expedition to Africa. This thermal collector device absorbed sunlight to collect heat and cook the food.

This technology to use energy from the sun is now advanced and is used to several purposes such as
solar water heater, solar light, solar cooker and several other purposes where electricity is needed.

Advantages of Solar Energy

There are numerous advantages of using solar energy. The first and foremost advantage is that solar energy is completely free and green and renewable. It is also termed as green energy. Solar electricity is efficient and can save money for you in the form of huge electricity bills. It also helps to preserve our environment. Solar energy is undoubtly the energy and power source of the future.

Drawbacks of solar energy

The very first disadvantage of solar energy is it is not constant. The amount of sunlight reaching the earth depends on several factors such as location, time of day, time of year, and weather conditions.

Second drawback of solar energy is that solar energy is spread over a large surface on earth. Therefore, a large surface area is needed to collect the energy for any useful purpose.
