SOLAR CELLS

What are solar cells/ solar energy?
Solar energy is the cleanest and most abundant renewable energy source available, and the U.S. has some of the richest solar resources in the world.

FACTS ABOUT SOLAR ENERGY

• A home solar panel system consists of several solar panels, an inverter, a battery, a charge regulator, wiring, and support materials. Sunlight is absorbed by the solar panels and is converted to electricity by the installed system. The battery stores electricity that can be used at a later time, like cloudy days or during the evening.

MORE FACTS

• Solar energy produces no pollution, no environmental effects and is Eco friendly
• The earth receives about 1,366 watts of direct solar radiation per square meter.

With new advancements today, scientific researchers discovered that solar energy could be more affordable in the future with decreasing cost and increasing efficiency.

The common domestic use of solar energy is from solar panels which absorb energy to use for cooking and heating water.

Solar energy could prove to be the major source renewable energy because of its massive potential and long-term advantages

Solar energy which comprises of radiant heat and light from the sun can be harnessed with some modern technology like photo-voltaic, solar heating, artificial photosynthesis, solar architecture and solar thermal electricity.

The solar technology can be distinguished into active and passive. Photovoltaic panels and solar thermal collectors which harness solar energy are examples of active solar technology. Passive technology includes constructing rooms to improve air circulation, orienting space to favorably use sunlight.

Solar power is the most exciting use of solar energy. It is how solar energy is converted into electricity by using either photo-voltaic (direct method) or concentrated solar power (Indirect). Large beams of sunlight are focused into a small beam using mirrors or lenses in the case of concentrated solar power. Photoelectric effect is used by Photo voltaic to convert solar energy into electric energy.
