    • Why all this Noise about Renewable Energy? Why all this Noise about Renewable Energy? The Earth receives 174 petawatts (PW) of incoming solar radiation (insolation) at the upper atmosphere. Approximately 30% is reflected back to space while the rest is absorbed by clouds, oceans and land masses. The spectrum of solar light at the Earths surface is mostly spread across the visible and near‐infrared ranges with a small part in the near‐ultraviolet. The total solar energy absorbed by Earths atmosphere, oceans and land masses is i approximately 3 850 000 exajoules (EJ) per year. I 2002 thi was more energy i t l 3,850,000 j l In 2002, this in one hour than the world used in one year Photosynthesis captures approximately 3,000 EJ per year in biomass. The amount of solar energy reaching the surface of the planet is so vast that in one year it is about twice as much as will ever be obtained from all of the Earths non‐ renewable resources of coal, oil, natural gas, and mined uranium combined. Solar energy can be harnessed in different levels around the world.

    • Sharing a little we know  Sharing a little we know Solar energy is a completely renewable resource This means that even when we resource. cannot make use of the sun’s power because of nighttime or cloudy and stormy days, we can always rely on the sun showing up the very next day as a constant and consistent power source. Oil, which is what most people currently use to power their homes, is not a renewable resource. This means that as soon as the oil is gone, it is gone forever and we will no l d ill longer h have power or energy. Solar cells make absolutely no noise at all. They do not make a single peep while extracting useful energy from the sun On the other hand the giant machines sun. hand, utilized for pumping oil are extremely noisy and therefore very impractical. Very little maintenance is required to keep solar cells running. There are no moving parts in a solar cell, which makes it impossible to really hurt them. Solar gp , p y cells tend to last a good long time with only an annual cleaning to worry about. Solar powered panels and products are typically extremely easy to install. Wires, cords and power sources are not needed at all, making this an easy prospect to employ. employCENTRE FOR APPLICATION OF RENEWABLE ENERGY        Phone : +918097119058     WEBSITE : HTTP://WWW.CARE‐INDIA.COM   EMAIL CARE@CARE‐INDIA.COM
    • Sharing a little we know   and a little more Sharing a little we know and a little more Solar energy is energy from the Sun This energy is then converted to provide Sun. heating, lighting and electricity for our homes and businesses. Photovoltaics, Photovoltaics or PV for short is a solar power technology that uses solar panels short, to convert light from the sun directly into electricity. This Endless Energy resource (the Sun) will remain more or less the way it is now for about another 5 billion years How it works; Photovoltaics, or PV is the direct conversion of solar energy into electricity. PV , gy y systems do not have any moving parts, are modular and come in a wide range of power capabilities. PV panels are energiized when exposed to sunlight and produce an electrical (DC) current. The energy generated can be used immediately or stored in batteries for later use. Normally the excess energy generated in the PV system during sunny periods can either be sold back to your wire service provider or is stored in batteries to provide electricity at night or when there is not enough sun. = ElectricityCENTRE FOR APPLICATION OF RENEWABLE ENERGY        Phone : +918097119058     WEBSITE : HTTP://WWW.CARE‐INDIA.COM   EMAIL CARE@CARE‐INDIA.COM
