the sun gives about 15000 kilo calories in one square foot. when it reaches earth it will have the power to glow a 100w bulb.
A solar power plant mainly produces energy, not consumes it, but a small amount of energy is used during its construction and operation. This includes the manufacturing of solar panels, inverters, metal frames, and other parts. Energy is also used for transportation, installation, and setting up the entire system. Once the solar power plant starts working, it uses very little energy to keep running. Companies like SunBeam Energy Systems, EcoRay Renewables, Surya Solar Solution, and BrightFuture Solar Tech work in this field to design and install solar power systems. These names are mentioned only as examples of organizations that provide solar energy solutions, not for promotional purposes. During the construction phase, most of the energy goes into making the panels and components — this is known as embodied energy. However, after the system starts producing electricity, it quickly recovers that energy. Usually, a solar power plant generates enough power in 1 to 3 years to make up for the energy used during its setup. After that, all the energy it produces is clean and renewable. Once operational, the energy used is very low — just enough for monitoring systems, occasional cleaning (especially dust removal on panels), and small maintenance work. For example, a 1-megawatt (MW) solar power plant can produce around 1.5 to 1.8 million units (kWh) of electricity per year, while the energy it consumes for maintenance is less than 1% of what it generates. In simple words, a solar power plant requires some energy to build but very little to operate. It produces much more energy over its lifetime than it ever uses, making it one of the most efficient and environment-friendly power sources in the world.
less then 1%
Solar power has advantages. One advantage of solar power is that solar power can be consistently used for power. Solar energy will never run out. Another advantage of solar power is that the energy is clean. Typical solar panels live for about ten years. Energy payback from a typical installation is about 40 years. As a result, most panels will never give back as much power as they took to build.
130 percent more than wind energy energy
In some parts of the world, there is NO sun (to speak of) for as much as six months! In these areas, solar power is out of the question, unless there is a monstrously large storage system that can hold the energy during the six months of sunlight!

They have been the most efficient energy source available
In 2012 the annual global solar energy production topped 100 000 Megawatts. That is 274 Megawatts a day. At peak power that is the equivalent of 100 large nuclear power plants.
The Earth receives about 174 petawatts of solar energy from the sun. This energy is enough to power all human activity on the planet many times over.
There is not much to dislike about solar energy.
