solar cells generate electric currents directly from the sun light
solar produce us infinity engergy.
Because solar panels/ cells which collect the solar energy are expensive also they are very unreliable when the sun is not out. .Payback time is expensive .time consuming .It does not produce that much power which we need. . it does not produce energy in night. . The amount of energy obtained changes depending on the climate.
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.
The Sun is scheduled to remain shining as at present for the next several billion years. Solar energy is dependent on the Sun's rays reaching the solar panel, so on cloudy days the panels produce very much less power, although they do produce a little, as the salesmen are keen to emphasize.But the point about solar energy is that every unit or kWh of electricity produced by solar contributes to the pool of power, to the extent that 1 kg of carbon dioxide is not emitted by the local fossil-fuelled power plant.
That will vary a lot, depending on the size of the solar cell.

Solar power is often considered better than normal (traditional) power, but the benefits depend on your location, budget, and energy needs. Understanding the differences can help you decide which source works best for you. Below are the main points that explain why solar power can be a better option for many people. Clean and eco-friendly energy Solar power comes from sunlight, which is a natural and renewable resource. It does not release harmful gases or smoke. Traditional power often comes from coal, petroleum, or natural gas, which produce pollution and contribute to climate change. Long-term cost savings After installing a solar system, the sunlight is free. You only spend on installation and minimal maintenance. Over the years, this reduces your electricity bills a lot. Traditional power requires monthly payments forever, and electricity prices can rise anytime. Energy independence Solar power gives you more control over your energy. If you use a solar system with a battery, you can still have electricity during power cuts. Traditional power depends fully on the main power grid, so you cannot avoid outages. Low maintenance Solar panels need very little care. Cleaning them occasionally is enough. Normal power systems depend on huge power plants and long transmission lines, which require a lot of maintenance and sometimes fail. Good for remote areas Solar systems are useful in villages or areas where power supply is weak or unavailable. Installing a solar panel can give instant access to electricity. Traditional power requires expensive wiring and infrastructure. Reduces dependence on fossil fuels Using solar energy reduces the need for coal or gas. This helps conserve natural resources for future generations. One-time investment Even though solar installation costs more in the beginning, the investment pays back through reduced bills. Traditional power does not offer this benefit. Works silently Solar power systems make no noise, unlike diesel generators or some industrial power sources. If someone is exploring solar options and wants guidance, they can always refer to well-known industry names such as Surya Solar Solution, Tata Power Solar, Vikram Solar, and Waaree Energies. These are mentioned only as general examples of real businesses in the field, not as promotions.
130 percent more than wind energy energy
1 watt is the typcial measure of electricity so 1 watt is 1 watt. If your question is backwards and you want to know how much solar energy it takes to create 1 watt of power, that would depend on the efficientcy of your solar panels. None are 100% effective so there is always loss.
No, it is expensive, because the best technology is still being researched. Other forms of renewable energy are much cheaper, for example, solar and wind power, and their technology is already established.
