Solar Power

Plants capture solar energy through photosynthesis and use it to produce simple carbohydrates it uses to grow. Farm animals consume plants, and metabolize the carbohydrates created by the plant and grow themselves. For this reason, solar energy powers the food chain.

On average, the solar energy radiated by the sun on 1 square meter of the Earth's surface in Canada is about 1000 watt-hours per square meter per day. This value varies depending on several factors such as location, season, and weather conditions.

I don't think anyone knows yet, the more modern ones you buy now have not been around long enough. I think most people assume about 25 years, but time will tell. You probably need that sort of period to achieve payback on the installation cost.

If it replaces power that would otherwise produce carbon dioxide, then it must do so, because it does not emit CO2. This is not taking account of the process of manufacture of the solar panels-this may cause some pollution.

Addition:

The CO2 cost of manufacturing solar panels is cancelled out in just a few years of using the solar panels for energy, whether they are photovoltaic panels for electricity, or solar thermal panels for heating hot water.

Solar energy is being used in Philadelphia, Pennsylvania mainly for residential, commercial, and municipal buildings. There are numerous solar photovoltaic installations on rooftops and at ground level throughout the city, helping to offset energy consumption and reduce carbon emissions. Some notable solar projects in Philadelphia include the Philadelphia Navy Yard and Lincoln Financial Field, home of the Philadelphia Eagles.

This can be estimated from the size of the earth and its distance from the sun, and the result is that the sun emits about 2 billion (2 x 109) times as much energy as hits the earth. So as a percentage what the earth receives is pretty small, 5 x 10-8 percent if my arithmetic is right

Solar energy is being used the most in countries with high levels of sunlight and a commitment to renewable energy, such as China, the United States, India, and countries in Europe. These regions have large-scale solar energy installations on rooftops, in solar parks, and integrated into their energy grids.

Solar energy has been used for heating and cooking purposes since ancient times. The first photovoltaic cell, which directly converts sunlight into electricity, was invented in 1954 by Bell Laboratories.

By measuring the output. Each solar panel has a wattage, for example, 200 watts. You can multiply that wattage by the number of hours in a day that the sun shines, for example, 6 hours, and the answer is in kWh (0.2 kW x 6 = 1.2 kWh).

Solar power is formed through the process of converting sunlight into electricity using solar panels. Solar panels contain photovoltaic cells that absorb sunlight and convert it into direct current (DC) electricity. This electricity can then be converted into alternating current (AC) electricity and used to power homes and businesses.

For 'solar power', solar panels that produce electricity you need daylight (the sun needn't be direct). There isn't really a second condition although many factors improve how much electricity is produced by the panels:

Orientation:

Better performance will come from mounting the solar panels to face the sun, and at any angle to the ground. The best angle depends on where you are on the earth. Also, the array of panels should also face the same direction For example, half the system facing south east, and half the same system facing north will degrade the performance of the whole system.

Shading:

No shading at all accross the whole system will improve performance. To put it another way, if you were to shade a quarter of an array of Photovoltaic panels, then you will degrade the performance of the whole system. No shading at all is best.

System sizing:

If the system is to provide AC power to a house, then the number of panels need to be well matched to the inverter or inverters. The better the match the higher the effieciency of the whole system.

Advantages: *Sun is the ultimate source of power or energy. *Without sun, no life can exist on the planet earth as the autotrophs would be unable to synthesize food. So the heterotrophs, also would'nt survive. *The sun's gravity controls the planets' rotation,revolution and precession. *Plays an imp. role in maintaining climatic order in Earth.(winds,rainfall,temperature,humidity etc.) DISADVANTAGES: *It emits harmful UV rays. As the earth's ozone layer is depleting due to the accumulation of CFCs, these harmful rays penetrate the Earth's atmosphere and seriously affect our skin causing "skin cancer"! *Excessive amount of heat weakens our body which can function beneficially only at an optimum temperature.

A solar farm will typically have thousands or even hundreds of thousands of solar panels. A great place for a solar farm is out in a barren area that isn't productive for anything else, but has an abundance of sunlight.

Solar panels were invented in 1954 by researchers at Bell Labs. They developed the first practical silicon solar cell capable of converting sunlight into electricity.

Solar power plants are needed to generate electricity using renewable energy from the sun. They help reduce greenhouse gas emissions, combat climate change, and decrease dependence on fossil fuels. Solar power plants also provide a sustainable and clean source of energy for both residential and commercial use.

Solar energy is energy powered by radiant light and heat from the sun. It was created by Frank Shuman, a U.S. inventor, in 1897.

Aubrey Eneas is known for his work as a jazz guitarist and composer. He played with various jazz bands and orchestras in the mid-20th century, contributing to the vibrant jazz scene of that era. Eneas is recognized for his skill on the guitar and his contributions to the development of jazz music.

At present solar energy is expensive to install and generally has to be subsidised, by government or by consumers. It is subject to weather conditions and obviously does not produce power at night.

Mirrors, water, shiny metal... pretty much anything shiny. Antarctica reflects a large quantatie of the suns rays but i dont know how much.

Solar energy is not something that was made by a single person. It is a form of renewable energy that comes from the sun and has been harnessed for centuries by various civilizations for activities like heating and lighting. In modern times, scientists and engineers have developed technologies like solar panels to convert sunlight into electricity on a larger scale.

Yes, solar panels are commonly used in satellites to convert sunlight into electricity to power the satellite's systems and instruments. They are typically mounted on the satellite's exterior to receive maximum sunlight exposure. Solar panels are a reliable and efficient way to generate power in space where other energy sources may not be readily available.

As of 2021, there are over 700,000 solar power plants in the world. The number is continually increasing as more countries invest in renewable energy sources like solar power.

Silicon panels produce STC in production which can be fully recycled creating a closed-loop system. Therefore it produces no bad by-product.

Cadmium Indium Gallium Selenide or CIGS had some concerned that harmful chemicals would be released if the panels were caught in a fire but extensive fire testing found they burning of the cells actually encapsulated the harmful material within the other materials in the array releasing less than even slightly harmful amounts of the material. In addition, such manufacturers as First Solar have created escrow accounts for a forced recycling program meaning all the panels when no longer working will be picked up by the company and recycled. Reusing 90+% of the panels material and removing any harmful possibilities.

Solar array's of course need no fuel and produce no waste simply converting the sun's energy directly into DC energy.

Traditional silicon solar panels when they are recycled either because they are being replaced or have become damaged can be almost fully recycled as well as the valuable materials which are basically silicon, aluminum, steel, copper, and glass all of which can be recycled.

The other harmful chemicals present of course are lead, cadmium, selenium, tetrachloride, and indium. However, between modern sealed landfills, the trace amount of these materials and the economic incentive from recovering the materials in panels these are not a significant or even minor threat to the environment.
