Solar Energy: How Solar Panels Work

Profit from your roof space: find local deals on solar in your area, eliminate your power bill, and join the solar revolution.

According to Shahan (2014) "in the state of Florida going solar cost around to $24,692 resulting

The greatest energy that can be produced by the sun is electricity. Photovoltaics, or solar cells, capture the sun and convert it into electricity. Solar cells were discovered by the Europeans back in the 1870’s when they used selenium to develop the telegraph. They found that when light hits selenium it would produce and electrical current. Soon enough there were many scientists and engineers working on photovoltaic systems. Silicon and Selenium proved to be the two best elements to conduct electricity when light hits them. Photovoltaic systems (PV cell) work by converting the suns light into electricity. A semi conducting material absorbs the sunlight, that energy knocks electrons loose from their atoms, this allows the electrons to flow through the material to produce electricity. The further development of solar cells can be attributed to the satellite industry. Solar cells were expensive and there was no use for them until satellites came. Because it is impractical to tether satellites it became important to develop solar energy at any cost that would power these satellites. This created a sustainable market for solar power, the first of its kind.

Currently solar power is beginning to expand horizontally throughout communities. This growth is creating a demand that is beginning to reduce the expense of purchasing and installing solar panels. The concept is catching on and the technology is improving as the demand increases.

Big idea: Solar energy is great for the environment because of no pollution, it gets a lot of energy, and it is a great investment. However, solar panels can come at a high cost to buy and to get installed.

A solar photovoltaic power system is a technology that converts the energy from sunlight into electrical energy. Residential solar photovoltaic systems can offset much of a household's power needs, depending on the size of the system and the household's needs. The output power from is directly proportional to power received from the sun, which varies throughout the day and year. The rated maximum output of the module might be achieved only occasionally, depending on actual site conditions. It is a renewable source of energy that is sustainable and totally inexhaustible. Solar energy is also a non-polluting source of energy that doesn’t emit any greenhouse gases when producing electricity.

The first step in installing solar panels is dependent on the size and location of an individual’s home. On average, the price can be anywhere between $15,000 and $40,000. Prices for solar panels have dropped significantly because of such high demand. The panels at this point are paying for themselves; a homeowner producing solar energy will save up to eighty-four dollars a month on electricity bills. Also, many houses with ‘green’ features tend to sell faster and for more money. If a person has decided that solar energy is bright in their future, and they have the green light from their utility company to install panels, the next step is to utilize efficiency in the home. A few

Solar panel absorbs sunrays as a source of energy to produce electricity. They usually comprise of smaller units known as photovoltaic cells (PV). They are the means of conversion. Electrical energy is converted into mechanical energy by means of a machine called electric motor.

Yes, solar panels are expensive but they will last for years. There are many more ways solar energy benefits the economy, directly and indirectly. By reducing your home’s use of traditional energy sources, you help keep natural ecosystems intact, reducing taxpayer funded cleanups and potentially devastating oil spills and natural gas leaks. If your photovoltaic solar panels generate more energy than your home uses, you can sell energy back to your local utility company, leaving more money in your pocket to spend at restaurants, movie theaters, or financial investments.

The sun is the source of all life on Earth. In just one hour the sunlight hitting the earth’s surface provides enough energy to power the global economy for a full year (Brown, 2015). The sun will continue to burn for billions of years, making it an unquestionably reliable source for renewable energy. Modern-day photovoltaic (PV) solar cells rely on the photoelectric effect, a phenomenon where light is used to free electrons from a solid surface - usually silicon - to create electricity. PV panels are typically installed on homes and buildings, or in ground arrangements, sometimes called solar farms.

Since solar agreements have a fixed electricity rate and utility rates increase over time, businesses who implement 24.1 MWdc (megawatts) solar panels can expect to save

In addition, solar energy operational costs are manageable. It is free from monthly charges compared to conventional sources of energy. Solar energy does not require raw materials such as oil and coal, and once the panels are built, there will be no monthly charges. In addition, the prices of fossil fuels are increasing day by day, and this means conventional energy will be very expensive. Solar energy will remain the most capable world’s future power supply because, it is cost effective once the plants are built, and there will be no transport costs like for conventional energy sources. Therefore, solar energy is cost-effective, and will help in future energy supply, as the maintenance cost is affordable, as long as they are installed properly, and are working efficiently ( Hans, 2012). Furthermore, with the improvement and advancement of technology, it will increase its efficiency, and cost of production thus, making it more cost effective and the world’s best

Have you ever been to a house or business that uses Solar? Solar power is a great way to save money as well as conserve energy. Solar panels convert sunlight into usable energy for housing, businesses, sections of properties, and even stuff like pool equipment. I want to discuss out the three important points about photovoltaic panels starting with the history of solar panels to understanding panels and how they are built, and finally the environmental aspects of photovoltaic panels.

The costs for installations are outrageous and it will take years just to make the installation fees back. If more of these expensive farms are built before we can research to get the price lowered, we will all be hurting through our tax dollars. So beware… solar technology isn’t as friendly as it seems!

“Solar panels are made up of multiple individual solar cells, which act as large semi-conductors and utilize large-area p-n junction diodes. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable
