What is solar energy? Solar energy is, simply, energy provided by the sun. This energy is in the form of solar radiation, which makes the production of solar electricity possible. Solar energy produces electricity when it is in demand – during the day particularly hot days when air-conditioners drive up electricity demand. In use, solar energy produces no emissions. One megawatt hour of solar electricity offsets about 0.75 to 1 tonne of CO2. Benefits of solar energy Solar energy is not only sustainable, it is renewable and this means that we will never run out of it. It is about as natural a source of power as it is possible to generate electricity. The creation of solar energy requires little maintenance. Once the solar panels have been installed and are working at maximum efficiency there is only a small amount of maintenance …show more content…
Solar Panels The solar panels are made up of photovoltaic (PV) cells, which convert sunlight into direct current (DC) electricity throughout the day. 2. Inverter This device converts the DC electricity generated by the solar panels into the alternating current (AC) electricity. 3. Electrical Panel The AC electricity is sent from the inverter to your electrical panel to power your lights and appliances with solar energy. The electrical panel is often called a "breaker box." 4. Utility Meter The utility meter measures your energy use. It actually goes backward when your system generates more power than you immediately need. This excess solar energy offsets the energy you use at night. 5. Utility Grid If we need that power from the utility company at night. The cost is offset by any excess solar energy you put into the grid during the day. 6. Power Guide Monitoring System Power Guide monitoring system continuously tracks your energy production and ensures that your solar power system is running smoothly. It will even alert our repair crews in the rare event that problems arise. How does a solar cell turn sunlight into
Despite generating electricity with fossil fuels for years and years there is a much better way that does not harm the environment. Using Solar panels does not produce any carbon dioxide unlike fossil fuels that “produces huge volumes of carbon dioxide, which is a gas that influences the global climate” (“Solar Power Vs. Fossil Fuels”). Having the choice to get power in a new way that saves the environment, home owners should not have to think twice about trying solar. In fact if home owners collect some amount of watts per hour on Monday, that will not reduce the amount of solar energy a home owner can collect on Wednesday or any other day that week. They can always keep collecting the power. No matter what people may argue about how much coal, natural gas and petroleum remains buried in the Earth, those fossil fuels will run out far earlier than the life of the sun ("Solar Power Vs. Fossil Fuels"). Home owners should invest in solar energy because solar systems have very dependable technology with little maintenance, they offer financial savings and they are better for the environment.
Solar energy is energy taken from the light that reaches earth's surface from the sun. There are four different kinds of solar energy, which are active solar systems, passive solar systems, photovoltaic cells and concentrating power systems. An active solar systems is a system that captures solar energy by mechanical means. Common active solar systems are often in buildings or homes. Some examples are roof collectors and water heating. Low Intensity and high variability have limited the use of active solar energy in Canada. A pass...
*an electrical device which converts an alternating current into a direct one by allowing a current to flow through it in one direction only.
The sun has been a major aspect of life since the beginning of time. People used many other forms of energy before electricity was discovered. There has been a debate over energy resources for years. Many people are worried about what current energy resources may be doing to the environment. Oil spills and nuclear power plant mishaps have only been a few accidents that have had a big impact on the environment and the people who inhabit it. There are plenty of energy sources that do not harm the environment and are still able to get the job done. Solar energy is one energy alternative that will insure the betterment of the country and, at the same time, protect the natural environment.

This is done by reflecting and amplifying the solar power to heat up the liquid generally water. As water has a very high boiling point at eats up a huge amount of thermal energy. That thermal energy is than used to rotate a turbine to generate electricity. Producing electricity by the mean of this technology will be cheaper and very eco-friendly. Although that technology is still under development theoretically this will have no carbon emission at all and will be safer than conventional technics that are being used. The figure below illustrates how it
Preview: Today I will discuss the potential that solar power has to become this country’s main supply of energy and the latest research that can make solar power more efficient and cost effective. I will also present the environmental benefits that come with using solar power over other and more harmful forms of energy.
Rectifiers convert an AC into a DC by allowing a current to flow through it in one direction only. There are two kinds of rectifiers,
The dc power input to the inverter is obtained from an existing power supply network or from a rotating alternator through a rectifier or a battery, fuel cell, photovoltaic array or magneto hydrodynamic generator. The filter capacitor across the input terminals of the inverter provides a constant dc link voltage. The inverter therefore is an adjustable-frequency voltage source. The configuration of ac to dc converter and dc to ac inverter is called a dc-link converter. Inverters can be broadly classified into two types, voltage source and current source
... and monthly water filling. Solar energy is the cleanest and purest form of energy, allowing for cleaner air overall in our environment. There is great hope for a lot more solar panels to be installed worldwide. Solar is a viable alternative energy with solar panels becoming more affordable and more efficiently designed.
Solar panels are systems that generated heat or electricity by using the energy to be carried ray of the sun. Solar energy panels absorbs the sun’s energy with the aid of dark surfaces located inside panels. After obtained heat, water is heated by transferring water by solar energy panel.
All useful generators of electricity come in two basic forms, alternating current and direct current. Direct current (dc) comes from generators that do not change in polarity, always producing a positive charge. In alternating current (ac) the polarity of the terminals is always changing from positive to negative. Thus you are left with alternating current flow. There are different ways of measuring and generating alternating and direct current.
Solar energy is clean energy that does not affect our environment. Solar power utilizes the sun’s energy to produce electricity, unlike other sources of energy, which rely on continual mining for raw materials. Consequently, producing solar energy from the heat from the sun does not result into the annihilation of the ecosystem, compared to the extraction of fossil fuels (Bode, 2005). Therefore, with the use of solar energy, it will help keep the environment clean, thus help to combat the issue of global warming, which is a threat to the world’s ecosystem worldwide. The use of solar energy will help save the worlds vegetation, and help prev...
The Earth captures around 342 W/m2 of energy from the sun. This energy is in the form of solar radiation, which the atmosphere reflects about 77 W/m2 and will absorb around 68 W/m2 of solar radiation annually. Therefore, the Earth’s surface is receiving, on average, about 197 W/m2 of solar radiation annually. This amount of energy received is roughly more than 10,000 times the amount of all energy humans consume per year. This energy can be used to produce electricity or heat. This energy source is not being used to it’s potential considering how much effort would come into effect to store and transport this energy.
When the sun heats the panel, it generates clean energy, which does not pollute the environment. All in all, the costs of solar power might not be applicable when it is certainly the best way to have a clean environment.
