As I have previously stated earlier in the evaluation PV systems, or Solar Home Systems (SHS), and many other solar power systems play a significant role in the harvesting of solar energy. But, the most used solar energy systems are Grid-connected systems, Stand-Alone Grid-tied Systems, Off-Grid systems, Stand-Alone Off-Grid Systems, and Stand-Alone Off-Grid Hybrid Systems. In grid-connected or grid-tied systems, solar energy is used during the day by the system owner. At night, the owner makes use of the previously harvested electricity grid. A huge bonus of having the grid-tied system is that the solar system does not need to be sized to meet peak loads, overages can be taken from the grid. In most cases, left over energy generated during the day can be sent back to the grid. Grid-connected systems must meet utility requirements. Most importantly, inverters must not emit noise that can interfere with equipment reception. Inverters must also switch off in cases of grid failure. Lastly, they must retain voltage quality and current output waveforms. Grid-connected systems can be applied to residential installations. Stand-alone grid-connected systems are the same as grid-connected systems, except with battery storage added to allow power to be generated even if the electricity grid fails. Stand-alone grid-tied systems can be applied to residential and business systems that require unlimited and uninterrupted power that’ll keep generating day and night. Off-grid systems are not connected to the electricity grid. The output of an off-grid system depends heavily upon the intensity of the rays being given off by sun. The more intense the sun exposure, the greater the output.They can also be used for water pumps and greenhouse vent...

...ms. Solar panels also can cause health problems because they are made of silicon which is hazardous when the dust from the silicon is inhaled, which forms scar tissue on your lungs. Lastly, cost and efficiency probably has the greatest negative effect of all. The cost of installations of solar units and solar panelling is very expensive and the energy can only be harvested during the day so the energy can quickly run out.
What is the potential future for solar energy?
Solar energy has already had great influence on the way we have viewed using energy sources.I believe in the future the human race will completely turn away from the use of oil and coal and focus a more efficient and cleaner way of obtaining energy, so we will only use solar energy. Solar energy will be the basis for all energy sources because the rays come from the sun so its accessible

First solar, Inc. is an American manufacturer of thin film photovoltaic (PV) modules, better known as solar panels. The company has an opportunity to expand into other regions, making the company more profitable. The company was founded in 1990, by Harold McMasters as Solar Cells, Inc., and it was then purchased by the True North Partners, LLC, who rebranded it as First Solar Inc. First Solar headquarters’ is located in Tempe, Arizona, U.S. The company went public in 2006, trading on the NASDAQ. First solar is ranked as the second largest maker of solar panels modules worldwide. They specialize in manufacturing photovoltaic modules, and also serve as providers of photovoltaic power plants. First solar became the first solar panel manufacturing company to “lower its manufacturing cost to $1 per watt and that has been done through their replacement of crystalline silicon for cadmium telluride as their semiconductor” to create panels (Lynley, 2011). The manufacturing company continues to grow and improve their products as well. We will be exporting our photovoltaic products to the Dominican Republic. The reason we chose to export solar panels to the Dominican Republic is simply because it is one of our smallest products yet the most accessible one.
Claim: Solar power has the potential to become the United States main supply of energy and replace are needs for more conventional and harmful forms of power generation.
The challenges that will be faced are the fact that many countries are already producing their own solar energy and storing it as well using it within the grid system that is already established. It’s called harnessing the energy. The main grid systems are aware of the energy that can be produced and in large countries are encouraging solar power for homes and businesses, solar energy is definitely the way of the future. In Burnaby for example if a home owner installs solar panels on their home and does not use all the power produced, the left over energy will go to BC Hydro the home owner will then receive a cheque for the extra energy Hydro is still hooked up to your home and monitors your consumption.
I believe the only way the United States and the world will see a large-scale transition to renewable energy sources is through education. Right now, it seems as though only a few pockets of people throughout the world are aware of the positive benefits of renewable energy sources. Not only is it better and cleaner for our environment, but the renewable energy industry could also provide a large-scale economic boost in the United States and other developed countries. I believe any negative economic effects that the transition from traditional to renewable energy may have on our economy would be counteracted by the plethora of positive effects that would come about as a result. According to ucusa.org, renewable energy already supports thousands of jobs in the United States alone.
Since the wind power and PV power can compensate each other to some extent during the day and night, the development of wind-PV hybrid power generation is attractive. As PV becomes more affordable, its demand will increase. With this increase, the future for grid tied PV systems will be better. PV systems can replace batteries, as its technology becomes more advance and standard for safety is increased. Grid tied PV systems are increasing in number over years.
The prime advantage of this approach to harnessing solar energy is that the process is simplified by combining energy gathering and storage into a single step. This process is robust, stable and cheap. One limitation of this process is, while this is useful for heating applications, production of electricity would require another step using thermoelectric devices or producing steam to run a generator.
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.
Our country is currently suffering energy-wise, we have been powering with inefficient sources for years now and the harm that it is doing to the country has started to become apparent. Renewable energy is the only way to stop, or at the very least set back the inevitable downfall of our ecosystem. I think that the next big breakthrough for renewable energy is implementing off-grid communities that use renewable sources as their main sources of power, so that we can potentially escape the energy rut that we got ourselves stuck in.
... 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 collectors are special type of heat exchangers that transform solar radiation energy into thermal energy. The key component of all solar system is the solar collector. This is a device which absorbs the solar radiation from sun converts into heat and transfers this heat to a fluid ( air, water, oil ) passes through the collector. The solar energy collected is carried from the circulating fluid either directly to the hot water or to a thermal energy storage tank from which can be utilized for use at night or cloudy days.
... Sunlight and heat will always be available to us because, it is a non-extinguishing resource and so, let us make use of it. With all these points made, there is no question that, solar energy is capable of becoming the world's future power supply. Works Cited Venables, M. (2008), “Bring me sunshine [Solar energy].” Engineering and Technology Vol.
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.
...is expressive solar equipment will be useless, however the use of solar battery chargers can help to reduce the effects of this disadvantage.
