mastery on the assignment in Module 1. Module 1 content was readings from the IRIS website. The content I read related to classroom behavior problems that an educator would encounter and strategies that could be used. After reading the IRIS module I was able to complete the assignment for module 1 with ease. The assignment questions were well written that I was able to complete with the material I had just read from IRIS module. 2. Reflect and discuss how the content in Module 2 prepared you to demonstrate mastery on the assignment in Module 2. Writing a reflection was the assignment for module 2. There were some articles to read for this assignment. However, the articles focused on one main point: classroom management. While I was reading…

others. For example, Module 2: Introduction to Flanders seemed to be shorter in length than any other of my other discussions up until that point. I struggled to find the words to analyze Giovanni Arnolfini and his Bride. My discussions before this one consisted of nearly 200 words and my discussion for this particular analyzation of this piece barley had 100 words. Another one of these discussions I struggled to make 100 words for was Module 2: From Flanders to Florence. I think Module 2 itself…

other irradiance, G, is I_l (G)=(G/G_0 ) I_l (G_0) 2 Voc Voc, the open circuit voltage, is the voltage measured with an open circuit. It is measured with the module in full sunlight using a voltmeter attached to the positive and negative leads of the module. On the I-V curve, this is the point where the curve crosses 0 amps. This is the maximum voltage that the module can produce on a sunny day…

First Solar, Inc. is a design and manufacturing company found in 1999 that produces photovoltaic modules, or solar panels, through the use of thin film semiconductors. The company however, has a much earlier history than scribed. In 1984, inventor and owner of Solar Cells, Inc Harold McMaster began manufacturing solar cells from silicon (energyandcapital, para 8). However, as silicon became more expensive, McMaster decided to switch to the use of a material called cadmium telluride. This…

individual PV cell is usually small, typically producing about 1 or 2 watts of power. To boost the power output of PV cells, they are connected together to form larger units called modules. Modules, in turn, can be connected to form even larger units called arrays, which can be interconnected to produce more power, and so on. In this way, PV systems can be built to meet almost any electric power need, small or large. Cells: Semiconductor device…

electricity with the use of photovoltaic cells/modules, also called solar cells/modules. One spaceship, called the ISS, uses decades old solar cells which convert 14% of the sun’s energy into electricity which shows its (the Sun’s light) strength, but the main question spaceship builders want to know is “Where is the edge of sunlight?”, aka where does the solar energy fall off so much that it is no longer useful to harness. Another path of research that researchers are exploring is the use of…

In 1839, a French physicist Edmund Becquerel proposed that few materials have the ability to produce electricity when exposed to sunlight. But Albert Einstein explained the photoelectric effect and the nature of light in 1905. Photoelectric effect state that when photons or sunlight strikes to a metal surface flow of electrons will take place. Later photoelectric effect became the basic principle for the technology of photovoltaic power generation. The first PV module was manufactured by Bell…

Advances in photovoltaic module technology, inverters, system installation practices, and design standards are improving the efficiency of solar systems and have led to the solar system becoming established as a strongly competitive energy source for off-grid energy applications. Substantially reduced Photovoltaic module cost and higher module efficiency compared are playing a key role in this expansion. The introduction of modern inverters that are more efficient, have higher…

Running a typical hot water heaters will cost over four hundred dollars a year. Solar hot water heaters consist of a solar module on a rooftop with the most sunlight (Springer). In that module are tubes that collect the solar energy of the sun to heat up the cold water. The now hot water travels to an insulated holding tank that can hold in heat and keep out the cold. Another solar hot water heater can have a booster that runs off of electricity that warms the water before traveling to the roof…

algorithm has improved tracking efficiency and better dynamic performance under varying solar irradiance and temperature. As the derivative of the power with respect to voltage dies out at MPP, hence the steady state oscillations would be vanished. The INC algorithm generally have fixed iteration step size. This step size can be determined by accuracy and tracking speed requirement. The INC MPPT with fixed step size has tradeoff between the dynamics and steady state oscillations. …
