Example Of Solar Energy Forecasting

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.

The PV module has been designed by considering the irradiance, temperature and number of PV cells connected in series and parallel. Figure 5.1 shows the simulink model of solar system. Here only function file used to show the solar system, the program code is given in the appendix. Here we are using a battery. The system is generated 240volt and current is 2.9 A.

The first ANN architecture design adopts the PV module temperature (TCell) in °Celsiusand the irradiance (E) in W/m2, as the inputs of the network and the PV generator output power (P) in Watt, as the output of the network. The data set are trained until new patterns may be presented to them forprediction or classification. Our purpose is to see the behaviour of the new obtained power values, compared to recorded experimental data with respect to the data set.

Think about solar energy and the first image that springs to the mind is that of those arrays of shiny photovoltaic panels adorning the rooftops and the countryside. Indeed, photovoltaic cells still remain the most popular way of generating solar power. Solar power, for one thing, is not cheap. However, even though the initial set up costs can be quite high, the long-term financial benefits of using solar power are too strong to deny.

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.

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.

Keep in mind that it is not likely that the chosen solar panels will receive the amount of sunlight that is available at the equator. Also, the actual amount of sunlight will vary throughout the day. Since it is best upon both the season and the weather, it isn't possible to use the maximum power rating to determine the exact power that will be seen from the solar panel. However, there are still ways to determine how well a panel will perform in a particular area. To learn this information, the average amount of sunlight that occurs in a particular area is necessary. With this information, one can calculate the best panel to purchase in order to receive the best

Solar power is not consistent or reliable enough to be the only option for power. This technology relies totally on the sun so certain days we will be able to produce more power than others and at night we might not be able to produce any. Which is why we will not be able to completely sever the tie to conventional power generation. There has to be a method available to generate enough power to meet demand without available sunlight. Although as technology progresses we may soon be able to generate power from solar sources 24 hours a day. Modern solar power towers are being designed to store excess heat transfer medium underground during the day as its heated and recycling it at night to continue to generate steam for power production (Mills, 2004). But even with this ability we will not be able to go solely to solar power but it can still supplement existing power and drastically reduce the country’s carbon

As one may know in order to use solar energy, one has to have access to sunlight. Even though one see the light of day, the sun will not always be out when you need it. In Source B it states, “solar power is not a constant source of energy.” Eventually when six o’clock comes around in the afternoon, the sun will set and later on the moon will appear in the night sky. This means that once the sun sets one won’t people able to do their daily chores because their solar panels on the roof isn't providing any electricity in the house.

Commonly, renewable energy is defined as energy which is able to be captured from existing natural resources that are replenished rapidly, such as flowing water, sunshine, wind, geothermal heat flows and ocean [2]. Renewable energy technologies are required to provide technologies to use one or several renewable energy resources. There are some different types of renewable energy technologies, which include solar energy, bioenergy, hydropower, wind energy, geothermal energy and tidal energy. This thesis project will focus on the solar photovoltaic which is currently one of types of solar energy technologies, and this technology using photovoltaic cells to converts sunlight directly into electricity.Solar photovoltaic system can generate electricity from sunlight through using PV modules, and the system can be integrated into building designs, installed on rooftops, or large scale power plant. With the development of photovoltaic technologies, solar photovoltaic capacity has been increased from 3.7 GW (2004) to 177GW (2014) [3]. Figure 2 shows this change from 2004 to 2014, there is a big trend of increase in these years. The increase of PV capacity can reduce the carbon emission and provides more job opportunities. It also helps to reduce air pollution and make a friendly environment for living. One of the common PV system is

Analysis of Building a Functioning Solar Panel that Could Produce Energy on Cloudy, Sunny, and Overcast Days.

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

PR = Performance ratio, (range between 0.5 and 0.9, default value = 0.75) (Photovoltaic-software.com, 2016)

Although solar energy is copiously accessible, it is likewise variable and discontinuous. Solar power can 't produce electricity during the evening without capacity components, and is less powerful in cloudy or overcast conditions. Hence, solar energy is frequently utilized as a part of conjunction with the base-load era from coal, regular gas, atomic, and hydro wellsprings of power that can save the period in times of irregularity.
