The lower section of the Rooftop Solar Tracker is a very important and integral part of the whole system. This section must fulfil several aims or User Requirement Specifications:
• To enable the tracker to sit on a horizontal plane, parallel to the plane of the Earth, thereby simplifying the geometry required to track the sun’s daily and annual motion.
• To provide a stable platform, that is able to carry the load of the Panels, batteries, motors, etc., above it.
• To provide a secure connection to the roof itself, and withstand any external force placed upon either itself or the apparatus placed above it.
• To provide a integrated weatherproof housing for the key components, such as motors, batteries and electronics
• Provide a connection path for the electrical circuitry between the solar panel, solar storage batteries and the mains supply inside the house.
In conjunction with the rest of the project, the design for this section must combine elegance, simplicity and efficiency. This section of the design is the main interface between the house and the rest of the Rooftop Solar Tracker. It was therefore very important that a clear understanding of how domestic roofs are constructed was established before the key design decisions were undertaken. It is also important to point out at this stage that since the solar panel is clearly stated as intended for domestic use alone, the roof attachment system was designed with a domestic house in mind.
The complete design for the Roof attachment and Platform system is shown below

The Future of Energy: Rooftop Solar Panels

...The Future of Energy: Rooftop Solar Panels Coal fired energy plants have long been recognized as extremely damaging to the environment. The role of carbon dioxide, a greenhouse gas, in precipitating climate change is well documented. Carbon-dioxide emissions have increased manifold since the Industrial Revolution and have led to an increase in the Earth’s temperature in the past 50 years, worsening forest fires, drought and coastal flooding among other disastrous side effects of climate change, according to the U.S. Global Change Research Program. (NOAA National Climatic Data Center). In Kentucky where 91% of its power is generated from coal (Department for Energy Development and Independence; Kentucky Coal Association), there is a great impetus for utilities to cut down on carbon emissions. Unfortunately current efforts to reduce carbon emissions are largely insufficient because they do not attempt to reduce America’s and Kentucky’s overreliance on fossil fuels such as coal and natural gas. Rather, currently adopted technologies like carbon capture and storage (CCS) and natural gas-fired plants that halve carbon emissions merely seek to reduce the environmental impact while still relying on fossil fuels for energy. (Nijhuis) (Breeze) For a solution to be viable in the long run, it must propose an alternative energy source to reduce our reliance on fossil fuels for energy which is the root cause of excessive carbon emissions. Investing in renewable energy like solar power is...

Parks

...much of these building materials, cities are usually warmer than surrounding rural areas. Parks and other green spaces help to mitigate the Urban Heat Island Effect. Unfortunately, many cities cannot easily create more parks because most land is already being used for buildings, roads, parking lots, and other essential parts of the urban environment. However, cities could benefit from many of the positive effects of parks by encouraging citizens to create another type of green space: rooftop gardens. While most people would not think of starting a garden on their roof, human beings have been planting gardens on rooftops for thousands of years. Some rooftop gardens are very complex and require complicated engineering, but others are simple container gardens that anyone can create with the investment of a few hundred dollars and a few hours of work. Rooftop gardens provide many of the same benefits as other urban park and garden spaces, but without taking up the much-needed land. Like parks, rooftop gardens help to replace...

Stereoscopic Building Reconstruction Using High-Resolution Satellite Image Data

...neural network is employed in the grouping process. Prior to the grouping process, 3D line segments are extracted with the aid of the elevation information obtained by using area-based stereo matching of satellite image data. High-resolution IKONOS stereo images are utilized for the experiments. The experimental result proved the applicability and efficiency of the approach in dealing with 3D building modeling from high-resolution satellite imagery. Index Terms—building model, satellite image, 3D modeling, line segment, stereo I. I NTRODUCTION Extraction of 3D building model is one of the important problems in the generation of an urban model. The process aims to detect and describe the 3D rooftop model from complex scene of satellite imagery. The automated extraction of the 3D rooftop model can be considered as an essential process in dealing with 3D modeling in the urban area. There has been a significant body of research in 3D reconstruction from high-resolution satellite imagery. Even though a natural terrain can be successfully reconstructed in a precise manner by using correlation-based stereoscopic processing of satellite images [1], 3D building reconstruction remains to a difficult process, due to the discontinuity of elevation in manmade objects. In this context, most studies rely on 3D feature analysis. Perceptual grouping technique [2] has been broadly used for detecting and describing buildings in aerial or satellite image. This traditional method demonstrates the...

...climate change, food crisis and so on. Many scientists spend their whole lives in order to find out good solutions to the world’s problems. Even some of the scientists died while discovering the explanations because they were stressful of work or they were being poisoned by toxic chemicals. All people are respectful to scientists because of their enormous contributions to humankind. When I decide to pursue my major-electrical engineering, I also aim at figuring out an efficient way to reduce the gas emission. I think about how to make use of the solar energy in the production of solar panel on rooftop, electricity-generating devices. Truthfully, the solar energy is very important to the world. The fossil fuels cannot remain sufficient; therefore, oil and gas supplies will go down and cannot bring enough for demand. The solar energy will be the best option for a long term. Solar panel on the rooftop will focus the sun’s rays to heat fluids that produce power so that it can help engines act. Solar energy makes the productivity higher. However, the use of solar energy in production is still low due to the manufacturing high cost. In the future, if all people tend to use more solar energy, the manufacturing cost will decrease so that it can fit to the majority. Furthermore, the storing of solar energy is also considered deeply. If people constantly use an energy source without storing for later use, that source will become disappear. Those are the things I am going to do in the future...
