All about Solar Mounting

       The high rise in fuel and energy costs is not going to subside anytime soon. It is this reality that most households are turning to alternative means like solar outdoor lighting. This is the most efficient way to curb the high costs of energy and make huge savings on your monthly energy bills. Relying on solar though expensive in the initial cost of purchasing equipment for solar mounting, is an expense saving option that will pay up its initial cost and continue saving you on the monthly energy bills. This is because solar energy is absolutely free and you alone are to decide how much of it you need.

       When it comes to solar energy, the one question that most people grapple with is how to increase the efficiency and output of their systems. There are two solutions to this problem. One is to increase the number of solar panels one is having and the second method is to increase the efficiency of the existing panels. The second option largely depends on the kind of solar mounting in place and is much cheaper. It calls for the use of solar rack to increase the panels’ exposure to the sun to tap more solar energy. The conventional way of solar mounting has been to use a roof rack where the panels are raised on the roof for sunlight exposure. However, this method of solar mounting faces serious challenges when there is the presence of trees and other obstacles as this will limit the sun exposure.

       One can also make use of manually or automatically adjustable awnings to maximize sun exposure. There are many advantages that come with the use of solar outdoor lighting. One is the obvious aspect of saving on the cost of energy because you will be using free energy especially with proper solar mounting. Another advantage is that they are easy to maintain and safe in that their bulbs light low, hence cannot burn children or pets. They are also environmental friendly. This helps reduce the carbon emissions. They also do not cause extra heating in the house thus eliminating the need for air conditioning.

The Solar Street Light Saves the Energy from Wind and Solar Power

       If you still don’t know what solar street light is, you are definitely out of date! In recent year, people start to reconsider the use of energy. Since the dominant energy source, oil, has become more and more expensive, for the storage reduce continuously, engineers and scientists begin to search other substitute energy source. Other than that, experts warn that our earth has been polluted seriously by human beings. Therefore, the green energy should be value more than any other time. Solar energy, one of the substitute energy, is eco-friendly and without any pollution. It can generate power just by sun light.

       Solar energy is not available at night, making energy storage an important issue in order to provide the continuous availability of energy. Both wind power and solar power are intermittent energy sources, meaning that all available output must be taken when it is available and either stored for when it can be used, or transported, over transmission lines, to where it can be used. Wind power and solar power tend to be somewhat complementary, as there tends to be more wind in the winter and more sun in the summer, but on days with no sun and no wind the difference needs to be made up in some manner. That’s the basic concept of how solar street light operate, using both wind power and solar power to generate electric. The Institute for Solar Energy Supply Technology of the University of Kassel pilot-tested a combined power plant linking solar, wind, biogas and hydrostorage to provide load-following power around the clock, entirely from renewable sources.

       Daylighting systems collect and distribute sunlight to provide interior illumination. This passive technology directly offsets energy use by replacing artificial lighting, and indirectly offsets non-solar energy use by reducing the need for air-conditioning. Although difficult to quantify, the use of natural lighting also offers physiological and psychological benefits compared to artificial lighting. Daylighting design implies careful selection of window types, sizes and orientation; exterior shading devices may be considered as well. Individual features include sawtooth roofs, clerestory windows, light shelves, skylights and light tubes. The solar outdoor lighting may be incorporated into existing structures, but are most effective when integrated into a solar design package that accounts for factors such as glare, heat flux and time-of-use. When daylighting features are properly implemented they can reduce lighting-related energy requirements by 25%.

How to Generate Solar power by Solar Panel and Solar Rack?

       Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems, including solar panel and solar rack to focus a large area of sunlight into a small beam. Photovoltaics convert light into electric current using the photoelectric effect.
       Concentrated photovoltaics (CPV) systems employ sunlight concentrated onto photovoltaic surfaces for the purpose of electrical power production. Solar concentrators of all varieties may be used, and these are often mounted on a solar tracker in order to keep the focal point upon the cell as the Sun moves across the sky. Luminescent solar concentrators (when combined with a PV-solar cell) can also be regarded as a CPV system. Luminescent solar concentrators are useful as they can improve performance of PV-solar panels drastically. The fixed solar rack in the solar panel holds panels in a single location as the sun moves across the sky.

Solar Outdoor Lighting Saves the Energy

      The reason why we have solar outdoor lighting is because energy saving becomes a more and more popular issue nowadays. Solar outdoor lighting is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP) or to split water and create hydrogen fuel using techniques of artificial photosynthesis. Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics convert light into electric current using the photoelectric effect.
      In the 20th century artificial lighting became the main source of interior illumination but daylighting techniques and hybrid solar lighting solutions are ways to reduce energy consumption.
      Daylighting systems collect and distribute sunlight to provide interior illumination. This passive technology directly offsets energy use by replacing artificial lighting, and indirectly offsets non-solar energy use by reducing the need for air-conditioning. Although difficult to quantify, the use of natural lighting also offers physiological and psychological benefits compared to artificial lighting. Daylighting design implies careful selection of window types, sizes and orientation; exterior shading devices may be considered as well. Individual features include sawtooth roofs, clerestory windows, light shelves, skylights and light tubes. They may be incorporated into existing structures, but are most effective when integrated into a solar design package that accounts for factors such as glare, heat flux and time-of-use. When daylighting features are properly implemented they can reduce lighting-related energy requirements by 25%.
      Solar lights that charge during the day and light up at dusk are a common sight along walkways. Although daylight saving time is promoted as a way to use sunlight to save energy, recent research has been limited and reports contradictory results: several studies report savings, but just as many suggest no effect or even a net loss, particularly when gasoline consumption is taken into account. Electricity use is greatly affected by geography, climate and economics, making it hard to generalize from single studies.

Solar Rack Helps to Sustain the Solar Panel

       A solar panel is a packaged, interconnected assembly of solar cells, also known as photovoltaic cells. And the solar rack is used to sustain the solar panels. The solar panel can be used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications. Because a single solar panel can produce only a limited amount of power, many installations contain several panels. A photovoltaic system typically includes an array of solar panels, an inverter, and sometimes a battery and interconnection wiring.
       The whole solar mounting system is composed by trackers, fixed solar rack, ground mounted systems, and roof mounted systems.
  1. Tracker: Solar Trackers increase the amount of energy produced per panel at a cost of mechanical complexity and need for maintenance.
  2. Fixed Solar Rack: it hold panels in a single location as the sun moves across the sky. It can set the angle at which the panel is held. Tilt angles equivalent to an installation's latitude is common.
  3. Ground Mounted System: Ground Mounted solar power systems consist of solar panels held in place by racks or frames which are attached to ground based mounting supports.
  4. Roof Mounted Systems: Roof Mounted solar power systems consist of solar panels held in place by racks or frames which are attached to roof based mounting supports.
